GENTIANACK M. 81 
Corolla funnelshaped-rotate, bearded at the throat ; segments 
broadly obovate, shortly fimbriate round the margins. Seeds few, 
winged, ciliated. 
In ponds and by the margins of slow-running rivers. Rare. In 
the counties of Sussex, Surrey, Oxford, Bucks, Berks, Gloucester, 
"M iddlesex, Essex, Norfolk, Cambridge, Huntingdon, Northampton ; 
in all of which it appears to be wild. In the counties to the 
north of these, though it occurs as far north as Perth and Lanark, 
it has probably been planted. 
England, [Scotland.] Perennial. Late Summer 
and Autumn. 
Rootstock rather slender, creeping in the mud, and producing at 
distant intervals tufts of roots, alternate leaves, and flowering-stems, 
which reach the surface of the water, the latter generally spotted 
with red. Petioles varying in length according to the depth of the 
water ; those of the leaves from the rootstock not dilated at the 
base, those on the flowering-stem much dilated and sheathing at the 
base. Leaves 1J to 4 inches in diameter, rather longer than broad, 
shining green blotched with blackish - purple above, dim and 
usually pnrple below, roughened and thickly dotted with small 
glands. Umbels sessile, of numerous flowers, expanding one after 
the other. Flowers 1 to lj inch across, bright yellow, the corolla 
very thin in texture, strongly bearded at the throat. Stamens in- 
cluded. Capsule flask-shape, acuminate, green often tinged with 
purple, longer than the calyx-segments. Plant glabrous. 
Hound-leaved Buckbean. 
EXCLUDED SPECIES. 
GENTIANA ACAULIS. Lin,,. 
Eng. Bot. No. 1594. 
Stated to have been found wild near Haverford West, Pem- 
brokeshire, and on the sand-hills, near Liverpool ; but doubtless 
this plant of the Alps had either escaped from cultivation in these 
stations, or G. pneumonanthc was mistaken for it. 
S WERT I A PERENNIS. Linn. 
Eng. Bot, No. 1441. 
Said by Hudson to have been found in Wales by Richardson, 
but no one else has met with it, and there are no British specimens 
to vouch for its occurrence there.
