essentially as in Anthoceros, but broader and shorter and still more 
heteromorphous. Like the spores, they are developed in a delicate 
globular utriculus, which contains from one to four of them, and 
which disappears upon their arriving at maturity. They usually 
separate at maturity, but may occasionally be seen adhering to- 
gether, or even closely adhering to the spores. They appear to 
about equal the spores in number, and nearly in size, and are of a 
yellowish brown color, hyaline, much compressed and angular, and 
of a great variety of odd shapes,—usually oblongish but. often 
(when borne singly) nearly or quite as broad aslong. They are 
frequently variously marked (within) by faint lines or fibres, which 
are sometimes reticulated, sometimes spiral and sometimes annular, 
but often irregularly tortuous. The coloring matter is mostly col- 
lected into the fibres and angles, the latter of which are obtusish 
and obscurely thickened. as 
Spores at first in 4s (utriculi matricales seminum quadrispermi !), 
at length mostly separating, roundish, flattish, obscurely angled, 
and nearly smooth. Antheridia very large, composed of large 1n- 
flated convex cellules, usually borne singly in deep pits in the upper 
surface of the frond, which are surrounded by a jagged margin. 
Rootlets smooth or minutely granulose (within). 
17, February Meeting.—At the meeting of the Torrey Botanical Club 
held February 27, 1872, Prof. John Torrey in the chair, Dr. Parry 
laid before the meeting two rare plants from Oregon, collected by 
E. Hall—Coptis aspleniifolia, Salisb., figured in Hooker’s Flora Bo- 
reali-Americana, and a new species of Isopyrum, named Hallit by 
Dr. Gray after the discoverer. This last would be a very desirable 
addition to the garden, being quite ornamental in foliage and 
flower, and an early bloomer. : 
Mr. Leggett presented to the College Herbarium a specimen with 
cone of a new species of pine—Pinus Elliottii, Engelm.—from South 
Carolina, sent by H. W. Ravenel, Esq. co
