DR. O. STAPF ON THE FLORA OF MOUNT KINABALU. 227 
LAPORTEA STIMULANS, Miquel, in Zollinger, Cat. 103. 
At 5000 feet, 3-4 feet high (Haviland, 1222, 1230). 
Distribution: Malaya, from the Peninsula to the Philippines. 
Dr. Haviland’s specimens differ from the type specimens in their leaves being thinner 
and acute at the base or almost decurrent, but specimens from the Malayan Peninsula, 
chiefly from Perak, vary so much in these points that I doubt whether these characters 
can be relied upon. No. 1222 agrees exactly with a plant collected by Motley near 
Banjermassin (no. 346). Weddell says, in a note on the sheet, “forsan ad Z. crenulatam, 
var. B. referenda.” But I am inclined to refer this var. B., i. e. luzonensis, to L. stimu- 
lans rather than to Z. crenata, Gaudich. However that may be, L. crenulata and 
L. stimulans are extremely close. 
Laporte, sp. aff. L stimulanti, Miq. g. 
Penokok River, alt. 3000 feet ( Haviland, 1341). 
This is probably a new species, very distinct by the sessile or subsessile leaves, which 
are obovate-lanceolate and long cuneate at the base. The material, however, is too 
incomplete for description. 
PILEA JOHNIANA, Stapf, n. sp. (Pl. XIX. p. 17-26.) Herba perennis, nana, cæspitosa, 
e basi ramosa; rami prostrati radicantes, tenues. Folia densa, superne sepe densis- 
sima et internodiis multo longiora, petiolo $ lin. longo vel brevissimo latiusculo 
suffulta, orbicularia vel deltoideo-orbicularia, 1-13 lin. longa, basi brevissime 
latissimeque cuneata, apice obtusissima, carnosa, exsiccando nigricantia, triplinervia, 
nervis inconspicuis utrinque, sed precipue subtus, cystolithis linearibus minutis 
conspersa. Stipule minute, lanceolate, } lin. longe. Flores masculi in axillis 
solitarii, subsessiles. Perianthium bipartitum vel 4-partitum ; segmenta rotundata, 
cucullata, apiculata; stamina 2 vel 4. Flores feminei in cymulis axillaribus folio 
multo brevioribus, pewcifloris; pedicelli 3 lin. longi vel breviores. Perianthium 
tripartitum; segmentum intermedium vix ad 4 lin. longum, ovatum, cucullatum, 
quam lateralia, plerumque in margine glandulosa, 2-3plo longius. Staminum rudi- 
menta minutissima. Ovarium ovatum; stigma breviter penicillatum, sessile. 
Achenium suboblique globoso-ovatum, 1-3 lin. longum, leve. 
In crevices of rocks from 11,000 to 12,000 feet (Haviland, 1391). 
A very marked species, allied to P. peploides, Hook. et Arn. It differs by the very 
erowded, almost sessile leaves, which are thick and not transparent in a dry state, the 
few-flowered inflorescence, and the larger achenes. I saw but one male flower, from 
which the description is drawn.
