244 SAXIFRAGEiE. [Saxifraga. 



Hab. Cape Newnliam. David Nelson. Behrlng's Straits. Mr. Meiizies, Uiialasclika. Chamisso, — 

 This species has had the misfortune to receive various names, and, indeed, to the above list may be added 

 S. diapensioides of Fischer, according to Mr. Seringe. It is a sin^lar and Avell marked species, evidently 

 allied to S. diapensioides and S. ccesiUf wanting, however, altogether, the remarkable glaucous incrustation 

 of those species, and being destitute of pores. The flowers, too, are totally different ; solitary upon the 

 extremity of a slender few-leaved glandular stalk, large in proportion to the size of the plant, and apparently 

 of a yellow colour. The calyx is wholly inferior, the petals broad, with three strong nerves, of which the 

 lateral ones are sometimes branched.

Hab. North-West coast of America. David Nelson, — We insert this upon the authority of Mr. Pursh, 

 who, indeed, quotes the figure of Jacquin with a mark of doubt, so that it is in all probability a very differ- 

 ent species from the true plant.

Hab. Melville Island. Lieutenant Hopner. — We fear this will prove to be the variety unijiora of 

 S. ccBspitosa, which was described as a native of Melville Island, by Mr. Broivn, and who, indeed, has 

 expressed the same opinion.

 Captain Sabine. — We refrain from quoting many synonyms under this and the foUoM ing species of Suxi- 

 fraga^ because of the great difficulty of ascertaining them correctly. Though we believe them to be truly 

 distinct, and though they are readily distinguished by the eye, yet it seems hardly possible to define their 

 characters in Mords. The present has a stouter habit than S. exarata; the leaves are broader, and, 

 what appears to us the most constant character, the flowers (fewer in number) are of a much larger size. 

 In almost all our specimens the upper part of the stem, and especially the calyx, assume a dark purple or 

 frequently sooty colourj Avhich appearance is well represented in Gunner's figures, above quoted.
