222 BRITISH BOTANY. 



Moist places, ditches^ etc. Perennial ; July. 



Var. yS. — Stem branchy, with four prominent lines ; leaves 

 erect, lanceolate, narrow, deeply toothed. 



E. obscurum, Schreb. — E. virgatum, Bab. An. Nat. Hist, 

 ser. 2, vol. xvii. p. 236. Fr. ? — The author of this species says, 

 "resembling E. tetragonum, but the capsule much shorter." See 

 'Manual,' in loco, 118, Florileg. Brit., %. 624. Stem 1-3 feet 

 high, with very faint lines ; scions from the lower joints not 

 ending in a rosette of leaves. Leaves lanceolate, slightly toothed, 

 not decurrent ; lower leaves tapering towards their rounded, 

 slightly denticulate base. Stigma undivided. Seeds ohlong-ob- 

 ovate, not pointed. 



Deep ditches in peat bogs. Perennial ; July, August. 



"Epilobimn obscurum, Schreb." E.parviflorum {Schreb.), Sm., 

 is our commonest species. I also take it for granted, that " E. 

 obscurum, Schreb." is synonymous with E. tetragonum (L.), Sm. 

 R. J. Lowe, on Holl's List of Madera Plants, ' Journal of Bo- 

 tany,' vol. i. p. 41. 



E. ligulatum ?, Baker. — Stem nearly two feet high, much 

 branched, quadrangular below, procumbent and creeping widely 

 at the base, sending out rootlets and stolons ; stolons numerous, 

 elongated, leafy ; at the flowering-time slender, the lower ones 

 afterwards thickened, and bearing a rosette of obovate leaves. 

 Leaves lauceolate-ligulate, varying in breadth, when narrow 

 nearly or quite entire, when broader sparingly denticulate, 

 narrowed more or less gradually to a decurrent haft (petiole?). 

 Sepals lanceolate; stigmas entire at first, finally sometimes 

 quadrifid ; seeds about half a line long, oblong-fusiform, broader 

 above. (Phytologist, n.s. vol. ii. p. 19.) 



In the same volume of the ' Phytologist,' n.s. vol. ii. pp. 366, 

 369, Mr. Babington appears to think that there is more than one 

 species included under Mr. Baker's name ligulatum, to which 

 appellation the learned author of the 'Manual of British Botany' 

 also ofifers several objections. To Mr. Babington's paper and 

 to Mr. Baker's observations or remarks on the same in the 

 April number of the ' Phytologist,' vol. ii. p. 404, those who are 

 interested in the question are referred. 



E. roseum, L., Schreb. Smooth-leaved pale Willow-herb. — 

 E.B. 693. L.c. 371. A. 2. C? Lat. 50-58°. Alt. 0-200 

 yds. Tem. 50-47°.
