Carex alligata Boott is a member of sub- 
genus Eucarex, Coss. and Germ., section Acu- 
tae Fries, and subsection Cryptocarpae Tuck- 
erman. It stands by itself within the group. 
Relationship of this species with the other 
Cryptocarpae in the islands is close but the 
characters separating them are clear. (See 
Carex kauaiensis, Carex pluvia, and Carex 
pluvia var. koolauensis.) The species seems 
to be an old one in the islands and the stock 
from which it sprang probably gave rise to 
the other two species and varieties. As men- 
tioned before this group is a variable one and 
may be confusing. The young perigynia are 
a light yellow which sometimes turns to a 
very dark brown. This transition may be ob-
