West Tibet, alpine region, frequent, alt. 13-17,000 ft. ; Nubba, Zanbkae, Piti, 

 Paeang, Ladak, &e. 



Densely tufted, the whole plant 3-4 in. high. Leaves |-1 in. long ; leaflets close, 

 except the lowest, oblong or oblanceolate-oblong, ^— | long, thick, densely persistentLy- 

 matted with white silky hairs on both sides ; stipules minute, deltoid, silky. Flowers 

 20-40, in very dense heads ; pedicels scarcely any ; bracts minute, linear, white- plu- 

 mose. Cah/x ^{ in., densely white-silky ; teeth nearly or quite as long as the tube. 

 Corolla not more than half as long again as the calyx, usually all yellow, rarely pur- 

 ple or the keel tipped with purple ; standard oblong-spathulate, exceeding the wings 

 and keel. Pod much inflated, membranous, sessile, J-f in. long, 5-6-seed6d, shaggy 

 with loose dense white silky hairs. 



7. O. cadiemirica, Camb. in Jacquem. Voy. Bot. 38, t. 44 ; stem, 

 short, leaflets 13-21 oblong-lanceolate densely white-silky, heads dense long- 

 peduncled, bracts distinct lanceolate, pod sessile inflated round-oblong uni- 

 locular. 



West Tibet and Kashmik, temperate zone, alt. 8-10,000 ft. — Disteib. Central 

 Siberia. 



Whole plant J-1 ft. high. SteTns ascending from a woody rootstock, finely pubes- 

 cent. Leaves 1-2 in. long ; leaflets |-J in. long, clothed on both sides with loose 

 white silky hairs ; stipules lanceolate or deltoid, connate downwards. Flowers 1 2-30 

 in a dense head ; pedicels yery short. Calyx f in. long, densely white-silky ; teeth 

 linear, nearly or quite as long as the tube. Corolla half as long again as the calyx. 

 Po(i just like that of the last but rather larger. 



8. O. ItXeinsliausenii, Sehrenh; Led. Fl. Ross. i. 786; stem distinct, 

 leaflets 17-31 thin large oblong green pubescent, beads dense long-peduncled, 

 bracts conspicuous, pod short-stalied oblong unilocular. Bunge Bel. Lehm. 76. 



West Himaiayas, temperate region; valley of Kishengunga, alt. 9-11,000 ft., 

 Stewart. — Disteib. Siberia. 



SteTns a foot or more high, at first thinly pilose. Leaves 3-4 in. long ; leaflets 

 ^-f in. long, obtuse, thinly clothed with rather long whitish hairs on both sides ; sti- 

 pules |— J free, lanceolate or oblong. Flowers 12-20 in a dense head; peduncles erect, 

 4-6 in. long ; pedicels ^j-jj'"' ! bracts linear, ^\ in. long, ciliated with black hairs. 

 Calt/x f in., tubular, thinly clothed with adpressed black hairs ; teeth linear, half as 

 long as the tube, black-plumose. Corolla twice as long as the calyx. Pod oblong, 

 turgid, |-| in. long, straight, 6-8-seeded, with a few dark silky hairs. 



Dr. Hooker procured from Nipalese Tibet flower-heads of a fifth yellow-flowered 

 species which, as far as the material goes, matches the Siberian 0. argentata, Led. It 

 differs from 0. Memshausenii by larger bracts, longer calyx with linear teeth as long 

 as the tube, corolla shorter in proportion, not more than half as long again as the 

 calyx. These two represent in the Himalayas the group of 0. campestris. 



Sect. 2. VerticUlares, DC. Herbaceous perennials ■with flowers in 

 dense heads, with leaflets often in pairs from the same point, so that they are 

 wborled when the nodes are opposite on the two sides of the leaf-rachis.

 cHliophylla, Royle III. 198 ; Camb. in Jacquem. Voy. Bot. 38, t. 45. 



West Himalayas, alpine region, alt. 11-16,000 ft.; Zanskab, Piti, Sassab, 

 Ntibba, Kunawae, &c. ; Sikxim, Hooh. fil. 



Stemless, erect, J-| ft. high, the tufts densely esespitose at the top of a woody 

 rootstock, the deltoid imbricated stipules clothed with dense tufts of long white 

 silky hairs. Xeq/' short-petioled, lJ-3 in. long; leaflets crowded, linear-oblong, ^-^ in. 

 long, subcoriaceous, grey-green, gland-dotted, with fine deciduous pubescence, the edges 

 much refiexed. Pedimcles equalling or overtopping the leaves ; flowers 4— IS, the heads
