INTRODUCTION. XIX 



Linnean Society and of the Federated States Museums. The genus 

 Klossia and very many species are associated by name with these 

 energetic collectors. Other plants have been contributed by 

 Mr. J. H. BuRKiLL, Director of the Botanic Gardens, from Pulau 

 Tinman and elsewhere, and Mr. J. C. Evans, of the Forest Depart- 

 ment of the Federated Malay States, sent plants from Pahang, and 

 Mr. F. W. Foxworthy, of the Forest Department, sent a large 

 series from the Malay States. 



Literature, etc. — To save space, references are only given to 

 certain works, viz. the references to the original description of 

 the species, references to King's " Materials for a Flora of the 

 Malay Peninsula," and the " Annals of the Botanic Gardens, 

 Calcutta," and to Hooker's " Flora of British India," which work 

 contained all the species known in the Malay Peninsula at the date 

 it was written. References are also given to good figures of the plants 

 described. 



The works mentioned give a full series of references from other 

 works, as well as the synonyms which, unless necessary, are also 

 excluded. King's " Materials " were published in the Journal of 

 the Asiatic Society of Bengal, in different volumes, between the years 

 1889 and 1908, when he died, and Mr. J. S. Gamble continued the 

 work, he previously having assisted Dr. King in some of the orders 

 of GamopetalcB. 



The Leguminosce, ConvolvulacecB, Labiates, and a few other orders 

 were described by Sir David Prain, Sonerila by Dr. Stapf, Acanthacece 

 and GentianacecB by Mr. C. B. Clarke, and the Gesneracece by the 

 author of this work, all of these were published in the Journal of 

 the Asiatic Society of Bengal. The Apetalae and Gymnosperms, 

 exclusive of the Euphorbiacece and the Urticacece, were described by 

 Mr. Gamble in the Journal of the Asiatic Society of Bengal. The 

 Monocotyledons were described by the author in three volumes 

 independently under the title of " Materials for a Flora of the Malay 

 Peninsula. Monocotyledons by H. N. Ridley, Singapore, 1907 to 

 1908." 



The separate copies of King's and Gamble's " Materials " were 

 paginated twice : on the top of the page is the pagination of the 

 original article in the Journal, at the bottom of the page is the 

 pagination of the " Materials " as a separate work. As the separate 

 issue is rare and out of print, I have quoted the original pagination 

 of the Journal. This is quoted as Ki7ig, Journ. As. Soc. Beng., the 

 volume being given at the commencement of an Order or series of 

 Orders. 



Hooker's " Flora of British India " is quoted as Hook. fil. F.B.L 



The letters I.e. after a reference signify the last quotation of the 

 work {locus citatus) referred to, thus : Clarke, F.B.L I.e. 27 signifies 

 C. B. Clarke in Hooker's " Flora of British India," volume (last 

 quoted), page 27.
