near the recently described S. er Pilger, but this has 
ovate-lanceolate leaves narrowed at base, linear-subulate floral 
leaves, and corollas with the upper lip much euat than the lower. 
EPILOBIUM COLLINUM Gwmet. 
By C. E. Saumon, F.L.S. 
Tus willow-herb was first recognized by C. C. Gmelin in his 
Flora Badensis, iv. 265 (1826), and described as follows :—‘‘ Caule 
erecto, tereti, foliis alternis, subsessilibus, ovato-lanceolatis obtusis 
dentatis, stigmate quadrifido.”” A more detailed description ¢ of re 
specific value follows, and then the interesting note iffert

oribus minoribus, et angustioribus. Loco natali collino, sicco,

It is a plant that occurs in many parts of Kurope in dry, open, 
more or ia rocky places, ascending to some height; and I wish to 
bring this species to the notice of British (more especially Scottish) 
botanists from the fact that the Holmesdale Natural History Club’s 
Museum at Reigate contains two sheets of EK. collinum labelled 
Epilobium roseum? To be examined. Scotland. Dr. Power.”

It may be helpful re botanists unfamiliar with this species = 
give here a few more of the characteristics of E. collinum to supple 
ment Gmelin’s diagnosis. 
E, collinum evidently holds a middle place between montanum 
and lanceolatum, some botanists (Koch, Cosson, etc.) calling it @ 
variety of the former, — Haussknecht, Rouy, Coste, and others 
give it good specific ran 
n his Monograph ae E ipilobium, pp. re 36 (1884), Haussknecht 
digit veinhas the three species as follows :—
