SEXUAL BODIES 
No sexual bodies have been observed in diseased portions of 
coconuts or in pure cultures. The absence of antheridia places 
the fungus at once in the faberi group, according to the classi- 
fication of Rosenbaum. (10) 
TAXONOMY 
In determining the species isolated from coconut bud rot, the 
methods employed by Rosenbaum(10) have been followed. Ac- 
cording to his key, which is given below, the fungus is included 
in the faberi group and is the species Phytophthora fabert Maubl. 
AAA. Faberi group.—Antheridium entirely unknown or its relation to the 
oogonium not yet determined, chlamydospores absent or present. 
P. faberi, P. jatrophae. 
B. Chlamydospores large, mean diameter more than 35 #.
