Family - Fabaceae Stems - Vining, trailing or climbing, somewhat woody, villous to hirsute.
Leaves - Alternate, trifoliolate, long-petiolate. Leaflets ovate, orbicular, or rhombic, entire or lobed, pubescent below, glabrous above, to 15cm long. Petiolule of middle leaflet much longer than those of lateral leaflets, all are pubescent (villous).
Inflorescence - Indeterminate, axillary raceme to +20cm long. Flowers - Papilionaceous. Corolla blue-purple on outer surface, reddish-purple on interior. Standard with yellow splotch at base. Fruits compressed, oblong to linear-oblong, to +7cm long, +1cm broad, villous, the hairs reddish.
Flowering - August - October. Habitat - Borders of wooded areas. Origin - Native to Asia. Other info. - Kudzu is one of the most famous weed pests in the south. The vines can cover entire wooded areas killing or stunting all the vegetation below with shade. The species was originally brought to the U.S. as ground cover and fodder and now much research time is being devoted to its eradication.

Flowers - Corolla broad campanulate, 1.1cm broad, pubescent externally, 5-lobed, purplish-blue. Lobes obtuse, purplish internally with deep purple spots surrounded by white at base, lilac externally. Stamens 5, exserted, erect, alternating with corolla lobes, adnate at base of corolla tube. Filaments to 5mm long, pilose. Anthers purple, 2mm long, .9mm broad. Style 1.5-2mm long, mostly glabrous but with a few hairs at base. Stigma 2-lobed. Lobes 1.5mm long. Ovary hirsute(at least at apex), superior. Placentation parietal. Calyx lobes 5, spreading, hirsute, oblong, +/-2mm broad, +5mm long, subequal to unequal.
Flowering - April - June. Habitat - Rocky fields and prairies, moist soils of valleys, glades, bluffs, open woods, roadsides. Origin - Native to U.S. Other info. - This little plant is easy to overlook as it grows amongst some taller grasses and broadleafs. The flowers wilt very quickly in hot sun. The pictures above were taken early in the morning, hence the dew on the plants.
The plant shown above is form hirsuta, which has the typical blue flowers. Form albiflora Palmer and Steyermark has white flowers and is rare. This species can be found in basically the lower 1/4 of Missouri except the southeastern corner of the state.

Lobes spreading, linear, 5-6mm long, 1mm broad, (in flower), glandular pubescent. Fruit subglobose, densely villous and glandular pubescence, 4-valved.
Flowering - April - June. Habitat - Rich rocky woods, moist slopes, rocky streambanks. Origin - Native to U.S. Other info. - This fine species can be found in the east-central portions of Missouri. Despite its small flowers, the plant is still striking because of its mottled, purplish leaves. It should be cultivated more and grows readily from seed.

Family - Passifloraceae Stems - Vinning, glabrous to minutely pubescent, herbaceous. Tendrils present. Leaves - Alternate, 3-lobed, serrulate, petiolate, to +15cm long, +13cm wide, glabrous. Petioles with two glands near base of leaf blade.
Inflorescence - Single pedicillate flowers from leaf axils. Flowers - Very interesting. This flower exhibits a corona which is a structure of appendages situated between the corolla and stamens. In the picture the corona is the ringlike structure of purple and white appendages above the petals and sepals. Flower is typically 6-7cm broad. Petals 5, sepals 5, purplish to whitish, similar, alternating. Styles 3. Stamens typically 5. Sepals 5, greenish-white, with a terminal appendage.
Fruit - Fleshy, ovoid to globose, green at first, yellowish-red at maturity. Flowering - June - September. Habitat - Thickets, disturbed sites, waste ground, roadsides, railroads. Also cultivated. Origin - Native to U.S. Other info. - This plant and its relatives have an edible fruit often seen in drinks as "Passion fruit". Some folks like it, some don't. In his particular species the mucilage around the seeds of the fruit is quite sweet and delicious.
The genus name comes from the story of Jesus in Christianity, the "Passion". The flower parts are telling of the story. The petals and sepals are representative of the disciples of Jesus, except for Judas and Peter. The stamens, numbering 5, represent the wounds of Jesus. The stigmas, because of their shape, represent the nails used in the crucifixion. The corona represents the crown of thorns.
