12 MR. G. WATT ON SOME 
forms that I ean suggest. I suspect that all are forms of the 
beautiful P. nivalis, Pallas, of Siberia and Central Asia."

ceolatis spathulatisve acutis crebre argute denticulato-crenatis 
rarius integerrimis subtus flavo-farinosis, inflorescentia farinosa, 
calycis lobis linearibus lanceolatisve acutis v. obtusis, corolle 
aurez lobis orbicularibus et emarginatis v. obeordatis integris v.

Hook. Bot. Mag. t. 4356. 
Var. 2. purpurea ; foliis ut in var. 1, sed rarius dentatis v. cre- 
natis sepius latioribus, floribus interdum in verticillos superpo- 
sitos dispositis, calycis lobis interdum fere polliearibus lineari- 
oblongis obtusis, corolla pallide v. saturate purpurea, lobis obcor- 
datis v. bifidis, capsula 1-1-pollieari.—P. purpurea, Royle, lll. 
Pl. Himal. 311, t. 77. f£. 2: Duby in DO. Prodr. viii. 40;

Nep. 80. P. Jaeschkiana, Kerner in Bericht. des Naturwiss. 
medicin. Vereins Innspr. Jahrg. i. Heft ii. 97. (Tas. IX.) 
Var. 3. Mooreroftiana. Minor, vix v. non farinosa, foliis ob- 
lanceolatis acutis sæpissime integerrimis, scapo breviore paucifloro, 
calycis lobis angustis acuminatis, corolla purpurea.—P. Moor- 
eroftiana, Wall. Cat. 4988. Western Tibet. (Tas. X.) 
Var. 4. macrocarpa; folis subtus farinosis 2—5-pollicaribus 
oblanceolatis obtusis acutisve, calyce majore 1-£-pollicari fere 5- 
partito segmentis lineari-oblongis obtusis coriaceis, capsula 
pollicari.—Sikkim Himalaya, alt. 15,000-17,000 ft., J. D. Hooker. 
Var. 5. lineariloba; corolle purpures lobis angustis divari- 
eatis.—Tibet north of Sikkim, at a great elevation. Flowers 
alone of this were procured by Sir J. D. Hooker, who does not 
doubt their being referable to a very starved form of var. 
purpurea.
