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. H. Burkill, Director of the Botanic Gardens, from Pulau 
Tiuman and elsewhere, and Mr. Jr-B. Evans, of the For est 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, iti 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 GamofetalcB. 
The Leguminosce, Convolvulacece, Labiates, and a few other orders 
were described by Sir David Prain, Sonerila by Dr. Stapf, Acanthaceez 
and Gentianacece by Mr. C. B. Clarke, and the Gesneraceee by the 
author of this work, all of these were published in the Journal of 
the Asiatic Society of Bengal. The Apetalse and Gymnosperms, 
exclusive of the Euphorbiacece and the Urticaceee, 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 King, 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. fit. F.B.l. 
The letters l.c. after a reference signify the last quotation of the 
work [locus citatus ) referred to, thus : Clarke, F.B.I. l.c. 27 signifies 
C. B. Clarke in Hooker’s “ Flora of British India,” volume (last 
quoted), page 27.
