The Cortusa-leaved Geranium is a tender plant, seldom growing to more than a foot in height; producing its blossoms, which are extremely fragrant, in erect bunches, from the summit of the branches, and must be protected, through the depth of winter, in the hothouse. The propagation is both slow and difficult, as it rarely perfects any seeds, and forms but few branches. The cuttings when taken off, which ought to be done about the end of May, should be exposed to the sun, till the part where cut has formed a tough coat over the wound, which will take place in two or three days; when they will not be so subject to rot from the moisture of the earth, as if planted when just taken from the plant. These instructions are necessary to be observed, in the propagation of all the thick-stemmed Geraniums, by cuttings. A mixture of sandy peat, with a small quantity of old rotten dung, will prove the best compost for preserving this plant. Our drawing was taken this year, in July, at the Hammersmith nursery. A mistake has arisen with regard to the name of this species of Geranium; which was evidently not known to any botanist, antecedent to its being brought to England in 1786 by Mr. A. Hove, a native of Poland, from the south west coast of Africa, and found by him in about the 23d degree of south latitude. Professor Martyn, in his new edition of Miller’s Dictionary, article Pelargonium 43, has taken for granted that this is the plant designed by Professor Jacquin, where he treats of G. cortusæfolium; giving the G. tabulare of Burman, Linnæus, &c. as synonymous to it; but undoubtedly, no such intention could be in the Professor, as the uniting these two plants, which are so entirely dissimilar; but only an unfortunate inclination to alter an old established name, for one, which he conceived more appropriate to a well known, common species; whence the confusion; the constant consequence of such useless alterations, whether generic or specific.[Pg 491]
