Pacific Coast Alders.—C. C. Parry. (Bull. Cal. Acad... Seri. 1 
Pp. 351-354; reprinted.) 
Dr. Parry gives a general account of the dickens of the Amer- 
ican A/nz, and concludes that A. rhombifolia, Nutt., of the 
Pacific Coast and A. oblongifolia, Torrey, of New Mexico, are but 
- forms of the same species, Nuttall’s name having priority. 
Pharamacognostical Notes.—Joseph Schrenk. (American Drug- 
gist, April 1887.) 
Valeriana, Arnica, Serpentaria, Aconitum Napellus and 
Rhamnus Purshiana are all remarked upon from a pharmacog- 
nostical standpoint. The two characteristic lines or ridges on the 
lower surface of the leaf of Erythrorylon Coca had been de- 
scribed by Hanausek and other authors as “folds” in the blade. 
_ Prof. Schrenk shows, by figuring a cross-section, that these lines 
consist of sub-epidermal strands of collenchyma cells, and sug- 
gests that they might serve as an elastic stiffening to the blade. 
Very curious forms of branched glandular hairs detected on the 
leaf of tobacco are described and figured. Prof. Schrenk found | 
them rather abundantly on very young leaves, but quite sparingly _ 
on commercial tobacco. 
Photograph of Ophioglossacee. 
Mr. George E. Davenport has sent us a beautiful photograph 
of American Ophioglossacee, taken from a set prepared by 
_ him for the Middlesex Institute: He is willing to furnish 
_ copies to botanists at 35 cents each.
