ALPHABETICAL LIST OF PLANTS 329 



p. a. niarginata^ another variety, has a white margin to its 

 leaves, and yellow flowers. It is very liable to be confused with 

 P. margmata, a very distinct plant. 



P. Balbisii (see P. auricula^ var. ciliata). 



P. Bulleyana. — Rich, moist loam in half shade. Leaves like the 

 common Primrose. Flowers orange-yellow, shaded on the outside 

 with apricot. Borne in whorls, and rising 9 to 12 inches high. A 

 new Chinese introduction, and said to be quite hardy. 



P. calychia (see P. glaucescens). 



P. capitata. — Cool, shady position in good soil of peat, loam, 

 leaf-mould, and sand. The flowers, which are of a deep violet-blue, 

 thickly coated with a white powder on outer and lower parts, are 

 borne in dense globular heads on stems 6 to 9 inches high. It 

 blooms in the autumn. It is hardy, but reputed only a biennial, 

 though Mr Farrer says he had a clump for seven years, growing on 

 a well-drained slope, in light soil, which treatment I am trying, but 

 have not had time to fully test its efficacy, though, so far, all is well. It 

 can easily be raised from seed, and is one of the gems of the genus. 



P. capitellata. — Shady position in very moist peat and sandy 

 loam. Forms a compact plant, with rather thick leaves and close 

 heads of purplish or deep red flowers, borne about 9 inches high. 

 Hardy and vigorous. A very attractive and uncommon plant. 



P. carniolica (syn. P. Freyeri and P. jellenkiana). — Requires a 

 half-shady spot in gritty loam. It should be grown wedged in 

 between rocks, in a sloping position. Forms rosettes of smooth 

 green leaves. Flowers bluish-purple, with a white centre. Blooms 

 in July, and of vigorous growth. Increased by division and seed. 



P. cashmeriana (see P. denticulatd). 



P. ciliatum (syn. P. auricula ciliata). 



P. clusiana. — Half-shady position in calcareous and gritty loam. 

 Leaves dark green, margined with white. Large, handsome violet- 

 carmine flowers, which bloom in April. Vigorous habit, and one 

 of the most beautiful of the genus. 1 1 much resembles P. glaucescens^ 

 which IS often sold for it, whose petals are not divided as they are 

 in P. clusiana. 



P. Cockburniana. — Half-shady position in moist, rich loam and 

 leaf-mould. Forms rosettes of primrose-like leaves. Erect stems 

 rise about 8 to 12 inches, and bear in whorls brilliant orange- 

 scarlet flowers. A unique shade in the genus. Quite hardy, but 

 unfortunately only a biennial ; but it can readily be raised from 

 seed, which germinates quickly if sown as soon as ripe. A recent 

 introduction, and a most beautiful and valuable addition. 



P. cortusoides. — Requires a sheltered, shady position in rich, 

 sandy loam and leaf-mould. Leaves soft and wrinkled, and spring- 

 ing from creeping stems 2 to 4 inches long. The flowers deep rose-
