(Rydb.), comb. nov. — Leaves more or less pubescent beneath. — 
M. subpubescens Rydb. Bull. Torr. Club xxx. 261 (1903). In the | 
treatment of this genus in Contrib. Gray Herb. xlviii. 10 (1916) 
this plant was retained as a species with the suggestion that per- 
haps it ‘‘ should be regarded as a variety of M. ciliata.’’ Our field 
observations have convinced us that this is indeed the proper dis- 
position as in every case our collections were growing with the 
typical form, and, except for the pubescence on the under surface 
of the leaves, were not distinguishable from it. Since the glabrous 
and pubescent states are now known to grow together it is not sur- 
prising that the type collection of I. subpubescens was mixed (cf. 
Contrib. Gray Herb., 1. c. 11). The following specimens indicate 
a range extension, the variety heretofore having been known only 
from southwestern Montana and northern Wyoming. Number 
3272 has pure white flowers and may be known as forma candida, 
f. nov., corolla alba. —IpaHo: Bear Creek below Parker Mt.,

Dr. Nelson, |. c., based his variety on two characters besides 
color but both of these — the degree of glandulosity and the shape 
of the calyx-lobes — are seen on the examination of a large series 
of specimens to be purely superficial. The name tetonensis may be 
retained, however, to designate a not infrequent white or nearly 
white condition which, when occurring with the typical state, 
presents a wonderful and striking contrast.
