After much talk and tribulation, Monsieur Cardot has dropped the Paris 
code of 1867, with the priority of the subgeneric name, and adopted the Vienna 
Code of 1905, and the “Belgian Decision” of 1910, hence the following changes 
are made: 
1. Pireella Cardot Rev. Bryol. 40 : 17. 1913. 
Pirea Cardot Bull. Soc. roy. Bot. Belg. 32 : 176. 1893. Not Durand 
1888. 
Fifteen species are recognized: P. cavifolia (Card. & Herz.) ; cubensis Card. & 
Ther. ined.; cymbifolia (Sulk); denticulata Card. & Ther. ined.; Fendleri (C. M.);, 
filicina (Sw. [Why Hedw. ex Sw.]?); guatemalensis (Broth.) ined.; Husnotiana 
(Besch.); Mariae (Card.); pachyclada (R. & C.); panamensis (Broth & Par.) 
ined.; papillosula (R. & C.); Pohlii (Schwgr.); Tonduzii (R. & C.); trichomanoides 
(Spruce), and among these four are still undescribed. 
2. Rhacopilopsis Ren. & Card. Rev. Bryol. 27 : 47. 1900. 
Dimorphella (C. M.) R. & C. Bull Soc. Roy. bot. Belg. 41 : 101. 1902-3. 
Hypnum section Dimorphella C. Mull. Flora 69 : 523. 1886. 
Quite recently Rhacopilopsis Pechueli (C. M.) Cardot has been discovered 
in French Guiana, collected by and sent to us by Monsieur Theriot. The species 
had heretofore been known only from Africa. 
3. Diplostichum Mont. Ann. Sc. Nat. 14 : 116. 1845. 
Phyllogonium Section Eustichia Brid. Bryol. Univ. 2 : 674. 1827. 
Eustichia C. Mull. Syn. 1 : 41. 1849. 
The following names are transferred, though their specific value is said to 
be doubtful: D. Brotheri (Besch.); distichum (Schwgr.); longirostre (“Broth.”) 
which should be D. longirostre Mont., the type species of the genus. 
4. Harpophyllum Spruce Cat. Mosses 11. 1867. 
Hemiragis Besch. FI. bryol. Ant. fr. 68. 1876. 
Leskea Section Hemiragis Brid. Bryol. Univ. 2 : 334. 1827. 
There is but one species of the genus known in North America: H. aureum 
(Lam.) Spruce ranging at higher elevations in the West Indies from Jamaica 
and Porto Rico to Trinidad, also in Costa Rica and Guatemala, and the Andes 
of Quito and Bogota. Hemiragis Friedrichsthaliana Reicht., known so far only 
from Guatemala, 1 and the type of which I have seen, agrees exactly with the 
former, and so widens the distribution of the former to include also Central 
America. There appears to be also an undescribed species in Jamaica which 
we have called H. subulatum ms. and which differs from H. aurem in being green, 
not glossy; stems more slender; leaves more secund, less serrate, with short, 
porose cells. 
5. Mittenothamnium Hennings, Hedwigia 41 : 225. 1902. 
Microthamnium Mitt. J. L. Soc. 12 : 503. 1869 not Microthamnium 
Nageli in Kutzing Spec. Alg. 352. 1849. 
Hypnum sect. Stereohypnum Hpe. Linn. 31 : 529. 1861-62. 
Hypnum sect. Rhizohypnum Hpe. Flora 45 : 457. 1862. 
1 C. M. Bull. Herb. Boiss. 5 : 208. 1897.
