Struthiola foliis ovato-acuminatis, concavis, imbricatis, glabris, margine ciliatis; glandulæ quatuor supra faucem.

Struthiola with oval leaves, tapering to a point, concave, tiled, smooth, and hairy at the edges; four glands upon the mouth of the blossom.

The Genus Struthiola, from the few species yet known, has been but slightly considered. Linnæus, at the end of his Generic Character, affines it to Passerina; it is true, the habits of S. virgata, and S. erecta, which are undoubtedly only varieties of the same stock, and the only two he had seen, might lead to such a comment; but, from the seven species of which we have drawings, all taken from living plants, and which will be brought forward in due course, we consider them, as perfectly distinct, in more essential characters than merely the number of chives. The acute and diligent Willdenow, in his new edition of Sp. Plant. enumerates five species from Thunberg, &c.; but from his notes of observation, prefixed to each, he had not seen either living or dried specimens of any, but the two above named. The characters in which we observe this genus to differ from Gnidia and Passerina, are, first, a cup of two leaves, constant in every species we have examined, for they cannot be considered as floral leaves, being attached to the base of the blossom, and joined together at the bottom; secondly, the honeycup forming a complete cincture to the mouth of the flower, and upon which are seated, four, or eight, upright glands. This species of Struthiola was first raised in England, at the nursery, Hammersmith, from the Cape of Good Hope, in the year 1794. It is a tender green-house plant, and very subject to be destroyed by wet; therefore, should be protected from too much rain in summer, and kept in an airy part of the house in winter. It is propagated by cuttings made in the month of May, or June, and should be planted in light, sandy peat, mixt with about one sixth part of loam. The flowers of this, as well as all the species we have seen, are extremely fragrant in the evening, beginning to smell with the setting sun, and continuing their flavour till morning. An agreeable peculiarity attendant on most plants of this natural order, and on every species of this genus, in particular, is, that they flower twice in the year, about the month of March, and again in September; in which month, last year, our drawing was made, from the Hibbertian collection, Clapham Common.

SPECIFIC CHARACTER.

Geranium foliis hispidis, multifidis; floribus heptandris; pedunculis multifloris; petala atropurpurea, margine pallido; caule suffruticoso, spithamæo.

Geranium with hairy leaves many-cleft; flowers with seven fertile chives; foot-stalk, many flowers; petals dark purple, pale at the margin; stem half shrubby, grows a span high.

This beautiful species of Geranium was raised by Mr. J. Armstrong, nurseryman of Northwarmborough, Hants, from seeds received by him, in 1796, from the Cape of Good Hope. From a branch, in fine flower, brought to us, this year, in the month of June, by Mr. Dickinson, our drawing was made; who informs us, that the ordinary treatment of common Geraniums, is all that is required for this; that it is increased by cuttings, or from a division of the root, in spring. It has not, as yet, produced any perfect seed; although it has flowered abundantly these two years, from May till October. It has something the habit of G. triste, or the Night-smelling Geranium; but differs from that species, in having a short shrubby stem, the leaves shorter and harsher, and the flowers entirely without smell.
