Rem.—tIt is impossible to make satisfactory references to 
exsiccatae because of the confusion existing between Hypuum 
ramulosum and H. crispifolium. Generally speaking, those bearing 
the former name are Claopodium Bolanderi, but not invariably so. 
In the set at hand, no. 405 S. & L. Muse. Bor. Am., Ed. 2, is this 
species. Macoun Can. Musc. no. 275, in two sets, is C. créspt- 
Solum.
