a space 4 mm. wide between apices of banner and wings; face of 

 the banner yellowish, 5 mm. long, deeply channeled, edges 

 turned back, somewhat flaring at base where they are about 7 

 mm. apart, 3 mm. at the apex; wings narrowly inflated, 3 mm., 

 the upper edges closed, the lower open for nearly the whole 

 length, exposing the keel, width 6mni. when spread out, broadly 

 rounded from' the middle to the apex; keel strongly curved, 

 glabrous, 3 mm. deep at the middle, the acuminate apex purple. 

 The type, in the herbarium of the Nevada Agricultural 

 Experiment Station, is Heller 1002^, collected May 16, 1910, 

 at Grant's Pass, Josephine county, Oregon. It is not closely r.e- 

 lated to any of the other Albifrondes, no part of the stem being 

 at all woody. However, I have decided to admit it to the group 

 on account of its agreement in pubescence, form of flower and 

 leaf shape. 



Lnpinus aiiiabilis sp. nov. 

 Perennial: stems several from a woody candex, about 5dm. 

 high, purplish and rather smooth looking, but appressed pubes- 

 cent under a lens, moderately leafy: lower petioles long, 15 to 

 17 cm., the upper about half that length; leaflets about 9, ob- 

 long, attenuate at base, narrowed and cuspidate at apex, 5 cm. 

 long, 5 mm. wide, yellow-green and glabrous above, (dull green 

 and appressed pubescent beneath; stipules lanceolate-acuminate, 

 the lowermost 15 mm. long, free for half their length, the upper- 

 most 5 mm. long, nearly free: peduncle 5 or 6 cm. long: inflor- 

 escence 1.5 to 3 dm. long: flowers verticillate, equaling the inter- 

 nodes, rich violet purple: pedicels 5 or 6nim. long, slender, silky 

 sericeous, as i^ also the calyx: bracts ovate, acuminate, 4 mm. 

 long, 2.5 nnn. wide: upper calyx lip 2 mm. long, rounded when 

 spread out, shallovvh- notched; lower lip5inin. long, ovate, acute, 

 entire, with a prominent midvein; bractlet in the sinus a small 

 rounded appendage terminating a rib which extends up from the 

 base of the calyx: corollas 9 mm. long, 6 mm. deep, gibbous at 

 ba.se but hardly spurred, a space of 2 mm. between apices of ban- 

 ner aud wings; face of banner 3 mm. long, rather broad with a 

 broad deep groove, edges somewhat turned back, flaring at base;
