and D. secundum, Lindl., Eria bractescens, Lindl., Acriopsis, &c., while a fine white- 
flowered Renanthera scrambles over and through the bushes. 
On the right bank of the river at Pekan the country is more swampy and less sandy. 
Large tracts are covered with Saccharum Ridleyi, Hack., and. great tufts of “ Palas” 
(Licuala spinosa, Griff.), and there are many pools full of Nelwmbiwm Lotus, Linn., and 
in drier places Clerodendron Siphonanthus, Linn., and a small species of Crinum, perhaps 
C. defizwmn, Herb., are abundant. Тһе river-banks in many places are clad with dense 
thickets hanging down to the water's edge, interspersed with trees of Lagerstramia, the 
pink-flowered Cassia nodosa, and. golden C. siamea and Millettia atropurpurea, which, 
with great masses of orange and red Bauhinias and clumps of white-flowered Clinogyne, 
make this district very beautiful. 
The next distinct flora is that of the Kota Glanggi limestone rocks in the woods of 
Pulau Tawar. This region produces many plants not met with elsewhere in Pahang, 
but occurring also ina similar locality in Kwala Lumpur in Selangor ; such are: Procris 
LEpithema, Begonia, Elatostemma, and Saraca cauliflora, Baker, a tall slender tree with 
great trusses of orange-yellow flowers and large pink pods. Among the most important 
discoveries in this locality were Protamomum, a new genus of Musaces, Pomazota, 
а new genus of Rubiaces, the curious Trichopus zeylanicus, hitherto only known to 
occur in Ceylon and Southern India, a fine Didymocarpus (D. quinquevulnerus) with 
white flowers tipped with crimson, a remarkable Geophila, and many orchids. 
The woods at the mouth of the Tembeling River (Kwala Tembeling), where it unites 
with the Pahang River, produced an abundance of interesting plants, but none more 
so than Brugmansia Zippelii, the first Rafflesiad recorded from the Malay Peninsula, 
though I have since seen specimens of a species of Rafflesia collected by Mr..Wray in 
Perak. 
Passing up the Tembeling River we begin to meet with the first traces of the sub- 
alpine flora of the Tahan River, and on entering the valley of that stream we find 
ourselves in a totally distinct flora. The rocky banks of the river are clad with a dense 
forest of trees and shrubs, the most conspicuous of which is an undescribed species 
of Dipterocarpus, bright at the time of our visit with its pink fruit, or scenting 
the air with its large pinkish cream flowers. Its boughs were loaded with Celogynes, 
Dendrobiwms, and many other orchids, including Grammatophyllum speciosum in 
magnificent flower. à 
The hills which enclose the rocky stream are upwards of 2000 feet altitude, and 
composed of quartzite, clad to the top with tall trees. One could not but be struck 
by the similarity in form of the foliage of the chief plants which grew close to the 
water's edge. There was here quite a series of plants with peculiarly long, narrow, 
acuminate leaves, such as the specific name salicifolia suggests. They belonged to 
all manner of orders, and included a Calophyllum, an Irora (I. stenophylla, Miq.), 
a Hygrophila (H. saxatilis, n. sp.), an Antidesma (A. salicifolia, Miq.), a Didymo- 
carpus (D. salicina, n. sp.), a new genus of Asclepiadeze (Spiladocorys), а Podochilus 
(Р. Maingayi, Hook.), a Ficus (F. pyriformis, Hook.), a Rhynchopyle, and a Melastoma. 
The forms of leayes in the tropical woods bear a great relation to the amount and force
