152 HEXANDRIA — TRIGYNIA. [Tojiehlia. 



Pastures, way-sides, &c. Fl. Aug. If. — Stems very straggling; tchorls 

 distant, on slender leai'y branches. 



9. R. obtusifolius, L. {broad-leaved Dock) ; enlarged petals 

 ovate toothed at the base, one principally bearing a tubercle, 

 root-leaves ovato-cordate, stem ronghish. E. Hot. t. 1999. 



Way-sides and waste places, too frequent. Fl. July. 1/ . — 2 — 3 feet 

 liigli. Whorls rather close, somewhat leafy. Distinguishable by its broad 

 and obtuse radical leaves, which are generally crisped at the margin. 

 The entire terminal part of the enlarged petals or valves is, as Mr 

 Borrer observes, mostly oblong or almost ligulate. Stern scabrous be- 

 tween the elevated lines or ridges. 



10. R. maritimus, L. {golden Dock) ; enlarged petals deltoid 

 fringed with setaceous teeth and bearing grains, whorls much 

 crowded, leaves linear-lanceolate. E. Bot. t. 723. — R. aureus. 

 With. 



Marshes, principally near the sea. Fl. July, Aug. If. — Well dis- 

 tinguished from every preceding species by its narrow leaves ; excessive- 

 ly cro\^- AfiAjloicers ; bright, almost orange-coloured, enlarged jgeto/s, and 

 their setaceous, or, I might almost say, spinous teeth. 



11. R. paluslris, Sm. {yellow 3Iarsh Dock) ; enlarged petals 

 lanceolate with short setaceous teeth near the base and bearing 

 tubercles, whorls remote,leaves linear-lanceolate. E.Bot.t. 1932. 



Marshy places, remote from the sea. Fl. July. If. — Nearly allied to 

 the last, and I had an idea that it was not truly distinct: but. Sir J. E. 

 Smith considers it to be permanently different in the form of the petals, 

 when in seed, and in the number, shape, length, and situation of the teeth 

 which border them. 



** Flowers dioecious. Plants acid. (Acetosa or Sorrels.) 



12. R. Acetosa, L. {common Sorrel); enlarged petals orbi- 

 culari-cordate reticulated scarcely tuberculated, leaves oblongo- 

 sagittate. E. Bot. t. 127. 



Meadows and pastures, frequent. Fl. June, July. If 1 — 2 feet high. 



Petals becoming large, purplish, orbiculari-cordate, obtuse, membranous, 

 reticulated with veins ; tubercles very small, almost obsolete. 1 do not 

 find the enlarged petals to be ovate, as Sir J. E. Smith describes them ; 

 nor does Mr Wilson ; but orbicular and cordate. 



13. R. Acetosella, L. {S/ieeps Sorrel); enlarged petals ovate 

 not tuberculated, lower leaves lanceolato-hastate, lobes entire. 

 E. Bot. t. 1674. 



Dry pastures, frequent. Fl. May — July. If .—Variable in its height, 

 from 2 — 10 inches, and in the form of its leaves ; for, frequentl\-, only 

 the radical ones are of the shape above described, at other times many 

 of the caidine ones are so too ; the rest are lanceolate, more or less pe- 

 tiolate, entire. Every part is much smaller than the last. In very dry 

 situations and at the end of summer, the whole plant becomes of a rich 

 red colour. 



24. ToFiELDiA. Huds. Scottish Asphodel. 

 1. T. palustris, Huds. {Scottish Asp/iodel); spike ovate, stem 

 glabrous filiform nearly leafless, petals obovate obtuse, gcrmen
