Cardiogyne. | CXXIIIc. MORACE (Rendle). 25 
much as 5 in. in diameter; it yields a colouring matter somewhat resembling 
fustic (Kirk l.c.). 
Occurs also in South Africa (Delagoa Bay). 
4. DORSTENIA, Linn. ; Benth. et Hook. f. Gen. Pl. iii. 366. 
Flowers moneecious, densely crowded on the surface of a more or 
less flattened stalked receptacle. Perianths very short, more or less 
connate, forming a fleshy layer covering the surface of the receptacle 
and leaving pits in which the unisexual flowers are buried. Male: 
Perianth bluntly 2-3-lobed. Stamens 1-3; filaments free, inflexed 
in the bud. Ovary generally absent, sometimes rudimentary. Female 
pits much deeper than the male, terminating in a projecting entire 
narrow mouth. Ovary completely buried; style lateral, projecting 
through the mouth of the perianth above which it is more or less 
deeply 2-fid, simple in section Kosaria. Ovule pendulous. Fruit 
subglobose, with a thin somewhat fleshy exocarp, and a crustaceous 
smooth or warted endocarp, which is ejected elastically when ripe by 
splitting and contraction of the exocarp or remains embedded in 
the receptacle. Seed with a thin testa; albumen absent; cotyle- 
dons contortuplicate——Generally low-growing herbs, sometimes 
shrubby below, with ascending or erect leafy stems growing from a 
slender perennial rhizome which in some species is thick and tuber- 
like; stem sometimes fleshy or much thickened, with leaves at the 
lower nodes reduced to scales; occasionally stemless, with long- 
stalked leaves springing from a thick tuber ; rarely shrubs. Leaves 
petioled, rarely subsessile, alternate, entire or with an irregularly 
toothed margin, rarely lobed, often more or less acuminate; stipules 
lateral, narrow, generally caducous, sometimes persistent. Inflores- 
cence solitary, rarely two or three together and then unequally 
developed, on a reduced or suppressed lateral shoot borne in the 
upper leaf-axils. Peduncle generally much shorter than the leaves 
except in acaulescent species where it is elongated and may exceed 
the leaves. Receptacle flattened, or shallowly saucer-shaped, or 
becoming convex below, or sometimes turbinate, of very various 
outlines, suborbicular, stellate, oblong, rhomboid, or angular, and 
bearing few or many marginal bracts which vary in length from 
small teeth to long arms (a few small bracts rarely present on the 
sides of the receptacle), or several to many times longer than broad, 
in which case the two terminal bracts are much longer than the 
lateral or the lateral are absent ; rarely ebracteate. 
Species about 150, numerous in Tropical Africa and Tropical America, with 
a few in Madagascar, Socotra and Arabia, and 1 in India. 
A. Style dividing into two longer or shorter arms.
