148 GLEASON: A NEW GENUS OF RAPATEACEAE 
peduncles, arising in fascicles from one or more of the leaf- 
sheaths and terminating in a subcapitate cluster of bracted 
flowers. Subsequent examination and comparison with the 
material at the New York Botanical Garden demonstrated 
beyond a doubt that the plant was a member of the Rapateaceae 
and that it could not be assigned to any of the seven genera 
hitherto recognized.

Since Schomburgk named a genus, Saxo-Fridericia, and a 
species, Rapatea Friderici-Augusti, in honor of a contemporary 
German ruler, the present generic name Windsorina is given 
in commemoration of the House of Windsor of Great Britain. 
Windsorina guianensis is essentially acaulescent, as are all 
other members of the family, bearing several erect or ascending 
leaves which reach a height of a meter. Of this length, the 
lower fifth or fourth is flattened into a sheath, bearing the 
midvein on one side and not in the center, and about 25 mm. 
wide. At the summit of the sheath, the leaf contracts to 10 
mm. wide, and then expands into the broadly linear, acuminate 
blade, which is 50-75 mm. wide. As in all Rapateaceae, the 
lade bears a peculiar relation to the sheath. The midvein of
