220 MR. A. W. HILL—REVISION OF 
some 10 em. in diameter, formed by the close association of the numerous more or less 
vertical branches of the caudex (Pl. 27. fig. 3). The leaves are arranged in dense 
cylinders of about 1 cm. in diameter, and only those at the surface of the cushion are 
in a living condition. The centre of each tiny rosette is occupied by a flower. The 
specimens of both these species brought home by Weberbauer are peculiar in that the 
flowers appear to be unisexual, neither carpels nor their rudiments having been found. 
The corollas are about 6-7 mm. long, with a basal tube and a small head of stamens 
(Pl. 28, fig. 15). 
N. Azorella is easily distinguished from VN. congesta by its rounded semicircular 
laminze, by the broad vaginsz, and by the free parts of the stipules being broader and 
shorter than in N. congesta (Pl. 28. fig. 15). In the latter species the leaf-laminz are 
rather four-angled in outline, and they form a larger and less dense mass than in 
N. Azorella; the stipules also are filiform-subulate and acute. The upper parts of the 
branches are covered by the old dead leaves, and lower down only the vagin: remain, 
which are covered with bristle-like stellate hairs on their outer sides. Large orange- 
coloured, glandular nectaries are seen at the base of the calyx (Pl. 30. fig. 3).

This species shows fairly close resemblance to N. artemisioides (q. v. p. 228). The 
nectary-glands are figured (Pl. 30. figs. 2, 4). 
8. NororRICHE AURICOMA, A. W. Hill.— Fruticulus depressus, cespitosus, pulvinatus, 
breviter caulescens; caudex ramosus. Folia aggregata, incano-auricoma ; petiolus 
circa 1 em. longus, utrinque dense incano-stellato-tomentosa ; stipule imperfecte ; 
lamina late cuneata, flabelliformis, ad medium 5-secta, 5-6 mm. longa, 10 mm. lata, 
supra et infra dense incano-stellato-tomentosa, segmentis plus minusve trilobis, 
segmento medio 3-5-lobato, lobis brevibus obovatis obtusis carnosulis supra 
auricomis. Flores fere ad petiolum medium insidentes. Calyx supra medium 
5-lobus, circa 9 mm. longus, extra stellato-tomentosus, lobis triangulari-obtusis 
circa 3 mm. longis apice carnosulis auricomis intus tomentosis. Corolla lutea, 
circa 1 em. longa; petala ovato-cuneata, unguiculata, retusa, basi in tubum circa 
2 mm. longum coalita. Carpella 6-8, matura non visa.

This species forms little cushions of about 3 em. in diameter; the caudex, which is 
fairly slender, apparently branches to a certain extent above ground. The stipules as à 
rule are not properly developed. 
N. auricoma differs from all other species in having orange tips to the leaf-lobulæ and 
calyx-teeth. It is further distinguished by possessing yellow flowers, which àre 
uncommon in the genus.
