SUNDEW. 
Ri Gok leh ed, 
PTHE flower confifts of five petals, regularly difpofed into a hollowed’ form: the feed-veffel is 
oval, and has five valves at the top, but contains only a fingle cell: the cup is formed of a 
fingle piece, divided into five fegments, and remains when the flower is fallen. 
Linnzus places this among the pentandria pentagynia s ‘the threads i in “the flower being five, and the 
ftyles from the rudiment of the fruit of the fame number. 
This author has taken away the antient hame of this genus, which is ros Salis, and dlls’ it drofera. 
As a generical name confifting of more than one word is always i improper, ’ “and as, befide the name 
ros falke, there is a familiar one always underftood, and ufed as fynonymous with it, that is ‘rorella, I 
thave chofen this ‘for the name of. the genus; every one converfant in the léaft with thefe ftidies 
‘knowing it. 
DIVISION IL 
a.2.Common Sundew. 
Rorella vulgaris. 
The root is compofed of a few, flender. crooked 
:fibres: 
The leaves rife from: it in-a little clufter. ten-or 
a dozen together, and form.a very fingular ap- 
»pearance: each has its long-and flender footftalk; 
and -both that and the leaf are very hairy : the 
body. of the leaf is roundifh, or a little inclining 
to oval: the colour is a dingy purple, and the 
fubftance is flefhy. 
The hairs that grow on this, and on the. foot-. 
ftalks, are long, robuft, and yellowifh; and’ 
they differ greatly from thofe of any other known 
_ plant, -except the f{pecies of the fame genus: ‘they) 
are often -waved-or crooked, and there ftand on) 
. the leaves large:drops of a tranfparent fluid in the 
»midft of the hotteft days: from this the plant 
received its name of fundew. 
The ftalk rifes in ‘the centre of this tuft of 
leaves, and is upright, fingle, undivided, and fix 
inches high: its colour is purple, and it has no 
leaves or “branches only that at the top it fome- 
times divides into two parts. 
The flowers: ftand.on the divifions, ten or a 
dozen on each: they are fmall, and rarely keep 
long open. 
The feed-veffel is fmall and oval ; and the feeds 
are alfo oval, numerous, and fmall. 
It is common on the boggy parts of heaths ; 
and flowers in June. ; 
C. Bauhine calls it Ros folis folio rotundo. O- 
thers, fimply Ros folis. Several of the following 
fpecies of this genus agree with this in having 
no leaves on the ftalk: it is on this account the 
claffical character fays, thefe plants have leaves 
; !alternate,-or not in pairs: thofe from the root 
grow. all from a.fingle head, and they are all the 
leaves belonging to thefe kinds,

BRITISH SPECIES. 
2. Roundifh-leaved perennial Sundew. 
Rorella ratuadsfolia perennis. 
The root confifts, not of a few flight fibres, 
.as in the preceding, but. of athick tuft of them, 
Apreading every way ‘to a ‘confi iderable length, 
from the feveral parts of one Principal, flender, 
and, long, body. 
The, leaves rife i in a little elufter, but rarely 
more than fix or feven together = they have long 
footftalks, and ftand more upright than in the 
common fundew : the leaves themfelves are round- 
ifh, but approaching to oval, and are of a thick, 
flefhy fubftance : they are covered with fhort and 
ftiff, yellow hairs, and generally have drops of .a 
tranfparent liquor. on them in the heat of the day, 
The ftalk is naked, fender, upright, and four 
inches high. 
The flowers grow at the top in a feries of 
eight or'ten together; and they open more fr eely, 
and ftand longer, than thofe of cominon fundew : 
they are fmall and white: | 
“The feed-veflels are ‘oblong, and the feeds nu- 
merous and roundifh. Di . 
It is comnion ‘on bogs, with the former, but 
is overlooked. Tt flowers i in July. 
_ Ray calls it Rorélla’ rotundifolia perennis. 
3. Small longifh-leaved perennial Sundew. 
Rorella pufilla longifolia perennis. 
The common fundew is fometimes obferved to 
have the leaves approaching to an oblong form, 
and has thence been divided, by Cafpar Bau hine 
and others, into two fpecies, the latter called 
ros folis folo oblongo ; but that is only a variety 
of the common kind: the plant here treated of 
_ differs much more obvioufly and eflentially, and 
is a truly diftinct fpecies. 
The root is a great tuft of thick, black, and 
crooked fibres,
