dense lanato-stellato-tomentosa ; lamina spathulata vel plus minusve rotundata, 
integra, rarius paullo lobata, 3-4 mm. longa et lata, carnosula, supra et infra dense 
velutino-stellato-tomentosa. Flores fere axillares, imæ basi petioli insidentes, 
breviter pedicellati. Calyx fere ad medium 5-lobus, 1 em. longus, extus infra

The small spathulate or obovate leaves (Pl. 28. fig. 3) in this interesting little species 
are entire by reduction. In some cases the lamina shows a slight lobation at the apex. 
As regards the tomentum and general colour, this plant is similar to N. compacta; and 
it is possible that this species may be its closest ally. The stipules are filiform and are 
often not well developed, as is also the case in that species, and one of them is frequently 
found to be adnate to a greater distance along the petiole than the other. The caudex 
appears to branch somewhat above the level of the ground (cf. N. compacta, N. auricoma). 
The whole plant is covered by a yellowish tomentum.

The whole plant is slender, forming small rosettes. The leaf lobule are somewhat 
fleshy, slightly superposed (Pl. 28. fig. 5) and covered with a dense powdery tomentum 
of small stellate hairs.

A densely branched species, with slender and often somewhat long branches forming 
à compact cushion; the root-system is much divided. The reniform leaf lamina shows 
some resemblance to that of N. obcuneata. The scarlet corolla is a peculiar feature of 
the species, and the petals are irregularly emarginate, having at the apex a large and 
à small subacute point. The carpels are covered with stellate hairs only (Pl. 30. 
fig. 17).

N. Azorella and N. congesta (p. 221) are the two smallest perennial species which have 
yet been found. They both form small hard cushions, like those of the genus Azorella,
