Mr. Scuoununck's Description of the Mora Tree. 209 
never inspected the flowers of that tree, or he would have found that, though 
resembling some of the Mimoseæ, it forms one of the Cassieæ of De Candolle. 
The absence of authentie references prevents me from describing it; but I 
hope that this want will be supplied by a more competent botanist before this 
account is laid before the Linnean Society. 
Additional Observations by GH Bentuam, Esq. F.L.S. 
From the specimens transmitted by Mr. Schomburgk, it appears that the 
Mora forms a new genus belonging to the order Leguminosæ, and to the tribe 
Cassieæ of De Candolle. Its nearest affinities are with Tachigalia of Aublet, 
and Leptolobium 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 Vogel, 
connect the Sophoreæ with the Cassiew, a circumstance to which I also ad- 
verted in my memoir, inserted in the Vienna Annalst. Mr. Vogel gives to the 
group the name of Sebipireæ, and considers it as a section of the Cassiec or 
Cesalpinee. He has, however, correctly shown that the direction of the radicle 
cannot be made use of as an absolute character to separate the Sophoreæ from 
the Cassieæ, and the only remaining distinction lies in the papilionaceous co- 
rolla of the former; and this arrangement is certainly more distinct in Bow- 
dichia (the same genus as Sebipira), which he takes as the type of the section 
of Cassie, than in Ormosia; which he leaves among Sophoreæ. It is true, that 
the passage from the perfect papilionaceus corolla of Sophora, 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 Bowdichia, Ormosia, and Di- 
* At the time Vogel published this genus in the Linnæa (vol. xi. p. 388.), my memoir on some genera 
of Leguminose in the Annals of the Vienna Museum was already in print; and I had there established 
a genus of PAaseolee under the same name: but as Mr. Vogel's paper has the priority of publication, 
the name of my genus of PAaseolee may be changed from Leptolobium to Leptocyamus. ; 
+ The Thalesia mentioned on this occasion in ny PN isa genus of Martius, which will probably 
be included in Leptolobium of Vogel.
