 scarious sheathing base rigid tip acioular margin thickened minutely 

 ciliate, midrib prominent on both surfaces, floral larger lanceolate-subulate 

 scarious, flowers large sessile, sepals ovate-lanceolate acuminate with 3 close- 

 ^et green nerves in the axis much smaller than the broad obovate petals.

 branches with the leaves about § in. diam. L:'ams \ in., rigid, midrib very strong, 

 brii^ht green, shining. Flowers % in. diam., bracteate by the 2 upper pairs of leaves. 

 Calyx truncate, not thickened at the base ; sepals I in., nerves very strong, approxi- 

 mate. Petals 4 in. long, persistent, white, shortly clawed. Filaments slender. Styles 

 3, slender. Cajpsule apparently never fertilized, small, subglobose, 6-valved. 



10. A., pulvinata, Edgew. ; densely tufted, branches densely leafy, 

 leaves short subulate from a scarious sheathing base semi-cylindric mucro- 

 nate margin not thickened strongly ciliate, midrib usually obsolete, flowers 

 sessile, sepals ovate-lanceolate subacute with 3 close-set nerves in the axis 

 much smsdler than the obovate petals. 



Tibetan region of the Sikkim Himalaya, alt. 1.5-18,000 ft., J. D. H. 



Forming small subglobose densely compacted subsquarrose tufts ; branches with the 

 leaves on ^-j in. diam., pale green. Leaves spreading and recurved, |-|-in., very 

 strongly ciliate, almost fimbriate towards the base, flat above, back convex up to the 

 tip, which is abruptly mucronate. Flowers \ in. diam., not bracteate by the enlarged 

 upper leaves (as in A. monticola). Calyx rounded and thickened at the base ; sepals 

 vith bard scarious margins, about half as large as the petals. Dish-tjlands distinct. 

 Filaments slender. Styles 3, slender. Capsule ovoid, about J in., shorter than the 

 sepals, 6-valved. /Seeds obovate-renilbrm, nearly smooth, pale. 



11. A. oreophila, Hook. f. ; nearly glabrous, densely tufted, stems 

 short densely leafy, leaves spreading and recurved rigid narrowly linear- 

 subulate from a broad sheathing base semi-cylindric acute margins not 

 thickened quite glabrous, midrib obsolete, flowers very shortly pedicelled, 

 sepals nearly orbicular concave nerveless half as long as the narrow 

 obovate-spathulate petals. 



Tibetan region of the Sikkim Himalaya, alt. 18,000 ft., /. D. H. 



Forming small subglobose densely compacted tufts ; branches with the leaves 4— f in. 

 diam. Leaves nearly J in. long, spreading, nearly flat above, convex to the tip be- 

 neath; uppermost pair short, bract-like, ciliolate. Flowers J in. diam., solitary; 

 pedicel shorter than the calyx, stout, puberulous Calyx rounded and somewhat thick- 

 ened at the base ; sepals coriaceous, ciliolate. Petals very narrow, tip rounded. 

 Filaments s'ender. Disk glands prominent. Styles short. Capsvle broadly ovoid, 

 obtuse, rather exceeding the sepals, coriaceous, 6-Talved to the base. Seeds ear- 

 shaped. 



14. A. ^lobiflora, Wall. Cat. 639 ; densely tufted, stems short pubescent 

 densely leafy, leaves spreading subulate-lanceolate pungent from a narrow
