REVISION OF TECTA RI A .

3. Tectaria grandifolia (Presl.) Copel. nom. nov. 
Aspidium , Presl. Epim. Bot. 64, 1849 ; A. grande J. Sm. 1841 (name 
only), Mett. 1858. 
Except as to the indusium, which Presl, probably in error, described 
as orbicnlate and peltate, and Mettenius described as reniform, the 
diagnoses of A. grande and. A. grandifolium are sufficiently alike to be 
construed as referring to the same species. Both are based on Philippine 
plants collected by Cuming, Presl’s being from Panav. Xo one of Cum- 
ing's plants in Manila is referable here, but Merrill’s Xo. 5871 fits 
Mettenius’ description very closely and agrees with Presl’s wherever it 
differs from Mettenius’. As Presl states, it is a relative of T. 'decurrens.

A polymorphous species indeed. Cordate, simple, entire fronds are 
sometimes fertile. The sori are often elongated along their veins, and 
the indusia are of various shapes and fugacious. T. irrigua is not 
sharply distinguished from this species, and the two species succeeding 
it are near relatives. From the material I have from the locality from 
which Christ reports A. angulatum. I have no doubt that this is the 
plant. Christ is also in error in giving the Journal of Botany 3 as the 
place of publication of the name; A. angulatum 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 T. irrigua.
