Family - Bignoniaceae
Stems - Woody, climbing or clambering, multiple from base, forming aerial rootlets. New seasons growth glabrous, green.
Leaves - Opposite, petiolate, odd-pinnate, with +/-11 leaflets. Petiole and rachis glabrous or with a few cilia near the base of the leaflets, with a narrow adaxial groove, green. Leaflets opposite, ovate, acuminate, coarsely and irregularly serrate, glabrous above, sparsely pubescent on veins below, acute to acuminate, to +6cm long, +4cm broad. Leaf tissue abruptly contracted and deccurent on petiolule.
Inflorescence - Terminal corymbs of +/-10 flowers. Pedicels to 1.7cm long, subtended by small linear bracts. Pedicel also often with two small scalelike bracts near middle.
Flowers - Corolla red-orange, orange, or yellow, to +/-7cm long, 2cm in diameter, funnelform, 5-lobed at apex, zygomorphic, glabrous. Lobes suborbicular, to 2.5cm broad, 1.5cm long. Stamens 5 (4 + 1), didynamous, included, adnate at contracted portion of corolla tube. Filaments to +3cm long, glabrous, pale yellow. Anthers tan, 5-6mm long. Small stamen with filament to 1.8cm long. Style 1, 4.8cm long, glabrous, yellow-green. Stigma flattened, spatulate, to 3mm broad. Ovary superior, 8mm long, subterete to weakly 6-angled. Placentation axile. Ovules many, glabrous. Calyx tube to +2cm long, reddish, 5-lobed. Lobes 8mm long, acute, 5-6mm broad at base, glabrous internally and externally. Capsules 2-valved, to +15cm long, beaked, woody. Seeds winged.
Flowering - May - August.
Habitat - Open woods, thickets, fence rows, waste ground, disturbed sites, roadsides, railroads. Also cultivated.
Origin - Native to U.S.
Other info. - This striking species is common throughout Missouri but is actually native to only the Ozark section of the state. This is an easily identified vine because of its opposite, pinnate leaves and big, orange flowers. It can frequently be seen growing along fence rows and in waste places.
C. radicans can be aggressive if unchecked and some people are mildly allergic to the plant.

Family - Rosaceae
Stems - Woody, erect, branching, to -1m tall but typically seen much less. New growth and last seasons twigs olive green, glabrous, with a few (to moderate) straight needle-like thorns.
Leaves - Alternate, odd-pinnate, stipulate. Stipules to +1cm long, entire, acuminate at the apex, with a few piose hairs and distinct red glands on the margins. 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. 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.

Leaves - Alternate, odd-pinnate, to +30cm long. Leaflets opposite (sometimes subopposite), glabrous, ovate to oblong, entire, very short-petiolate, mucronate.
Inflorescence - Drooping axillary racemes of +/-10 flowers, to +10cm long. Peduncles and pedicels hispid.
Flowers - Corolla light pink to rose, papilionaceous, to 2.5cm long. Standard to +2cm broad, 1.7cm tall, with yellow spot in center. Stamens diadelphous, tube to 1.4cm long. Anthers yellow-orange, .7mm long. Ovary tuberculate, becoming hispid in fruit, to 1.3cm long. Style upcurved, 6mm long. Stigma elongated, 3-4mm long. Calyx campanulate, bilabiate, hispid. Upper lip with two lobes. Lobes to 3.5mm long, attenuate. Lower lip 3-lobed. Lobes attenuate, to 5mm long. Fruits densely hispid, to +/-8cm long.
Fruit -
Flowering - May - June.
Habitat - Cultivated and rarely escaped to open woods, slopes, and open thickets.
Origin - Native to the southern U.S.
Other info. - This is a very striking plant not only for the flowers but also for the fruits and twigs. The plant is fairly common in cultivation. It can be identified by its pinkish flowers, bristly twigs, and shrubby habit.

Family - Rosaceae
Stems - A small tree to 10m tall. Trunk to 30cm in diameter. Bark thin (-1cm thick), scaly, narrowly ridged, reddish-brown to brownish-gray. Older twigs with round lenticels, grayish-brown. New season's growth tomentose but quickly becoming glabrate. Previous season's twigs frequently tapering to a point and forming "thorns."
Leaves - Alternate, petiolate, tomentose when new but quickly glabrate. Petioles pilose, to +1.5cm long, frequently with a pair of linear stipules at the base. Stipules to 2mm long. Petioles with an adaxial groove. Blades ovate-lanceolate, crenate to crenate-serrate, green above, lighter below, with a few reddish glands on the midrib adaxially, to +6cm long, +3cm broad, blunt to acute at the apex.
Inflorescence - 1-4 flowers terminating new season's growth. Pedicels to +/-2cm long, sparse to densely pubescent (pilose), green and reddish-green.
Flowers - Petals 5, spreading, pink to white, clawed, 2-2.5cm long total, +/-1cm broad (blade), rounded at the apex. Blade mostly glabrous, claw pilose and with pilose margins. Claw +/-5mm long. Margins of blade slightly erose. Stamens +/-20, well exserted, erect, borne at the apex of the hypanthium. Filaments to +/-1.3cm long, pink to white, glabrous. Anthers yellow to brown, 2mm long. Pollen yellow. Styles 5, borne at the base of the hypanthium, +/-1.3cm long, densely pilose in the basal 1/3, glabrous above, slightly expanded below the stigmas, translucent-white. Stigmas capitate, small. Ovary inferior, 5-carpellate, with 10 ovules. Hypanthium green, glabrous internally and externally, 3-4mm long, campanulate to cupulate, +2mm in diameter. Sepals 5, mostly glabrous and green externally, tomentose internally, subulate, 3-5mm long, to 2mm broad at the base, apiculate.
Flowering - April - May.
Habitat - Lowland and upland woods and thickets of the Crowley Ridge. Also cultivated.
Origin - Native to U.S.
Other info. - This showy species is rare in Missouri and can be found wild in just one county from the bootheel of the state. It is much more common in cultivation and wild in states to the south and east. The plant can be identified by its ovate-lanceolate leaves, glabrous pedicels and hypanthia, whitish-pink flowers, and small fruits.
The fruits of M. angustifolia are eaten by wildlife. Humans use the fruit to make jelly, preserves, and cider. The wood of the plant is hard and tough and is good for making tool handles and small items.
