DR. O. STAPF ON THE FLORA OF MOUNT KINABALU. 229 
angustee, ciliatze, vix breviores. Perianthium 4-5-partitum, 1 lin. longum; segmenta 
late obovata, paulo cucullata et sub apice cornuta, dorso pilosa. Ovarii rudimentum 
minutum. 
Kinitaki River, alt. 5000 feet (Haviland, 1271). 
Allied to £. rupestre, Wedd., but differing by the evidently flattened and strigillose 
stem, the narrow leaves, which have almost parallel margins, a very coarse serrature, 
and a usually very indistinct nervation. 
ELATOSTEMMA Lowi, Stapf, n.sp.— 2. Herba erecta, inflorescentiis exceptis glaberrima. 
Caulis inferne crassiusculus, nigricans, superne (exsiccatus quidem) sulcatus, ramis 
gracilibus. Folia alterna, sessilia vel petiolo brevissimo tenui suffulta, oblique 
oblongo-lanceolata, 13-2 poll. longa, 5-7 lin. lata, basi i» latere esteriore subauri- 
culatim producta, in latere interiore plerumque sensim attenuata, apice breviter 
vel caudato-acuminata, a medio vel fere a basi grosse crenato-dentata, tenuiter 
membranacea, supra nigricantia, subtus fuscescentia, siepe ob stomata prominula 
minute albo-punctulata, cystolithis utrinque (specie quidem) mullis, triplinervia, 
nervis lateralibus patulis utrinque 5-7, tenuibus. Stipule subulate, 3-1 lin. longe. 
Cym:e axillares, foliis sepe admodum diminutis sustente, sessiles, in receptaculum 
confluentes, 1-13 lin. dimetientes ; bracteze omnes anguste lineares vel spathulato- 
lineares, molliter pilosee, 1-4 lin. longze; pedicelli vix $ lin. longi. Perianthium 
tripartitum ; segmenta filiformi-linearia, pilosula. Staminodia paulo longiora vel 
breviora. Achenium ovatum, 3 lin. longum, pericarpio tenui, leviter tuberculato. 
At 5000 feet, on the northern face of Mount Kinabalu (Low). 
I have not been able to identify this plant with any of the species represented in the 
Kew Herbarium; only two, viz. E. Urvilleanum, Brongn., and E. lancifolium, Wedd., 
seem to come very near it. The former is figured in Brongniart, Bot. Voy. Coq. t. 46, 
fig. A, and is evidently very like in habit. But the leaves are more cuneate at the 
base in %. Urvilleanum, less acuminate, and full of cystoliths. The figure of the 
female flower as given by Brongniart is possibly wrong, as it shows only two perianth- 
segments and no staminodes. Æ. lancifolium, on the other hand, has a strigose stem 
and entire or sub-entire leaves, which are hairy below. 
ELATOSTEMMA THALICTROIDES, Stapf, n. sp.— g. (PL XIX. B. 5-8.) Caulis gracilis, 
firmus, teres, adpresse hirtellus; ramuli gracillimi, distiche foliati. Folia alterna, 
brevissime petiolata vel sessilia, suboblique cuneato-ovata, 6-9 lin. longa, 4 lin. lata, 
supra medium in uno latere extus spectante dentibus 2 majusculis, in altero ple- 
rumque dente unico magno vel alio parvo addito, dentibus mucronulatis, membra- 
nacea, supra leete viridia, pilis perpaucis adpressis conspersa, czeterum glaberrima, 
subtus pallidiora, in nervis et in margine adpresse tenuiterque strigillosa, nervis 
lateralibus tenuibus numero dentium. Stipule lanceolate, strigillosee, vix 4 lin. 
longe. Cyme axillares, pauciflore, in glomerulos 1-1$ lin. dimetientes congestz, 
dense pilosze; bracteze extime rotundato-ovate vel obovatze, sub apice breviter mu- 
eronulatz, dorso dense et rigide pilose; interiores spathulate, basi valde attenuatz,
