T. primulina, Hemsl. 
Thunbergia, including Hezacentris (B. M., t. 4786), and 
Meyenia (B. M. t. 5013), presents great variety in habit 
and in the shape, size and colour of the flowers. About 
ninety species have been described; out of which upwards 
_ of fifty-five are peculiar to tropical Africa. The present 
species is only known from the cultivated plant raised 
from seed presented to Kew last year by Sir John Kirk, 
who collected it on the main escarpment of the Uganda 
Railway, at an elevation of 8,000 feet. ee : 
The plant figured flowered in a greenhouse in August 
of last year, and promises to develop into a very orna- 
mental subject for a cool house; but its value can hardly 
be estimated from a young specimen flowering for the 
first time. Apart from the tube of the corolla, the 
flowers are singularly like those of the common primrose, 
both in colour and shape. In general appearance it closely 
resembles the extratropical South African T. atriplicifolia, 
Mey., and it was provisionally given that name. 5 
Among other ornamental species previously figured in 
the Magazine, we may note the old favourite 7’. alata 
(t. 2591 and 8512); 7. grandiflora (t. 2366) ; T. laurifolia 
Aveusr Ist, 1901. }
