petals unequal toothed at the base with an entire triangular 

 point, one principally tuberculated, leaves oblong-lanceolate 

 wavy, clusters nearly leafless, whorls distinct." Sorrer, in E. 

 Bot. Suppl. t. 2757. — R. cristatus, Wallr, and Fries. — R. acutuSy 

 Spreng. (according to Borr.). 



Marshes, in several counties. Fl. June, July. If.. — Most allied to 

 R. crispus, but the clusters are less crowded, the enlarged valves are 

 unequal in size and more distinctly toothed, and the leaves are broader 

 and less curled. 



4. R. aqudticus, L. (grainless Water Dock); enlarged petals 

 broadly cordate reticulated without tubercles, leaves lanceolate, 

 the lower ones cordato-oblong crisped and waved, whorls crowd- 

 ed mostly leafless. Reich. Ic. Bot. t. 369. Svensk, Bot. t. 209. 

 Hook, in E. Bot. Suppl. t. 2698. 



Moist places, near Ayr, 3Ir Goldie. Fl. July. If.— This was sent to 

 me as a new species of Iittme.v by Mr Goldie. It conies, indeed, very 

 near R. crispus, but the enlarged petals are quite destitute of grains or 

 tubercles, and in this respect it agrees exactly with the true aquaticus 

 of Linn. 



5. R.*alpi/ms, L. (alpitie Dock, or MonKs Rhubarb); en- 

 larged petals cordate reticulated obscurely toothed at the margin, 

 one bearing a small grain, leaves broadly cordate ample obtuse, 

 whorls leafless crowded, flowers monoecious. — Hook, in E. Bot. 

 Suppl. t. 2694 R. cordifolins, Horn Reich. Ic. Bot. t. 487. 



Road-side from Helensburgh to the head of the Gare Loch ; and in 

 2 or 3 stations in that neighbourhood. Glen Luss. Near Dollar. One- 

 ash, Derbyshire, Mr Christy. FL July. I^.— Its root was formerly 

 employed in lieu oi Rhubarb. Leaves a span broad, cordate, very ob- 

 tuse, wrinkled and reticulated; upper ones ovato-lanceolate: whorls of 

 Jiowers very dense. 



6. R. sanguineus, L. {bloody-veined, and {i^.) green-veined Dock); 

 enlarged valves (small) oblong entire, one at least bearing a tu- 

 bercle, leaves lanceolate somewhat cordate, whorls distant on long 

 generally leafless branches. — a. leaves with bright red veins. R. 



sanguineus, L E. Bot. t. 1533. — /3. leaves with green veins. R. 



viridis, Sibth Sm. Fl. Brit. p. 390. — R. Nemolapathum, Ehrh. 



Shady pastures, woods and road-sides. — /3. far more frequent than «. 

 Fl. July. 14. . 



7. R. acutus, L. {sharp Dock); " enlarged petals oblong ob- 

 scurely toothed all tuberculated, leaves oblong-heart-shaped 

 pointed, clusters leafy." E. Bot. t. 724. 



Moist deep soils, and in watery places, not uncommon. Fl. July. If. . 

 — Much resembling var. /3. of the last species, and apjjearing to me to 

 difl'er chiefly in its leafy whorls and more coloured J^ott'e?-*. But Smith 

 says it is a totally distinct plant, and that it always grows in watery places. 



8. R. Pulcher, L. {Fiddle Dock); enlarged petals ovate deep- 

 ly toothed, one of them principally bearing a tubercle, root- 

 leaves panduriform, stem spreading. E. Bot. t. 1576.
