PLANT COLLECTION 
In March the Director undertook a short expedition to Gunong Muntahak 
and the upper tributaries of the Pelepah River in S. E. Johore. 
Though few trees were flowering, a number of interesting plants were 
collected for the herbarium and the garden. The most notable was a new' 
species of Pomazota (Rubiaceae), a genus hitherto only known as a single 
species frcm Pahang. 
Mr. M. R. Henderson visited the Anamba Islands in April, accompanied 
during the first part of the expedition by Dr. C. G. G. J. van Steenis 
of the Herbarium of the Botanic Gardens, Buitenzorg. The island of Siantan 
was first visited, and thanks are due to the Dutch Controleur and his wife, 
Mr. and Mrs. L Wrede, for much kind help and hospitality. The latter half 
of the time was ( spent by Mr. Henderson on the island of Jemaja, while Dr. 
van Steenis visited the Natuna Islands. The results w r ere rather disappoint¬ 
ing, owing partly to the low elevation of the islands, and partly to the scarcity 
of plants in flower. Several interesting orchids were brought back alive to 
Singapore, among them very large plants of Dendrobium hercoglossum and 
Saccolabium Harrisonianum. An interesting plant association on an old 
sandy beach was studied. 
During April Mr. Mohamed Haniff (formerly Field Assistant at Penang) 
was employed to collect herbarium material for the Gardens. He visited the 
foot of Gunong Bintang on the Kedah-Perak boundary, and brought back a 
small but valuable collection, which indicates that this region would repay 
further study. Unfortunately illness of coolies and bad weather prevented 
Mr. Haniff from actually climbing the mountain. He obtained, among other 
things, a fine Barringtonia which may prove to be new. 
Between August 19th and September 10th, the Director visited Gunong 
Tahan. Local arrangements had previously been made by Mr. C. E. Carr 
of Tembeling, who accompanied the expedition. The District Officer of 
Kuala Lipis kindly lent the services of the Penghulu of Kuala Tembeling, 
whose local knowledge and keenness were invaluable. Collections were made 
by the Tahan and Teku rivers, in the valley below Wray’s Camp (about 3,000 
feet altitude), and on the ridge beyond, to the “padang” and summit. 
Mr. Carr’s special knowledge of orchids resulted in the collection of a very 
fine series of specimens, including several additions to the flora of the Penin¬ 
sula and some new species. Of other plants, many of the local species of 
Tahan, hitherto only known from Mr. Ridley’s collections, are now available 
for distribution to other herbaria. A peculiar new Elaeocarpus was obtained. 
A very interesting collection of ferns and mosses resulted in the addition of 
several species, in both groups, to Hie flora of the Peninsula. 
HERBARIUM WORK AND OTHER INVESTIGATIONS. 
Mr. Henderson continued herbarium routine work as usual, and all 
arrears of unnamed specimens have now been either named or sent away for 
determination. Assistance from the Director of the Royal Gardens, Kew, 
in the identification of specimens, is gratefully acknowledged. A consider¬ 
able number of specimens have been lent for study, chiefly to the Buitenzorg 
herbarium. The study of our material in this way by specialists who are
