Herbs, perennial, from corms. Stems simple or branched. Leaves several, sometimes prostrate; blade plane, ensiform to oblong. Inflorescences spicate, spiral or secund, 2-5-flowered[-many-flowered]; bracts pale to light brown, irregularly streaked with dark brown, unequal, outer usually exceeding inner, scarious, acute or 3-cuspidate, inner apex 2-furcate to 2-cuspidate. Flowers odorless [fragrant], actinomorphic [zygomorphic]; perianth tube funnel-shaped, sometimes obliquely so; tepals spreading, connate into tube, variously colored, sometimes with strongly contrasting markings, subequal, outer whorl slightly larger than inner [unequal, dorsal tepal largest]; stamens symmetrically arranged [asymmetrical], unilateral; anthers straight [coiled]; style [unilateral, often arching over filaments] dividing into 3 short branches, apices spatulate [long, filiform]. Capsules globose to oblong, cartilaginous. Seeds 8-15 per locule, globose; seed coat light to dark brown, hard, shiny. x = 10.[50] [more]

Spenceria

Herbs perennial, white villous throughout. Rhizome woody, densely covered with remains of old petioles. Stems erect, terete, simple. Radical leaves: stipules ovate, herbaceous, adnate to petiole; petiole sheathing at base; leaf blade imparipinnate; leaflets opposite, rarely alternate, broadly elliptic or obovate-oblong; cauline leaves few, with few leaflets, or simple and then margin 3-lobed or 2- or 3-serrate. Inflorescences terminal, laxly racemose; bract entire or 3-lobed; involucre close to petals, cupular, 7- or 8-lobed, lobes narrowly ovate to lanceolate. Hypanthium obconic. Sepals 5, valvate, broadly linear to lanceolate, persistent; epicalyx segments 5, semiorbicular or triangular. Petals 5, golden or cream, oblanceolate to obovate. Stamens 30-40, in 2 or 3 series; filaments dilated and connate at base, persistent. Carpels (1 or) 2, at base of hypanthium, apically villous; ovary ovoid-cylindric; ovule 1, pendulous; style subterminal, filiform, long exserted from hypanthium; stigma minute. Fruit composed of flower parts excluding deciduous petals, dry and somewhat hardened. Achene 1, subglobose, with thin coat, enclosed in hypanthium. Seed lacking endosperm; cotyledons subsquare, large.[51] [more]

Strophanthus

Lianas or erect or stolon-bearing shrubs, rarely trees, with latex. Leaves opposite or in whorls of 3. Cymes mostly dichasial, terminal, pedunculate or sessile. Flowers large. Sepals free or connate at base, imbricate or quincuncial, basal glands 5 to many. Corolla funnelform, usually turning darker and dark streaked at anthesis; tube short, throat wide; lobes overlapping and mostly twisted to right, distal portions mostly forming filiform, involute long tails; corona 10-lobed, inserted at base of corolla lobes. Stamens inserted at apex of corolla tube; filaments short; anthers sagittate, connivent, adherent to pistil head, spurred at base; disc absent. Ovaries 2, ± connate at base; ovules numerous in each locule. Style filiform. Follicles 2, divaricate. Seeds numerous, with beaked apical coma.[52] [more]
