382 MR. HENRY RIDLEY ON ORCHIDEX AND 
inequaliter biloba; rostellum planum, integrum, tenuissimum, 
album. Stigma profundum. Capsula 5 poll. longa, cylindrica, 
gracilis. 
Hab. Singapore: very common on orchard trees, in gardens 
and elsewhere often doing considerable injury by 
overloading the boughs and eventually killing them. 
Pahang: Pekan ! 
Perak: Kwala Kangsa! 
The figure in the ‘ Icones Plantarum,’ t. 2123, was partly based 
on a drawing I sent to Kew, which was taken from a flower 
partly withered, and fertilized. The flowers are so fugacious, 
that unless they are carefully watched they cannot be got in 
good condition. The sepals are very unequal ; the lateral ones 
having the lower margin at the base prolonged downwards, as 
if to form a mentum. The lip has the ordinary form of a 
Dendrocolla, the lateral lobes being turned up, and they as well 
as the disc behind the callus are covered with white hairs. The 
column as figured in the ‘ Icones’ represents that of a fertilized 
flower, the sides and the upper edge of the clinandrium having 
folded in over the stigma. 
DeENDROCOLLA PARDALIS, Ridl. Sarcochilus pardalis, Ridl. in 
Trans. Linn. Soc., Ser. II. (Bot.) iii. (1893) p. 371. 
Hab. Pahang: thickets along the River Pahang! 
TD. carinativona, Ridl. Sarcochilus carinatifolius, Ridl. in 
Journ. As. Soc., Straits branch (June, 1891) p. 136. 
Hab. Pulau Aor, J. Feilding ! 
This little plant, which I obtained in Christmas Island, south 
of Java, was found in abundance in Pulau Aor, an island lying 
east of Johore, by Mr. Feilding. It has not yet appeared on 
the mainland. The lip with its long falcate lateral lobes 
and well-developed epichil somewhat resembles that of a 
Thrixspermum. 
Sarcochilus recurvus, Hook. f., Fl. Brit. Ind., vi. p. 39, et 
Ic. Pl., t. 2122, is, I fear, unrecognisable with certainty. It was 
described from flowerless specimens. It might be D. pardalis, 
or one of the others of this group; but there are a number of 
which my materials are insufficient, which would pretty well 
suit the figure. 
D. Fitirormis, Ridl. Sarcochilus filiformis, Hook. f., Fl. 
Brit. Ind., vi. p. 39, et Ic. Pl. t. 2124. Caulis 2-4 poll.
