Mostly like C. paniculata, but differs from it by the larger 
flowers and longer leaves. The flowers are twice as larger than 
those of C. panisulata. The plant is not represented at Kew. 
The leaves have five-nerves at the base; three of them are very 
conspicuous, while the other two are very slender.
