8 FLORA OP TASMANIA. [Ranunculacea . 
incrassatis integerrimis paucidentatisve, scapis brevibus 1-floris, sepalis patentibus late oblongis, petalis 
flavis obovato-oblongis in unguem brevem angustatis, glandula nectarifera parva crassa subsemilunari a

Hab. In alpine districts, elev. 4000 feet, abundant in wet places, summit of Western Mountains, 
Arthur's Lakes, etc., Lawrence, Gunn. — (Fl. Jan.) 
This is one of the half-starved-looking alpine Ranunculi, that can only be properly characterized after the in- 
spection of very many specimens, for, like its alpine congeners in Europe, it probably assumes many forms. The most 
hairy specimens resemble small states of R. lappaceus 8, but the glabrous ones appear widely different. The styles 
are neither so long as in lappaceus, nor so short as in liirtus. The nectarial scale, forming a small semilunate promi- 
nent gland at some distance from the base of the petal, seems the most tangible character.— Root of thick fibres. 
Cottum very thick. Leaves generally depressed, spreading or decurved, 1-H inch long ; petiole glabrous, or very 
rillous with spreading hairs; lamina always nearly or wholly glabrous, entire and lobed, or cut, or three-lobed, or 
pinnately five-lobed ; segments coriaceous, with thickened tips, quite entire or a little lobed. Scapes short, stout, 
erect or decurved. Flowers solitary, i inch across. Sepals oblong, membranous, concave, glabrous. Petals 
obovate-oblong, narrowed into a short claw, yellow. Carpels with short curved styles.

v. glabratus, foliis longe et crasse petiolatis ovalibus oblongis cuneato-oblongisve apice 3-5-fidis tnlobisve 
v. grosse dentatis, scapis radicalibus elongatis v. in axillis foliorum, floribus parvis, petalis parvis, carpellis 
paucis, stylo brevi. {Gunn, 228.) 
Hab. Alpine swamps at Arthur's Lake, and on the Western Mountains, elev. 4000 feet. — (Fl. Jan.) 
The original specimens of this look very distinct from any other Tasmanian species ; but a second supply from 
Mr. Gunn presents many forms that are intermediate between it and the last. Mr. Gunn also remarks that it 
■rrows in swamps, and is under water during a portion of the year, which may account for some of its peculiarities. 
To me it resembles a luxuriant state of R. nanus, becoming caulescent or proliferous, and bearing either scapes 
or axillary peduncles. Some flowers appear to be apetalous, which is a further sign of abnormal condition ; and its 
whole history requires elucidation in its native place. The nectary is as in R. nanus. 
b. Stems creeping orflagelliferous. 
8. Ranunculus inundatus (Br. in DC. Syst. i. 269) ; glaberrimus, debilis, caule repente v. submerso

pedicellatis, pedicellis radicalibus oppositifoliisve, sepalis obovato-rotundatis, petalis 5 stipitatis lamma lineari- 
oblonga basi fovea nectarifera magna transverse elongata incrassata instructis, receptaculo piloso, carpellis 
(sicco rugosis) 6-8, stylo elongato.— DC. Prodr. i. 34; Hook. Journ. Bot. i. 242 ; Gray in Bot. of Wilkes' 
Explor. Exped.p. 9. {Gunn, 396, 774.) 
Hab. Fresh and brackish swamps, abundant ; sometimes growing in deep water, on which the leaves 
float, Gmm.—{m. Nov. Dec.) {v. v.) 
Disteib. New South Wales, and South-eastern Australia. 
A slender marsh or water plant, everywhere quite glabrous.— Stems creeping, a few inches to a yard long, 
rooting at the joints, where they bear tufts of leaves and scapes, and slender branched stems, which have smaller 
leaves and one-flowered pedicels opposite to them. Petioles 1-4 inches long. Z*?a/ palmately five-lobed, generally 
membranous, cut into five radiating narrow wedge-shaped leaflets, that are variously lobed and cut ; sometimes the 
leaves are multifid, with very slender linear lobes. Peduncles as long as the petioles, or shorter. Flowers -i of an
