484 APPENDIX. No. V. 
Waltheria indica L. 1 consider W. americana to be a variety of this sportive 
species, which seems to be common to all equinoctial countries. 
Urena americana L. and U. reticulata Cavan. appear to me not to differ 
specifically ; and the plant from Congo agrees with West India specimens. 
Jussiea erecta L. from Congo, agrees with West India specimens in having 
limear leayes; a specimen, however, from Miller’s herbarium, which has been 
compared, and is said to correspond, with that in the Linnean collection, has 
elliptical leaves. 
Chrysobalanus Icaco L, has its leaves more deeply retuse than any American 
specimens I haye seen, but in this respect it agrees with Catesby’s figure. 
Guilandina Bonduc L. from which G. Bonducella does not appear to differ in 
any respect, is one of the most general plants on the shores of equinoctial 
countries. 
Pterocarpus lunatus L. 1 have compared the plant from Congo with an 
authentic specimen from the Linnean herbarium, the examination of which 
proves that the appearance of ferruginous pubescence in the panicle, noticed in 
Linné’s description, is the consequence of his specimen having been immersed 
im spirits. 
Several of the plants included in the fourth list, I am inclmed to consider 
varieties only of the species to which they are referred ; but I have placed them 
among the more doubtful plants of this list, as their differences seem to be 
permanent, and are such as admit of being expressed. One of these is 
Cardiospermum grandiflorum Sw. of which the specimens from Congo differ 
somewhat in inflorescence from the West India plant. 
Paullinia 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 ail the 
West India specimens I have examined. 
Giseckia pharnaceoides L. from Congo, has nearly linear leaves; but I 
have seen specimens from Keenig 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.
