Alpine fields of Geranium pasterns with scattered Rhododendron patches near the Latpar Pass, with the greater part of the main Caucasian Range in view; Shkara is on the right, and Tetnuld on the left.

Beyond Ushkul is the superb glaciated ridge of Shkara in the Mam Range, and the conical, ice-capped peak of Tetnuld, the " Jungfrau" of the Caucasus One returns to Kal for the night, although at Ushkul there is shelter with a caretaker, but without accommodation. From Kal the journey out of Upper Svanetia begins. Happy is the traveller who has good weather, for the trip is one of great splendour. On leaving Kal the trail mounts through a deciduous forest of Acer trautvetteri, Fagus orientalis, Quercus hartwissiana and Prunus padus. In these woods the foUowmg mosses were collected: Drepanocladus uncinatus Pogonatum alpinum Pogonatum umigerum Dicranoweisia crispula Polytrichum juniperinum P. alpinum At the edge of the forest one finds Colpodium variegatum, Alopecurus nagratus, Cerastium purpurascens, Anemor^ aurea, Inula ghndulosa and Daphne mezereum (with longer and more delicate leaves than D^ glomeraia) Crocus suwarowianus is first met with on emerging from the forest. It is distinguished from its close relative Crocus flavus by its colour, the latter Sa rich orange and the former a light yellow. 0. flavus is abundan m all alpTmeadows from Elbrus to the Latpar Pass. Cohk^cuM autumnale also "?^; approach to the Latpar Pass takes one through extensive alpine fields No high ^ass precedes them. On leaving the deciduous fores one soon comes upon large areas of RModendron cau^si^urn (PI. XVI phot. 2). These con- tTue, a fernating with an herbaceous growth in which ^--^ ^^f^J^ Zjuhsa are conspicuous. Shortly before the Pass is reached he last Rhodod ndron patches are left behind and Geraniun. pasterus takes fu 1 pos- fe^on of the fi'elds; its foliage, in autumnal colour of pale^^^^^^^ tints t^e mountain slopes for hundreds of metres around (PI. ^VI, P^t. 3)Jhe only other nlant occurring with Geranium in any quantity is a small Dryas Among the less 'abundant herbs at the Pass are Tara^un., AUhen^la seriZ, iyosoiis alpestris and Saxifraga sibirica.
