The names of some few species which occur in garden catalogues are omitted from amongst the foregoing descriptions, in consequence of the plants they represent being quite unknown to us, having, as we suppose, passed out of cultivation. We particularly refer to C. biternata (white), C. chinensis (dull purple) , C. dahurica ( dull purple) , C. japonica (purple), C. terniflora (white), and C. triternata (white) . It may, we think, be safely assumed that they are unimportant as garden plants. One or two others, as C. Gebleriana (soongarica) and C. jubata, are essentially weedy in character ; while of some few which occur in the Continental trade lists, as C. Blackburniana, C. californica, C. Camusetii, C. indica, and C. Leeana, we have been unable to obtain any reliable information. C. nepalensis, another cataogue name, appears to be applied to C. montana in some plant lists.

RANUNCULA'CEÆ.- Clématis califórnica? A species apparently related to C. flórida.

CLEMATIS califórnica. Probably a new species, but a very doubtful name, as I cannot find any such name in Douglas's Californian Herbarium, or amongst any of his memorandums; nor is any such name to be found in Steudel's Nomenclator, or in any other modern catalogue that I have access to: therefore, I think it very doubtful; for generally when a plant is named after a country, it either is the most common in that country or very plentiful there.
