at the margin, one usually bearing a small tubercle, leaves 
roundish-cordate ample obtuse, whorls leafless crowded, flowers 
monoecious. E. B. S. t. 2694. 
Road side from Helensburgh to the head of the Gare Loch, and 
in 2 or 3 stations in that neighbourhood ; Glen Luss ; near Dollar ; 
Glen Farg, Perthshire. One-ash, Derbyshire. U- 7. — Its root was 
formerly employed in place of rhubarb, and much cultivated by the 
monks and hermits, near whose former abodes it is principally met 
with. Leaves a span broad, cordate, very obtuse, wrinkled, and reti- 
culate ; upper ones ovato-lanceolate , whorls of flowers very dense. 
Dr. Meisner refers the figure in E. B. to II. longi/olius DC., hut that 
must surely have been by mistake, as the radical leaves of the two 
species are quite dissimilar. R. longifolius has the leaves of It. 
aquations, hut the sepals of R. alpinus, and is R. domesticus Hartm. 
7. 11. sanguineus L. ( bloody-veined , and (d.) green-veined 
D.); enlarged sepals narrow-oblong obtuse entire, one at least 
bearing a tubercle, leaves ovato-lanceolate, lower ones somewhat 
cordate, whorls distant on long generally leafless branches. — 
a. leaves with bright red veins. E. B. t. 1533. — p’. leaves 
with green veins. R. viridis Sibth. R. Nemolapathum Ehrh. 
Shady pastures, woods, and road-sides. — a. rare. — (8. more fre-

8. R. conglomerate Murr. (sharp D .) ; enlarged sepals linear- 
oblong obtuse entire or obscurely toothed all bearing a tubercle, 
leaves oblong pointed, lower ones cordate or rounded at the 
base, whorls distant leafy. R. acutus Sm. : E. B. t. 724. 
Watery places, not uncommon. 2/.. 6 — 8 Much resembling 
var. P. of tile last species, and appearing to differ chiefly in its more 
leafy whorls and enlarged sepals all constantly tuhercled. Smith con- 
siders this to he the R. acutus L. ; but it can scarcely be the species 
known under that name on the continent, which has ovate rather 
acute enlarged sepals, each with a very large red tubercle. It is the 
R. Nemola/iathum of Campdera and some other continental botanists. 
9. R. pulcher L. (Fiddle D.) ; enlarged sepals triangular- 
ovate reticulate with prominent veins deeply toothed, one of 
them principally bearing a tubercle, lower leaves panduriform 
or cordate oblong obtuse, upper ones lanceolate acute, stem 
spreading. E. B. t. 1576. 
Pastures, way-sides, &c. If.. 6 — 8. — Stems procumbent; branches 
very straggling ; whorls distant, on slender leafy branches. 
10. R. maritimus L. (golden I ).) ; enlarged sepals narrow 
deltoid acute, each fringed with 2 — 4 setaceous teetli as long as 
the sepal and bearing a narrow oblong tubercle, whorls much 
crowded many-flowered leafy, leaves linear lanceolate all at- 
tenuate at both ends. E. B. t. 725. R. aureus With. 
Marshes, principally near the sea. It. 7, S. — Well distinguished
