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 singular and well marked species, evidently
allied to S. diapensioides and S. cæsia, 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 different
species from the true plant.

S. ceespitosa, which was described as a native of Melville Island, by Mr. Brown, and who, indeed, has
expressed the same opinion.

Captain Sabine.—We refrain from quoting many synonyms under this and the following species of Saxi-
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 words. 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 colour, which appearance is well represented in Gunner’s figures, above quoted.

agrees with our Europaean specimens of this plant, and we have, under the preceding species, mentioned how
difficult it is to distinguish the two.

Cham, in Herb, nostr.
H ah. Behring’s Straits. A. Menzies, Esq.—This species differs considerably from any with which we
are acquainted. . Its inflorescence a good deal resembles that of S. hypnoides, but its foliage is quite peculiar,
being extremely harsh and rigid, shining as if varnished, and at the same time sparingly clothed with
apparently viscid hairs. We had called this S. vemicosa in our own manuscript, but having received specimens
of the single-flowered state under the name of S. sileniflora, we gladly adopt the name, though it does
not appear to be any where published. It has indeed been referred incorrectly, in the Botany of Captain
Beechey’s Voyage, to S. ceespitosa.
