ridge from Tenompok to the summit, and also in the Kadamaian valley a short 
distance below Kamborangah (7,000 ft.) ; the forest near the river at this 
altitude was very damp, and rich in interesting fern species. .On the return 
journey the descent was completed by the old route from Kamborangah to 
Lobang, and thence the forest in the neighbourhood of the Kadamaian at about 
3,000 to 4,000 feet altitude was explored, many interesting plants being found. 
After returning to Kiau, a brief visit was paid to the Marei Parei ridge, where 
several species not previously seen were taken. It is hoped that an account of 
the ferns collected will be published later. 
HERBARIUM WORK AND OTHER INVESTIGATIONS 
General herbarium of Flowering Plants . Mr. HENDERSON carried on the 
usual routine work, and by the end of the year all collections to date had been 
worked over, except for the families Ebenaceae, Styracaceae, and Symplocaceae, 
which are in the hands of the specialists at Buitenzorg. Mr. Henderson pre¬ 
pared a second list of additions to the flora of the Peninsula since the publication 
of Mr. Ridley's Flora, for publication in the Gardens Bulletin. Mr. Henderson 
also spent a good deal of time in preparation for three months study leave which 
he is to spend at Kew during 1932. Thanks are due to the staffs of the herbaria 
at Kew and Buitenzorg, to Mr. C. E. Carr and Dr. A. S. Hitchcock, for deter¬ 
mination of critical or doubtful plants; and to the Royal Botanic Gardens 
Calcutta for the loan of specimens. Specimens have been received on an 
exchange basis from the Botanic Gardens, Buitenzorg, Prof. W. G. Craib (Aber¬ 
deen), Dr. A. F. G. Kerr (Bangkok), the Imperial Forestry Institute (Oxford), 
the Bureau of Science, Manila, the Forestry Research Institute, F. M. S., and 
the Royal Gardens Kew. Specimens have been mounted and laid into the her¬ 
barium as follows: 
Malay Peninsula and cultivated plants .. .. 2,053 
Acquired by exchange from other institutions . . 3,682 
Total .. 5,735 
Herbarium of cultivated plants. Mr. Furtado continued work on this 
herbarium, paying particular attention to the gymnosperms and the families 
Orchidaceae and Zingiberaceae. He also named a considerable number of 
specimens of plants from the Gardens, duplicates of which have been distri¬ 
buted to other herbaria. A number of corrections to the names of palms in the 
Gardens have been made, chiefly owing to the assistance of Captain H. A. 
Johnstone, who spent about three weeks in Singapore and gave us the benefit 
of his intimate knowledge of palms growing in other tropical Botanic Gardens. 
Cordial thanks are due to Captain Johnstone for this assistance. 
Cryptogamic herbarium. The Director continued work on the ferns. A 
short paper was published concerning Aspidium Maingayi (Baker), a curious 
local species which has been much misunderstood. A considerable 
amount of work was spent on a revision of the genus Stenochlaena, and for 
this purpose specimens were borrowed from the herbaria at Buitenzorg, Manila, 
the University of California, and from Dr. E. B. Copeland; for the loan of these 
specimens^grateful thanks are offered. By the end of the year a paper embody¬ 
ing the results of this study, and incorporating a considerable amount of original 
field observation, was completed; this will be published in the Gardens Bulletin. 
As in former years, collections of mosses and liverworts have been sent to 
Mr. H. N. Dixon and to Mr. W. E. Nicholson for determination, and thanks 
for this service are again expressed. 
Mr. Corner devoted much of his time to the continuation of his fungus 
studies. He gave special attention to the systematy of the Polyporaceae and 
two further papers on the subject were written, one on the identity of the 
fungus causing the Wet-Root Rot of rubber trees, namely Ganoderma pseudo- 
ferreum, and the other on the structure of a new species of Fomes, called 
F. levigatus, grown in the Botanic Gardens. The identity of the fungus causing 
Brown Root of rubber trees has also been settled and the results will be pub¬ 
lished shortly under the new name of Fomes noxius. Several collections of 
fungi were received during the year from the Department of Agriculture, 
Kuala Lumpur, and the Rubber Research Institute, Kuala Lumpur, for identifi¬ 
cation.
