BOTANICAL OBSERVATIONS ON THE AZORES, 191 
PTEROCLADIA CAPILLACEA, Bornet & Thur? 
Flores (1411). Terceira (1412). Sta. Maria 
' (1412, a). 
A considerable number of specimens was collected. No cysto- 
carps, however, were present and the determination of sterile 
plants must be necessarily somewhat uncertain in this case. 
GELIDIUM FILICINUM, Bory ? 
Terceira (1413). 
A small sterile specimen of what may be this species was col- 
lected. Iam indebted to Dr. Ed. Bornet for an authentic specimen 
of G. filicinum with which the present plant agrees in general habit, 
but, in the absence of fruit, the determination must remain 
uncertain.
