Tecophilaeceae, E. J. Cowley & R. K. Brummit. Flora Zambesiaca 12:3. 2001

Habit
Glabrous geophytic herbs, perennating from corms or tubers; corms with or without a fibrous tunic of persistent sheathing leaves or leaf remnants (tunic absent in the Flora Zambesiaca area)
General
Caulescent or acaulescent
Leaves
Leaves basal or cauline, spirally arranged, sessile or ± petiolate, sheathing or not at the base, entire, linear or lanceolate to ovate; the outer leaves reduced to ± membranous non-photosynthetic sheaths without blades (cataphylls)
Inflorescences
Inflorescences terminal in acaulescent plants, or lateral on caulescent plants, scapose or pedunculate; flowers in panicles, racemes or spikes, or flowers solitary, usually bracteate, leaves and scape sometimes arising separately from each other on the corm apex
Flowers
Flowers hypogynous, bisexual, trimerous, actinomorphic, pedicellate
Perianth
Perianth segments (tepals) 6, fused into a short tube at the base, or ± free to the base, segments reflexed or not
Androecium
Stamens 6, inserted at the throat of the perianth tube, equal (or in the New World sometimes heteromorphic or some reduced to staminodes); filaments glabrous, short; anthers basifixed, 2-locular, sometimes tailed, connivent at apex or not, dehiscing by an apical pore or clavate slit, or splitting longitudinally
Gynoecium
Style erect, filiform, straight or curved; stigma small, capitate or minutely 3-fid Ovary inferior, semi-superior or superior, 3-locular; placentation axile, ovules 2-many per carpel
Fruits
Capsule 3-lobed, loculicidal; seeds small numerous smooth or warty, or few and large and sometimes with a conspicuous chalazosperm

Tecophilaeaceae, Susan Carter. Flora of Tropical East Africa. 1966

Habit
Perennial herbs with corms or tubers
Leaves
Leaves petiolate, sessile or amplexicaul, linear to ovate-orbicular, decurrent to cordate
Inflorescences
Bracts sometimes minute or absent Inflorescence racemose, pseudo-racemose or paniculate, or the flowers solitary
Flowers
Flowers pedicellate, hermaphrodite, regular or slightly irregular
Perianth
Perianth-segments 6, free or forming a short tube, entire, spreading or reflexed
Androecium
Stamens 6, inserted on the perianth-segments at the throat of the tube, all perfect or 2 or 3 replaced by linear staminodes; anthers dithecous, sometimes connivent, with the base sometimes produced into a spur or sac; dehiscence by an apical pore, usually slightly introrse
Gynoecium
Ovary semi-inferior, rarely almost superior, trilocular; ovules 2–? in each cell; placentation axile; style filiform; stigma minutely trifid
Fruits
Capsule trilobed, dehiscence loculicidal; seeds small and numerous, or a few large ones, rarely only one developing, smooth or warted, rarely with spongy cap; endosperm present

Habit
Herbs with fibrous tunicated corms or thick orbicular flattened tubers
Leaves
Leaves radical or towards the base of the flowering stems, linear to ovate-orbicular and cordate, glabrous
Flowers
Flowers bisexual, actinomorphic, in simple racemes separately from the tuber or corm, or in panicles; bracts large and membranous to small
Perianth
Perianth-tube short or absent; lobes 6, spreading or reflexed, subequal, imbricate Stamens 6, perfect, or 3 and with 3 staminodes, inserted at the throat of the perianth; anthers 2-locular, the connective often produced at both ends, the base then swollen or spur-like, cells opening by a terminal pore, rarely by a slit
Gynoecium
