4. A.LATERIFLORA L., var. Taylorae n. var., foliis glabris. Cetera 
ut apud var. angustifoliam. 
Resembling var. angustifolia, but having glabrous leaves.— Known 
only from the region of the delta of the Mackenzie River, where it 
was twice collected by Miss Elizabeth Taylor. To her, in recognition 
of her collecting in several high northern regions, the variety is 
dedicated.

zie delta, July 13, 1892, Miss E. Taylor, no. 27; Peel’s River near

In the treatment of this group in the Synoptical Flora ! Dr. Robin- 
son cited one of these two sheets as var. glabrescens. Later Blankin- 
ship included this number in his var. tenuicaulis. Blankinship at 
some time annotated on one of the two sheets, “near var. angusti- 
folia (Regel) 1. c., J. W. B.” It will be seen that this collection has 
been a thorn in the flesh of the students of this group, and in view 
of the characters stated in the foregoing description, the author feels 
justified in describing it as a new variety.
