I wish to express my gratitude to the Director, and to the Keeper of 
the Herbarium, the Royal Botanic Gardens, Kew, for material of Carln- 
dovica and the Triuridaceae, and also to Professor Seward, F.R.S., for the 
opportunity of examining members of the latter family in the Cambridge 
Botany School Herbarium. I am indebted to Dr. Schonland of Grahams- 
town for kindly sending me leaves of Moraca polystachya and to Mr. R. Irwin 
Lynch, M.A., Curator of the Cambridge Botanic Garden, for all the rest of 
the material examined.
