DISTEIBUTION OF THE GENEEA. 7 



Tribe 6. AspinospERMEiE : 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 tegminiform albumen, extremely compressed, with a terete radicle 

 pointing to the summit or obliquely to the margin, with large, thin, foliaceous, oval 

 cotyledons more or less deeply cordate. 



Aspidosperma, Strempeliopsis, Conopharyngia, Pledaneia. 



Thyroma, 



Tribe 7. Allamande^e : 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. Plttmerie^ : 2 large, divaricated, thick, linear-oblong follicles, opening along their 

 ventral suture, which expands internally into 3 flat septiform placentae : 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. Alyxie^ : 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 conduplicated, 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. Craspidosperme^ : 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, Manothrix, Tayotum, Rheitrophyllum.
