This eastern variety of the species is distinguished from the typical plant by having 

 the leaves less rugose, thinner, and tapering into the petiole. The stem, the calyx, and the 

 under sides of the leaves are covered with very short, soft glandular hairs. The limb of 

 the corolla is flat. The variety is of rather common occurrence in the Sayansk district, 

 in alpine and subalpine meadows, and in thickets. All the specimens in my collections 

 are distinguished by being few-flowered, each scape bearing only 3 — 6 flowers, thus 

 agreeing perfectly with Lehmann's record in Monogr. Gener. Primular. (1817) p. 38. 

 Ledebour, however, expresses himself in the following way concerning this species: 

 „Umbella multiflora: floribus non raro 15 (neque, ut vult cl. Lehm. 1. c. 3 — 6)." The calyx- 

 lobes are slightly, but not distinctly recurved, and of the same length as the ripe capsules. 

 KoRSHiNSKY records the ripe capsules to be slightly shorter than the calyx. (Tent. Fl. 

 Ross. p. 284 in Mem. Acad. Imp. Sc. St. Petersbourg, 1898, Vol. VII). Specimens collected 

 at the end of July are mostly past flowering, not unfrequently with the ripe capsules al- 

 ready emptied. 



Distribution: The above variety is distributed in the Ural, south-western Asia, the 

 Altai, the Sayansk district (northern Mongolia).

The specimens of this rather polymorphic plant are especially distinguished by the 

 rather thick scape, at times drooping, only slightly projecting beyond the leaves, and 

 bearing only 2 — 3 flowers — at least during the flowering — on rather short pedicels, only 

 from 5 — 10 mm. long. The bracts are very narrow and acutish, nearly linear, 5 — 8 mm. 

 long. The calyx is completely glabrous, about 6 — 7 mm. long, of an almost coal black 

 colour (at any rate when dried), and about to the middle split into lobes, slightly acumi- 

 nate at the top. The tube is about twice as long as the calyx, the limb about 1,5 cm. in 

 diameter, of a dark purple hue. The whole plant is completely glabrous, and not mealy. 

 The leaves are 1 — 2 cm., generally 1,5 cm. broad, and 5 — 8 cm. long, rather argute serru- 

 late at the margin, gradually tapering and decurrent into the petiole. The specimens found 

 are very nearly alhed to the variety typica Regel in Acta Hort. Petropol. Ill (1874) p. 135, 

 which are recorded, however, to have mostly broader leaves, and the calyx of a greenish 

 purple colour, with considerably longer lobes. 



Distribution: The species is distributed in northern Asia Minor (the Pontus Moun- 

 tains) and south-western Asia to the Himalayas, the Altai, the Sayansk district, the 

 Yablonoi, Kamtchatka, China, North America (?). Var. typica Regel occurs in the Altai 

 and the Sayansk districts (northern Mongolia).
