Family - Asclepiadaceae
Stems - To +1m tall, densely pubescent in upper 1/2, sparse pubescent to glabrous below, herbaceous, simple, erect to ascending, from a thick taproot, with milky sap, often reddish in strong sun.
Leaves - Alternate, short-petiolate, dense on stem. Petiole to 7mm long, scabrous. Blade linear-lanceolate, entire, to +13cm long, 1.5cm broad, scabrous on margins and midrib. Margins thickened and often reddish.
Inflorescence - Axillary umbellate cymes with +/-60 flowers. Peduncles dense pubescent. Pedicels hispidulous, to +/-1.5cm long in flower. Cymes subtended by linear bracts to 6mm long. Bracts pubescent.
Flowers - Petals 5, reflexed, to 5mm long, 1.5mm broad, glabrous or very sparse pubescent, greenish white and purplish at apex. Anther head 3mm long(tall), 2.2mm in diameter. Pollinia 1.4mm long. Hoods 2.1mm long, whitish with purple tinge at base, appressed and attached to column for most of length. Carpels 2, 2.1mm long, glabrous. Sepals 5, reflexed, ovate, 2.1mm long, 1.2mm broad, hispidulous externally, glabrous internally, reddish at apex. Follicles fusiform, erect, to +12cm long, +/-1cm in diameter, pubescent. Seeds to 9mm long. Coma whitish, to +3cm long.
Flowering - May - August.
Habitat - Prairies, glades, and pastures.
Origin - Native to U.S.
Other info. - I placed this species in the white flowers section of this site because from a distance the entire inflorescence has a whitish appearance. Close up, however, the flowers have a definite purplish-green tinge. This species is easy to ID in the field because of its stout pubescent stems, many flowered inflorescences, and linear lanceolate leaves (which are alternate). The plant is common throughout most of the state except for apparently some areas of the Ozarks.

All leaflets to +/-5cm long. Involucral leaves petiolate, trifoliolate, much resembling the basal leaves but with a much shorter petiole. Petioles of these leaves with a more distinct adaxial groove.
Inflorescence - Single flower terminating a long peduncle. Often 2-3 or more flowers per plant. Peduncles to +30cm long, sericeous.
Flowers - Petals absent. Sepals petaloid, greenish-white, 5, sericeous abaxially, glabrous adaxially, +1cm long, +5mm broad, acute, with expanded margins near the apex. Margins often involute. Stamens many (+/-100). Filaments glabrous, greenish-white, of varying lengths but the longest to 6mm. Anthers yellow to greenish, 1.5mm long. Carpels many. The ovary ovoid. Receptacle clavate. Individual carpels green, pubescent at the base. Fruit long, cylindric, to 3cm long, +/-1cm in diameter. Achenes green, slightly pubescent in the apical 1/2, densely lanate in basal 1/2.
Flowering - April - August.
Habitat - Rocky and dry open woods and prairies.
Origin - Native to U.S.
Other info. - This species can be found throughout Missouri. The plant is very easy to ID when in flower or fruit because both are distinctive.
Steyermark breaks this species down into three forms, I won't go into those here as they are no longer valid.
Medicinally, this species is an expectorant, an emetic, and an astringent. Natives used the caudex in many forms to cure many ailments. Smoke from roasting seeds was used to revive the unconscious by being blown into the nostrils of the patient.

Family - Vitaceae
Stems - Climbing, with tight, non shredding bark. Pith continuous through nodes. Tendrils present opposite some, but not all, leaves.
Leaves - Alternate, toothed, un-lobed or with two to four small lobes, glabrous, petiolate, truncate to cordate.
Inflorescence - Noticeably broader than long, horizontally branching.
Flowers - Creamy white. Petals separate, small, 2-3mm in length. Fruits globose, 5-7mm in diameter, bluish when mature, glabrous.
Flowering - May - July. Fruits ripening September - November.
Habitat - Wet areas, disturbed sites, low woods, thickets, railroads near woods.
Origin - Native to U.S.
Other info. - THis is a common Missouri species. I have encountered areas where this plant is much more abundant than any of its grape relatives, genus Vitis, and has climbed to the very top of some very tall trees (20-30m). This species does produce a grape-like fruit but it is not edible. The easiest way to distinguish between this species and the true grapes is to notice that the flower clusters of this species are compact and broad. Grapes have clusters which are elongated.
