The native place of the Verbena mutabilis seems rather enveloped in obscurity: by some it is supposed to be indigenous to Peru. It is a beautiful plant, and the most desirable Verbena we are acquainted with, as it is at least six months in successive bloom. It is one of those Verbenas that, differing a little from the general character of that genus, has received various titles from different botanists: by Professor Vahl, in his Enumeratio Plantarum, it is called Stachytarpheta. The present species has been recently figured in the Paradisus Londinensis under the title of Cymburus mutabilis, and probably at some future period it may again receive another title: but until we can find some better path to lead us into the open plain or Information, we shall keep jogging on in the old beaten track, in preference to every crooked turning that may bewilder us into the mazy labyrinth of affected Science. Our figure was made from a fine plant in the nursery of Messrs. Colville. [Illustration] PLATE CCCCXXXVI. CORRÆA VIRIDIFLORA. _Green-flowered Corræa._ CLASS VIII. ORDER I. _OCTANDRIA MONOGYNIA._ Eight Chives. One Pointal. ESSENTIAL GENERIC CHARACTER. CALYX monophyllus, quadri-dentatus. Corolla petala quatuor. Stamina octo. Germen superum. Capsula quadrilocularis. Semina quatuor. EMPALEMENT one-leafed, four-toothed. Blossom four-petalled. Eight chives. Seed-bud above. Capsule four cells, and four seeds. SPECIFIC CHARACTER. CORRÆA, foliis oblongis, oppositis, undulatis, stellatim hirsutis, supra viridibus, subtus ferrugineis: foliis junioribus conniventibus, flores dum parvos obscurantibus, qui postea emergunt ex axillis foliorum, et dependent. Corolla viridis, leviter punctata, petalis adhærentibus in forma cylindrica. Rami oppositi, ferruginei. CORRÆA, with oblong opposite leaves, waved, and beset with divers starlike specks; green on the upper surface and rusty beneath: the younger leaves connive together, and obscure the flowers when young, which afterwards emerge from the axillæ of the leaves, and hang down. Blossom green, and lightly dotted, the petals adhering in the form of a tube. The branches are opposite, and rusty. REFERENCE TO THE PLATE. 1. The empalement. 2. A blossom detached from the cup. 3.
