Notholaena neglecta Maxon

452—-Notholceaa cretacea,' Liebmann; (N. Californica, D.-C; ,|
Eaton; N. Candida, Hit., var. aretacea, Davenport.)
The very fine series of forms of Notholwna Candida, Hook,* ?
from Texas, recently collected by ReyerfJto», have quite con-
vinced me that; this fern, which has heretofore been referred to
that species, should be recognized as. distinct. That it is Lieb*;
mann’s plant I cannot doubt. Mr. Baker assures me that; ite |
agrees perfectly with Liebmann’s type in the Kew Herbarium» .
and an examination of a pinna from a Kew specimen sent to me
by him, satisfies me that such is the case. It moreover -Agrees;
with Lfebmanii’s original,description # quite as * well as , mosJfc.
specimens do agree with fhfeir descriptions, which are often, neces-
sarily drawn up from imperfect material without sufficient allow* ,
ance for natural variations within specific limits.
Our California plant differs from the Mexican only in having
brown stipites and rachises instead of black, a difference of hardly
more than varietal significance, if even that, and characteristic of
other species in this genus, notably in N. nivea, where the stipites
and rachises vary from dull chestnut brown to glossy black.
Sometimes in Californian plants the upper surfaces of the segments
appear to be more copiously; sprinkled with powdery glands, but
as I have only seen a few Mexican specimens, while several hun-
dred California plants in all conditions of growth have passed
through my hands, I cannot say to what extent this excess may
gq>. The glands are clearly deciduous in-both ìcàses, and in an
equal number of Mexican specimens it is probable that sòme
w£uld-*be found as thickly coated as any from California. g v

Remarks.—The above description apparently calls for a taller plant than is rep-
resented by Mr. Pringle’s, and most of the California specimens, but some of the lattes
in my possession come very near to the dimensions given, and the description given
by Profi Eaton in the Bulletin for May, 1873, from Mettenius,»recognises some very
much less.-—G. E-. D.
