Rocky MountTAIN FLORA 
Lupinus argentinus sp. nov. 
Perennial, densely appressed white-silky throughout: stem 
4-6 dm. high: petioles 5-7 cm. long; stipules lanceolate-subu- 
late; leaflets about 7, oblanceolate, densely silky on both sides, 
3-5 cm. long, conduplicate and with strongly curved back: in- 
florescence rather short and dense; bracts ovate-lanceolate, short, 
deciduous: flowers about 1 cm. long: calyx and pedicels densely 
white-silky, spurred at the base; lower lip lanceolate, about 
one third longer than the upper: corolla bluish-purple; banner 
pubescent on the back, about as long as the wings: pods oblong, 
densely pubescent, about 3 cm. long and 5—6-seeded. 
This species is nearest to ZL. argophyllus, but differs in the denser 
and whiter pubescence, the broader curved leaflets and the more 
pubescent banner. It grows at an altitude of 1200-2200 m.

Bot. Garden); Provo River, 1881, JZ E. Jones, 2169; Salt Lake

Lupinus comatus sp. nov. 
Perennial, somewhat cespitose : stem about 3 dm. high, pubes- 
cent with long spreading silky hairs: petioles of the basal leaves 
about 1 dm. long, also pubescent with spreading hairs, leaflets 
narrowly oblanceolate, acute, 2.5-4 cm. long, green, pubescent on 
both sides ; stem-leaves similar, but with shorter petioles ; stipules 
linear lanceolate, long-acuminate : raceme short and dense, short- 
peduncled ; bracts lanceolate-subulate, equalling or exceeding the 
buds ; pedicels and calyx densely pubescent with spreading hairs ; 
lips almost equal, ovate-lanceolate: flowers 8-10 mm. long: 
corolla bluish-purple, rarely white; banner slightly shorter than 
the broad wings. 
The species is somewhat related to Z. /axtflorus but the calyx 
is not spurred, the raceme short and dense, the flowers larger and 
the pubescence of the stem and petioles long and spreading.

Lupinus maculatus sp. nov. 
Perennial, strict : stem 4-6 dm. high, finely appressed puberu- 
lent: petioles short, 2-4 cm. long, almost glabrous ; leaflets 5-7, 
those of the lower leaves obovate-oblanceolate, mucronate ; those 
of the upper oblanceolate and acute, sparingly appressed hairy 
beneath, glabrous above, 3—5 cm. long: inflorescence short-pedun-
