I. Horsfalliae ; volubilis, glaberrima ; foliis quinato-digitatis ; foliolis lanceolatis integerrimis 

 margine undulatis ; cymis dichotomis ; calycis lobis imbricatis, obtusis, sequalibus ; corolla 

 infundibuliformi : stigmate bilobo. — Hook. 



Twining, very smooth ; leaves with five finger-like divisions ; leaflets lanceolate, very entire,

 funnel-shaped ; stigma 2-lobed. Ipomoea Horsfallise. — Bot. Mag. 3315. 



This beautiful species of Ipomoea is a tender evergreen shrub, with a smooth, 

 long, twining stem. The lobes of the calyx are of a purplish-black ; the corolla 

 of a deep and splendid rose colour. The filaments of the stamens (which are 

 glabrous) are inserted upon a hairy scale or gland. The ovarium is globose, 

 seated upon and surrounded by an annular fleshy disc. The lobes of the stigma 

 are hairy. 



It was first described and figured in the Botanical Magazine by Sir William 

 Hooker, who states that " the seeds were received by Charles Horsfall, Esq., 

 either from Africa or from the East Indies, and raised by his very skilful gardener, 

 Mr. Henry Evans, at Everton, where the plants produced their lovely blossoms in 

 great profusion during the months of December and January, 1833-4, a season 

 when so gay a visitor is particularly welcome to the stove."
