Kranji Reserve and in the Reservoir Jungle. After his return from leave, 
Mr. Corner resumed his visits to south-eastern Johore, and a week’s 
collecting was carried out in July near the Sedili River. Some interesting 
plants were found on the hill known as Tinjau Rant, east of the river. 
Mr. Henderson twice visited the neighbourhood of Pontian in south¬ 
western Johore; thanks are due to the Assistant Adviser, Pontian, 
(Mr. R. V. Brant) for liis assistance in making the necessary arrangements. 
One visit was to the island of Pulau Kemudi, in the Pulau Pisang group. 
The other visit was to peat forest, of which there is a considerable area 
remaining near Pontian. The flora was found to be similar to that of the 
forest formerly existing near the Jurong Road, Singapore, felled in 1932-33 
and studied by Mr. Corner. The peat forest of Pontian is also similar in 
many respects to the fresh-water swamp forest of S.E. Johore, but differs 
notably in the scarcity of the genus Eugenia. 
In June, Mr. Hoettum paid a short visit to Sepang, Selangor, by 
invitation of Mr. F. C. Fogh of Teluk Merbau Plantations, Ltd., and 
collected some interesting plants in the coastal country. The neighbouring 
mangrove contains considerable quantities of orchids of the genus Arachnis; 
these are Arachnis flos-aeris var. gracilis (a small variety described some 
years ago from cultivated plants in Singapore) and several varieties of 
the natural hybrid Arachnis Maingayi. Plants of these have been collected 
and cultivated by Mr. Fogh. Another interesting plant discovered by 
Mr. Fogh is Nepenthes trichocarpa, growing under conditions which 
indicate clearly that it must be a hybrid between the common pitcher plants 
N. gracilis and N. ampullaria; the existence of such a hybrid was not 
formerly suspected. A single plant of N. trichocarpa was subsequently 
found at the Gap in Singapore. In August, Mr. G. H. Addison paid a 
week’s visit to the forest in the neighbourhood of the Gap (F.M.S.) collecting 
herbarium specimens and also local plants (particularly Begonias) for culti¬ 
vation. Mr. Hoettum took leave at Fraser’s Hill over the Christmas 
holidays, and made some further observation on the local ferns, particularly 
of the difficult genus Diplazium. 
Mr. C. X. Furtado visited the Pontian district of Johore towards the 
end of the year, in connection with his study of Keladis (see below). He 
found 14 distinct varieties, some of them different from the Lower Perak 
collection made by Mr. E. F. Aleen. 
BOTANICAL RESERVES 
The three Botanical Reserves in Singapore mentioned in the Annual 
Report for 1938 were finally gazetted as Forest Reserves during the year. 
This designation is for purposes of administrative convenience; the 
Reserves are primarily for the preservation of typical areas of natural 
vegetation, and control is entirely in the hands of the Gardens Department. 
For the purpose, the Director of Gardens is gazetted as a Conservator of 
Forests. 
Regular patrols at Bukit Timah have reduced cutting of timber to very 
small proportions. Two arrests for timber cutting were made during the 
year. New growth in areas formerly devastated continued satisfactorily. 
Six arrests were made in the Kranji Reserve, where men were regularly 
employed in making a boundary path during a considerable part of the year. 
At Bukit Timah, collection of specimens, and naming and labelling of 
trees continued. The numbered trees were increased to 440, but not all 
these have yet been identified. Nearly two miles of new paths were made 
in the Reserve during the year. The greater part of this was a boundary
