GRIGGS: SPECIES OF HELICONIA 661 
toward night when we were hurrying to reach our destination, 
and a part of this specimen was lost, so that it is better to pass it 
till another time when fuller material can be had. It was of the 
subgenus Svexochlamys, perhaps closest to H/. cannoidea Rich., 
1.5 m. tall, with seven leaves, 40 cm. long, not quite 10 cm. 
broad, sessile with long acute bases, acuminate at the tip; green 
and glabrous on both sides; peduncle a little less than 10 cm. 
long ; inflorescence bright scarlet, about the same shade as in //. 
tortuosa, rachis deflexed, flexuose, lowest bract 17 cm. long with 
a small blade at the end, next 9 cm., both about 2 cm. broad (0, 
693).
