tate, and each graniferous. Are these sufficient marks to distinguish 

 it from R. sanguineus? 



5. R. pulchvr (Fiddle Dock), valves oblong toothed one of 

 them principally bearing a grain, radical leaves panduriform, 

 stem smooth diffuse. Light f. p. 189. E. B. t. 1576. 



HAB. Way-sides in dry places, Sibbald. Fl. July. 7/ . 

 Stems very straggling. Whorls small, distant, leafy. 



6. R. oitusijolius (broad leaved Dock), valves ovate toothed 

 one principally bearing a grain, radical leaves ovato-cordate 

 obtuse, stem ronghish. Ldghtf, p. 189. E. B. t. 1999. 



HAH. Way-sides and waste places, frequent. Fl. July. 7/. 



Two to three feet high. Whorls rather close, somewhat leafy. Di- 

 stinguished by its broad and large radical leaves, which are generally 

 crisped at the margin. Stem scabrous between the elevated lines 

 which form the striae. 



7. R. maritimiis (golden Dock), valves deltoid fringed with se- 

 taceous teeth-bearing grains, leaves linear-lanceolate, whorls 

 much crowded. E. B. t. 725. 



HAB. Marshes principally near the sea. Fl. July, Aug. ")/ . 



Well distinguished from every preceding species by its narrow leaves, 

 and singularly setaceo-spinous, excessively crowded, and bright 

 coloured valves. Lightfoot's R. maritimus seems rather to belong 

 to the next species. 



8. R. palustris (yellow Marsh Dock), valves lanceolate with 

 short setaceous teeth near the base bearing grains, leaves linear- 

 lanceolate, whorls distant. Lightf. p. 188 (R. Jttarittrttxs) . 

 E.B. M932. 



HAB. Marshes. Angus-shire, G.Don. Fl. July. T/. 



I fear that future observations will prove this to be but a var. of 



R. maritimus, with more distant whorls of fewer flowers, less bright 



coloured valves, with shorter setaceous teeth. 



** Flowers dioecious, inner enlarged valves of the perianth without 

 any tubercle or grain. (Acctosa or Sorrels.) 



9. R. Acetosa (common Sorrel), leaves oblongo-sagittate their 

 segments bent towards the petiole. Lightf. p. 191. E. B. 

 t. 127. 



HAB. Meadows and pastures, common. Fl. June. 1{. 

 One foot to two feet high. Valves large, purplish, cordate, obtuse, mem- 

 branous, reticulated with veins j without grains in my specimens. 



10. R. acetoseUa (Sheep's Sorrel), leaves lanceolato-hastate 

 their acute lobes spreading or even recurved. Ligh/f. p. 191. 

 E. B.t. 16/4. 



HAB. Dry pastures, frequent. Fl. May July. 71 . 



Variable in size, which is from 2 10 inches, and in the leaves; for 

 sometimes only the radical ones are of the shape above described, 

 at other times many of the cauline ones are so too ; the rest are
