REVISION OF TKCTARIA. 413 
3. Tectaria grandifolia (Preril.) Copel. iioiu. nov. 
Aspidiurn, Prosl. E|)iiii. Bot. CA, 18 U); .1. grnndc J. Sin. 1841 (name 
only), Mett. 18oS. 
Except as to the indusiinti, wliicb I'rt'sl, probably in error, rloscrihed 
as orbiculate and peltate, and Mettenius described as real form, the 
diagnoses of A. grande and .1. grandifoJiinti are sufTiciently alike to be 
construed as referring to the same species. Both are based on T*hilipjiine 
plants collected by Cuming, Presl's being from Paiiay. Xo one of Cum- 
t 
ing's plants in Manila is referable here, but MrrrllVs No. 5871 fits 
Mettenius' description very closely and agrees with Presl's wherever it 
differs from Mettenius*. As Presl states, it is a relative of 7\ decurn-na,

A polymorphous species indeed. Cordate, simple, entire ffunds are 
sometimes fertile. The sori arc often elongated along thoir veins, nnd 
the indusia are of various shapes and fugacious. T. irrigiui is not 
sharply distinguished from this species, and the two species succeed in 
it are near relatives. From the material 1 have from the locality from 
which Christ reports A. angulaium, I have no doubt lliat this is the 
plant. Christ is also in error in giving the Joui'iial of Botany 3 as the 
place of publication of the name; A, angulaium J. Sm. was a manuscript 
name first published by Mettenius.

This fern grows on rocks in creek beds and on their banks where it 
is submerged by floods. It is a smaller fern than the preceding and 
much narrower in all its divisions, with comparatively straight margins 
forming sharp bases and apices. T. polymorpha would be torn to pieces 
and destroyed if it grew in the characteristic habitat of 7'. irrigua.
