Danaca WenpLANDI Reich. f., Bot. Zeitung, 30: 490. 1872. 
(Type from Costa Rica, Wendland.) 
We have seen no specimens of this species, which appears to 
_be known only from its original collection. 
DaNnakEa sp. Pinnae about 30 pairs, 7.5 cm. long, 1.5 cm. 
wide, or the lower slightly smaller, truncate at base, abruptly long- 
acuminate at apex ; veins mainly free with occasional ones forked, 
the intercostal spaces about 11 to 1 cm.; rachis continuously winged 
throughout, the wing 1 mm. wide. 
_ Nicaracua: Chontales, Seemann, 218, K ; a single sterile leaf 
but wholly different from any other species in that extensive col- 
lection. In Biologia Cent. Amer. 3: 697 this plant is referred to 
D. Moritziana with which it has little in common. 
Dana sp. Pinnae 12—12 pairs; veins simple, close, the inter- 
costals about 17 to 1 cm.; rachis winged, the wings broadest just 
below each pair of pinnae and becoming narrower and almost 
wanting just above them. 
Costa Rica: J. J. Cooper, K; two sterile leaves only but with 
characters unlike any known species. Baker (Jour. Bot. 25: 20. 
1887) says of it: “Danaea Moritsiana var. or perhaps a distinct 
species.” It is surely not the former. 
DANAEA oLiGosorA Fourn. said to have been collected in Guad- 
eloupe but apparently never described. Said by Baker (Annals 
Bot. 5: 499) not to differ materially from D. polymorpha. 
The remaining described species of the genus are as follows :
