Family - Fabaceae
Stems - Multiple from base, from taproot, ascending, to 50cm long, glabrous, tinted with red, herbaceous, sometimes fistulose.
Leaves - Alternate, petiolate, trifoliolate, stipulate. Stipules entire, glabrous, with reticulate venation throughout, to 2cm long, +5mm broad, acuminate. Petioles to 1cm long, glabrous, green. Leaflets subequal, on petiolules to 1mm long, glaucous below, dull green above, orbicular to broadly ovate, +/-2cm long, and broad. Margins denticulate to serrulate or stigillose from leaf venation extending beyond margin.
Inflorescence - Globose axillary pedunculate clusters of stalked flowers. Flowers +/-50 per cluster. Peduncles to -10cm long. Pedicels to +3mm long, pubescent, reflexed with maturity.
Flowers - Corolla papilionaceous, whitish at first - soon becoming pinkish - turning rose upon drying. Standard 4mm broad. Stamens diadelphous, connected for 2/3 of length. Style 2.5mm long. Ovary green, 2.2mm long. Calyx tube to 1.5mm long, 1.1mm in diameter, whitish, pubescent, 5-lobed. Lobes green, 1.2mm long, coarse pubescent. Fruit to +/-7mm long, glabrous, with +/-2 seeds.
Flowering - May - October.
Habitat - Fields, pastures, waste ground, disturbed sites, roadsides, railroads.
Origin - Native to Eurasia.
Other info. - Yet another introduced member of the genus Trifolium. This plant is scattered throughout Missouri and grows in much of the U.S. and Canada. It was introduced as fodder and has subsequently spread. Our plants belong to var. pratense Rabenh. (synonymous with var. elegans (Savi) Asch. & Graebn.). Another variety, var. hybridum is larger and more commonly cultivated (mostly northward), but does not appear in our state, yet.
The plant is high in protein but can cause skin irritation in some people.

Family - Commelinaceae
Stems - To +50cm tall, simple, from thickened roots, herbaceous, glabrous to hirsute, glaucous, somewhat succulent.
Leaves - Alternate, sheathing at base, to -30cm long, +/-4cm broad, glaucous above and below (less so above), glabrous, ciliate margined, narrowly lanceolate.
Inflorescence - Terminal, bracteate, umbellate cymes of +/-15 flowers. Pedicels +/-3cm long, glandular pilose, strongly recurving in fruit.
Flowers - Petals 3, white to pink or lilac, glabrous, broadly ovate, +/-2cm long and broad, distinct. Stamens 6. Filaments 3mm long, white, with dense multicellular hairs attached mostly in lower half, (hairs longer than filament). Anthers yellow, 2mm broad, 1mm long. Style 1, glabrous, 2-3mm long. Ovary superior, 3-locular, (one ovule per locule), with erect gland-tipped hairs on summit. Sepals 3, ovate, acute, glandular pilose externally, glabrous internally, +/-8mm long, 4mm broad, free, accrescent.
Flowering - April - May.
Habitat - Slopes, woods, bluff ledges.
Origin - Native to U.S.
Other info. - This is a nice plant because it's not the usual T. ohiensis, which, while striking, is very common.
T. ozarkana can have variably colored flowers. I also photographed this pinkish-lilac colored flower:
The stems are typically glabrous but the white flowered plants shown above all had hirsute stems. In the "Flora of Missouri" Steyermark writes that he found plants with hirsute (densely pubescent) stems in Taney County, which is where these photographs were taken. Julian Steyermark was the man.
The plant can be found in rich, rocky areas of the habitats mentioned above.

Family - Apiaceae
Stems - To +1m tall, from thick taproot, multiple from base, branching, herbaceous, erect, retrorse strigose, scabrous.
Leaves - Alternate, pinnately divided, petiolate. Petiole involute, scabrous, retrorse strigose, sheathing(on lower leaves). Lobes of lower leaves typically pinnatifid. Ultimate leaf divisions serrate(the teeth mucronate).
Inflorescence - Axillary and terminal compound umbels. Axillary umbels actually opposite the leaves. Peduncles to 10cm long, retrorse strigose. Rays 5-7, antrorse stigose, subtended by 1-3 bracts. Bracts linear, to 1.5cm long, antrorse strigose, typically unequal. Umbellets subtended by +/-8 bractlets. Bractlets to 5mm long, linear-lanceolate, antrorse strigose. Raylets +/-3mm long, antrorse strigose.
Flowers - Petals 5, white, unequal, free, antrorse strigose externally, glabrous internally, deeply cleft with an inflexed central appendage, the largest to 2mm long and broad. Stamens 5, alternating with petals, small. Styles 2, .5mm long, green, with expanded stylopodium. Stigma globose. Ovary inferior. Sepals 5, much reduced, alternating with petals, acute, to .4mm long. Fruit 8-ribbed, with uncinate bristles on ribs(to 2mm long), glandular and regular pubescent, to 5mm long, 3mm broad.
Flowering - June - August.
Habitat - Waste ground, disturbed sites, thickets, roadsides, railroads.
Origin - Native to Eurasia.
Other info. - If you've ever had the unfortunate predicament of walking through a mass of these plants you realize why the plant has spread so rapidly in such a short time, being introduced for just about a century. The fruits grab hold of nearly any fabric and any hairy appendage which happens to be exposed. The task of removing the fruits is less than enjoyable.
Synonyms include T. arvensis (Huds.) Link and T. anthriscus (L.) Bernh. - Rydberg.

Inflorescence - Axillary open pendulous cymes from new seasons growth, with 5-8 flowers. Peduncle adnate to white bract for about half it's length, glabrous. Bract to +/-8cm long, to -1.5cm broad, glabrous except for few hairs near axil with peduncle, creamy-white. Pedicels to 7.5mm long, green, 1mm in diameter, glabrous.
Flowers - Petals 5, greenish-white, alternating with sepals, 7.5mm long, 3mm broad, cupped. Stamens many. Filaments white to pale yellow, to 4mm long, glabrous. Anthers yellow, 1mm long. Style 5mm long, mostly glabrous but with tufts of hairs near base. Ovary globose, 2.1mm in diameter, tomentose, 5-locular. Sepals 5, free, ovate-lanceolate, to 6mm long, 3mm broad, greenish white, with nectary at base, (appearing as translucent hump). Fruit ovoid to spherical, 4-5mm in diameter, tomentose, with typically 1 or 2 seeds. Flowers fragrant.
Flowering - May - July.
Habitat - Moist soils along stream banks and pond margins. Also in low woods.
Origin - Native to U.S.
Other info. - The wood of this species is highly desirable for furniture making because of its soft yet strong nature and its beautiful white color.
Many cultivated varieties of the genus Tilia are planted in this state, some are from the native trees, some are the European and Asian species. All the trees are visited heavily by insects when blooming.
Steyermark lists two varieties for this species. Variety americana (pictured above) has glabrous petioles, peduncles and bracts. The leaves have hairs in the axils of the nerves. Variety neglecta has stellate and simple hairs on the lower leaf surface with the bracts and peduncles being variously pubescent.

Leaves - Basal leaves in rosette, petiolate. Petiole to 2cm long, glabrous. Blade to 3cm long, 1.5cm wide, ovate, elliptic or oblong, glabrous, coarsely toothed. Cauline leaves clasping, auriculate, glabrous, glaucous, entire to coarsely toothed, reduced upward.
Inflorescence - Terminal raceme. Compact in flower, becoming elongated in fruit to +10cm. Pedicels to 4mm long in flower, expanding in fruit to 6mm, filiform, glabrous.
Flowers - Petals 4, white, glabrous, spatulate to oblanceolate, to 2.5mm long, 1mm broad. Stamens 6, didynamous. Filaments 1.2mm long, glabrous, white. Anthers yellow, .2mm long. Style 1, very short, to .2mm long. Ovary green, superior, compressed, ovoid to rotund, 1mm long. Sepals 4, distinct, to 1.5mm long, 1mm broad, green with whitish margins, subacute at apex, ovate-oblong. Silicle to 6mm long, winged, obcordate, notched at apex, glabrous.
Flowering - March - May.
Habitat - Roadsides, waste ground, rocky outcroppings and open ground.
Origin - Native to Europe.
Other info. - Yet another one of the introduced plants from the Brassicaceae which dominate the early springtime. The stems of this plant appear to pass through the leaves, hence the name "perfoliatum" from "perfoliate." "Thlaspi" comes from the Greek name of cresses - "thlaspis".
This plant is common and locally quite abundant. The fruits slightly resemble those of Capsella bursa-pastoris (L.) Medic. but the latter has fruits which are more triangular in shape and are smaller when mature. The leaves of both plants differ greatly from one another.

New flower I received at a plant exchange this June. There was no tag on it when I got home; it must've gotten lost on the way, it was chaos at that exchange. My first one ;))
Interesting plant: I received it in several stems so I planted it en mass figuring I'll know what to do when it grows up. It's now about 18" tall, & the top leaves near the flowers just turned variegated. It's not fragrant, the flowers are white & tiny.
Anyone have any idea what it is?

Family - Ranunculaceae
Stems - To 2m tall, erect, glabrous, purple, herbaceous, fistulose, from caudex, branching above or simple, typically single from base.
Leaves - Lowest leaves petiolate, middle and upper leaves becoming sessile, all leaves ternately compound. Leaflets green, typically 3-lobed, typically longer than broad, glabrous to puberulent below, to 5cm long, 4cm broad. Lobes acute, sometimes divided. Margins sometimes slightly revolute.
Inflorescence - Plants dioecious. Staminate inflorescence a large open terminal panicle, very showy. Pedicels 5-6mm long, glabrous, each subtended by a small attenuate bract to 1.5mm long. Pistillate inflorescence paniculate, terminal, not showy. Peduncles to 5mm long, glabrous.
Flowers - Staminate flowers apetalous. Sepals 4, white, elliptic-lanceolate, 3mm long, 1.7mm broad, glandular pubescent externally, glabrous internally, fugacious. Stamens +/-12 in number. Filaments white, slightly clavate, 4mm long, glabrous. Anthers yellow, 1.2mm long, -1mm broad, apiculate. Pistillate flowers with +/-10 carpels. Styles whitish at apex. Sepals green, +/-2mm long.
Flowering - May - July.
Habitat - Low moist ground, ravines, streambanks, thickets, roadsides.
Origin - Native to U.S.
Other info. - This species is common throughout much of Missouri but appears to be mostly absent from the Ozark region. The staminate plants can be quite showy in flower but the pistillate plants are often overlooked. This species and another, T. revolutum DC., can be very difficult to distinguish from one another. A third species, T. diocum L., is easier to distinguish because it blooms in the spring and has middle and uper leaves which are long petiolate instead of sessile.

Leaves - Basal rosette, few, ovate, to +3cm long, +1.5cm wide. Absent at flowering time (anthesis).
Plant rarely with small cauline leaves (bracts).
Inflorescence - Single spike to 9cm long, with some 25 flowers in a single spiral, flowers appearing secund on the axis.
Flowers - Corolla white, glabrous, small, 2.5-4mm long, lip erose to undulate or crisped (curled).
Flowering - August - October.
Habitat - Acid soils of upland pine, oak, or hickory forest (associated with granite, chert or sandstone substrata). Also in dry upland prairies and meadows.
Origin - Native to U.S.
Other info. - This is a fairly common species in Missouri. The plant can be identified by its tiny white flowers which are in a single spiral around the axis of the inflorescence. Each plant typically has one tuberous root but some plants have the tuberous root persisting from the previous season and thus have two roots.

Stems - Aerial stems green, glabrous below, densely short glandular pubescent just below the inflorescence, to +50cm tall, erect, herbaceous, simple, terete, 3-5mm in diameter, single from the base.
Leaves - Mostly basal, few, linear to linear-oblong, to 25cm long, 2.5cm broad, present or (typically) absent at anthesis. Cauline leaves reduced to scales. The scalelike leaves to 3cm long, sheathing, acuminate, entire, glabrous 3-6 per stem.
Inflorescence - Terminal twisted spike to +/-12cm long. Flowers in two ranks, sometimes the two ranks are so mingled that no spiraling is visible. Flowers sessile. Each flower subtended and partially enveloped by a single acuminate bract. Bracts to +/-1.2cm long, +/-5mm broad (at the base), pubescent, with broad scarious margins in the basal 1/2, the apices abruptly acuminate.
Flowers - Corolla white, to +1cm long, slightly drooping. Lateral sepals white, with in-rolled margins, running parallel to the rest of the flower, pubescent, 7-8mm long, subulate. Upper 3 petals white, 7-11mm long, -2mm broad, appearing connate and forming the upper lip of the flower, pubescent. Lower petal white, more stout than the upper petals, 7-11mm long, 3-4mm broad, crisped (sometimes slightly) at the apex, somewhat folded, mostly glabrous, with two basal projections to 1.5mm long. The projections slightly retrorse, densely pubescent except at the apex. Pollinia 3mm long, with their bases (terminator) facing forward and slightly exserted from the column. Terminator brownish-red. Column 3-4mm long, with a brownish-red triangular lobe and two greenish lobes at the apex. Floral tube green, 5-6mm long, densely pubescent.
Flowering - August - November.
Habitat - Acidic glades, dry upland prairies, wet meadows, thickets.
Origin - Native to U.S.
Other info. - This is a very common orchid in this state. The plants species name means "nodding" and the flowers do nod slightly. This species can be differentiated from others in the genus by its big flowers, which have the lateral sepals paralleling the sepals, and its lack of basal leaves at anthesis.
