312 APPENDIX TO THE 'SPICILEGIA GORGONEA. 
exterior or lower alone are perfectly developed, and, intercepting 
probably the nourishment, are the cause of the abortion of the ovaries 
of the upper or interior series: the plant seen by Mr. Brown, in which 
all the flowers were abortive, grew probably in a meagre soil. The length 
of the stamens in our plants is variable, some attaining or even sur- 
passing that of the Gynophore, and others in the same flower remaining 
undeveloped, or more than half as short as that organ. A similar 
abortion (and from a like cause) of the interior flowers is observable 
in many umbelliferous plants, and is the inverse of that which takes 
place in several species of the genus Vidurnum, where the abortion 
from other causes is inverse. 
30. Wissadula rostrata, Benth. Fl. Nigr. p. 229. This plant, which 
is the Abutilon laxiflorum of Guillemin and Perrottet, was inserted 
erroneously in the Spic. Gorg. as Abutilon periplocefolium. 
30 a. Urena obtusata, Guillem. et Per. An addition to the Cape de 
Verd Flora, which is supposed by Mr. Bentham to be scarcely distinct 
from the old Urena lobata of Linnæus. 
SAPINDACER. 
43 a, Cardiospermum microcarpum, H.B.K. This species, confounded 
in the Spic. Gorg. with its prototype C. Halicacabum, L., is found in 
large quantities in our present collection. 
43 6. Paullinia Senegalensis, Juss. Flowering specimens are sent 
of this plant. k 
43 c. Sapindus Senegalensis, Poir, Apparently this species, though 
without flower or fruit. 
43 d. Sapindus Saponaria, Linn. This tree, noted already by 
Brunner as having become wild in the island of Santiago, is sent 
abundantly. 
MELIACE. 
43 e. Trichilia Prieuriana, A. de Juss., Guill. et Perr. Fl. de Seneg. 
t. 80. Of this species, first discovered in Senegal by M. Leprieur, 
and which forms a small tree about fifteen or twenty feet high, several 
specimens occur in our present collection. 
VINIFERZ. 
Of this Order, no representatives of which occurred in any former
