also appearsin Europe. Zygodiwm is for the most part a tropical 
genus, and most of its species are widespread in warm regions. 
Our own beautiful species, however, is strictly confined to this divi- 
sion, and occurs but rarely in it, usually in wet, sandy alluvium. 
Of the three Osmund, O. regalis is almost cosmopolitan, O. cin- 
namomea extends trom far norch into the tropical regions ot South 
America, and though wanting in Europe, it reappears in Eastern 
Asia, while 0. Claytoniana is another species common only to the 
Appalachian and the Himalayan region. All three are wanting 
west of the Rocky Mountains. Both of the Botrychia ot this 
group are occasionally found in the northern hemisphere of the 
old world. 
The last four species of this group are rather maritime than Ap- 
palachian. Asplenium marinum is strictly a littoral species, but it 
is somewhat doubt!ul whether it is entitled to a place in our Cata- 
logue. It is said to have been collected upon the coast of New- 
foundland by Kendal more than thirty years ago, but later collect- 
ors have not confirmed it. Woodwardia areolata is limited to the 
marshes of the seaboard States, from Cape Cod southward. Wood- 
wardia Virginica has about the same range, but also appears in 
the regions bordering on the St. Lawrence and the great lakes. 
Our little Schizwa is known only in the cedar swamps of New 
Jersey, at three or four points over a limit of about thirty miles, 
although it is said to have been collected in Newfoundland many 
years ago. Perhaps thorough search in appropriate localities may 
yet prove its range wider than we know. 
IV. Pacrric: extending along the western border of the conti- 
nent at points from Alaska to California, ina few cases appearing 
also in the Rocky mountain region.

One or two additional species occur in California, which will be 
more appropriately considered in the next group. Gymnogramme 
triangularis extends from Vancouver's Island to Southern Califor- 
nia and re-appears in Ecuador, South America. Nutholena New- 
berryi ix only known at present in Southern Calitornia (See But- 
LETIN, Vol. i . p- 12.)  Cheilanthes gracillima has been noted 
from latitude 44 degrees to 35 degrees. Mrs, Lyell must be wrong 
in ascribing it to Missouri. Woodsia scopulina has been seen from 
latitude 49 degrees to Columbia River, and appears also in the 
Rocky Mountains as tar south as latitude 39 deyrees. We as yet 
know too little of the range of most of these species to assign a 
precise limit, : St
