 a woody perennial base : stems erect, sparingly branched, 3^ to 5 dm. 

 high, covered with a spreading hirsute pubescence : leaves sessile, ob- 

 long or oblong-ovate, acute, entire, tuberculate-hispid above, with a 

 scattered substrigose pubescence beneath (somewhat more dense upon the 

 veins), 4 to 8^ cm. long, 1^ to 2|- cm. broad : flowers axillary, disposed in 

 leafy one-sided racemes or scorpoid cymes, in fruit about 15 cm. in length : 

 pedicels 4 to 8 mm. long: calyx deeply 5-parted, persistent; divisions 

 linear, 1-nerved, hirsute-pubescent, 10 to 14 mm. long: corolla tubular, 

 5-lobed, gibbous at the throat, about 3 cm. long ; tube pubescent on the 

 outer surface, inner surface glabrous except along five lines in continuance 

 with the short filaments ; lobes erect, subreniform, 3 mm. long, 5 mm.

 altitude 3,000 m., 18 August, 1896, no. 6451. A species with the habit 

 of L. Palmeri^ Wats., but readily distinguished by the pubescence of the 

 stem and by the characters of the corolla and stigma.
