Family - Crassulaceae Stems - To 30cm tall (long), erect to ascending (with age), succulent, pink, glabrous, glaucous, multiple from base, simple below, widely branching in the inflorescence, terete, 2-4mm in diameter.
Leaves - Alternate, sessile, terete, succulent, +2cm long, glabrous, glaucous, with two pointed basal auricles. The auricles small, -2mm long. Leaves in the inflorescence reduced to bracts.
Inflorescence - Secund racemes of flowers terminating the main stem, to 6cm long. Flowers sessile. Flowers - Petals 4, pink, to 6mm long, glabrous, linear to linear-lanceolate, acuminate. Stamens +/-8, exserted, erect. Filaments pinkish, glabrous, longer than the petals. Anthers brown when fresh, quickly turning black, +/-1mm long. Ovary 4-5-parted, glabrous. Pistils acuminate. Sepals 4, 2-3mm long, lanceolate, glabrous, greenish-pink, rounded at the apex.
Flowering - May - July. Habitat - Limestone glades, ledges, outcrops, also on chert and sandstone. Origin - Native to U.S. Other info. - This brilliant little plant can be found mainly in the southwest 1/4 of Missouri but is scattered in a few more southern counties also. The plant is an annual but is quite prolific under the right conditions. It likes full hot sun and well drained soils. 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.

Family - Rosaceae 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.

Rachis of leaf with a few pilose hairs or glabrous. Leaflets typically 5. Lateral leaflets sessile, terminal leaflet stalked. All leaflets ovate to oblong-lanceolate, serrate, to +/-4cm long, +/-2cm broad, deep green and glabrous adaxially, light green and mostly glabrous abaxially but with a few hairs on the midrib or villous.
Inflorescence - Terminal single flower on new seasons growth. Pedicel to +/-1cm long, with a few stalked glands. 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.

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.

Family - Portulacaceae Stems - To 30cm tall, herbaceous, succulent, glabrous, erect to sprawling, rarely rooting at nodes. Leaves - Alternate, terete to somewhat flattened, linear-oblong, to 5mm wide, 1.3cm long, succulent. Tufts of stiff bristles present at base of leaves.
Inflorescence - Single flower terminating stem, often with involucre-like whorl of leaves at base of flower. Flowers - Corolla red, rose, pink, orange, yellow or white. Petals to 3cm long, 5 to +30 in number. Stamens +/-40. Flowering - July - September.
Habitat - Cultivated and possibly escaped to dry waste ground of roadsides and railroads. Origin - Native to Argentina. Other info. - This little plant is a survivor. I have friends back in Florida that frequently chop the plant up into tiny bits and then spread the pieces along a brick sidewalk. Within days there are new plants coming up everywhere. This is something to keep in mind if you are thinking of planting the plant in your yard.
The flowers are very striking and new colors are always being developed in cultivation. This species is a "bread and butter" plant of local garden centers. The plant is capable of growing in dry neglected conditions.
