In the Flora Capensis. and also in the Thesaurus Capensis, this plant is de- 

 scribed as Zehneria Garcini, Stocks, but the authors had at that tiixe not seen the 

 female flowers or the fruit. It has also been known as (Bryonia Garcini and ^icyos 

 Garcini, but now that female flowers and fruit have been seen it has been placed in 

 the genus above named, the true Zahneria Garcini being a native of India and Ceylon, 

 though its name also has been changed to Blastania Garcini, (logn. The genus Tro- 

 chomeria contains about 1 5 species, one being a native of Madagascar, the remainder 

 of tropical and South Africa, and of these three T. sagiltata, T. pectinata and T. 

 Garcini have been found in Natal, though the last named appears in the " Revised 

 List of Natal Plants " and also in the " Handbook to the Flora of Natal " as T. 

 Hookeri, Harv., which is now a synonym. None of the species have any useful 

 properties so far as is known to us.
