PASSION-FLOWER with leaves two-lobed: lobes oblong and straddling, dotted beneath, and glaucous: segments of the cup linear. Native of the Caribbee Islands. REFERENCE TO THE PLATE. 1. A flower spread open. The most graceful ornament to the hot-stove is the elegant and favourite genus Passiflora, whose branches meandering against the interior sides of the building adorn it to the greatest advantage. From a branch of the Passiflora perfoliata thus situated in the collection of the Countess de Vandes our drawing was taken. The only coloured figure of it we have seen in the Hortus Schœnbrunnensis of Jacquin. It flowers in great luxuriance during the months of July and August. [Illustration] PLATE DXLVIII.
