314 SALMON: SOME SPECIES OF ECTROPOTHECIUM 
Bridel published his species from the single locality, ‘‘ In His- 
paniola unde missam Balbisius habuit et communicavit, in arbori- 
bus habitat.’’ Miller, however, in describing the plant in the 
“Synopsis” does not mention this locality, but gives, apparently 
by a mistake, the habitat ‘“ Portorico: Bertero.’’ For the follow- 
ing reason it seems possible that this mistake arose through some 
error of copying. As mentioned above, there are two labels on 
the sheet of “ Z. ruti/ans”’ in Bridel’s herbarium. On one label is 
written “ Leskia capillaris, ad saxa locis udis Portorico”’ in one 
handwriting, and to this is added, in Bridel’s handwriting, ‘ Balbis 
Lyon 1820.” Over the plant to which this label belongs Miller 
has written ‘‘ Omalia rutilans Brid.’’ It is to be noted, however, 
that Bridel himself has not in any way identified this moss as 
belonging to his ‘“ Z. ruti/ans.”’ An examination of this plant from 
Porto Rico shows that it belongs to a small form of Ectropothectum 
amphibolum Spruce — agreeing exactly with the plant sent out in 
Spruce Musc. Amazon. et And. wo. 1145, from the Andes of 
Peru, and also with examples from Cuba (collected by Liebmann) 
in the Kew Herbarium. It may be questioned, perhaps, if the 
other localities given by Miiller, viz., ‘‘ Venezuela, Cumbre de 
Valenzia, alt. 3,000’: Wagner 1848,” and “ Insula St. Catharina 
Brasiliae, loc. umbrosis pr. Destero, Jan. et Febr. 1847: Pabst” 
really belong to the present species. 
The example named “ £. rutilans’’ by Mitten, in the Kew Her- 
barium, from Rio de Janeiro (comm. A. Glaziou, mo. 7453 
belongs to £. amphibolum Spruce ; the inflorescence is monoicous. 
Since Schwaegrichen’s and Bridel’s names date from the same 
year, we are at liberty to choose either for the present species. 
Schwaegrichen’s name is, however, preferable on every ground, 
both for the reason that a clear description, indicating the inflores- 
cence, together with a good figure, is given of H. vesicu/are, and 
that Bridel included under Z. rutilans a variety “ portoricensts,” 
which proves to be specifically distinct. 
The plant from Rio de Janeiro (collected by Jameson) pub- 
lished in 1824 as a new species under the name of Hookeria prae- 
longa by Walker-Arnott (Mem. Wernerian Nat. Hist. Soc. 5: 
203) was referred to by Wilson (London Jour. Bot. 7 : 278. 1848) 
in a note on “Hypnum scaturigenum Schwaegr.” as follows:
