rarely of a red-brown, or blue-black, glabr., rarely, when 
mature, having a tuft of hairs at the top . . 3 
3. Ls tomentose on both sides or only (and always) under¬ 
neath, green above and apparently glabr. but almost 
always, at least those of the inflorescence, with a sprink¬ 
ling of very s m a 11 .s t e 1 la t e hairs (visible when 
magnified 50—60 times) ..... 4 
— Ls never tomentose above, green underneath or tomen¬ 
tose and then with or without simple hairs above, but 
without stellate hairs. R.. tomentosus glabratus may be 
looked for here; comp. No. 636 . ... 3 
Tomentosi. 
4. Stipitate glands hardly ever wanting either on the shoot 
or inflorescence. Stipules linear. Lower lateral leaflets 
shortly stalked. Seps reflexed on the fr. Fr. glabr. Leaf¬ 
lets rather small, oblong-obovate, coarsely lobed-dentate, 
with cuneiform, entire base. Panicle narrow, fairly dense. 
Pets white, rather inclined to yellow. Petiole channelled. 
—Var.: Ls green above, (var. glabratus), or ash-gray- 
tomentose (v. canescens); shoot rarely tomentose-villous 
v. villicaulis) or with unequal prickles and numerous 
glands (v. Lloydianus Gen., if the Is are, at the same 
time, green above). —T. Y. B. 0. J. L. Z. S. 
Tomentosus Borkh. 636. 
— Glands few or 0. Stipules more or less foliaceous as in 
R. csesius. Lower lateral leaflets sessile or v ery shortly 
stalked. Seps erect or spreading on the fr., rarely all 
reflexed. Fr. glabr. Hybrid forms between R. tomentosus 
and R. csesius. 
— Glands more or less numerous, never wanting. Stipules 
linear. Lower lateral leaflets distinctly stalked. Seps re¬ 
flexed on the fr. Ovaries glabr. or pubescent. Hybrid 
forms between R. tomentosus and those species which have 
stipitate glands *) 
— Glands absolutely 0. Stipules linear. Low r lateral leaflets 
distinctly stalked. Seps rellexed on the fr. Ovaries glabr. 
or pubescent. Hybrids of R. tomentosus with the species 
which have equal prickles and no stipitate glands. These 
hvbrids differ from the Discolores in the channelled 
v 
petioles, the inflorescences with furrowed axis, the fr. 
incompletely developed and above all in the presence 
of small stellate hairs on the ls, which are scarcely ever 
wanting in the hybrids of R. tomentosus. Comp, also 50 
*) Among these are R. tomentosus-vestitus and R. tomentosus-Radula 
— Hybrid forms between R. tomentosus and the Glandulosi have not yet been 
observed in Switzerland.
