Family - Ranunculaceae Stems - To +50cm tall, glabrous, from thick large rhizome, herbaceous, purplish at base.
Leaves - Alternate, twice ternately divided, glabrous, petiolate. Ultimate divisions serrate, with shallow lobes. Total leaf length(with petiole) +40cm long, +30cm broad. Inflorescence - Axillary pedunculate raceme with +/-15 flowers, to 10cm long(tall). Peduncle to +15cm, glabrous. Pedicels thick, 1cm long, 1.5mm in diameter, thickened at apex, with antrorse pubescence. Small acuminate bract subtending each pedicel. Peduncle and pedicels enlarging and becoming red in fruit. Flowers - Petaloid sepals 4-5, white, truncate to 3-notched at apex, 5mm long, 1.5mm broad. Stamens +20. Filaments to 6-7mm long, white, glabrous, slightly expanded(thickened) just below anthers. Anthers pale yellow, .6mm in diameter. Ovary superior, white, glabrous, 3mm long, 2mm broad, urceolate. Placentation parietal. Stigma capitate, 2-lobed. Fruit - A white subglobose berry with +/-5 seeds. Berry with black dot at apex, to 1cm long, with vertical groove.
Flowering - May - June. Habitat - Ravines, rich thick woods, north facing slopes, base of bluffs. Origin - Native to U.S. Other info. - The species name means "thick foot" and one look at the big rhizome of the plant shows that it is aptly named. The rhizome used to be used, and probably still is, to treat pain and bronchial troubles. The plant is toxic however and some people get violent gastric distress from ingesting it. The plant can cause skin irritation also. The plant grows in such thickly wooded areas that my photos came out fuzzy due to the lack of light while shooting. The fruits of the plant are striking and add nice color to the deep forest floor in the early fall.

Family - Fabaceae Stems - Multiple from a woody crown, to 1m tall, red in strong sunlight, carinate, stout, erect, branching, herbaceous to suffrutescent, with pustulate-based hairs (the base of the hairs giving the stems a scabrous feel).
Leaves - Alternate, petiolate, stipulate, bipinnate (even), to +15cm long. Petioles to 3cm long, lacking glands. Expanded portion at the base of the petiole to 3mm long. Petioles and rachis with shallow adaxial groove, pubescent as the stem. Stipules thin and dry, ferruginous, ~3mm long, ~.5mm wide, with ciliate margins, other wise glabrous. Pinnae opposite to sub-opposite, +/-11 per side. Petiolules of pinnae -1mm long, antrorse pubescent. Leaf divisions with many pinnules (+/-50 per margin). Pinnules -4mm long, -1.5mm broad, acute, entire, oblique at the base, dull green above, light green below with a dark green midrib, with a few sparse hairs at the margins.
Inflorescence - Pedunculate, axillary globose clusters mostly in the apical half of the stem. Peduncles light green, sparse antrorse pubescent, carinate, +/-2cm long. Pedicels light green, to 1mm long. Flowers +/-25 per head. Flowers - Petals 5, green, erect, united at the very base, glabrous, acute, to -3mm long, 1mm broad, oblong elliptic. Calyx greatly reduced, .7mm long with very shallow lobes. Stamens very numerous (+100), well exserted from the perianth. Filaments white, glabrous, 5-8mm long, capillary. Anthers pale yellow, .1mm broad. Ovary superior, green, 1-1.2mm long in flower, .5mm in diameter, cylindric, subtended by a yellow ring-like nectary. Stipe .5-.7mm long. Style 1, as long as the filaments, light green, 3-4mm long. Fruits not seen. Flowering - June - October. Habitat - Rocky glades, open hillsides, exposed ledges along bluffs. Origin - Native to U.S., Central and South America, Australia, Africa. Other info. - This species can be found in the southwest corner of Missouri. The plant reaches the northeastern edge of its range in Missouri. It is much more common in the southwestern U.S. The plant can be identified by its bipinnate leaves and globose clusters of flowers. Another species, Desmanthus illinoensis (Michx.) MacM., is similar but has glands on its leaf petioles and fewer stamens per flower (5). This latter species is weedy in Missouri and can be found throughout the state.

Family - Caprifoliaceae Stems - Woody, multiple or occasionally single. A shrub or small tree to 6m tall. Twigs dense with ferruginous or grayish stellate hairs. Leaves - Opposite, petiolate, elliptic, somewhat cordate at base or not, to +15cm long, +7cm broad, upper surface glabrous or with some stellate pubescence, lower surface densely stellate pubescent, margins with minute prickles or protrusions. Petioles densely stellate pubescent.
Flowers - Corolla 5-lobed, to 8mm broad, whitish, glabrous. Lobes rounded, -2mm long and broad. Stamens 5, alternating with lobes, borne at base of corolla tube, erect and exserted well beyond corolla. Filaments to +4mm long, glabrous, whitish. Anthers yellow-brown, to 1.1mm long. Calyx tube to 1.5mm long, stellate pubescent. Lobes minute. Fruits to 8mm long, ovoid, single seeded(drupes), red at first, ripening to purplish-black.
Flowering - May - June and sometimes again around November. Habitat - Cultivated. Origin - Native to Eurasia. Other info. - This plant is very commonly cultivated in Missouri. The hairs of the plant cause irritation to some people, like myself. The fruits are interesting in that the entire cluster does not ripen at once so both red and black fruits are present at the same time giving the plant added color. The flowers of this plant are not as fragrant as other plants in this genus which bloom around the same time.

Lobes 3mm long and wide. Stamens 5, borne at base of corolla tube, well exserted, erect. Filaments to 4mm long, glabrous. Anthers yellow, to 1.2mm long. Style thick, .7mm long. Calyx tube to 2mm long, 1.2mm in diameter, glabrous, 5-lobed. Lobes to .8mm broad, .5mm long. Fruits purplish-black, ellipsoid to globose, to +1cm long, single-seeded (drupes).
Flowering - April - May. Habitat - Low woods, moist soils, slopes, thickets. Also cultivated. Origin - Native to U.S. Other info. - This species can be found throughout Missouri but is apparently absent from a few counties in the extreme northwest corner of the state. The plant can be identified by its opposite leaves (which resemble those of the genus Prunus or Pyrus), its tan, thin leaf buds, and its big clusters of white flowers. The fruits of this species are edible. The plant has been cultivated for some time and would make a good garden specimen plant.

Family - Caprifoliaceae Stems - Woody, multiple. A shrub to 5m tall. Twigs appearing somewhat glaucous but actually glabrous. New seasons growth glabrous, 5(6)-angled, with longitudinal grooves. Leaves - Opposite, petiolate, typically rounded but sometimes slightly cordate at base, toothed, orbicular to broadly-ovate, to 7.5cm long, lower surface dull green with tufts of hairs mostly in vein axils or on veins, upper surface shiny deeper green, glabrous. Inflorescence - Terminal, compound cymes (resembling compound umbels), to +13cm broad. Pedicles glabrous or with ferruginous stalked and sessile glands. Small scarious bracts present at base of each division of inflorescence.
Flowers - Corolla white, 4-5mm broad, 5-lobed, glabrous internally or with very few sparse hairs, glabrous externally, tube to 1.2mm long, 2-3mm broad, campanulate. Stamens 5, well exserted, alternating with corolla lobes. Filaments to 4mm long, white, glabrous, borne at base of corolla tube. Anthers yellow, .6mm long. Calyx tube to 2mm long, 1mm broad, cylindric, glabrous, 5-lobed. Lobes greenish-white, very small, tuberculate.
Flowering - May - June. Habitat - Low alluvial woods on terraces and wooded slopes. Widely cultivated. Origin - Native to U.S. Other info. - This plant is just one of the many species in this genus cultivated in Missouri. The plant can be identified by its suborbicular, dentate leaves (which have deeply impressed lateral veins). Natives used the wood from the tree to make arrows for hunting. They also used the inner bark as a tobacco substitute.

Family - Scrophulariaceae Stems - To 1.75m tall, branching above or not, erect, herbaceous, glabrous to pubescent or villous.
Leaves - Whorled, up to 7 at a node but typically four or five, sessile to very short petiolate. Blade lanceolate to linear oblong, serrate, to +12cm long, +2cm broad, glabrous above, dense pubescent below.
Inflorescence - Terminal spikiform racemes to 20cm long(tall), densely flowered, indeterminate. Pedicels to .5mm long. Each flower subtended by a small attenuate bract to 1.1mm long. Flowers - Corolla subbilabiate, white (sometimes pinkish), glabrous. Corolla tube to 6mm long. Upper lip single lobed. Lobe to 1.5mm long, rounded. Lower lip 3-lobed. Lobes rounded, to 1.5mm long. Stamens 2, exserted, adnate near base of corolla tube. Filaments pubescent at base, white, to 1.3cm long. Anthers orange, to 1.3mm long. Style glabrous, brown, included, to 7mm long. Ovary green, glabrous, superior, 1mm long, with deep green nectariferous ring at base. Locules 2. Placentation axile. Fruit a terete capsule to -5mm long, many seeded. Calyx subbilabiate, the sepals appearing almost distinct. Lobes lanceolate, to 1.5mm long, acute, glabrous, green. Lower lobes typically a bit longer than the upper lobes. Flowering - June - August. Habitat - Moist to wet open ground, rich open woods. Origin - Native to U.S. Other info. - This plant is easily identified as nothing else in the state's flora resembles it. The plant is being cultivated more frequently and adds a brilliant white splash of color to any landscape. It also re-seeds easily. A common name for the plant is "Veronica" which is bad because the genus Veronica is in the same family but the plants are totally different. Just another reason to learn the scientific names.

Upper leaves sessile, to 2cm long, 6-7mm broad, glabrous to glandular pubescent, oblong to oblanceolate, coarsely serrate to crenate-serrate, reduced to foliaceous bracts in inflorescence.
Inflorescence - Loose terminal raceme. Flowers appearing as single axillary flowers because of subtending foliaceous bracts. Flowers - Corolla deeply 4-lobed, white, glabrous, to 4mm long. Lobes 2mm long, to 2mm broad, obtuse at apex. Stamens 2, included to slightly exserted. Style short, to .3mm long. Ovary obcordate, compressed, glabrous to glandular pubescent, green. Calyx deeply 4-lobed. Lobes 4-5mm long, 1.1mm broad, linear-oblong, glabrous, erect. Capsule to +/-4mm long and broad at apex, obcordate, glabrous to glandular pubescent. Flowering - April - August. Habitat - Moist ground, roadsides, railroads. Origin - Native to U.S. Other info. - This plant is very small and the flowers are inconspicuous and often overlooked. The flowers also wilt quickly when hit with hot direct sun. This species is common throughout Missouri and can grow anywhere if the soil is moist. Steyermark lists two varieties for the state. Variety peregrina is glabrous throughout, and var. xalapensis (HBK.) Pennell is glandular pubescent.

Family - Liliaceae Stems - From a rhizome and thickened roots, to -15cm tall, erect, single from the base, simple, herbaceous, glabrous, reddish, somewhat 5-angled.
Leaves - 3, whorled, petiolate. Petioles 3-4mm long, mostly glabrous but minutely translucent papillate on the margins (use a lens to see). Blades ovate, to +3cm long, +1.5cm broad, shiny silvery-green below, pale bluish-green above, glabrous above, translucent papillate below, acute to subacute at the apex, entire, with papillae on the margins (use a lens to see papillae), with 5 main veins. Lateral veins reticulate. Veins impressed above, expressed below.
Inflorescence - Single flower terminating the stem. Peduncle to +1.5cm long, glabrous, purplish. Flowers nodding slightly or erect. Flowers - Petals 3, white, glabrous, to 3cm long, +1cm broad, oblong to elliptic, entire, blunt to slightly emarginate at the apex, tapering to the base, distinct. Stamens 6, alternating smaller and larger, erect, distinct. Filaments to 5mm long, -1mm broad, white, slightly compressed. Anthers yellow, to +6mm long, -2mm broad, longitudinally dehiscing. Anther connective greenish. Styles 3, erect. curled at the apex, to 1cm long, white at the apex, yellow to greenish basally, distinct. Ovary sessile, yellowish, superior, glabrous, 3-lobed, 3mm long and broad, 3-locular, with many ovules. Placentation axile. Sepals 3, green, slightly spreading, +/-2cm long, 5-6mm broad, lanceolate, blunt to slightly emarginate at the apex, with 5 parallel veins, with a scarious margin .1mm thick, glabrous. Flowering - March - April. Habitat - Mesic upland forests on steep, open, north-facing slopes above streams and rivers - on limestone and chert substrates. Origin - Native to U.S. Other info. - This small species is the smallest Trillium in Missouri and the first to bloom each spring. The plant is uncommon in the state and can only be found in a handful of counties. Its very selective habitat limits its range in Missouri. T. nivale is an easy species to identify in the field (if you're lucky enough to find it) because of its small size, habitat, and white flowers. Plants are usually found in large numbers in a given area.
