Blades variable, from lanceolate to ovate or oblong, serrate, acute to acuminate, slightly scabrous above, velutinous below (and often bluish-green in color), with many small teardrop-shaped granules below, to 15cm long, 8-9cm broad. The serrations of the margins often with a minute whitish apex. Veins of the leaf blade are impressed adaxially and expressed abaxially.
Inflorescence - Dense cymose arrangement of flower heads. Peduncles velutinous, to 2cm long.
Involucre - 7-8mm long (tall), 5-6mm in diameter. Phyllaries imbricate, green with purple margins and midrib, acuminate, with arachnoid pubescence externally, glabrous internally, to 6mm long, 2-3mm broad. The tips of the phyllaries typically spreading but sometimes appressed. Margins often fimbriate-
Ray flowers - Absent.
Disk flowers - Corolla deep pink, 5-lobed, glabrous. Tube to 1.2cm long. Lobes to 3mm long, recurved, glabrous, linear. Stamens 5, adnate in upper 1/3 of corolla tube. Filaments white, glabrous.

Flowering - May - September.
Habitat - Fields, prairies, rocky woods, glades, meadows, waste ground, pastures, thickets, roadsides, railroads.
Origin - Native to U.S.
Other info. - This striking species is found throughout Missouri. The plant is common in the habitats listed above. This and other species of Vernonia can be fairly variable and sometimes difficult to ID. Many of the plants in this genus form hybrids and thus make ID even more of a challenge. V. baldwinii grows well from seed and should be used more in cultivation. Flying insects are very fond of the flowers.
Steyermark breaks this species down into different varieties and forms. I won't go into those here as many of these integrate and are probably not valid.

Pedicels .5-2mm long, retrorse pubescent. Bracts subtending the calyx ovate to ovate-lanceolate, 1mm long, .6mm broad, shorter than the calyx tube, rounded to subacute at the apex, glabrous adaxially, strigose abaxially.
Flowers - Corolla papilionaceous, pink. Standard pink, 1.5-1.9cm broad, 1.2cm tall, emarginate at the apex or not, glabrous. Wings pink at the apex, rounded with a short claw (to 2mm long), glabrous, 1cm long, 5mm broad, free from keels. Keels white but wine-purple at the apex, strongly deflexed and surrounding the fertile floral organs, glabrous externally, connate on lower margin. Stamens diadelphous, the tube white and glabrous, deflexed and connate around the style. Free portions of stamens 5-6mm long. Anthers yellow, .7mm long. Ovary green, superior, 5-6mm long in flower, sericeous. Calyx bilabiate, green, sparse pubescent. Calyx tube to 3mm long, glabrous internally. Lower lip 3-lobed.

Origin - Native to U.S.
Other info. - This species can be found mostly in the southern half of Missouri but it is also present in counties along the Mississippi and Missouri rivers. There are three species of Strophostyles in Missouri and the genus is easy to recognize because of the deflexed and curled keel petals of the corolla. Differentiating between the three species can be difficult at times and the differences in the bracts at the base of the calyx tube seem to be the best way distinguish between these species.

Upper lip single lobed(with two united teeth), acute, to +2.2mm long. Lower lip 3-lobed. Lateral lobes to 3mm long, acute to acuminate. Central lobe to +5mm long, acute to acuminate. Fruit to +8cm long, subterete, sparse appressed pubescent to glabrous, green (dark brown to black when mature), elastically dehiscent.
Flowering - June - October.
Habitat - Thickets, rich woods, moist ground, roadsides, railroads.
Origin - Native to U.S.
Other info. - This is a frequent plant in Missouri. The flowers are easy to recognize because of the twisted keel petals. The leaves of the plant can be somewhat variable. As you may notice, the leaves in the first picture above are quite different from the leaves in the second picture. Some authors break the species apart into two different varieties based on the leaf shape and fruit size but I won't do that here.

S. pulchellum produces much seed and grows easily from seed so it would make a great garden subject. Why isn't everyone growing this plant?

Family - Fabaceae
Stems - Trailing to sprawling, herbaceous, carinate, greenish red, from taproots, dense with retrorse uncinate prickles to +2mm long.
Leaves - Alternate, petiolate, bipinnate, stipulate, to 12cm long. Stipules filiform, to +6mm long. Petiole and rachis with antrorse uncinate prickles. Leaflets opposite, glabrous, ciliate margined, oblique at base, 5-6mm long, 2mm broad, oblong, mucronate, +/-16 pairs per pinna, opposite pairs folding together when touched.
Inflorescence - Axillary globose pedunculate clusters of +/-70 flowers. Flowers sessile or on pedicel to -1mm long. Peduncles to 7cm long, with antrorse uncinate prickles.
Flowers - Corolla tubular, 5-lobed, glabrous. Tube to 3mm long. Lobes 1mm long. Stamens 5-10, well exserted. Filaments pink, to 1.5cm long, glabrous. Anthers yellow, .2mm long. Style 2cm long, pink, glabrous. Ovary cylindric, green, 1.6mm long, striate, tuberculate. Calyx green, minute, .2mm long, glabrous, toothed. Fruit to +10cm long, linear, with prickles, carinate.
Flowering - May - September.
Habitat - Glades, open woods, thickets, prairies, roadsides.
Origin - Native to U.S.
Other info. - Although very attractive and neat to play with, I wouldn't recommend getting too friendly with this plant. The uncinate (hence the name) prickles grab on to most anything and are hesitant to ever let go. Despite the prickles, the plant is eaten by many animals and is very nutritious.
A common synonym is S. nuttallii (DC) Standley

Family - Rosaceae
Stems - To +4m long (tall), erect, climbing or sprawling, woody at least at the base, glabrous to hispid, armed with prickles or not, terete.
Leaves - Alternate, typically 3-foliolate on older growth, 5-foliolate on younger growth. Leaflets elliptic, ovate or oblong, serrate, to +5cm long, 4cm wide, glabrous above, variously pubescent to glabrous below. Petiole and stipules glabrous or glandular pubescent.
Inflorescence - Single flowers or few flowered corymbs from leaf axils.
Flowers - Petals 5, pink (rarely white), to +3cm long. Stamens many. Styles 5, united and protruding from hypanthium. Hypanthium +/-1cm in diameter. Sepals 5, to +1.5cm long, pubescent to glandular pubescent. Flowers fragrant.
Flowering - May - July.
Habitat - Moist ground, thickets, open woods, fence rows, roadsides.
Origin - Native to U.S.
Other info. - This is one of the more common roses found in the state. It seems to prefer a shaded location with neighboring plants for support, but will grow fine in the sun and alone.
The plant is quite variable and Steyermark lists two varieties and five forms of the species, mostly based on leaf pubescence and flower color. I wont go into those here.

Stems - Woody, with dense straight prickles, hirsute, erect to clambering, to +1m tall. Prickles pubescent (at least at base).
Leaves - Alternate, odd-pinnate, with 5-7 leaflets. Stipules to 3cm long, 1cm broad, ciliate and glandular margined, glandular and pubescent below, glabrous above. Leaf rachis with prickles below, densely pubescent. Leaflets elliptic to rotund, crenate-serrate, glandular and pubescent below, glabrous and shiny above, rugose, 5-6cm long, 3-4cm broad.
Inflorescence - Single flowers from upper leaf axils. Peduncles to 1.7cm long, 3mm in diameter, densely glandular pubescent and non-glandular pubescent.
Flowers - Petals 5, rose, 4.5cm broad, 4cm long, free, glabrous, emarginate to obcordate, scented. Stamens very many (+100). Filaments white, glabrous, 6-7mm long. Anthers yellow, 2.1mm long, 1.2mm broad. Sepals 5, alternating with petals, lanceolate, joined at base, densely glandular pubescent below, pubescent above and on margins. Hypanthium subglobose, somewhat flattened, glaucous to moderately covered with prickles. Seeds many, crinite, with a hornlike protrusion.
Flowering - May - September.
Habitat - Cultivated and rarely escaped.
Origin - Native to Asia.
Other info. - I first read about R. rugosa in "This Old House Magazine", Sept./Oct. 1996. It's a great article and talks about the history and uses of the plant. Apparently the plant is quite popular on the island of Nantucket.
Personally, I'm not a huge rose fan, but this plant is nice. Nice to look at perhaps, but don't touch it. The stems are dense with stiff prickles. They may not be hooked prickles, but they can do damage none the less.

Family - Rosaceae
Stems - To +3m tall, multiple, erect to ascending or sprawling, woody below, with many recurved prickles, from a branched taproot and stolons.
Leaves - Alternate, odd-pinnate, with 5-9 leaflets. Leaflets oblong, elliptic or ovate, serrate, to +3cm long, glabrous above, pubescent below. Stipules at base of petiole fimbriate-pectinate. Petioles pubescent.
Inflorescence - Terminal panicles, usually broader than long(tall). Pedicels glandular pubescent.
Flowers - Corolla to -3cm broad, rotate. Petals 5, typically pinkish but frequently all white, distinct, to 1cm long. Stamens many. Hypanthium present, glabrous. Sepals 5, to 1cm long.
Flowering - May - June.
Habitat - Waste ground, thickets, fence rows, roadsides, railroads. Also cultivated.
Origin - Native to Japan.
Other info. - There are many species of Rosa in Missouri. This species is the easiest to identify because of the comblike (fimbriate-pectinate) stipules at the base of the leaf petioles. This is an invasive species which can ruin native habitat if left unchecked. It should not be willingly planted as it spreads very quickly. Birds enjoy the fruits and thus, spread the seeds.

Flowers - Fragrant. Petals 5, pinkish, glabrous, distinct, spreading, to +2.5cm long, +2cm broad at the apex, emarginate to notched at the apex. Stamens many (+50), spreading. Filaments yellow, glabrous, to 8mm long. Anthers yellow, to 3mm long. Carpels many, with yellow stigmas, slightly exserted from the hypanthium, densely pubescent. Sepals 5, reflexed in flower, long-attenuate, with moderate glandular and arachnoid pubescence abaxially, to -2cm long, with moderate white arachnoid pubescence adaxially and on the margins. Hypanthium green (light), with few to many stalked glands.
Flowering - May - June.
Habitat - Open woods, glades, prairies, thickets, clearings, roadsides, railroads.
Origin - Native to U.S.
Other info. - This is a common species found throughout Missouri. The plant is variable in flower size, leaflets shape, and leaf pubescence. It grows well from seed and would make a good garden subject. Although there are approximately 15 species of roses growing wild in Missouri, this species and another, R. setigera Michx., make up the bulk of the native rose flora in the state.

Family - Portulacaceae
Stems - From a taproot, multiple from base, branching, erect to ascending, herbaceous, succulent, terete, to +8cm long, glabrous but with tufts of pilose hairs in the leaf axils. Hairs white, to 3mm long.
Leaves - Alternate, petiolate to subsessile, succulent, terete to slightly compressed, with a bluish-green tint, to -2cm long, acute. Petioles to 2mm long.
Inflorescence - Terminal cluster of 2-6 flowers. Cluster subtended by a whorl of leaves. Flowers sessile, surrounded by dense white pilose hairs.
Flowers - Petals 5, wine-colored, glabrous. Stamens 10, in a ring at the edge of the receptacle. Stigma 5(4)-lobed. Style glabrous. Ovary half inferior. Placentation basal. Sepals 2, greenish or with a purplish tint, acute, entire, broadly ovate to orbicular, +/-2mm long and broad. Fruit a circumsissle capsule.
Flowering - May - October.
Habitat - Glades, rocky bluffs.
Origin - Native to U.S.
Other info. - This striking little plant is found in a handful of counties in western Missouri. Since it is succulent, it survives well on glades where water is scarce. Given good growing conditions, the plant can form fairly large mats. It would do well as a rock garden plant in cultivation.
The flower morphology looks typical but actually isn't. The petals and sepals are not true organs in this genus but are called such to simplify descriptions.
