The middle portion of the filament presents a straight, un- 
broken outline. Rarely a distinct constriction at all the joints of 
a filament occurs. 
The difficulty of distinguishing between Lyngbya and Oscilla- 
Zoria is well illustrated by this species. ‘lhe existence of a sheath 
would naturally lead one to place it in the former genus, but the 
sheath in this case is extremely delicate and observed only ina 
few instances. In Lyngbya there is a distinct sheath containing 
numerous sliding hormogones. 
In general character O. trapezotdea perhaps resembles O. chaly- 
bea Mertens, but is larger, shows no spiral arrangement and is 
clearly distinguished by the shape of the terminating cells of the 
filament. JosEPHINE E. TILDEN.

Botanical Notes. 
Notes from Plum Island and Fisher's Island, N. Y—It may be 
of interest to note the occurrence upon Plum Island and Fisher’s 
Island, N. Y., of a few plants beyond their hitherto recorded range. 
In August, 1892, the writer discovered Juncus dichotomus Ell. * 
gtowing upon Plum Island, and during the past summer found it 
to be not rare upon Fisher’s Island also. 
Ligusticum Scoticum 1. has been known for some years to be 
frequent upon Fisher’s Island; in August, 1895, a station for it was 
found on the north shore of Plum Island. ae 
In 1892 Plantago elongata Pursh (P. pusilla Nutt.) was detected 
growing on the south side of Fisher’s Island. Near the east end 
of the same island is a small colony of Euphorbia glyptosperma — 
Engelm. far out of its cited range. Cuar.es B. Graves.

have lately found this fungus on a dead apple tree in Mr. Bull’s 
orchard, at Mesilla, New Mexico; the specimens have been identi- 
fied by Mr. Ellis. It is new to the U. S. flora. i
