167. Fracaria

(620.) F. Virginiana, Duch., var. Illinoensis, Gray.

Of all the specimens of this species in our collection, only one collected at Ottawa, Ont., by J. M. Macoun can be referred here. Collectors in western Ontario should look out for it.

(717.) T. Menziesii, Torr. & Gray; Macoun, Cat. I., 155.

180. Tiarella

(3107.) T. laciniata, Hook., Fl. I, 239; Torr. & Gray, Fl. I, 588.

This species is included in T. trifoliata in Watson's Index of the Polypetalae, but specimens collected on Vancouver Island two years ago satisfy me that they are distinct. They differ as much in habit as in appearance, for while one is at home in the rich woods near the sea, the other is found only on stones in mountain brooks. Besides being laciniate, the leaves are smaller and thinner, of a brighter green, and more delicate in every way. On stones in mountain brooks flowing from Mount Arrowsmith, Vancouver Island. Alt. 2000 feet. 1887. (Macoun.)

189. Sedum

(3108.) S. Oreganum, Nutt.; Torr. & Gray, Fl. I, 559.

Abundant on rocks on a small islet at the head of Horno Lake; also on mounts Mark and Arrowsmith, Vancouver Island, 1887. (Macoun.)

192. Myriophyllum

(3109.) M. alternifolium, DC.

Julianshaab, Greenland. (Rosenvinge.) Lake Memphamagog, Que. July, 1886. (Dean, vide Morong.)
