Macbride and Payson — Plants from Idaho 65 
vicinity of Martin. The species is well-known throughout southern 
Idaho by the Indian name, “ tin-piute.’’ 
LAPPULA CINEREA Piper. Our specimens, no. 3577 ape slide 
rock, Josephus Lakes, Custer Co., at an altitude of 9000 ft. 
the understanding of this species heretofore known only from 
Boise and Salmon River Bluffs at 3000 ft. or less. They are lower 
(2-5 dm.) than the collector’s specimens cited by Piper, Bue other- 
wise represent the species gt tly. 
LappuLa Fremontu (Torr.) Greene. This species is well repre- 
sented by our no. 3214 from Challis, which seems to be the first 
collection from Idaho. Nealon and Machride (Bot. Gaz. 61: 38, 
1916) have restored Torrey’s long cond name and cited 
specimens from Assiniboia, Wyoming, and Uta 
OREOCARYA NUBIGENA Greene. Dr. Hall of the University of 
California has kindly compared fruiting specimens of this imper- 
fectly known species, which we were fortunate to secure from two 
localities, with Californian material in the University Herbarium. 
Dr. Hall writes: “‘ The only specimen we have of O. nubigena in 
good fruit is one collected by Brewer at Sonora Pass. In this the 
nutlets are exactly like those of your specimen except that they are. 
somewhat larger. This is perhaps due to their age. In other char- 
acters your plant is a very good match for the Brewer plant, as well 
as for two other specimens, one of which was presumably collected 
with the type. The uniformity in foliage, pubescence, calyx, and 
general appearance is remarkable. I may add that the nutlets in 
the Chestnut and Drew specimen [the type] are apparently like 
yours but only half grown.’’ This careful comparison by Dr. Hall 
shows that the fruit-character for this species given in the key to 
Oreocarya, Contrib. Gray Herb. xlviii. 24 (1916) should be changed 
slightly to read ‘‘ Nutlets not muriculate but somewhat rugose- 
tuberculate, the elevations low and blunt.” The species is a good 
one and is nearest O. echinoides (as shown by its position in the 
treatment just cited) but it connects very closely the O. glomerata 
group, characterized by more or less rugose nutlets with the next 
group (of which O. caespitosa is typical), characterized by nutlets 
that are never truly rugose. Because of the heretofore obscure 
status of O. nubigena, it seems advisable to cite the following col- 
lections, all in the Gray Herbarium, except those referred to by Dr. 
Hall in letter quoted above; these are indicated by the abbrevia- 
tion, Univ. Cal. Herb. Inano: Silver City, Owyhee Co., June 26,
