OF ALPINE PLANTS IN THE CAUCASUS. 287 
I could only trace the plant as occurring in small patches up 
to 12,000 ft. At that altitude the specimens from the Little 
Ararat, collected on 12/24 August, 1871, were only 5 em. [2 in.] 
in height of culm. 
ALOPECURUS GLACIALIS, C. Koch,=A. gracilis, Trautv. Re- 
corded by Ruprecht from Daghestan at 11,000 ft. (Boiss. Fl. 
Orient. v. 489). 
AGROSTIS VULGARIS, With. Recorded by Ruprecht from 
Daghestan at 10,000 ft. (Boiss. Fl. Orient. v. 515); the same 
with A. lazica, Bal. 
CarABROSA BALANSÆ, Boiss. Ruprecht brought this from 
Daghestan at 10,500 ft. (Boiss. Fl. Orient. v. 577). 
CATABROSA FIBROSA, Trautv. I found this species, which 
stands very near the previous one, at Küp-göl at 11,300 ft., 
8/20 August, 1871. 
CATABROSA (COLPODIUM) VERSICOLOR, Stev. Recorded by 
Ruprecht from Daghestan at 10,500 ft. (Boiss. Fl. Orient. v. 579). 
Poa annua, Linn., embraces the wide zone from the sea- 
level to upwards of 10,000 ft.; specimens gathered on Sawalan 
at close upon 11,000 ft. were 10-12 em. [4-5 in.] in height, 
20 June/2 July, 1880. 
Poa pratensis, Linn., in its variety ANGUSTIFOLIA, Trautv., 
ascends above Küp-göl on the Great Ararat, thus more than 
11,000 ft., and there throws up a stem of 20-30 cm. [8-11$ in.] 
in height. 
Poa ALPINA, Linn., I possess from Kasbek at 10,000 ft., 5-7 
em. [2-24 in.] high; Ruprecht found it at similar elevations. 
Poa ATTENUATA, Trin., to which Boissier (Fl. Orient. v. 609) 
unites P. aratica, Trautv., was gathered by me 30 em. [112 in.] 
in height at Küp-göl at fully 11,000 ft., 20-9/21 August, 1871. 
Festuca ovina, Linn., in its subspecies SULCATA, Hack., 
was collected by me on Sawalan at 11,000 ft.,and I also have the 
forms BRUNNESCENS and VIOLACEA, Gaud., which have well- 
developed roots, and are 8-12 em. [31-5 in.] in height. The 
variety Ruprecuru, Boiss. Fl. Orient. v. 619, was reported from
