Hab. «. Labrador. Dr. Morrison. /?. Throughout Canada, and as far north as lat. 64°, and among the 

 Prairies of the Rocky Mountains. Dr. Richardson, Drummond. — Amongst several plants sent by Mr. Dnim- 

 mond, only the var. /3. was found, distinguislxed from the pnmary fonn by its much smaller, almost 

 white flowers and simple stem, but which is also seen in Northern Germany, in turfy soil, with all the 

 intermediate transitions. E. davuricum, Fisch. (De Cand. Prodr. v. 3. p. 42,) appertains to this variety. 

 — The var./3. corresponds with the E. palustre of Dr. Richardson, and is sometimes branched, when it is 

 identical with the E. lineare of Muhl. Cat. and of Bigelow, which De CandoUe refers to E. squamatum,
