Dr, Furtado*8 botanical work . 
Dr. Purtodo spent the main part of his time continuing his study of 
the firenus Calamua . which contains the majority of commercial ratt ans . 
This is a large genus, including some TCT'specTes 'in Malaya' alone , and 
past publications upon it have been much confused, so that a new account, 
based on a thorough study of many specimens, is much needed. Mrj!,..Cprner 
and Dr. Purtado have in the pust few years gathered much new material, 
anS this is proving 6T great^ value In tbe^ present work. 
t 
During the month Dr. Purtado sorted over all specimens of the genus 
into groups, and studied especially Calamus javensis (of which he dis- 
tinguished and described 8 varieties) and six other species, two of which 
prove to be new; comparative descriptions of these, and critical notes 
on other species incidentally examined, have been prepared. It is esti- 
mated that a preliminary survey of the genus in Malaya, based on material 
now in hand, would occupy six months, after which a comparison with type 
material from Buitenzorg and elsewhere v/ould be necessary for a final 
corapletion of the work. As the rattans a re an importan t produc t of the 
country, and no comparative account of them exists UiiJ work Ts of c on- 
siaei'abie importance and its completion is much to be desired. 
During the month also Dr. Purtado, completed the text of two paper s 
on local vegetabl es, one on the species and varieties of Aroaranthus 
(Bay^'^~grown ' , and one on the edible Aroids (Keladis etc.). A 
number of illustrations for both these p apers have been, p repared by. th^ 
Artist; a few more are needed to conplele the number required. Both theB< 
piaper s" will be very useful, as no fu ll studies of these plants as^growo. 
in Malaya hav e hitherto be^n puSTished^. 
Dr. Purtado has carried pn necessary routine identification and 
checking of the names of living trees, shrubs etc. in the Gardens, in 
connection with the survey of plants and preparation of maps of the 
various areas of the Gardens. 'I

Ferns . The whole of ^he collections of Thelypteris and allied 
genera, comprising several hundred specimens, of 47 species , native in 
the Malay Peninsula, were studied , in comparison with recent work on 
Indian, Chinese and Javanese ferns, and descriptions and keys prepared 
for the Mala ya n species. Thj.s work occupied Mr, holt turn’s spare time _i 
th e month s of March^ j^ril and May, chi^iy_ in_the .,af^ 
side work had b°een dealt witi^^ A few illustrations were prepared. Some 
morF* ri lustra tio'n 3 , an3 a con^arative study of microscopic structures 
not yet examined, will be necessary before the work is ready for publi- 
cation. Many of t^hese ferns are common and widely distributed in tropic 
Asia, and no good account of them at 'pFesFnt^FxrFts.^^ “
