the same year, but it does not seem to have lived long. He also 
planted several in his garden in Zanzibar, and some of his 
observations on the generation of heat in male cones of cycads 
(K.B., 1914, p. 390) were made on these. The following reference 
in a letter of March 5th, 1879, is probably to one of them: ‘‘I © 
have a splendid Cycas Thouarsii 12 ft, hivh in lovely foliage 
at my country place.’’ This note shows that he had at last 
obtained the identification of the ptant. 
The history, taxonomic status, nomenclature and distribution 
of the species is to some extent obscure, and it may be useful to

interrogation and the apposition ‘‘ Indix orientalis,’’ are added 
to the name*. This species and C. angulata are compared with 
C. circinalis ‘‘ vera,” and certain differences in the structure 
of the seed are pointed out. On the same page under Cycas the 
author, before passing on to the Australian species, says: ‘‘ Sub 
nomine Cycadis circinalis plures species procul dubio confusae, 
e vivis solummod extricandae. Duae in India (p. 348) orientali 
proveniunt, quarum altera Cycas circinalis vera, €X synonymo
