I. Plagiochasma rupestre (Forst.) Steph. 1 Filmore Canyon, Organ Mountains, 
altitude 1800 meters, July 7, 1897, Wooton. This is probably the most inter- 
esting of our known species of Hepaticae, for it is reported in the United States 
only from southern Arizona and this one station in New Mexico. The Organ 
Mountains lie forty miles north of El Paso, Texas, and the Mexican border. 
They are notable for the large number of Mexican species occurring there, as 
well as for their large fern flora. One fern, Phanerophlebia auriculata, a member 
of a characteristically Mexican and Central American genus, is known in New 
Mexico only from this range. Filmore Canyon lies on the west slope of the 
Organs, being a broad, open canyon with beautifully colored porphyritic sides, 
bearing only a sparse vegetation of xerophilous plants. High up in the canyon, 
however, a few pines and Douglas spruces appear, accompanied by other species 
typical of the Transition Zone. If the elevation given upon the label is correct, 
this Plagiochasma was collected near the base of the mountains, amid plants 
characteristic of the Upper Sonoran Zone. 
2. Reboulia hemisphaerica (L.) Raddi. Gilmore’s Ranch, White Mountains, 
altitude 2,250 meters, August 4 and 6, 1897, and August 17, 1908, Wooton. This 
locality is a very interesting one botanically. Considerable collecting has been 
done here, many of the plants of Wooton’s 1897 set, which was widely distrib- 
uted, having been gathered in the immediate vicinity. It is the type station for 
a long list of species of phanerogams. 
3. Conocephalum conicum (L.) Dumort. Collected cwice in the Sandia 
Mountains, east of Albuquerque: Placitas, August 3, 1910, Wooton ; in lime- 
stone soil along a stream, Balsam Park, 1914, Miss Charlotte C. Ellis , 12. 
4. Marchantia polymorpha L. Placitas, Sandia Mountains, August 3. 1910, 
Wooton. In wet soil and along brooks, Brazos Canyon, Rio Arriba County, 
August, 1914, Standley & Bollman, 10701, 10795. In the latter locality this 
conspicuous plant was abundant, growing nearly everywhere along the mossy 
banks of the brooks which flow through the pine and spruce timber. 
5. Chiloscyphus rivularis (Schrad.) Loeske. Ponchuelo Creek, Pecos National 
Foresc, altitude 2,580. meters, in running water, July 30, 1903, Standley. Rio 
Pueblo, Taos County, August 11, 1910, Wooton. On wet soil and in brooks, 
Brazos Canyon, August and September, 1914, Standley & Bollman , 10703, 10793, 
1 1 18 1. Very abundant in the last locality, growing nearly everywhere in suit- 
able situations. 
6. Porella platyphylla (L.) Lindb. Holt’s Ranch, Mogollon Mountains, 
July 20, 1900, Wooton. Gilmore’s Ranch, White Mountains, altitude 2,250 
meters, August 17, 1908, Wooton. Rocky Canyon, Grant County, August 8, 
1911, Holzinger. All these localities are in the southern part of the state. 
7. Frullania Brittoniae Evans? Northward face of a cliff, Brazos Canyon, 
Rio Arriba County, September 4, 1914* Standley & Bollman, 11138. Concerning 
this collection Dr. Evans states, in a letter to Miss Haynes: “The Frullania 
from New Mexico is certainly very close to F. Brittoniae, although the under- 
leaves are not quite typical. I wish very much that the specimen had peri-
