SCHOMBURGK’S GUIANA PLANTS. 39 
2. Vernonia (Vanillosma,) opaca (n. sp.) ; ramis teretibus 
petiolisque fulvo-tomentosis, foliis oblongo-ellipticis acumi- 
natis basi angustatis integerrimis coriaceis supra glabris 
subtus fulvo-tomentosis, capitulis glomeratis sessilibus axil- 
laribus petiolo brevioribus pluri (8—10) floris, achzenio trigono 
glabro, pappis setis suabeequalibus.—Serra Mey, Schomburgk, 
n. 1016.—This species resembles in habit V. splendens, Less. 
DC. Prodr. V. p. 18, (Gardner's No. 59, and in several 
other Rio collections); but the leaves are not shining above, 
and are longer, and the heads of flowers and pappus are 
different. It is evidently near V. axillaris, Less. (DC., 
l. c. p. 19), but there are certainly no short external setze to 
the pappus. It differs from F. isotrichia, (DC. l. c. p. 18), 
chiefly in the number of flowers in each head. The plant I 
have received from Martius, (with the No. 199 of his Herba- 
rium Flore Brasiliensis, where (p. 126) that number is given 
to V. isotrichia,) has, it is true, as many as fifteen or twenty 
flowers to the head ; but this plant differs, in so many respects, 
from De Candolle's character, especially in the pedicellate 
heads, which bring it near V. umbellata, that I p there 
was some mistake in the distributing of this number. —
