ARCHI-LEJEUNEA. 97 
Obs. The Para plant is the same as that from eastern Peru, and differs 
from that of Guayaquil, at the western foot of the Andes, in the leaf- 
lobule having an incurved tooth at the apex, and mostly an adjacent 
smaller tooth on the upper margin; and in the terminal (or axial) flower 
on the main stem being usually 2, while the end of each branch bears 
a short ¢ spike, beyond the two, three, or more 9 flowers that are set 
along the branch. But many plants of both forms are purely female, 
without any male spike. 
Montagne’s figure of his L. Aubertana in Sagra’s History of Cuba, t. xix. 
f, 3, is not unlike our plant, but the leaves are said to be subrotund.
