484 APPENDIX. No. V. 



Waltherla i?idica L. I consider IF. americana to be a variety of this sportive 

 species, -which seems to be common to all equinoctial countries. 



UreJia americana L. and U. reticulata Cavan. appear to me not to differ 

 specifiealljf ; and the plant from Congo agrees « ith West India specimens. 



Jussicea erecta L . from Congo, agrees with West India specimens in having 

 linear leaves ; a specimen, however, from Miller's herbaiium, which has been 

 compared, and is said to correspond, mth that in the Linnean collection, has 

 elliptical leaves. 



Chrysobalanus Icaco L. has its leaves more deeply retuse than any American 

 specimens I have seen, but in tills respect it agrees -nith Catesbv's figure. 



Gmlandina Bonduc L. from which G. Bonducella does not appear to diifer in 

 any respect, is one of the most general plants on the shores of equinoctial 

 countries. 



Pterocarpus lunatus L. I have compared the plant from Congo with an 

 authentic specimen from the Linnean herbarium, the examination of which 

 proves that the appeaiance of ferruginous pubescence in the panicle, noticed in 

 Linne's description, is the consequence of his specimen ha%'ing been immersed 

 ill spirits. 



Several of the plailts included in the fourth list, I am inclined to consider 

 varieties only of tlie species to wliich they are referred ; but I have placed them 

 ajnong the more doubtful plants of this list, as their differences seem to be 

 jiermanent, and are such as admit of being expressed. One of these is 



Cardiospermmn grandrflorum Sw. of which the specimens from Congo differ 

 somewhat in inflorescence from the West India plant. 



Pmdlinia pinnata L. is distinguished rather remarkably from the American 

 plant by the figure of the leaflets, which approach to cuneiform, or widen 

 upwards, but I can perceive no other difference. 



Pterocarpus Ecastophyllum L. differs merely in the want of the very short 

 acumen or narrow apex of the leaf, which I have constantly found in all the 

 W^est India specimens I have examined. 



Giseckia pharnaccoides L. from Congo, has nearly linear leaves; but I 

 have seen specimens from Kccnig with leaves of an intermediate form. 



I shall conclude this essay, already extended considerably beyond my 

 original plan, with a general statement of the proportion of new genera and 

 species contained in Professor's Smith's herbarium.
