L eaves all radical,, o f an oval heart-shape, obtuse, en--
tire, glabrous, indistinctly nerved1; the younger
•' ones submersed, membranous, waved; the older
ones floating, o f a deep green, somewhat shining,
smooth, dotted when dry, subcoriaceous, tinged
generally with ferrugineous beneath; all upon
long-footstalks; the footstalks much compressed,
almost keeled, dilated at the base, membranaceous,
slightly sheathing, o f a pale rose colour.
F lower-sta lks long, round, single-flowered.
F lower o f the same size as that o f the Marsh Marigold.
Ca l y x o f five divisions ; the leaflets obovate, concave,
fleshy, green, their edges broad, yellow, internally
more yellow.
Corolla : the Petals about ten, very short, between
erect and patent, cuneiform, orange-coloured,
striated above, rather gibbous on the back, and
nectariferous.
Stam e n s numerous; Filaments swoln, bent back at the
points, the outer ones subpetaloid; Anthers composed
of two frequently distinct cells.
P ist il urceolate, green; Germen round, smooth; Style
short, thick, furrowed (the number of furrows
being the same as that of teeth in the stigma) ;
Stigma large, orbiculate, rayed, green,,the margin
with eight to eleven teeth, the teeth deflexed,
,• but after flowering curved upwards^ the rays
elevated, yellow.
P e r ic a r p : a spongy capsule or berry, of a greenish-
• brown hue, crowned with the furrowed style and
the toothed stigma. The rest is similar to the
' Common Yellow Water-lily, except that all the
parts are but half so large. .

This plant is a rare inhabitant of Great Britain; being confined wholly, I believe;'to some of the alpine lakes in
Scotland. I t was discovered in 1809 by Mr. Borrer in a pool near the farm of Corrie-chastel, at the foot (not
upon the summit) of Ben Chonachan; and in Loch Baladren. I t has since been found at Loch Duble, near In-
verary, by Mr. Maughan, and at a small lake at the back of thé Inn of Aviemore, Murrayshire, by W. Borrer
jun. Esq.* ; . fti '
The diminutive size of this species, and its toothed stigma, with the usually small number of its rays, will suffice
•to distinguish it from our N . lutea; but whether it be an equally distinct plant from N . Kalmiana (by mistake
printed Thalmiana in the description of N . lutea) still remains in my mind a point of doubt. Indeed so perfectly
was I formerly convinced of the identity of the N . pumila with the American species, that in my Flora
Scotica the name of Kalmiana is adopted for the Scottish individual; and although, since the publication of that
work, I have had opportunities of examining excellent specimens, in a fresh and dried state, of both the American
and European Nuphar, I am yet unable to satisfy my mind on the subject. In the mean while, I have restored
to the Scottish individual its original name of N . pumila, and have given a representation of the pistil of both, in
order that other botanists may form their judgement from an observation of the only part in which I could find
any fixed difference'at all. ‘ > _ >-
With regard to the size of the two plants, this circumstance is liable to variation in both of them, according to
their place of growth. N . Kalmiana, cultivated as it usually is with us in pots or tubs, is smaller than the figure
here given of N. pumila; but my wild specimens, received from Mr. Boott, are, as nearly as possible, of the size
here drawn, the leaves being, if there is any difference, rather larger. Both species have the submersed leaves pellucid
and membranous; and in both the shape of the foliage is alike: my specimens exhibit the leaves of N . Kalmiana
as slightly hairy beneath, although “ subpubescent ” is given as a character of those of N . Kalmiana by
Decandolle. The petioles are compressed in each, most so perhaps in N . pumila, and their sheathing subtri-
quetrous bases are the same. There exists no difference in the calyx, petals, or stamens. The germen is rather <•
more deeply furrowed in N Kalmiana, and the furrows are purple. The stigma affords, as it appears to me, the \
only constant character. In N . pumila, the ground colour of the stigma is red brown j", the teeth are long, the rays
less elevated and of a duller yellow. The number of the rays varies in both from seven (five to six in Kalmiana)
to eight or nine, or even twelve. . . . '
N . pumila is easy of cultivation in ponds, or in tubs of water, and in such situations retains all the characters I
have here given to it.
I t flowers in June and July, and bears its large berried capsules in the month of October.
