 its slightly perigyaous stamens and petals. This insertion, however, equally exists in some acknow-

Hab. Canada. Goldie. Lake Huron. Dr, Todd. Woody country from lat. 54° to 64°. The speci- 

 mens, here noticed, were gathered at Cumberland House Fort and English River, by Dr. Richardson and 

 Drummond. Unalaschka. C/iamisso. On the Columbia. Dr. Scmler ; Douglas. — After the elaborate and 

 faithful description which Dr. Richardson has given of this plant in the Appendix to the Second Edition of 

 Franklin's Journal, it might be needless for me to offer any farther remark, were it not that, like others 

 of this perplexing genus, it is liable to variation, and it will be seen by the above synonymy what diffi- 

 culty the American Botanists have found in determining its place. Dr. Richardson has included among his 

 references the Spergulastrum lanceolatum of Mich., which, nevertheless, I have ventured to keep distinct; 

 but I am far from saying that they ought not to be united, different as the extremes may appear to be. Indeed 

 my specimens of S. longifolia, from Dr, Boott, (which are the same as Professor Bigelow's,) and others 

 from Dr. Torrey, have rather broader leaves than Dr. Richardson's plants, and quite smooth (not scab- 

 rous) stems and margins to the leaves: thus, as it were, partaking of the characters of the following 

 species. With regard to the genus Spergulastrum or Micropetalum, all the American Botanists concur in 

 uniting it with Stellaria, the minute or absent petals being a very unimportant character, and decidedly 

 variable in the species of the genus in question. The stamens and petals are perigynous, as in Larbrea.
