forest on the sandbanks which develop across the river mouths. Many 
interesting or little-known species were discovered, including Inocarpus edulis 
(the so-called Otaheite Chestnut, not previously known as indigenous to the 
Peninsula), a species of Phaleria (a genus not hitherto found in the Peninsula), 
Cliisocheton pentandrus (a Philippine species), and several other species which 
will need further study. Mr. Corner unfortunately contracted Japanese River 
fever on this expedition; he managed to return to Singapore in time for 
treatment, and recovered after a very serious illness. Mr. Corner also made 
several short trips to the vicinity of Mawai, Johore, and grateful thanks are 
expressed to Mr. H. G. Grieve of Tebrau Estate for his assistance and 
’ hospitality on these occasions. 
In June the plant collector Kiah accompanied Mr. C. F. Symington of the 
Forest Department on a short trip to Gunong Tapis, near Kuantan, Pahang. 
No previous botanical collections are known to have been made on this mountain, 
and the present one, although small, is of considerable interest. 
In November Mr. Henderson visited Pulau Langkawi for the express 
purpose of collecting on the limestone there. Collections were made on the 
limestone ridges on the east of the island, on Pulau Timun, and on the north 
and south coasts of Pulau Dayang Bunting, and a day was spent at Kisap, 
near Kuah, where there is a small limestone hill. Unfortunately very few trees 
were in flower at this time and from this point of view the expedition was 
disappointing. However, a very good general idea of the composition of the 
limestone flora here was obtained, and of plants other than trees, many of 
interest were found. Perhaps the most interesting was a species of Lysimachia 
which constitutes the first record of the family Primulaceae from our area.
