DR. O. STAPF ON THE FLORA OF MOUNT KINABALU. 141 
PERROTETTIA ALPESTRIS, Lósener, in Engl. Natiirl. Pflanzenfam. iii. Th. 5. Abth. 220. 
, Var. PHILIPPINENSIS, Stapf.—Syn. P. philippinensis, Lósener, 1. c.; Caryospermum 
philippinense, Vidal, Rev. Pl. Filip., 89. Flores tetrameri. 
A small tree on the Dahombang River, alt. 3000 feet (Haviland, 1389). 
Distribution (of species) : Malaya, from Sumatra to the Philippines. 
I find the flowers in Vidal’s type specimen of Caryospermum philippinense tetramerous, 
as they are in the Kinabalu plant; while all flowers which I examined from Sumatra and 
Javan specimens of P. alpestris, Lósener, were pentamerous. But apart from this I am 
not able to indicate any differential characters which might be used for separating these 
two supposed species. Lésener puts P. philippinensis and P. alpestris into his section 
Caryospermum, but neither of these specimens has solitary ovules. I dissected a great 
mauy flowers and fruits and found the ovary always 2-celled, with 2 erect ovules. In 
some cases, however, a slight ridge may be seen protruding between the seeds like a false 
septum, when they fill up the cells. Yet I rather derived the impression that this was 
the mere mechanical consequence of the pressure of the growing seeds against the soft 
ovary-walls. The flowers are polygamous, and show all intermediate states from male 
to female flowers. In the latter the stamens are replaced by almost petaloid, though 
small, staminodes without any trace of anthers, P. alpestris approaches very closely 
P. sandwicensis, A. Gray. 
SALACIA LAURIFOLIA, Stapf, n. sp. Frutex glaberrimus. Rami novelli subtetragoni, 
nigricantes, annotini albidi, teretes. Folia petiolo 2 lin. longo vel breviore suffulta, 
lanceolata, 23-83 poll. longa, 8-10 lin. lata, basi sensim attenuata, apice breviter 
acuminata, margine integerrimo leviter undulato, crasse coriacea, fusco-olivacea, 
nervis lateralibus utrinque 6-7, arcuatis, utrinque prominulis, reticulatione laxá, 
indistinctá. Inflorescentiz axillares vel extra-axillares, fasciculat:e, 6-10-flore ; 
pedunculi brevissimi; pedicelli 1 lin. longi. Calyx breviter cupularis, crasse et 
breviter 5-dentatus. Petala in alabastro anguste imbricata, oblonga, 1 lin. longa, 
crassa, in dorso carinata et glauca, suberecta, Stamina 3, ovario medio vel supra 
insidentia; filamenta late triangularia, apice demum recurva; anthere subquadrat:e, 
ł lin. longæ. Styli 3 breves. Ovarium 3-loculare. 
Young jungle on the Ulu Tawaran, alt. 2000 feet ( Haviland, 1370). 
Probably nearest to S. prinoides, DC., but very distinct by the thick, entire, lanceo- 
late leaves, and the carinate thick petals, which overlap each other only very slightly in 
bud.

Cissus HASTATA, Miq. Fl. Ind. Bat., Suppl. 512.—Syn. Vitis sagittifolia, M. Lawson, 
in Hook. fil. Fl. Brit. Ind. i. 645. 
At Koung, alt. 2000 feet (Haviland, 1372). 
Distribution: Malaya, from Penang and Sumatra to Borneo. 
Planchon, in DC. Monogr. v. (pars 2) 502, quotes “Vitis hastata, Miquel, Fl. Ind. 
Bat. Supplem. 517,” whereas Miquel in the passage cited calls the plant “Cissus hastata.” 
It must be therefore C. hastata, Miq., instead of Planch.
