ONAGRACE^E. 19 



or few, slightly drooping. Calyx-segments narrowly triangular- 

 lanceolate, acute. Petals a quarter to half as long again as the calyx- 

 segments. Stigma club-shaped. Pods moderately long, clothed with 

 curled hairs. Seeds elongate-clavate, with the testa produced at the 

 top into a small scale-like tubercle on which the coma is placed, 

 attenuate and acute below, very finely roughened with minute 

 points. Plant sub-glabrous, or with the stem, calyces, margins, and 

 midribs of the leaves clothed with short curled hairs. 



In wet places and in bogs. Common, and apparently generally 

 distributed from Cornwall to Orkney and Shetland. 



England, Scotland, Ireland. Perennial. Summer 

 and Autumn. 



Stem generally 1 to 2 feet high. Stolons at first extremely 

 slender, with the leaves remote, but later in the year shorter, with 

 the pairs of small scale-like leaves larger, and in autumn those most 

 deeply buried with a large inversely-conical bud with thick fleshy 

 imbricated scales, which at length becomes detached, and next 

 year grows into a separate plant. Leaves generally more flaccid 

 than in the two last plants, so that they commonly hang down a 

 little, very variable in size and breadth, usually entire. Buds at first 

 erect, then hanging over almost horizontally, in which position the 

 flower expands, after which the pod becomes erect. Pods 2 to 2^ 

 inches long. Seeds very diff*erent from any of the preceding, being 

 longer and narrower, and with the seed-coat extended beyond the 

 nucleus into a scale-like neck forming a continuation of the inner 

 face of the seed, upon which the coma is situated ; they are also of 

 a much lighter colour than in E. obscurum, which resembles this 

 species in habit. 



Mr. J. G. Baker has described, under the name of E. ligulatum, 

 a plant from Gormire, N.E. Yorkshire. Of this I have received 

 numerous specimens, which I have no hesitation in referring to 

 E. palustre.

 with remote pairs of yellowish scale-like leaves ; in autumn with the 

 scales much thickened and the terminal ones approximate, forming
