156 ENGLISH BOTANY. 



rescence. Lower leaves withering before the flowers expand, and 

 as well as the middle ones, pinnatifid, with a narrow undivided strip 

 on each side of the midrib, and a few long distant divaricate or 

 falcate lobes with their length greater than their breadth on each 

 side ; terminal lobe deltoid, acuminate or hastate ; upper leaves 

 strapshaped, undivided, with rather long acute spreading auricles, 

 all quite flat and repand-denticulate or entire, with projecting 

 callous points. Anthodes numerous in a compound umbellate 

 corymb. Peduncles and phyllaries thickly clothed with rather 

 short olive-green gland-tipped hairs, very rarely glabrous. Achenes 

 prismatical, very slightly compressed, with 4 of the ribs much 

 larger tban the others ; the ribs indistinctly transversely rugose. 



In marshes, by the sides of tidal rivers, and in fens. Very rare. 

 It has occurred in Kent, Essex, Suffolk, Norfolk, Cambridge, and 

 Hants ; but I am not aware that it is to be found now (1865). 

 except among beds of reeds on the banks of the Thames behind 

 Plumstead Butts, immediately below Woolwich, where it was 

 rediscovered a few years ago by Mr. A. Irvine. 



England. Perennial. Early Autumn. 



Kootstock producing short thick fleshy subterranean shoots, 

 terminated by closed huds rising vertically close together, so that 

 the roots do not spread over the ground. Stem 3 to 7 feet high, 

 with a very large hoUow in the centre, angular, from the midrib 

 of the leaves being decurrent. Leaves very numerous, the lower 

 ones soon withering, those on the middle of the stem and above 

 it with few lateral lobes, but these, when present, are long and 

 narrow and project abruptly beyond the general outline of the leaf; 

 auricles very acute. Peduncles elongate, produced so nearly from 

 one point, that the inflorescence at first sight appears to be a 

 compound umbel, the outside branches longer than the inner. 

 Anthodes f to 1 inch across. Plorets pale-yellow. Achenes pale 

 fawn-colour, quadrangular fx'om the prominence of 4 of the ribs. 

 Pa2)pus silky, but sliglitly exceeding the pliyllaries. 



A very distinct species, which can never be mistaken when it 

 has once been seen, differing from the other British species in the 

 same way that the Accipitriua group of tlie genus Uieracium does 

 from the Pulmonarea section ; but the large marsh form of S.arvensis 

 has been frequently recorded for it by persons unacquainted with 

 S. palustris. The stem of the latter is perfectly straight, much 

 stouter in proportion to its height, with the central hollow greater. 

 The leaves are narrower, much more gradually and more acutely 

 pointed, and the lobes in the lower ones project abruptly from the 

 general outline of the leaf; all the leaves have the margins flat and
