Perennial : stem 8-10 dm. high, glabrous or sparingly strigose 
above, leafy ;. stipules narrowly lanceolate, attenuate : petioles 3-5 
cm. long ; leaflets about 7, spatulate or broadly oblanceolate, about 
4 cm. long, mucronate, those of the lower leaves obtuse, those of 
the upper more acute, glabrous above, finely puberulent beneath ; 
raceme elongated, about 2 dm. long, many-flowered : flowers sub- 
verticillate ; pedicels about .5 cm. long, as well as the calyx, 
pubescent with short spreading hairs ; bracts lanceolate, attenuate, 
deciduous, longer than the buds ; calyx gibbous at the base; lower 
lip lanceolate, about twice as long as the short ovate upper one = 
corolla dark blue, with lighter keel ; banner glabrous, rounded and 
shorter than the wings. 
This has been confused with Z. parviflorus, which it closely 
resembles, differing mostly in the shape of the calyx; the lower 
lip in that species is only slightly longer than the upper and the 
banner is larger and less rounded. The type grew at an altitude 
of 2400 m.

Lupinus flavescens sp. nov. 
Perennial : stem about 3 dm. high, appressed pubescent with 
rather long hairs : stipules lanceolate, densely hairy: petioles often 
°ver I dm. long, appressed silky ; leaflets about 7, oblanceolate, 
3-4 cm. long, appressed silky on both sides: inflorescence short; 
Tracts lanceolate, early deciduous ; pedicels 8-10 mm. long, as 
Well as the calyx densely pubescent with short, spreading hairs: 
calyx gibbous at the base ; its lips almost equal in length, both 
about 8 mm. long: corolla 12-14 mm. long, pale yellow; banner 
| with a darker spot, glabrous. 
The type has been known as Z. sulphureus and was included 
€rein questionably by Watson; but differs in the larger, paler 
flowers, and the longer lips of the calyx, and the longer pubes- 
cence.
