Ehizoma as in Hymenophyllum fiabellatum, b u t less elongated.
There are several forms of tbis F e rn ; °
Var. minus. Has contracted-oblong fronds, with small fructification.
I t is from Ceylon. Smaller fronds.
Y ar. majus. -Broader fronds and larger fructification. From

from 50° to 75°.
I am indebted to Mr. J . Smith, Curator of the Royal Gardens,
