campanulatus, 9 mm. longus, supra medium 5-lobus, utrinque dense stellato- 
pubescens, lobis 9:5 mm. longis triangulari-oblongis obtusis, apicibus carnosulis 
glabris. Corolla pallide violacea, medio purpurea, 1:3-1:5 cm. longa, plus minusve

Peru: Dep. Arequipa, Volcano El Misti, 4000-5000 m., 4. W. Hill, 81 (Herb. Kew. : 
Pl. 27. figs. 1, 2; Pl. 28. figs. 11, 16; Pl. 30. figs. 6, 13; text-fig., p. 202); Vulcan 
El Misti, Alto de los Huesos, 3700 m., Weberbauer, 1421 (Herb. Mus. Berol.). 
This species appears to be confined to the slopes of the voleano El Misti above 
Arequipa: it was found both by Weberbauer and myself and I was able to traverse its 
whole vertical range of about 1000 metres. The ultimate branches of the plant, 
covered by their dense felt of leaves, stand out of the black volcanic ash like little turrets 
to a height of from two to five centimetres (text-fig., p. 202, and Pl. 27. figs. 1, 2). The 
flowers are borne at the apices of the leaf-rosettes and are in striking contrast to their 
surroundings. In shape they resemble small Crocus-flowers and with their pale violet 
colour and deep purple centres form conspicuous and beautiful objects, when in fuli flower 
about the middle of March. The leaf-lamina is trifid in structure, with a small median 
segment (Pl. 28. figs. 11, 16), but appears to be 7-11-lobed on account of the deep cutting 
of the two lateral lobes. The young leaves are densely hairy all over, but when older the 
tips of the lacinul are glabrous and resemble finger-tips sticking out of the fingers of a 
minute woolly glove (Pl. 28. figs. 11, 16). ‘The lacinulw are arranged in little packets of 
4or 5, with their upper surfaces turned inwards and closely wefted together by their hairs. 
Of the eight carpels usually seen in each flower (Pl. 30. fig. 13), only —Tel rule 
comes to maturity and affords a suggestive link with the apparently moncecious species 
N. Azorella and N. congesta (v. pp. 219, 220). | 
A figure of the corolla of this species is given (Pl. 30. fig. 6) to show a typical case 
ofa well-developed fusion of corolla and staminal column to form the corolla-tube.
