Obs. At Baiios, at the foot of Tunguragua, I gathered a form beset with 
a thick coating of adventitious ramuli, arising either from the leaves or 
(rarely) from the branches. They bear leaves redticed almost. entirely to 
the basal sac, beyond which the lobe projects as a small triangular denti- 
form limb.—The flagelliform branches of the normal state bear small 
pellucid ovate acute leaves almost or quite destitute of basal sac.
