described by J. Mueller in Martius’ Flora Brasiliensis (xi., pt. ii.,

full description, with a plate, from a plant growing in the Ceylon 
nic ens, was contributed by the late Dr. Trimen to the 
Journal of Botany (1880, pp. 321-325, t. 219). This plate was 
reproduced in the Kew Report (1880, p. 17).
