This species differs from A, unilaterale Lam., the type and probable parent 
of the group, in its size, narrow pinnae with straight inferior margin, and sparse 
sori, in all which respects it is nearer to Japanese than to Philippine or Malayan 
plants of the parent species. Growing with the var. minutum were some larger 
plants with exceedingly thin pinnie shaped more like those of A. unilaterale; 
these were uniformly sterile, and as plants referable to A. unilaterale were also 
near, were very likely hybrids.

This very curious plant bus not before been found south of Formosa.

This is conspicuously distinct in appearance from ordinary L. involuta; but 
some of our specimens of the latter approach it sufficiently so that I do not 
care to try to distinguish it specifically. As in other Philippine specimens of 
L. involuta^ there are free included veinlets. 
Loxo gramme grandis ( Racib. ) Copel. n. comb. ( Gymnogramme grandis 
Recib. in Pteridophyten von Buitenzorg 1898, 72) is most easily distinguished 
from this variety by having a long stipe.

POLYPODIUM L. 
Polypodium millefolium Bl. 
Mount Malindang, 200 m. s. m. Mearns and Hutchinson For. Bur, 4647. 
Java. 
The Malindang plant is deeply tripinnatifid, and the texture is almost coria- 
ceous, but I do not believe it is separable. Small fronds are almost like 
Blume^s figure in Fl. Jav., pi. S8. 
Polypodium Oodes Kze. 
Polypodium Rudimentum Copel. in Perkins' Fragmenta 1905, 190, is this species. 
While Elmer's collection, on which P. Rudimentum was based, was quite uniform, 
Williams' from the same vicinity contains also typical P. Oodes and intermediate 
forms. Mr. Maxon kindly called my attention to this fact, and showed me 
Williams'' plants. 
Polypodium rivulare Copel. Philip. Journ. Sci. I (190G) Suppl. 163 is not 
distinct from P. dolichopterum Copel. I. c. p. 162. I have at hand more than 
one hundred specimens and in so rich a collection the two forms run together.
