4 Rhodora [JANUARY 
Originally distributed as S. decumbens Greene, but differing from 
that common Rocky Mountain species in the greener foliage, the 
lower cauline more rounded or subtruncate; in the more interrupted 
simpler inflorescence with long-pedicelled and smaller heads; in the 
shorter deep green outer bracts of the involucre; and in the shorter 
ligules. 
SOLIDAGO MULTIRADIATA Ait. var. arctica (DC.), n. comb. S. 
Virgaurea L. u. arctica DC. Prod. v. 339 (1836). 
Typical S. multiradiata Ait. Hort. Kew. iii. 218 (1789), originally 
described from Labrador, is known from Hudson Strait to Newfound- 
land, the Gaspé Peninsula, Quebec, and Kewatin; also in Alaska 
(Cape Nome, ete.) and on Nunivak Island. It has the cauline leaves 
comparatively short and reduced below the inflorescence to small or 
at least not conspicuous bracts. The var. arctica originally described 
by De Candolle from Unalaska and from St. Lawrence Bay (Bering 
Strait), has the leaves much more elongate, the upper usually equalling 
or overtopping the compact inflorescence. This plant has been 
examined from the following stations which indicate that it is the 
more characteristic phase of the species in the Aleutian and adjacent 
Islands. UNaraskKa: without locality (Langsdorff, Mertens, Dall, 
Harrington); Dutch Harbor (Van Dyke, nos. 22, 196); Glacier River 
(Van Dyke, no. 141): PororF Istanps: Shumagin Islands (Harring- 
ton): Berna Srnarr (C. Wright).
