346 APPENDIX TO THE ‘ SPICILEGIA GORGONEA.' 
78 6. Erythrina Senegalensis, DC. An elegant shrub, already found 
on the promontory of Cape Verd, and now in our present collection 
from the islands. — 
19 a. Cesalpinia pulcherrima, Sw. This plant, the beauty of whose 
flowers has spread it throughout the tropical world, must likewise be 
added to cur list. į 
79 6. Guilandina Bonduc, L. A ubiquitous plant, found on the 
burning shores of the tropic in both hemispheres, and which may, perhaps, 
be considered, as has been observed of the Cocoa Palm, as one of the 
few plants which migrates, or has migrated, through the agency of the 
Atlantic and Pacific currents. But I believe that M. Alphonse de 
Candolle has no direct evidence in regard to the migration of this 
plant as he has of the Cocoa. Its seeds are exceedingly hard, and 
probably tenacious of vitality. 
79 c. Cassia fistula, L. This plant, which is a native of the East, 
but cultivated in America, and probably in Africa, has escaped from 
plantations, and become spontaneous in the Cape de Verd islands, as 
elsewhere. 
- 8l a. Cassia Thora, L. This species, common throughout the tro- 
pies, has likewise been sent. 
85 a. Tamarindus Indica, L. This tree, cultivated in Africa and 
America, has, perhaps, become wild in the Cape de Verd islands. 
556. Afzelia . . .. A single specimen, in a very imperfect 
state, being without flowers or fruit, may be referred, not without great 
doubt, to the above African genus. The young branch which has been 
sent is thickish and stout, and slightly covered, as well as the foot- 
stalks of the leaves, with a short upright rusty down. The leaves are 
alternate, abruptly pinnate, with two pair of leaflets. The common 
petiole measures scarcely two inches in length, those of the leaflets 
from two to three lines. The leaflets are lance-shaped, somewhat 
rounded at the base, and tapering to a point at the summit, margi- 
nated, and, at times, slightly faleate ; they are entire, somewhat undu- 
lated, like bay-leaves, at the edges, very coriaceous, with divergent veins 
and numerous strong nervous reticulations both on their upper and 
under surface. They are perfectly smooth and shining, and above of a 
| deep green. The upper pair are about four or five inches long and 
two inches broad, the lower slightly smaller, and somewhat more egg- . 
. shaped. This may, perhaps, be the little-known Pancovia bijuga of
