OF ALPINE PLANTS IN THE CAUCASUS. 273 
*CERASTIUM PURPURASCENS, Adams, var. TENUICAULIS, Zrautv. 
This I collected on the north side of the Great Aarat, at 
upwards of 12,000 ft.; I brought the same plant from Murat- 
tapa at 10,400 ft., and met with the typical form flowering on 
Elbruz at 11,300 ft.; I also observed it in a flowerless dwarf 
condition on the north side of Elbruz above 12,000 ft. This free- 
blooming species of Cerastium is a delicate ornament of many 
localities in the Caucasus; it is the prevailing species in many 
places, which it decks with an almost complete white covering in 
its time of flowering. Ruprecht, Fl. Cauc. 235, gives its 
minimum elevation at 5700 ft.; but I have collected the var. 
MICROSPERMA on Schambobell at 5000 ft. 
*CERASTIUM LATIFOLIUM, Linn.,=0. polymorphum, Ruprecht, 
Fl. Cauc. 237, is cited by that author from Azunta at 11,500 ft., 
and is reported from many heights in the Great Caueasus of 
9500-10,000 ft.; he also (/. c. p. 239) cites my station for C. 
purpurascens, from Elbruz, as also applying to this species. 
*CERASTIUM ARARATICUM, Rupr. Information concerning the 
allied species is supplied by Ruprecht, Fl. Cauc. 234, and Bois- 
sier, Fl. Orient. supp. 120. Von Trautvetter determined my 
series, which came from Küp-gól at more than 11,300 ft., from the 
Little Ararat close to the summit 12,800 ft., from Kapudschich 
11,000 ft. (large flowering form), from Bingöl-dagh above 10,000 
ft., and from Aschich-dagh, 9500 ft. 
HERNIARIA CAUCASICA, Rupr. Hitherto only known from the 
eastern regions of the Great Caucasus, and there at the heights 
of 9500-11,500 ft. ; see Ruprecht, Fl. Cauc. p. 241.

SCLERANTHUS ANNUUS, Linn., D. UNCINATUS, Rupr. Fl. Cauc. 
242. Recorded up to 10,350 ft. 
HYPERICUM REPENS, Linn., =H. polygonifolium, Rupr. Fl. 
Cauc. 247, has been found in Daghestan as high as 10,200 ft. 
Of the numerous species of Astragalus in the Caucasian 
herbarium, the following are noted from the alpine districts :— 
ASTRAGALUS DECLINATUS, Willd. This species ascends to 
11,400 ft. on Schah-dagh, and I have also gathered it on Dulty- 
dagh, on Lazal, and other high alpine parts of Daghestan. 
ASTRAGALUS SANGUINOLENTUS, Bieb. On Schah-dagh, almost 
as high as the preceding species.
