The. margin of the leaf is sHghtly undulate, and on each side dissected into 6 hroad, 

 semiorbicular lobes, rounded at the top, each of them 5, rarely 3- or 7-toothed. The scape 

 is considerably longer than the leaves, from 20—35 cm. long, pubescent, especially so at 

 the base. The bracts are lanceolate, 6—7 mm. long, shghtly nerved, with short, but rather 

 dense hairs. The flowers are 4 — 10, on leather strict and slightly hairy pedicels, measuring 

 about 2 cm. in length. The calyX is 5—8 mm. long, to about the middle cleft into lanceo- 

 late lobes, with scattered, short hairs, or at times nearly glabrous. The flowers are large, the 

 limb 18—26 mm. in diameter; the petals ratlier deeply emarginate, reddish violet. The tube 

 is about 1 cm. long, projecting considerably beyond the calyx, its colour rather varying, 

 from a dark violet to a pallid yellowish green. With regards to the margins of the petals, 

 the species exhibits the same features as the nearly allied P. cortusoides L., being either 

 entire or serrulate. I therefore separte these respectively as /'. integerrima nov. f.: corol- 

 lae lobi integii and f. denticulata nov. /'.. corollae lobi denticulati. 



This species is rather common on the islets in the rivers Yenisei and Abakan, where 

 occurring in grass-grown places, in thickets, etc., in full flower at the beginning of June. 

 Specimens taken in different localities prove to be rather varying in pubescence, in the 

 length of the scape, the length of the calyx-lobes, the shape of the limb and of the tube. 



P. patens Turczan. is undoubtedly very nearly allied to P. cortusoides L., and I am 

 inclined to look upon it as an eastern subspecies of the latter. Their geographical distri- 

 bution also seemed to be indicative of this assumption being right. My specimens, col- 

 lected in the transition zone between the geographical areas of the two said species, 

 thus seemed, in many respects, to constitute intermediates between them. 



Distribution: Primula patens occurs in eastern Asia, westwards to about the Altai 

 region. In western Siberia it is replaced by Primula cortusoides L.

About Karatus and Kushabar, on hills and in small thickets. Past flowering at the 

 beginning of July. 



Distribution: The variety is distributed from eastern Prussia, eastwards through the 

 south-eastern portion of middle Europe, Caucasia and south-western Asia, southern Sibe- 

 ria, eastwards to the government of Yeniseisk.
