have been imported from Japan, and may therefore probably bear cul- 

 tivation, at least against a wall, in the open air, but this we have not 

 yet ascertained. Our specimen flowered freely in the greenhouse for 

 the first time in April 1841, and continued in blossom for a long time.

Description. — Stem slender, woody, branched, twining, having adpressed 

 pubescence. Leaves (2\ inches long, -J inch broad) nearly sessile, 

 scattered, spreading, green, paler behind, covered tn both sides with 

 long subappressed somewhat deciduous hairs, the upper lanceolato- 

 clliptical entire, the lower spathulate incise-serrated ; midrib chan- 

 nelled in front, prominent behind, veins oblique, seen chiefly behind, 

 slightly reticulated. Stipules none. Peduncles solitary, opposite to 

 the upper leaf, elongated, erect, urabollato-cymose, many-flowered, 

 slightly covered with adpressed pubescence, pedicels rather shorter 

 than the peduncles, several of them simple, others irregularly divided, 

 erect, slender, swelling a little at the apex. Bracts placed at the ori- 

 gin of the pedicels, subulate, hairy, reflexed, caducous. Flowers erect, 

 irregular. Calyx 5-sepalous, sepals resembling the bracts, imbricated, 

 subequal, linear-subulate, diverging at the apices, green, covered on 

 the outside with long spreading hairs, deciduous. Corolla irregular, 

 lilac, paler on the outside, pentapetalous, hypogynous, glabrous, alter- 

 nating with the sepals, imequal, the lowest the longest, each striated 

 with three nerves behind, imbricated ; claws converging into a tube, 

 edges inflected ; limb spreading, slightly reflexed, laminaj spathulato- 

 lanceolate, apiculate, 4 of them ascending, the whole of the lower 

 half of the two upper, and generally half the breadth of the lower half 

 of the two next, sprinkled on the inside with oblong dark lilac spots. 

 Stamens 5, all fertile, alternate with the petals, and half as long as 

 them, hypogynous ; filaments nearly colourless, ascending, glabrous, 

 swelling a little in their lower half, channelled on both sides, the 

 lowest the longest ; anthers dark lilac, bilocular, reflected at the apex, 

 lobes diverging at the base, attached in the sinus, bursting by two 

 elongated slits, which finally extend along the front to the base of the 

 lobes ; pollen granules oblong, of dark lilac colour. Pistil shorter 

 than the stamens, nearly straight; stigma minute, of two at length 

 spreading teeth ; style subulate, scarcely ascending ; germen green, 

 oblong, glabrous, shorter than the calyx, slightly furrowed on two 

 sides, bilocular, raised on a short tumid footstalk. Ovules numerous, 

 ovato-kidney-shapcd, attached in the sinus by a short cord to an in- 

 conspicuous central placenta. 

 This very curious and interesting plant flowered in the stove of Mr Cun- 

 ningham's nursery. Comely Bank, in March 1841, I believe for the 

 first time in Britain, and very soon after it flowered in the greenhouse 

 of the Royal Botanic Garden. These were weak specimens, and nei- 

 ther from them, nor from the Berlin figure quoted above, could I have 

 had any idea of the beauty of the species. The specimen in Sir Wil- 

 liam Hooker's Herbnrium, however, from which in part the figure in 

 the Botanical Magazine was taken, shews how very ornamental the
