Mr. Schomburgk's Descrijifioi/ <if the Mora Tire. 209 



never inspected the flowers of that tree, or lie would have found that, ihoui^h 

 resembling some of the iMimosed', it forms one of the L'u.ssiccc of De C'andolle. 

 The absence of authentic references prevents me from describiui;- it ; but I 

 iiope that this want will be supplied by a more competent botanist before this 

 account is laid before the Linnean Sueietv.

From the specimens transmitted by INIr. Schomburgk, it appears that the 

 Mora forms a new genus belonging to the order Leginui/iosfv, and to the tribe 

 Cassiecr of De Candolle. Its nearest affinities are with Tac/iiga/ia of Aublet, 

 and Leptolohlum of Vogel * ; but it differs from both in the woody texture of the 

 pod, which is, moreover, naturally dehiscent, in the greater regularity of the 

 floral parts, and in the sterility of the alternate stamina. 



The Mora belongs to the series of genera which, as observed by V'ogel, 

 connect the Sophorece with the Cassieœ, a circumstance to wiiich I also ad- 

 verted in my memoir, inserted in the Vienna Annalsf. Mr. Vogel gives to the 

 group the name of Sebipimr, and considers it as a section of the Cassiere or 

 Cœsalpineœ. He bas, however, correctly shown that the direction of the radicle 

 cannot be made use of as an absolute character to separate the Sophorece from 

 the Cassiece, and the only remaining distinction lies in the papilionaceous co- 

 rolla of the former ; and this arrangement is certainly more distinct in Boiv- 

 dic/iia (the same genus as Schipira), which he takes as the type of the section 

 of Cassieœ, than in Orinosia, which he leaves among Sup/ioreœ. It is true, that 

 the passage from the perfect papilionaceus corolla of Sop/iorci, to the regular 

 one of Mora, is gradual ; but it appears to me that the line of distinction 

 would be much more naturally drawn between Boiodicliia, Ormosia, and Di- 



* At the time Vogel published this genus in the Liniuea (vol. xi. p. 388.), my memoir on some geiiciii 

 of Lpguminosœ in the Annals of the Vienna Museum was already in print ; and I had there established 

 a genus of P/iascoleie under the same name : but as Mr. Vogel's paper has the jiriority of pul)iication, 

 the name of my genus of Phaseuletc may be changed from Leptolobhnn to Leptocyumvs. 



t Tlie Thalesia mentioned on this occasion in ray pa])er, is a genus of Murthis, whicli will ] ruba'.lv 

 be included in Lepiolohium of Vogel.
