the first three or four leaves on the new shoots bear thorns in their 
axils, the rest having only a single bud, which develops into a branch 
the following spring, while upon each side of the thorns are the 
supernumerary buds from which two shoots arise. 
Plantago pusilla, Nutt.—This little plant I have noticed more fre- 
quently the past Spring than ever before; by roadsides in sandy soil 
and in grass fields as loamy as any of our lands they grow by the 
thousand—more abundantly, I think, than any other species of the 
genus. I must believe that botanists as well as others have over- 
looked it on account of its minute size. 
Additions to Suffolk Co. Catalogue——Thus far this season, Mr. 
Miller and I have added to our list the following species: Spergula 
subulata, Salix discolor, Menispermum Canadense, Bromus race-

Lately [have come into possession of fine specimens of the Hyp- 
num pseudo-sericeum, C. Maller, mentioned as new from Oregon 
in the January number of the Bulletin, but too incomplete to al- 
low the proper delineation of its characters. The author of the 
species has drawn the following description from fertile specimens 
of great perfection which I was enabled to forward to him.
