230 DR. O. STAPF ON THE FLORA OF MOUNT KINABALU. 
8—1 lin. longe ; pedicelli 3-4 lin. longi. Perianthium ad medium 5-lobum; lobi 2 
exteriores ovati, acuti, interiores cucullati, dorso sub apice filiformiter cornuti, 
omnes extus rigide pilosi. 
At 5000 feet (Haviland, 1219). 
A very graceful plant, the foliage of which imitates the compound leaves of certain 
forms of Thalictrum minus, particularly in the shape of the leaflets. It is allied to Æ. podo- 
phyllum, Wedd., but distinct by the cuneate base of the leaves and the absence of 
conspicuous cystoliths.

Cyme biflorz, sessiles, axillares; bracteze exteriores anguste oblong:e, vix 1 lin.

At 10,000 feet (Haviland, 1392). 
A very marked species, the affinity of which is difficult to ascertain. Perhaps it lies 
with Æ. glaucescens, Wedd. I do not know any other species where the cystoliths are 
so crowded on the upper surface of the leaves, which they cover entirely, with the sole 
exception of the black dots. The stiff short bristles of the lower surface are thickened 
at the base, and, in a young state at least, shining and yellow, so as to make it glitter 
from minute golden-yellow dots. 
ELATOSTEMMA LITHONEURUM, Stapf, n. sp. (Pl XIX. c. 9-16.) Herba, ut videtur,
