Aspidiutn Whitfordi is probably a form, rather than a good variety; 
characterized by having tlie veins conspicuous on the upper surface; in 
other respects the plants are mostly refcral)le to var. wa< fxlnn. Lu/,<m,

This species as a whole is a very natural one, distinguished from the 
preceding by the color, texture, margins, naked and often irregular sori, 
absence of free included veinlets, and coarse, chocolate-colored scales 
crov,Tiing the rhizome and burying the bases of the stipes. Tt is the type 
of Arcypieris, but is not isolated enough to be given generic rank by itself, 
and is no near relative of our other exindusiate species, T. Bryanti and 
T. amhigua. On the other hand is nearly related to Pleornemia, as is 
shown by the venation, the shape of the sori, the texture and the pubep- 
cence. But for these many points of resemblance I should not include 
Pleoaiemia in Tectaria, 
17. Tectaria feuzeana (Gaud.) Copel. nom. nov. 
Pohjpodivm Gaud. Freyc. Voy. Bot. ;iGl, 1827. 
As distinct as Aspidiu?n angiloyeme Clirist, Bull. Herb, Buiiis, II 6 
(190G) 1003, appears in its description, and as difFercnt as its huge tyjtical 
form is from the more common small forms, T am unable to find any 
constant character distinguishing tliem in the field. Kven the few 
specimens collected by Cawing seen (o mc to have been more safely treated 
as a single species. At any rate, our specimens of No. 33 (F, Cumin- 
giana) and No. 289 {P, leiiceana), of P^pinieliae Bot. p. 50, arc alike. 
However, I am not ready to pass positive judgment on the question. 
T. leuzcana remains a very variable species even if the arJK)re.-<*ent form 
is removed from it. We have T. leuzcana, •«- s., as follows:
