58 MISSOURI BOTANICAL GARDEN, 
Of this and the preceding species, fully developed leaves 
are not yet known; both bloom when the leaves begin to 
unfold. 
16. L. serpyllifolia, spec. nov. 
Upright shrub; branches slender, with light grayish- 
brown fibrous and shredding bark; branchlets nearly glab- 
rous except two longitudinal rows of short hairs. Leaves 
obovate to oblong-obovate, 6-12 mm. long and 2.5-4.5 mm. 
broad, obtuse or acutish, gradually narrowed toward the 
base into a short petiole, about 1.5 long, ciliate and spar- 
ingly appressed-pilose above, glabrous and glaucous be- 
neath. Flowers in pairs on glabrous, slender and drooping 
peduncles 9-12 mm. long, in the axils of the lower leaves ; 
bracts ovate or ovate-lanceolate, acuminate, glabrous, as 
long as or slightly longer than the ovaries; bractlets none; 
ovaries wholly connate, about 2 mm. high, glabrous, 2- 
celled, occasionally 3-celled with one cell smaller and one- 
ovuled; calyx truncate; corolla tubular-funnel-form, 10 
mm. long, apparently yellowish-white flushed with pink, 
ventricose at the base, glabrous without, hairy within 
below the insertion of the stamens; limb with 5 orbicular- 
ovate lobes about 1.5 mm. long; filaments glabrous, inserted 
somewhat above the middle of the tube, twice as long as 
the linear-oblong anthers; anthers partly exceeding the 
limb; style exceeding the stamens, with a few scattered 
hairs at the base; fruit unknown.

Plate 1. f. 1-5. 
Allied to Z. tnconspicua and the two following species, 
but differing from all by the partly exserted anthers and 
the broader bracts, and besides from L. inconspicua by the 
glabrous corolla and the glabrous under side of the leaves, 
from LL. Szechuanica by its pubescence and from L. 
Tangutica by its much smaller foliage.
