DISTRIBUTION OF THE GENERA. 7 
Tribe 6. AspiposrrrmE2x : 2 follicles, rarely combined into a 2-locular fruit, or generally only 
1 by abortion, oblong or semi-oblong, compressed or quite flat, subligneous or coriaceous, 
without pulp, dehiscing along the marginal ventral suture into two gaping semivalves 
conjoined along the dorsal margin, with a narrow placenta on the suture: seeds large, 
parallelly adjacent, extremely compressed, broadly winged all round a central embryo- 
niferous scutcheon, which has a small hilum in its centre on the side averse from its 
corresponding valve ; or the scutcheon is truncated at one end, broadly winged at the other, 
or exalate ; each suspended at the hilum by a slender funicle, either vertically from the 
summit, or horizontally emanating from the lateral margin of the suture: embryo filling 
the scutcheon, in a thin :egminiform albumen, extremely compressed, with a terete radicle 
pointing to the summii o obliquely to the margin, with large, thin, foliaceous, oval 
cotyledons more or less deeply cordate. 
Aspidosperma, Strempeliopsis, Conopharyngia, Plectaneia. 
Thyroma, 
Tribe 7. ALLAMANDE&: a single orbicular subcompressed, dry capsule, unilocular, with a thin 
pericarp, densely and coarsely echinated, furnished within the peripherial margin with a 
placentiferous replum, and divisible into two hemispherical valves, smooth inside; seeds not 
very numerous, suspended from the replum in two single series by filiform funicles; testa 
oval, with a broad thick callous margin (instead of a wing) surrounding a flat embryoniferous 
scutcheon, in the middle of which, on one face, is a central hilum, from which it is suspended 
as in Aspidosperma: embryo in thin tegminiform albumen, with a superior terete radicle 
and oval foliaceous cotyledons. 
Allamanda. 
Tribe 8. Prumerira : 2 large, divaricated, thick, linear-oblong follicles, opening along their 
ventral suture, which expands internally into 2 flat septiform placentz: seeds many, sub- 
compressed, furnished below with a lacerated wing, and affixed peltately and imbricatively 
upon each semiseptum : embryo in corneous albumen, with foliaceous cotyledons and an 
inferior radicle. 
Plumeria, Cameraria. 
Tribe 9. Atyxtez: 2 lomentaceous flat indehiscent follicles, transversely articulated into several 
dry, monospermous cells, with a longitudinal placenta projecting along one of the internal 
faces, round which the seeds are longitudinally conduplieated, and peltately affixed by a 
central hilum on the ventral face: embryo in corneous albumen, with oval or oblong folia- 
ceous cotyledons, and superior (or inferior?) radicle. 
Alyxia, Condylocarpon. 
Tribe 10. CrasPIDOSPERMEA : an elongated subcompressed, 2-locular capsule, resolvable into 
2 follicles by the splitting of its bilamellar dissepiment, whose edges are inflected at the 
axis, and there placentiform, bearing many imbricated seeds peltately attached by a central 
hilum on one face, oblong, much compressed, covered all over by numerous long hairs or 
scales, often extending far beyond the apex or beyond the margins, or sometimes lacerately 
winged : embryo in albumen, with a superior radicle. 
Craspidospermum, Manothriz, Tayotum, Rheitrophyllum.
