50 CATALOGUE OF CRYPTOGAMIC PLANTS. 
for the sake of uniformity ;—and, in all cases wherein 1 have come to 
a different conclusion, I have done so with the greatest deference to 
his experience, so much greater than my own: I also wish it to be dis- 
tinctly understood, that I am alone responsible for all the errors or 
oversights that may be found in the descriptions of the species to which 
Mr. Wilson's authority is attached, the names for which I have taken 
as they stood in the list with which he obligingly supplied me. 
The species in these collections have no special localities assigned 
to them, with few exceptions; but they may be understood to be from 
the vicinity of Quito, and the neighbouring voleanie mountain Pichin- 
cha, localities which appear to be most prolific in Crypfogamia ; and 
I perfectly agree with Dr. Taylor in saying, that Professor Jameson is 
“ justly entitled to the gratitude of Bryologists for the trouble he has 
taken to send so many interesting and valuable specimens for their 
admiration." 
l. Harrisonia secunda, var. cirrhifolia.— Hedwigia secunda, Hook. 
Musc. Exot. vol. ii. p. 3. t. 46. Braunia cirrhifolia, ils. MSS.

b. Polytrichum commune, Linn. var. ? 
A few barren stems of this moss have been sent mixed with the 
preceding, and may, perhaps, belong to P. commune. 
3. Polytrichum polysetum, Hook. et Arnott.—P. Jamesoni, Tayl. Loud. 
Journ. Bot. 1848, p. 188. 
I have not been able to find any description of this species, but 
it was so named in Hbm. Taylor and in Mr. Wilson's list. It is 
probably P. oligodus, Kunze, and agrees in habit with P. perichetiale, 
Mont., and P. Simense, Bruch. et Sch.: but differs from both in its 
long cylindrical capsules. P, Jamesoni, Tayl., is certainly the same 
species. = 
4. Barbula Quitoensis, Tayl. Lond. Journ. Bot. 1847, p. 332. 
This species comes near to B. inermis, Mont., judging from the 
figure of that species in Bryol. Europ., the peristome is free two-thirds 
only, and not to the base, as described by Dr. Taylor. 
5. Barbula denticulata, Wils. in schedula; dioica, cæspitosa humilis 
subsimplex, foliis remotis spathulatis acuminatis, costa in mucro- 
nem brevem excurrente, margine e medio ad apicem denticulato, 
textura tenera molli, basi e cellulis elongatis laxis maxime pellu- 
cidis superne minoribus, chlorophyllo fere nullo, theca in:pedun-
