24 OBSERVATIONS ON HOLL’S LIST. 
the grass, at a trifling elevation above the sea. Some misap- 
prehension has, therefore, occasioned Mr. Holl’s quoting me 
for its occurrence ** on almost all the high mountains." 
* Gymnogramma Totta, Schlecht." is G. Lovei, Hook. et - 
Grev. Ie. Fil. t. 89. Though I have myself quoted the former 
synonym with a mark of doubt in the Cambr. Trans., the iden- 
tity of a Cape with an indigenous Madera species appears, 
prima facie, extremely improbable, and not to be decidedly 
affirmed without an accurate comparison of authentic speci- 
mens of each. The Madera plant grows abundantly in all 
the shady wooded ravines of the Island. 
** Nothlochzena lanuginosa, Desv.," occurs occasionally on 
walls about Funchal and Santa Cruz, on the south coast. 
“Asplenium Trichomanes, Linn.” It can hardly be doubted 
that this is 4. anceps, Soland. et nob. in Cambr. Tr. and of the —

* Asplenium Canariense, Willd., on walls" Tam much ; 
inclined to suspect this is A. /anceolatum, Huds., and not the 
true A. Canariense, which is extremely rare on the south side — — 
of Madera, where Mr. Höll chiefly botanized, though tolerably _ 
plentiful in some of the ravines of the north side. I distinctly 
recollect Mr. Höll directing my attention to A. lanceolatum, 
Huds. (which is not uncommon on wails), as a new species - 
and yet, unless it be this A. Canariense, or, though still less 
probable, ** A. rotundatum, Klfs.," of his List, it is altogether 
omitted. 
Of * A. rotundatum, Klfs., on a wall at Funchal,” and * A 
ebenum, Ait," I can say nothing positively, having no ac- 
quaintance with the former even by description, and: not hav- 
ing met with any plant in Madera beari ing more than a remote 
resemblance to the latter North American species. 
* Asplenium acutum, Bory.” It is very questionable 
whether the Madera plant really differs specifically from the 
European A. Adiantum nigrum, L. It appears to me that 
there are no better reasons for regarding it as more than a 
luxuriant form, or, at most, variety, than in the case of the 
Madera Maiden- Hair (Adiantum Africanum, R. Br. in App:
