NATURAL ORDERS. Ill 



lished genera. One of these is Erythrophleum of Afzelias, 

 the Red Water Ti-ee of Sierra Leone ; another species of 

 which genus is the ordeal plant, or Cassa of the natives of 

 Congo. Guilandina Bonduc and Cassia occidentalis, are 

 also in the herbarium ; the former, I believe, is unquestion- 

 ably common to India and America ; whether Cassia 

 occidentalis be really a native of India and equinoctial 

 Africa, in both of which it is now at least naturalized, is 

 perhaps doubtful. 



Among PAPILIONACEiE, which constitute the prin- 

 cipal part of Leguminosse in the collection, there is only 

 one plant with stamina entirely distinct. This decandrous 

 plant forms a genus very different from any yet established, 

 but to which Fodalyria bracteata of Roxburgh^ belongs. 



The genera composing Papilionacese on the banks of the 

 Congo have, upon the whole, a much nearer relation to 

 those of India than of equinoctial America. To this, 

 however, there is one remarkable exception. Por of the 

 only two species of Pterocarpus in the collection, one is 

 hardly to be distinguished from P. Ecastaphyllum, unless 

 by the want of the short acumen existing in the plant of 

 Jamaica. The second agrees entirely with Linnseus's 

 original specimen of P- lunatus from Surinam, and seems 

 to be not uncommon on the west coast of equinoctial 

 Africa ; haviug been observed by Professor Afzelius at 

 Sierra Leone, and probably by Isert in Guinea -f while no 

 species of Pterocarpus related to either of these has 

 hitherto been observed in India. On the other hand 

 Abrus precatorius and Hedysarum trifloriim, both of which 

 occur in the collection, are common to equinoctial Asia 

 and America. 



TEREBINTACE^i, as given by M. de Jussieu, appears 

 to be made up of several orders nearly related to each 

 other, and of certain genera having bat little affinity to 

 any of them. Of this, indeed, the illustrous author of the 

 Genera Plautarum seems to have been aware. He pro- [431
