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.

Clematis Leeana, Auct. (?)
Eine kräftig wüchsige, harte, windende Pflanze, immer grün, mit dicken, dunkelgrünen Blättern. Auf einem violets ten Stiele erscheint die weiße Blume, mit linienförmigen, ohngefähr 2/3 Zoll langen Sepalen, und mit einem seidenartigen Büschel unfruchtbarer Staubfäden in der Mitte. Sie gehört zur Gruppe C. Flammula, trägt einzelne Blüthen aus den Zweigachseln, aber deren sehr viele gleichzeitig, was sie zu einem schäßenswerthen Schmucke der gemäßigten und falten Häuser erhebt.

Translation:
Clematis Leeana, Auct. (?)
A vigorous, hard, twining plant, always green, with thick, dark green leaves. On a purple stem appears the white flower, with linear sepals about 2/3 inches long, and with a silk-like tuft of sterile stamens in the middle. It belongs to the group C. Flammula, bears single flowers from the branch axils, but many of them at the same time, which makes it a dreadful ornament of the temperate and folded houses.
