8 DISTRIBUTION OF THE GENERA. 
Crass II. SYMPHYANTHERE.JE: stamens connivent, each with 2 parallel anther- 
cells introrsely fixed upon a much longer horny connective, usually membranaceous or 
cuspidate at the apex, and terminating below in 2 longer or shorter forks, the pollen- 
cells adhering to the clavuncle of the style, all thus held together in a cone. 
Tribe 11. TABERNÆMONTANEÆ : 2 follicles, ovoid or oblong, often pointed, dehiscing along their 
ventral suture, whose introflexed margins are seminiferous: pericarp thick, fleshy or cori- 
aceous : seeds many, attached or suspended each by a more or less elongated fleshy funicle 
resembling pulp; seeds ovate, dorsally convex and striated, channelled on the ventral face, 
with a callous hilum in the middle, and there affixed to near the end of the funicle, the 
other end of which is suspended from the suture; testa coriaceous : embryo heterotropous, 
in corneous albumen, with foliaceous cotyledons and a superior terete radicle.

Taberna, Codonemma, Geissospermum, 
Tribe 12. Macovetiex : 2 follicles, linear, oblong, or terete, dehiscing along their ventral 
suture, the margins of which are thickened introrsely into a solid resilient placenta, semi- 
nigerous on both sides: seeds many, compressed or cylindrical, oblong, imbricated, sub- 
winged at the extremities with the lateral margins incurved, peltately affixed by a median 
hilum : embryo heterotropous, linear or oblong, in thin albumen, with a superior radicle : 
seeds quite glabrous.

Thyrsanthus, Rhazya, Ellertonia, Dissuraspermum. 
Gonioma, Lepimia, Alstonia, 
C. Seeds anatropous without an apical coma. 
Tribe 13. RossrEz: 2 long follicles dehiscing along their ventral suture, the margins of which 
expand internally into 2 septiform membranaceous placentas bearing many imbricated 
seeds, which are oblong, compressed, suspended from the ventral face, marked by a longi- 
tudinal median hilum ; generally clothed with many long, soft hairs, some extending far 
beyond the summit, which is often prolonged into a slender rostrum, sometimes very long 
and covered plumosely with many fine setaceous hairs, often mistaken for a coma: embryo 
in thin albumen, with a superior radicle. 
Robbia, Chariomma, Rhabdadenia, Urechites, 
Elytropus, Adenium, Laubertia, Epigynum. 
Skytanthus, Eriadenia, 
Tribe 14. OpowraDrNIEx : 2 elongated follicles (or 1 by abortion) dehiscing along their ventral 
suture, the margins of which are invariably expanded into 2 broad septiform placente 
studded extrorsely with numerous nodules in longitudinal series, each supporting a seed : 
seed long, terete, erect, narrow at its two extremities, everywhere bare; embryo terete, in 
albumen, with a basal radicle. 
Odontadenia.
