It will probably be found that some other Mexican species of Pithe- 
cocteniwm enumerated by De Candolle, especially those with purple 
flowers and a 3-fid cirrhus, belong to this genus. It is not unlikely 
that Mr. Weir's specimen (No. 266), sent without flowers, may be 
another species allied to Phadranthus extatus. This I infer from its 
3-fid cirrhus.

sub-4-gonis, profunde striatis, fuscis, ad nodos valde compressis

axillis utrinque binis et oppositis; racemis terminalibus aut

San Paólo, Brasilia (Weir, No. 152). 
This plant at a superficial view might be mistaken for the Bignonia 
fallax, Cham, (Pharseophora), but a short examination will show the 
difference. It has a dark fuscous appearance, the internodes are 
33 inches apart; the petioles are 24 to 34 inches, the lateral petiolules 
1 line, the terminal one 8 lines long; the leaflets 2 to 24 inches long, 
11 to 13 lines broad, the terminal one being somewhat larger; the stipu- 
loid leaflets, 4 in each node, are 4 lines long and 2 lines broad. The 
main peduncle of the raceme is 34 inches long, compressed, gradually 
widens upwards towards each joint of the insertion of the pedicels, 
which аге 1} inch apart; the pedicel is 1 inch long, bibracteated below 
the middle, and at its base, the calyx, deeply cleft and somewhat 9-la- 
biate, is 1 inch long; the tube of the corolla 12 inch long, segments of 
border 4 to 6 lines long, tube contracted within the calyx, and from 
this point the filaments arise, arching towards each other in pairs, the 
longer pair extending beyond the middle of the tube, with a short
