196 DR. O. STAPF ON THE FLORA OF MOUNT KINABALU 
Allied to Rhododendron Lowi, but the flowers reddish white and much smaller. 
There are 4 flowers with the specimen, 3 of them detached. It appears to me, from the 
scars on the axis of the inflorescence, that there were not more on it. 
RHODODENDRON BROOKEANUM, Low, ex Lindl. in Journ. Hort. Soc. iii. (1848) p. 42. 
A lanky shrub, growing on a tree-fern, but taller than it,” at 7800 feet (Haviland, 
1149). 
Distribution : North Borneo.

ceolata vel linearia, 1$-2$ poll. longa, 1-2 lin. lata, basi iu petiolum brevis- 
simum attenuata, acuta vel interdum fere setaceo-acutata, coriacea, sparsissime

anthere oblong, 2 lin. long. Ovarium cylindricum, 2} lin. longum, dense 
albo-tomentellum, 5-loculare ; stylus 3 lin. longus; stigma dilatatum. 
In very shady, mossy places, from 5000 to 8000 feet (Low, Burbidge ; Haviland, 1104). 
Closely allied to R. salicifolium, Becc., but differing in the very narrow leaves and 
smaller corollas with a wider tube. The specimens collected by the three gentlemen 
mentioned are very uniform. The sequence of the leaves is very remarkable, though 
typically the same as in the other species of $ Eu-Rhododendron. Sir Hugh Low's 
specimens as well as Haviland’s were collected in the spring, At this time all branches 
terminate with a cluster of persistent leaves which correspond to the “ Sommerblátter ” 
of R. ponticum (Maximowicz), and surround a very young bud. ‘To judge from the 
dried material, these buds grow out during the following season into young branches of 
1-2 in. in length, shifting the inner bud-scales along with them, till at a certain time the 
normal leaves appear in great numbers, terminating the growth of that season. What 
the length of that period is I do not know, but it seems very probable that more 
than one shoot is formed every year. The branches may grow for several consecutive 
periods without lateral ramifications, but when these are formed they always spring from 
the axils of * summer leaves," and in a very limited number (2-1). The membranaceous 
or scarious leaves pass into the summer leaves sometimes through one or two inter- 
mediate leaves, but more often they follow each other abruptly. Different as R. steno- 
phyllum may seem if compared with R. javanicum, they yet belong to the same group.
