Like the other species, C. convolvulacea is confined to 
Kastern Asia, but its area of distribution within the region 
is somewhat wide, for it extends from the Shan Plateau in 
Central Indo-China northwards into Yunnan and Szechuan 
and thence westward into Central Tibet; the flowers in 
Tibetan examples are smaller than in the Chinese and Shan 
specimens, but do not materially differ in other respects. 
Extensive as the area from which specimens have been 
reported actually is, it seems possible that it may prove to 
be wider than these indicate. The plant from which our 
figure was prepared was presented to Kew by Mr. M. 
Leichtlin of Baden-Baden in 1906 and flowered here in 
August, 1907. Its flowers were larger than those of 
Burmese specimens and than those of all the Chinese speci- 
mens except in a single gathering communicated by Mr. A. 
Hosie from between Batang and Tachienlu, and thus 
differed as much from these, in a converse direction, as the 
flowers of Tibetan specimens do. But, like the Tibetan 
ones, they agree with the Chinese and Burmese flowers in 
every character save that of size. 
When Mr. Leichtlin sent this plant to Kew he suggested 
that it might be a Campanulaceous species new to cultivation, 
but added no note as to its origin. With a plant sent by 
him at the same time to Mr. H. J. Elwes, in whose collection 
at Colesborne it flowered contemporaneously with the plant 
at Kew, Mr. Leichtlin gave a locality in the North-West 
Himalaya. In response to a request for more definite 
information, Mr. Leichtlin has most obligingly stated that 
these plants were derived from seeds communicated to him 
by the late Mr. W. Gollan, Superintendent of the Botanic 
Garden at Saharanpur in Northern India ; these seeds were 
obtained in the North-West Himalaya by one of Mr. 
Gollan’s native collectors. Hitherto no Indian botanist has 
communicated herbarium specimens of C. convolvulacea 
from any portion of the Himalaya, but, when regard is had 
to the care which characterises the work of Mr, Leichtlin 
and characterised that of Mr. Gollan, the possibility that 
C. convolvulacea may occur in the North-West Himalaya 
should not be overlooked by botanical travellers,
