210 -1//-. Schomburgk's Description of the Mora Tree. 



p/d/ropi.s on the one liaiid, and Leptolohium, and, perhaps, Layia on the other, 

 than between Ovmo.sia as a papilionaceous genus, and BowdicJiio as a Cassiea. 

 At any rate, the name of Scbipirew must be abandoned on account of the iden- 

 tity of the genus Sehipira with Boirdic/iin. 



Mora, as a genus of Ca.ssieœ, is distinguished by the following character : 



Cdli/x urceolato-campanulatus, lircvitcr et late 5-dentatus, cestivatione inibri- 

 cativa. (jtroUa' petala 5, œqualia. Stamina 10, exserta ; quorum .'> pe- 

 talis opposita, fertilia sunt, antheris bilocularibus niedifixis longitudinali- 

 tcr dehiscentibus ; 5 petalis alterna, filiformia, antiieris clavatis cassis. 

 Orarinm brevitcr stipitatum, pluri-ovulatum. Sti/las compressus, sub- 

 rectus, stigmate tenui terminali. Legamen coriaceo-lignosum, oblongum, 

 abortu (an constanter?) monospermuni. Semen magnum, reniforme, 

 cotyledonibus crassis sublignosis, radicula conica recta. 



To the species I should propose tlie name oi Mora e.veelsa ; and to Mr. Schom- 

 Ijiugk's general description of the appearance of the tree I avouIcI add the fol- 

 loM'ing notes taken fiom the dried specimens. No. 496, of his collection.

L'n 1er No. 148 of his collection Mr. Schomburgk has sent specimens from 

 the Upper Essequibo, without any note, which only dilfer from the above by 

 the Howers being smaller, the spikes shorter, the ovarium rather smaller in
