the occurrence of the other similar blocks, the soft pudding-stone having 
worn away and so caused the breaking up of the material it bound together. 
At the base of Lobang rock grew Desmodium Scalpe and Adiantum hispidulum 
with /teboul/a hemispherica var. javanica. Fine trees of Goniothalamus roseus 
and Tarenna Gibbsiv sheltered in the immediate vicinity of the rock a dense 
upgrowth of young plants of the former species, flowering at 3 metres, with 
Psychotria malayana, a Cyrtandra, and Calanthe kinabaluensis as common 
undergrowth. 
In the bed of the stream and spreading up the banks, Sambucus javanica 
was in flower, also Polygonum chinense, Cyrtandra Burbidgei with stiff un- 
branched stems, about 1 metre high, and most peculiar large white bracts all 
up the stem, veiling the inconspicuous flowers, and the white-flowered Pratia 
borneensis, a herb of shrubby habit. 
Crossing the stream, one mounts on the other side up steep shingle slopes, 
with little undergrowth beyond sticky shrubs and a few plants of Adenostemma 
viscosum, Blumea balsamifera and Mikania scandens. The shingle slopes end 
sharply under a series of rock-ledges, to which they no doubt owe their 
origin. These ledges form the shoulder of the ridge of the south-western spur, 
which is followed in the ascent to the granite core. Still in high forest, they 
were partly veiled thickly by interlaced moss-covered roots of trees and, in 
the steepest parts, overhanging branches, while other areas were covered 
with the most luxuriant vegetation so far seen. 
The trees found here were the green-flowered Urophyllum nigricans, Blastus 
Cogniaueit with inconspicuous white flowers, and Ardisia amabilis, also white, 
then Sterculia translucens and Drimys piperita, as abundant here as on the 
Gurulau and Maraiparai spurs, and fine examples of Podocarpus imbricatus, 
P. brevifolius, and Phyllocladus hypsophylla. Among the undershrubs, the 
magnificent Rhododendron Lowi, with a rounded top, covered with huge 
bunches of splendid yellow flowers of a fleshy texture, grew out conspicu- 
ously from the. ridges, whilst R. Maawellit, also yellow-flowered, occurred in 
this association along with the slender overhanging Rubus fraxinifolius. The 
luxuriant undergrowth of these favoured slopes and ridges seems entirely 
herbaceous in character. The handsome Begonia Burbidgei, averaging 
2 metres in height, a mass of large pink flowers, was growing thickly with 
Strobilanthes kinabaluensis and S. Galeopsis, the latter contrasting with white 
flowers and reddish leaves, and Pratia borneensis and Hedyotis pulchella, a 
herb of similar stature, were equally abundant. Impatiens platyphylla, 
Elatostema thalictroides, Rhuacophila javanica and Ophiopogon malayanus, 
all of smaller growth, formed a substage, under which again Chlorophytum 
brachystachyum, | .Elatostema rubro-stipulutum and FE. penibukanensis, the 
pink Sonerila pulchella and Oplismenus compositus occurred associated with 
orchids. 
Nertera depressa and Peperomia decumbens covered old tree-stumps, and
