MR. A. W. HILL—REVISION OF 
N. sulphurea. A somewhat irregularly shaped leaf. The median lobe is well developed and 
shows a bipinnate character; one of the filiform stipules is shown. x 2. (Weberbauer, 
963.) 
A piece of the same, more highly magnified, to show the many-rayed stellate hairs which cover 
the whole plant with a dense woolly tomentum. ; 
. N. pseudoglabra. A pinnate type of lamina, with the lateral lobes still strongly developed, 
glabrous in the adult condition; the vagina and stipules ciliate. x lj. (Fiebrig, 3186 A.) 
. N. glauca. Pinnate type of lamina, with the segments of more or less equal value; the lobes 
are broad and obtuse; stipules filiform, covered all over with glaucous velvety tomentum. 
x 2. (Fiebrig, 3186.) 
N. saltensis. Young leaf showing the lamina, vagina and subulate stipules covered with a 
ciliate tomeutum. 
. An old leaf of the same species, with a calyx enclosing nearly ripe fruits ; the pinnate type of 
the lamina is well seen—at this stage it is almost glabrous. Slightly less than nat. size. 
(Hieronymus and Niederlein, 41.) 
N.sericea. Leaf with calyx showing the lamina finely cut into narrow segments, with a 
tomentum of few-rayed silky stellate hairs. 
The same with flower, the leaf-cutting more plainly seen. Both nat. size. (A. W. 
Hill, 82.) 
. N. Matthewsii. Leaf showing the development of the pinnate type of lamina from a 5-lobed 
leaf by the elongation of the median segment; the lobes are few, narrowly oblong, acute ; 
the upper surface of the lamina is covered by a soft dense tomentum, and there are ciliz at 
the apices of the lobes. x 3. (Matthews, 682.) 
. N. pichinchensis. Showing the lamiua cut to the middle, covered above by a soft velvety 
tomentum, glabrous and varnished below. x 2. (Jameson.) 
N. Macleanii. Lamina with broad stipules ; the segments are cut nearly to the base of the 
lamina, the tomentum is composed of loose shaggy hairs. (Maclean.) 
. N. Hartwegii. The cuneate lamina is cut to the middle into five segments, the median one 
only being 3-lobed ; the tomentum is of loose shaggy hairs. x 2. (Hartweg, 918.) 
. N. aretioides. The upper surface of the lamina and vagina; the lamina cut to rather below 
the middle lobes, concave, with a fairly dense shaggy tomentum on the upper surface. 
The same leaf showing the lower surface and the stiff stellate spines on the back of the vagina. 
x 4. (Weberbauer, 289.) 
. N. stenopetala. The lamina showing the development of the pinnate type of leaf, from a leaf 
like that of N. pichinchensis ; the lower surface is glabrous and varnished, the upper being 
covered by a velvety tomentum. x 2. (Maclean.) 
N. lanata. Leaf with young flower-bud, the five lobes are more or less pinnately lobed and 
the whole leaf is covered with a woolly tomentum. 
N. pusilla. Annual; the whole plant showing the more or less entire lamina with the stipules 
adnate to the bases of the leaves, except in the case of those to which the flowers are adnate. 
x 4. (Weddell, ann. 1847.) 
The same. Surface view of a plant showing the horizontal branches terminating in rosettes of 
leaves. About nat. size. (Weberbauer, 2788.) 
A small plant, side view, showing the root-system and two horizontal branches with their leaf- 
rosettes. 
N. oe Annual; the entire plant densely covered with hairs. x 1$. (D'Orbigny : 
1859.)
