Orver. OPHIOGLOSSACE Ah. 
The Ophioglossacee are now considered an order distinet from Filices, 
distinguished by the erect vernation of the fronds, and by having the 
sporangia formed of the interior tissue of the frond, and not a mere trans- 
formation of surface-hairs, as in true Ferns. The prothallus, green and 
formed above-ground in Filices, is here devoid of chlorophyll and formed 
beneath the surface of the earth. Besides Botrychiwm and Ophioglossum, 
this order contains one other genus, Helminthostachys, represented by a 
single species found in India, Ceylon, the Philippines, ete. 
I. BOTRYCHIUM. Swartz. 
Botrychium Lunaria, L. 
d Creek Valley, Colorado, Dr. Parry, Sept. 1874. This oceurs sparingly from the Rocky 
Mountains of British America to Tabraaer, throughout Europe and Northern Asia, and is reported from 
Australia and Tasmania. 
Botrychium simplex, Hitchcock, var. compositum, Lasch. 
Sterile portion composed of two or three pinnately incised segments.- —_

Mount Lyell, California, in a glacial meadow at 10,000 or 11,000 feet elevation, John Muir. High 
Valley in Yellowstone Park, Dr. Parry. Lake Superior to New England. Northern and Middle Europe. 
The specimens from California are only one or two inches high, and have the sterile portion divided into 
three parts, the middle one. largest, all of them pinnately incised. Those from Yellowstone Park are 
taller, and show grades of transition towards a simpler form. They are all rather stout, and have the 
sterile portion set well towards the base of the common stem. Mr. J. W. Dun’s Botrychium, collected near 
Emigrant Gap, at 5,000 feet elevation, is probably this same thing, but I have not seen his specimens. 
Botrychiun lanceoiatum, Angstrom. 
Frond small, 3-9 inches high, somewhat fleshy; the sterile segment 
closely sessile at the top of a long common stalk, in the smallest forms 
3-lobed, in larger ones broadly triangular, twice pinnatifid, the divisions 
lanceolate, entire, or toothed, all set on at an oblique angle; veins forking 
from a midvein; fertile segment short-stalked, slightly overtopping the 
sterile, 2-3-pinnate—‘“‘ Bot. Notis. (1854) p. 68.” Milde, Filices Europe et
