acuminate apices, and four narrow lateral ones, rounded at the apex, all 
pilose on the outer surface, with membranous ciliate wings. No d flowers 
were found. The 9 cymes are about the same size or somewhat smaller, 
with an involuere of two larger opposite bracts, and many narrow ligulate 
ciliate ones. The 9 flower is pedicellate, and characterised by an unusually 
well-developed 4-partite perianth, with lobes 2-4 mm. long, which is 
succeeded by four inflexed staminodes. In the sterile flowers the perianth 
shows even greater development. ‘Ihe achene is brown, 2 mm. long. 
This species is nearest to Æ, Lowii, Stapf, collected at 5000' on Kinabalu 
by Low. It differs in the unbranched habit, in the very hairy stems, the 
petiolate and less oblique leaves with cuneate bases, and the veins which are 
on the under surface being densely clothed with hairs.

In this plant the creeping rhizome sends up single aerial shoots, or 2-3 
from one node, The shoots are dorsiventral, and recurved at the apex, 
15-78 dm. in height and leafy for about } to } up the stem, where they 
are 0*7 dm. broad. The stipules are lanceolate, membranous, yellow-green 
in colour, 6 mm. long and 2 mm. broad. The leaves are olive-green in the 
dried condition, the petiole being 2 mm. long, while the largest leaf is 3 em. 
long and 1:6 em. across. The £ cymes are shortly pedunculate, solitary 
and axillary, 7 mm. in length, with the involuere composed of 6 bracts, the 
two largest on the outside with the four smaller at right angles to them, all 
hairy on the outside; the g flowers are few in number, and characterised 
by the length of the pedicel, which is 6 mm. long, the perianth is 1-partite, 
3 mm. long and 2 mm. across, each lobe terminated by a tuft of cilia. The 
? cymes are sessile in the axils of the lower leaves, round in outline and 
6 mm. across, with involueres consisting of two larger bracts and a number 
of narrow ciliate smaller ones. The 9 flower is pedicellate and shows a 
gland-eiliate perianth of four minute segments, succeeded by ineurved 
sta uinodes ; theovary is 1 mm. long. A sterile flower showed three perianth- 
segments and three incurved staminodes. 
This plant is nearest to the Philippine Æ. obovatum, Wedd., from which it 
differs in the erect habit, and petiolate acuminate leaves, cuneate at the base. 
The g flowers are not known for Æ. obovatum, but in the present species 
they differ from most members of the genus in the very long pedicels.
