Flowers hermaphrodite, irregular. Calyx inferior, 5-fid, 5-partite, 
or through the segments being variously connate or deficient, 3- or 
2-partite or spathaceous. Corolla gamopetalous; base shortly or 
slenderly tubular; throat usually broader ; limb spreading, normally 
5-fid, sometimes 4-fid through the two posticous lobes being united or 
the anticous absent; sometimes more or less bilabiate; lobes equal or 
the posticous pair shorter. Stamens 4, didynamous, or reduced to 2, 
inserted on the corolla-tube, exserted or included, alternating with the 
corolla-lobes ; filaments filiform or very slightly thickened at the base ; 
anthers 1I-celled, obliquely basifixed or versatile, dehiscing longitudinally. 
Disc hypogynous, annular, unilateral and glandlike, or inconspicuous. 
Ovary superior, 2-celled or rarely by abortion obliquely 1-celled ; style 
terminal, filiform, simple, acute, obtuse or minutely bifid, stigmatiferous 
at the apex but not or slightly thickened. Ovules solitary, pendulous, 
anatropous. Fruit -small, included within the calyx, indehiscent, 
2-celled, or by abortion 1-celled, or separating into 2 1-seeded nutlets ; 
pericarp slightly fleshy, crustaceous or somewhat woody, rarely mem-

either carpel. Seeds pendulous, usually oblong and terete; testa mem-

perennial herbs, or rarely small annuals. Leaves alternate, fascicled, 
or rarely the lower ones opposite, cauline or rarely radical, entire or 
toothed, often narrow and rigid or coriaceous, Flowers small, solitary

arranged in terminal elongated spikes, corymbose panicles, or sometimes 
lateral towards the ends of the branches. Corolla lilac-purple, white or 
rarely yellow. 
A smal] Order of 9 genera and about 200 species, mostly concentrated in South 
Africa, with a few representatives in Tropical Africa, one in Madagascar; with an outlying 
genus widely dispersed through the north temperate zone, another in the Mediterranean 
region, and a single monotype in Socotra. A species of Dischisma was collected by 
Drummond at the Swan River, W. Australia, where it is reported to be abundant, 
though believed to be only an accidental introduction.
