from the same Province: Guinatacutan, Bur. Sci. 13188 Foxworthy & 
Ramos, March, 1911, in fruit, a form with narrow lanceolate leaves, and 
Bur. Sci. 13270 Ramos, Kabibihan, March, 1911, with male flowers, referred 
by the late Dr. C. B. Robinson to Securinega acuminatissima. 
I cannot definitely refer this species to any described section of the 
genus Phyllanthus. It resembles Securinega, but its 3 stamens and absence 
of a rudimentary ovary in the male flowers excludes it from that genus; 
it seems to come nearest to the section Gomphidium, but the styles are 
scarcely united, are spreading, and prominently cleft. It is not at all 
closely allied to any species of Phyllanthus familiar to me, and probably 
will have to be made the type of a new section. Its striking characters 
are its 6-merous flowers, 3 stamens with filaments somewhat united, 
anthers erect, free, longitudinally dehiscent, disk present in both sexes, 
ovary 3-celled, styles 3, spreading, slightly united at the base, each cleft 
about half-way to the base.

After a careful examination of a full series of specimens I can see 
no good reason for considering that more than one species is represented 
here. Cuming 1855, the type of Mueller’s species is to me only a rather 
small leaved form of the species later described by Dr. Robinson; this 
form is sufficiently closely matched by some of the recently collected 
material, and all intermediates occur. Additional material: Negros, For.

The Visayan name Anislag appears on several specimens from Leyte and 
on the Sorsogon specimen, the latter with the statement that the timber is 
noted for its durability when used as posts.
