Cuntivation.—Didymocarpus cyanea was first grown at 
Kew in 1902, when seeds of it were received from Mr. 
C. Curtis, Superintendent, Botanic Gardens, Penang. It 
has also been received from Professor Costantin, Jardin des - 
Plantes, Paris. It flowers in the autumn, the pretty dark 
blue flowers opening in slow succession in a tropical house, 
where it receives the same treatment as Sinningia and the 
Streptocarpi. Although the Malayan species of this genus 
have been again and again tried as garden plants at Kew, 
they have never been a success. Probably they require to 
be treated as annuals, and as they do not mature seeds 
under cultivation, they soon die out. They are quite as 
pretty as their allies the Streptocarpi, which were at one 
time generically united with them, S. Reaii having been 
figured in this work, t. 3005 (1830), as Didymocarpus Rezii, 
while D. malayana, B. M. t. 7526, has all the appearance of 
a yellow flowered Streptocarpus.—W. Watson.
