than to any other described species. The banner has the edges

Annual, about 3 dm. high, branched from the base, the 

 branches usually decumbent at base, then erect, yellowish, pu- 

 bescent with short ascending or appressed hairs, sparingly leafy: 

 stipules subulate, about 3 mm. long, pubescent, especially the 

 tips: petioles very slender about 3 cm. long, the uppermost 

 scarcely reduced; leaflets about 6, linear, 2 cm. long, 2-3 mm. 

 wide, the apex merely acutish, the base a little narrowed, pubes- 

 cent with appressed hairs, the bright green upper side less so 

 than the pale under side: peduncle 5 or 6 cm. long, extending

 violet-blue in whorls of about 6: pedicels slender, 5 mm. long, 

 pubescent: calyx densely pubescent with short hairs, the lower 

 lobe 4 mm. long, ovate-lanceolate, entire, acute; upper lobe little 

 more than 2 mm. long, cleft nearly to the base, the divisions 

 parallel and i mm. apart except at the apex, where they are 

 slightly curved toward each other: corollas 7 or 8 mm. long; 

 banner with the edges turned back, meeting only near the apex, 

 open cornucopia-like when viewed from behind, only a little

 across, the face marked with a spot 3 mm. long, 4 mm. wide, at 

 first pale pink with several dark dots at the base, later turning 

 to dull rose; wings shorter than the banner by about 2 mm., 

 broadly inflated, 4 mm. wide at base, and nearly that much at 

 apex, the edges meeting all around except the space covered by 

 tlie lower calyx lobe, the upper edges closely pressed against the 

 face of the banner, except a space 2 mm. long from the apex 

 down, the apex with a very short slightly incurved point; keel
