PLATE 27. 
N. turritella. Surface view of a small plant, showing eight cylindrical branches densely clothed 
with leaves; flowers are seen protruding from the flat surfaces; the individual leaves 
consisting of numerous lobule are well shown. (Cf. Pl. 28. figs. 11, 16, and text-fig., p. 202.) 
(A. W: Hill, 81.j 
. The same plant seen from the side ; only the light upper portions of the branches project above 
the soil. The lower portion is protected by the persistent vagin: ; below, the scars of leaf 
bases are visible and the root shows wrinkling. 
. N. Azorella. A small piece of the densely-branched hard cushion. The branches are clothed 
with the persistent vaginz, and at the apex of each a rosette of minute leaves can be 
seen with a single centrally-placed flower. A single branch is from 1-l:5 em. in diameter. 
(Cf. Pl. 28. fig. 15.) £ nat. size. (Weberbauer, 957.) 
. N. pedatiloba. A whole plant showing leaf-scars and root-shortening ; the leaf-laming, 
composed of numerous lobule, are densely hairy on the upper surfaces. (A. W. Hill, 78.) 
(Cf. Pl. 28. fig. 12.) Nat. size. 
. N. pedicularifolia. Showing the palmatisect leaf-lamina with its crisped, pinnatifid or bipinnatifid 
segments; in the open flower the long narrow petals can be seen. (Herb. Kew.) # nat. size. 
Probably the type of N. incana, Turez. 
N. argyllioides. A specimen collected by Weddell; formerly considered by him to be Malvastrum 
ulophyllum, A. Gray. The somewhat indefinitely palmatifid laminze should be noted and com- 
pared with fig. 7. Sometimes the leaf-lamina is more or less oval in outline and deeply 
lobed. (Weddell, 4394.) 
. N. argyllioides. A well-developed specimen of my own collection to compare with fig. 6. The 
leaves show various stages from a palmatisect type with equal segments towards a bipinnate 
type with the median lobe strongly developed. The adnation of the pedicels and stipules to the 
petioles is well shown. The tomentum is on the upper surface of the leaves, and is composed 
of very fine stellate hairs, giving the plant a grey dusty appearance. (A. W. Hill, 80.) X lj 
. N. anthemidifolia. A plant in surface view, showing the bipinnatifid leaves with a stellate 
tomentum on the upper surface. "The vaginz are provided with long silky stellate hairs, 
which are seen in the centre of the specimen. (Cf. Pl. 30. fig. 1.) (D’Orbigny, 1354, Herb. 
Mus. Paris.) 
This plant is the type of N. cheilanthifolia, Turcz., and is the same as D'Orbigny, 1357, 
the type of N. discolor, Turez. Both had been previously named Sida anthemidifolia, Remy: 
. N. longissima. In side view, showing the bipinnatifid leaves with few ren and the adnation 
of the stipules and petioles. (4 nat. size. ) 
. The same. The calyx on the left is full of ripe carpels, the hairs of which are seen protruding. 
(Weberbauer, 2785.)
