This fine species is distinguished from L. pygmwa especially, With which it was formerly in part 
confused, by the insertion of its appendages, the insertion-ceil being unmodified and small, and finally 
continuous with the series of cells which form the primary inner append; the I i | of which an in 
contact with cell V of the receptacle, except the uppermost (innermost).

Since the original publication of this species, it has been possible to examine a considerable amount 
of additional material occurring on species of Phemjuoplms from both bemispher i. The material Inn.. 
these sources is, in general, rather clearly distinguished, however; that from the we ten hen. phen 
adhering closely to the type as originally described, in which the outer appendage is at most not mo* 
than five or six times proliferous, that is the main axis consist of not more than five or six cells and is 
of compact habit: the inner appendage producing, as a rule, only a single branch with two or tin ■ pro- 
liferations, the axis thus only two- to three-celled; a small short stout solitary antheridilim ben- borne 
on a short stalk-cell at its base. Material from the Eastern Hemisphere, though often cioaely resembling 
the type, especially in the African specimens, tends to vary to the condition shown m figure the outer 
appendage, as well as the two branches of the inner, being much more luxuriantly develoj d Eld t 
antheridia (fig. 9) produced usually in groups of two or thn , their form more slender and elongate, the 
necks curved. This is especially true of specimens from Madag; ear, < ylon, the Philippines, and 
localities to the cast of Africa. The differences, however, are not sufficiently absolute to warrant ev< n 
a varietal designation.
