130 DR. O. STAPF ON THE FLORA OF MOUNT KINABALU. 
G. stenopetalus is a very well-marked species, distinguished by the long and narrow 
outer petals. It approaches most nearly G. macrophyllus, Hook. fil. & Th., a species 
indigenous in Sumatra and Malacca. 
GONIOTHALAMUS ROSEUS, Stapf, n. sp. Cortex ut in G. stenopetalo. Folia quoque consi- 
 millima, imprimis quoad nervationem, sed majora, pro ratione angustiora (113 poll. 
longa, 2} poll. lata), ez:eterum valde variabilia, in ramulis novellis interdum vix 4 poll. 
longa. Pedunculus 13-13 poll. longus, robustior. Sepala basi connata, late triangu- 
laria, 3-4 lin. longa, acuta, glabrata. Petala exteriora rosea, e basi late unguiculatá 
ovato-lanceolata, apicem versus longe attenuata, ad 23 poll. longa, 6-7 lin. lata, por- 
recta, uninervia, fere glabra, crassiuscula; interiora ebasi indistincte unguiculatá ovata, 
ad 10 lin. longa, ad 4-5 lin. lata, acuta, in marginibus parce albido-puberula, ceeterum 
fere glabra, crassa. Stamina numerosa, linearia ; connectivum depresso-capitatum, 
minutissime papillosum; antherarum loculi distantes. Ovaria numerosa, ovato- 
oblonga, aureo-hirsuta, in stylum 2-3-plo longiorem, angulo fere recto curvatum 
abeuntia ; stigma truncatum, unilateraliter fissum ; ovulum basilare, solitarium. 
At 6000 feet (Haviland, 1312). 
This plant is so very similar to G. stenopetalus in the vegetative parts that I should not 
hesitate to refer it to that species but for the remarkably different flowers. These are twice 
or three times as large, and have so different a shape that I cannot think this could be due 
to a more advanced state; besides, they are much thicker and more fleshy. 
MirrepHora MAINGAYI, Hook. fil. & Thoms. in Hook. fil. Fl. Brit. Ind. i. 77; King, 
Mat. Fl. Malay Pen. no. iv. 86. 
At 3000 feet, Dahombang River (Haviland, 1311). - 
Distribution : From Malacca to South Burma, Java, and Borneo. 
I refer this plant with some reluctance to M. Maingayi. The leaves are more 
membranaceous and more glabrous than in any specimen I have seen of M. Maingayi. 
On the other hand, the floral structure is the same, and the same venation of the 
leaves may be found also in some of the specimens of JM. Maingayi of the Malay 
Peninsula. Scheffer described a plant under the name of M. glabra (Ann. Jard. Bot. 
Buit. ii. 20) from Selaboun in Borneo, which evidently is very similar to that from Kina- 
balu; but there is nothing in the description that would not apply also to M. Maingayi, 
at least in the broad sense in which it is understood by Dr. King. |
