This Jpomoea, attractive both in foliage and in flowers, 
the latter being of a colour very unusual in the genus, 
has long been known in gardens. Its first recorded | 
appearance was in the Calcutta Botanic Garden in 1812, 
where, according to Roxburgh, it sprang up accidentally 
amongst plants received from friends in the vicinity of 
Calcutta ; of its native place he was uncertain. Under 
the name of J. tuberculata it was figured and described in 
the Botanical Register in 1816, and it is there stated that 
the plant was raised from seeds collected in the Calcutta 
Botanic Garden, and sent by Sir Evan Nepean, it would 
appear early in 1815, to Messrs. Whitley, Milne and Brame, 
Nurserymen of King’s Road, Chelsea. Jacquin first met 
with it in the Vienna University Botanic Garden, where, 
he informs us, it was obtained amongst several unnamed 
Chinese seeds received from England in 1814. The 
species appears to have a wide distribution, but very 
probably it is not a native in some of the localities from 
which it is recorded. In India it is known from Simla, 
Rohilcund and the Deccan Peninsula. It is also known 
from Ceylon “in dry country, very rare,” and from 
Java. There is no satisfactory evidence that it is 
native in China and Australia, though these countries 
are included in its range by various authorities. In 
Tropical Africa it ranges from Nubia, Abyssinia, the 
Egyptian Sudan, German East Africa to the Kwebe 
Hills in Ngamiland, and Upingtonia in South-West 
Tropical Africa. There is a very small-flowered speci- 
men in the Kew Herbarium labelled, possibly incorrectly, 
“C.B.S. Villette.” The material for the accompanying 
figure was obtained from a plant raised from seeds 
received in 1917 from Major Howard of Richmond, and 
collected by him at Kilimatinde in German East Africa. 
The flowers vary considerably in size as shown by the 
plant cultivated at Kew, as well as by the dried speci- 
mens, and forms with unusually large flowers have been 
supposed to represent distinct species and have been 
described as such. It is possible also that the colour 
varies, for in one instance the flowers are said to be 
white. The curious little pouches, sometimes very 
conspicuous at the base of the outer sepals, appear to 
differ in size and in some of the dried specimens are
