Waziristan: Zam defile in the Suleiman range, 3,500 feet; J. L. Stewart п. 138! 
Wana, 4,500 feet; Duthie’s Collector п. 15788. 
This curious species has all the facies of Osostegia limbata and О. Aucheri, the 
leaves being in shape like those of the latter, but like those of the former in not haing 
pungent tips. The ovary, however, makes its reference to Otostegia or to the adjacent 
genera Roylea or Ballota impossible, while its glabrous anthers exclude it from Lagochilus. 
It is therefore necessary to refer the species to Molucella in spite of the fact that it is 
very unlike the other species of the genus. The calyx of this plant is, though on a 
smaller scale, exactly that of Moiuceila spinosa Linn.; the species is therefore referable 
to § Chasmonia,

Natural order Labiate. 
Rootstock perennial, woody; stems densely softly silky with spreading hairs, simple, 
short, about 8—15 cm. long, rather stout, bluntly angled and distinctly grooved; leaves 
all sessile, small, 1%25--1:5 сш. long, 1—1:25 cm. wide, close-set, thick, ovate-acute, base 
truncate or subcordate entire, margin elsewhere coarsely serrate, softly silky on both 
surfaces; whorls many-flowered, bracts short, linear; calyx 5 mm. long, mouth truncate 
with ten very short erect teeth and these very closely villous but elsewhere glabrous 
within; corolla 7 mm. long, tube not exserted and not annulate. 
UPPER Burma: Popah Hill, 5,000 feet; Collett n. 29. 
This species in externals resembles very closely the densely woolly form of Leucas 
lanata Benth. from the dry hills of the Deccan (L. collina Dalz.) but on closer examin- 
ation is readily distinguished by the calyx which is densely villous within .at the 
mouth only, and not, as in all the forms of L. lanata, sparsely hirsute throughout 
the upper third; the corolla too is very different in showing no trace of an annulus 
within the tube.
