Hab. By the R. Meklong, 1867 (Pierre, n. 3229, in Herb. Kew.). 



It is not clear why Engler and Prantl have substituted « Illipe » for the name 

 of this genus. The original référence for the genus Bassia is Koenig, in L., Mant. 

 Plant, app. p. 555. Engler and Prantl quote for « Illipe » pp. 555, 563, of the 

 same work, published in 1771. On turning to the Appendix we find that there 

 is no such name as « Illipe » mentioned in the detailed description of the genus 

 by Koenig on p. 555. On p. 563, where Kœnig further describes the species 

 Bassia longifolia, he simply cites as a synonym his own « Illippe Malabarorum 

 mss ». The wrongly spelled form of the name « Illipe » was taken up by F. von 

 Mueller in 1884, without any obvious reason; and why Engler and Prantl hâve 

 adopted it is a puzzle.

(by Sir George King) 



Through the kindness of Sir George King, which I gratefully acknowledge, 

 the account of the Siamese species of Ebenaceae is taken from his manuscript 

 continuation of « Material for a Flora of the Malay Peninsula », the succeeding 

 instalments of which will be printed and published in due course. Ail that 



1 hâve done is to render the English descriptions into Latin. I hâve not even 

 seen the plants. In the list of Schomburgk's plants in Herb. Kew. is an undeter- 

 mined species of Diospyros (n. 115) from the neighbourhood of Bangkok, but 

 the spécimen of the flowering twig collected was not kept.
