DR. O. STAPF ON THE FLORA OF MOUNT KINABALU. 159 
sessiles, terminales vel axillares ; pedunculus crassiusculus, brevissimus, bibracteatus. 
Bractew ovate, 2-3 lin. longe. Pedicelli graciles, 8-9 lin. longi, glaberrimi, demum 
incrassati. Calyx breviter campanulatus, 11 lin. longus, glaber, minute verru- 
culosus ; limbus deciduus, 4-lobus; lobi ovato-lanceolati, Jaleato-recurvi, vix 1 lin. 
longi, apicem versus setulis paucis ciliati. Petala rosea, oblonga vel obovata, 
5 lin. longa. Stamina $, sequalia ; filamenta 13 lin. longa; anther aureze, lineari- 
laneeolate, 13 lin. longee, obtusiuscule, basi vix bilobe, antice appendiculatee, 
postice breviter calcarate. Ovarium ut in P. wniflord. | Capsula subhemispherica, 
subtetragona, costulis prominulis 8; valve 4, emarginate. 
In damp places, from 4000 to 5000 feet (Low; Haviland, 1286). 
A very well-marked species, nearer allied to P. tonkinensis, Stapf, than to the Bornean 
species hitherto known, but differing remarkably in the shape and the indumentum of 
the leaves, the almost sessile few-flowered cymes, the smaller anthers, and the distinctly 
emarginate valves. The extremely short peduncle and the reduction of the involucre 
to two small bracts give the plant a very different appearance when compared with 
P. tonkinensis, but the floral structure is the same, apart from the smaller size and the 
more linear shape of the anthers; and the ripe capsule is almost exactly of the same 
kind in both species. The general appearance, however, of P. uniflora is so very different 
from that of any Phyllagathis we know that I should not have hesitated to make it the 
type of a new genus if the structure of the flower and the capsule were not exactly the 
same as in P. elliptica; besides, the indumentum and the texture of the leaf point likewise 
to Phyllagathis. The inflorescence, too, though totally different at the first glance from 
that of P. rotundifolia, can easily be understood when compared with that of P. elliptica. 
The reduction of the peduncle and of the bracts is carried on still a little further and 
the cyme reduced to a single flower. It is true the habit is very different; but if we 
remember the great variety which the genus Sonerila exhibits in its vegetative archi- 
tecture, while yet so uniform in its plan, we cannot separate the plant in question from 
Phyllagathis only on account of the habit. 
MARUMIA PACHYGYNA, Korth. Verh. Nat. Gesch. Bot. 242, t. 59. 
On the edge of a clearing, Penokok, alt. 3000 feet (Haviland, 1345). 
Distribution : Borneo. 
The leaves of the Kinabalu specimen agree exactly with those of M. stellulata, Blume, 
which comes extremely near and only differs in the ciliate calyx and the smaller flowers. 
Dr. Haviland says in a note, “ petals white." Korthals figures them pink. The 
colour evidently varies from pink to white. 
DISSOCHETA ANNULATA, Hook. fil., ex Triana, in Trans. Linn. Soc. xxviii. 83. 
At Bongol, on the Tawaran River, alt. 1200 feet (Haviland, 1385). 
Distribution: West Malaya, from Penang to Borneo; Ceram. 
DissocHaTA HIRSUTA, Hook. fil., ex Triana, in Trans. Linn. Soc. xxviii. 83. 
Climbing in trees in young jungle on the Ulu Tawaran, alt. 2000 feet, and near Kiau, 
alt. 3500 feet (Haviland, 1287, 1288).
