Victoria, where it was discovered by Miss M. Henley. It springs
from a large caterpillar, and differs from all known species in the
sharply differentiated fertile branches being erumpent from a simple,
vertical stroma, eight to nine inches high ; also in peculiarities of the
ascophore. It will be known as Cordyceps Henleyae^ and will be
described in detail at a later date. G. MASSEE, Kew.

ABSOBFTIOK OF WATEB BY DBAD BOOTS.— Several

experiments have already been made relative to the power of dead
roots to supply nourishment to plants \ leading to the conclusion that
if the roots are killed without being ruptured, they may continue
to take up moisture, and thus keep the plants alive for a considerable
time. The matter may be roughly tested by killing the roots of the
plants by immersing them for a time in boiling water, and carefully
noting the results.

The following plants were experimented upon, with the result which
any cultivator would have anticipated, namely, that dead roots are
inci^ble of affording any continual sustenance to the plants to which
they are attached. At the same time it is interesting to observe that
in many cases the plants remained fresh for several days afler their
roots were killed. In every case care was taken to prevent the heat
or steam from the boiling water from injuring the leaves or stems of
the plants above the ' collar.' For the purpose of comparison the
tops of two plants of Cassia alaia were cut off level with the soil, and
placed in water in the same house with those treated with boiling
water. It will be seen that specimen 3, which had been severed
under water remained fresh as long as the plant with boiled roots.

Cassia alata. — i. Plant in pot : roots immersed in boiling water on
Feb. 1 6th, 1893; had not suffered on 20th; flagged on 23rd; leaves
turned brown on 25th, and finally died.

New Ferns of 1892-3.

BY

J. G. BAKER, F.R.S.,

Keeper of the Herbarium^ Royal Gardens, Kew.

THE following are a number of new Ferns and Sela-
ginellaceae which have been received at Kew from
various sources during the last two years. The novelties sent
home from Borneo by the Bishop of Sarawak and Singapore
have been published in the Kew Bulletin, those obtained
upon Kina-balu by Dr. Haveland were included in Dr. Stapf 's
paper read a short time ago before the Linnean Society,
and the new species obtained in the Island of Grenada
by Mr. R. V. Sherring have already been described in the
Annals^. All the present species belong to genera already
known, and do not furnish any striking peculiarity in structure
which has not been already noted. The numbers which
precede the names indicate their position in the sequence
followed in our Synopsis Filicum, and for the two Selaginellas
in my Handbook of the Fern-allies.

CYATHEACEAE.

toideis tripinnatiiidis modice firmis, utrinque viridibus, facie
