Closely allied to #! fragrans Nees; but that has the smaller frond 
less broadly margined, less thickened in the middle, areole not so 
distinct, scales much longer and scarious at the apex, female 
receptacle only 3 or 4 fruited, perianth more ovate, spores yellow 
and with a thicker jagged coat, &c. 
§ 37. Climbing plants.— Last year there was brought to the Club 
meeting by Mr. J. B. Hyatt, of Morrisania, a microscopic slide con- 
taining a nicely prepared section of a stem of Rhus Toxicodendron. 
showing the pith all on one side, like a hole bored near the edge 
of acoin. If the stem of this plant be examined this will be found 
to be the rule, the thickening being on the under side on that by 
which the plant clings to its support by the aid of rootlets. The 
same appearance may be seen in stems of Ampelopsis, but not of 
Tecoma, nor perhaps in Hedera. Mr. Darwin, (Journal of Linn, 
Soc., Vol. IX, 1867) in his paper on climbing plants, notices the 
thickening of the tendrils and leaf stalks of plants that climb by 
their means, but does not, we believe, account for, and perhaps had 
not seen, the extraordinary one-sided growth of Rhus. It would 
seem that this thickening showed that the plant was nourished by 
the rootlets imbedded in the bark of the tree, but this is mere con- 
jecture. Rhus Toxicodendron seems to prefer the Red Cedar, 
Locust, and Cherry and to shun the Pine. Can any one give us an 
account of its proclivities to other trees ? ieee 
§ 38. Mycotheca Universalis——By Baron de Thiumen, Bay- 
reuth, Bavaria. a : 
Two centuries are already issued, each containing 100 species of 
Fungi represented by dried specimens. Century III will be issued 
in November and willcontain some of the South African Fungi. It 
is intended to include species from all parts of the world. Century 
L, which has come to hand, contains European species with some 
from the United States. Among the species in Century I. may be 
noted the following, viz.: | 
Trametes Pini, Fr., which appears to be rare in this country. Two 
spece., were found, however, at Newfield, N. J.,on dead trunks of
