NOETH AMERICAN LOTI. 113 



late : calyx-tube 2 lines long, the superior teetli longer, all 

 softly villous on the margin ; corolla 7 lines long ; pod 1 inch. 

 Northern Mexico ; the original from Zacatecas. Pringle's 

 433 from southwestern Chihuahua answers well to Bentham's 

 description of the species ; and nothing like it has come in 

 from within the borders of the United States. 



16. L. Weightii. Hosaclda WrigMii, Gray, PI. Wright, 

 ii. 42 (1853). Erect, slender, fastigiately branched, a foot 

 high, the growing parts silky-pubescent, at length glabra te : 

 petiole nearly obsolete as in the preceding ; leaflets 3 to 5, 

 linear or oblong, acute : peduncles either extremely short or 

 equalling or surpassing the leaves, 1- to 3-flowered, the bract 

 1-foliolate : calyx-teeth subulate-setaceous, as long as the 

 oblong-campanulate tube : corolla | inch long, yellow or 

 orange, changing to red : pod straight, silky-pubescent. 



Common in open forests of pine, etc., in the mountains of 

 middle or northerly districts of Arizona and New Mexico ; 

 occupying higher altitudes than the other Lofi of the region ; 

 flowering in summer only. 



17. L. MOLLIS. Hosackia piibertda, var. nana, diffusa, 

 magis cinerea, etc., Gray, PL Wright, ii. 42. H. mollis, 

 Greene, Bull. Calif. Acad. 1. 185 (1885). Densely villous 

 with short spreading hairs : stems numerous from a suffru- 

 tescent base, slender, mostly prostrate ; leaves sessile ; leaflets 

 3 to 5, narrowly oblong to linear, acute, crowded on a very 

 short rachis : peduncles erect, slender, an inch or two long, 

 usually bractless, 1- or 2-flowered : calyx-teeth linear-subulate, 

 a little longer than the tube : corolla | inch long, light yellow, 

 drying reddish : pod an inch long or more, straight, velvety- 

 pubescent : seeds orbicular. 



Open grassy places, or gravelly knolls on the plains and 

 among the foothills of the mountains of southern New Mexico, 

 Arizona and northern Mexico. Totally unlike the preceding 

 in pubescence, habit, and in its distribution over the country 

 which they both inhabit. Flowering in March and April.
