CONTRIBUTIONS 



TO THE 



Flora of Siam. 



MONOCOTYLEDONES. 



The present contribution, dealing with the Monocotyledones and 

 Gymnosperms with the exception of the Family Orchidaceae, which 

 is reserved for a separate paper, is continued on exactly the same 

 lines as the earlier papers dealing with the Dicotyledones. 



Just before the publication of the first contribution — the 

 Polypetalae — there appeared in Bot. Centralbl., Beihefte 

 xxvii. 2, pp. 455-507, a paper by C C. Hosseus entitled " Beitrage 

 zur Flora Siams," and before the publication of the second con- 

 tribution — the Gamopetalae and Incompletae — there appeared in the 

 same publication (vol. xxviii. 2, pp. 357-457) a paper entitled "Die 

 botanischen Ergebnisse meiner Expedition nach Siam " by the 

 same author. In the following enumeration these papers are cited 

 briefly Hosseus i. and Hosseus ii., respectively.
