Porteria bractescens, 
HAs. Caraccas, South Kee Linden (n. 424). 
I name this new genus in memory of the late Sir Robert Ker 
Porter, long H. B. M. Consul-General at Caraccas, the native 
country of this plant, whence he was accustomed to sen —_ 
psacnre saucer-shaped aaaiene, inclined to one side, and the 
corolla is attached to its disc by one side of the base, the base 
itself doetning a blunt spur or gibbosity. Stamens S ele 
included.—Our specimen is a foot and a half long, and appears 
to be only a portion of a much larger plant.
