520. H. Lindbergh. Mitt. Jour, of Bot. I., p. 123. (H. pratense, Bry. Brit. 399.) “St. sparingly branched in an irregular manner, without any appearance of becoming pinnate; l. loosely compressed ovate or ovate-lanceolate, acute, but with a broad point,[^[2]] margins entire, nerveless; cells at angles enlarged and pale; caps., according to Lindberg, is on a rather thick seta 1in. long, turgid ovate, when dry plicate.”

[2]. Some of the leaves, even on authenticated specimens, have longer and narrower points (acuminate), but in no case that I have seen are they denticulate.

“Damp sandy ground among thin grass, not in bogs. The fr. has been gathered once by Dr. Klingraff in June, in W. Prussia.”

“H. pratense differs from above in its irregularly pinnate stems, more compressed foliage, l. lanceolate with a narrow point denticulate at apex, and the enlarged basal cells of same colour; not found in Britain.”

521. H. arcuatum. Lindb. (H. pratense, var. β. Bry. Brit.) “L. more falcato-secund, scarcely complanate.”

Clay soils, common.
