FIscHERIA martiana. Desne., in De Cand. Prodr. v. 8. p. 601. 
An Asclepiadeous plant, very closely indeed allied to Gonolobus 
velutinus, Schltdl. from Mexico (differing chiefly in the longer leaves 
and longer peduncles and approximate lobes to the base of the 
leaves),—and of which Decaisne says, “ Habitu necnon inflores- 
centia Fischeria :” and on referring to Fischeria it will be seen to 
accord admirably with F. Vartiana, described as a native of the 
island of St. Sebastian, Brazil : the spot where our fine dried speci- 
mens were gathered by the late Mr. Fox, when he was our Minister 
at the Court of Brazil. If, as I believe, I am correct in this re- 
ference, the plant is surely not distinct from Gonolobus, of which 
another nearly allied but not distinct species 1s the Gonolobus 
setosus, Benth. (Pl. Hartweg, n. 1193.) In the stove of the 
Botanic Garden of Kew the plant proves to be a large climber,
