(P. Llaveana, Schiede and Deppe.) They are very much alike in 
habit, cones and flowers, but differ in the number of leaves; P. 
Parryana has three to five, generally four; P. cembroides, three, 
sometimes two; P. edulis two, and P. monophylla one or two. 
Dr. Engelmann suggests, what seems very reasonable, that they 
are all geographical varieties of one species.

On the Species of the Genus Anychia, Richard. * 
By N. L. BRITTON: 
In the course of my investigation of the flora of New Jersey 
I have been impressed by the difference in appearance and 
habitat of the two well known forms of Anychia—the one spread- 
ing, more or less pubescent, short jointed and small leaved, 
occurring mainly in open places, the other slender, erect, smooth, 
larger leaved and longer jointed, preferring dry woodlands, and 
have now reached the conclusion, after a critical examination of 
many specimens both in the field and the herbarium, that they are 
best regarded as distinct species. Under the generic name 
Queria they were early separated by Nuttall, (Genera, 158, 159,) 
who knew the pubescent, short jointed spreading form as Q. 
Canadensis, and the slender, smooth, erect one as Q. capillacea; 
I have examined a specimen of the latter named by himself. 
DeCandolle (Prodromus, iii., 369,) referring the plants to Mich- 
aux’s genus Awychia, retained the two species as A. dichotoma, 
Michx., and A. capillacea, DC., though expressing some doubt 
as to their distinctness, and was in this followed by Beck (Bot., 
131); this was again maintained by Mr. J. H. Redfield (Bull. 
Torr. Club, vi., 61, 62), and Bentham and Hooker in Genera a 
Plantarum, iii., 17, regard the genus as consisting of two North Cy 
American species. By all other authors, so far as I have been able 
to learn, the two have been considered as conspecific, or, regarding ©
