but the thick leaves with prominent midribs, thin pedicels, glabrous ovaries, 
short styles and dilated stigmas are unmistakable characters. The Kinitaki 
river, Haviland’s locality for this type, arises on one side of the Maraiparai 
spur. Stapf (17. 159) describes the flowers as white, suffused with red, 
but in the present instance they were true red in colour.

The leaves of this plant closely resemble those of R. acuminatum, Hook. f. 
in colour (when dry), texture and venation, but, including the petioles, are 
entirely glabrous on both surfaces, with a very thick and pronounced midrib, 
giving off 3-5 lateral nerves. The largest leaf is 9:5 cm. long and 4:7 em. 
broad, showing the veins very much impressed on the upper surface and 
prominent on the lower, which gives a markedly bullate appearance to the 
leaf. The raceme is many-flowered (with 13 flowers in my specimen), with 
yellow flowers on erect pedicels 3 em. long: the corollas are covered 
with entire seales on the outside, and show hairs on the inside at the base 
of the tube, which is 1 em. long and 5 em. broad, the lobes being 1:3 em. by 
lem. The anthers are partially exserted at the mouth of the tube, 33 mm. 
long, with filaments 1:3 em. long. The ovary is 0*4 mm. in length and 0:2 mm. 
in breadth. 
This plant is nearest to KR. acuminatum, Hook. f., in the shape and texture 
of the leaves, and in their verticillate arrangement, also in the entire scales 
investing the outer surface of the corolla, but approaches A. rugosum, Low, 
in the length of the pedicel, the size of the flower and in the hairy ovary ; in 
the yellow colour of the flowers it differs from either of the above species. 
This fine rhododendron has been named after Mr. D. R. Maxwell, Assistant 
District Officer for North Keppel, who accompanied me on the occasion 
of the ascent of Kinabalu. His disinterested kindness in taking the entire 
responsibility for the organisation and control of the expedition, left me free 
to devote my whole time to botanical work.
