350 MR. HENRY RIDLEY ON ORCHIDEZ AND 
Hab. Singapore: Kranji, &c.!| Common on trees in man- 
grove swamps. 
Selangor: Pataling, near Kwala Lumpur ! 
Perak : Scortechint. 
Also occurs in Java. 
This little plant is common on mangroves, and occurs also in 
damp forests, on branches of trees. It has a strong scent of 
Friar’s Balsam. 
The leaves described as trigonous are only so when the plant 
is dried. During life they are very thick and deeply channelled 
above, but not really trigonous. The lip is quite entire; I see 
no trace of the short lateral lobes of the other species. At the 
base is a low oblong mass of papille. The anther is helmet- 
shaped, with adistinct blunt beak. The pollinia are not sessile 
on the pedicel, but each pair is borne on a short, distinct stalk, 
which is affixed to the pedicel a short way from the end. The 
stigma is very large and occupies nearly the whole of the face 
of the very short column. 
AvENONCcOS MAJOR, Ridl., sp. nova. Caules 6-10 poll. longi, 
subflexuosi. Folia 2-3 poll. longa, 2 poll. lata, lorata, obtusa, 
carnoso-coriacea, apice inequaliter biloba; vagine ¢ poll. 
longer, rugose. Flores sessiles, axillares, singuli, virides. 
Bractew 3, ovate, coriaces, ovaria tegentes. Sepala + poll. 
longa, ovato-lancedlata acuta. Petala sepalis multo minora, 
linearia, acute. Labellum cuneatum, obovatum, carnosum ; lobi 
laterales minuti, medius apicerotundatus obtusissimus excavatus, 
carine basi papillosus, sub apice parvi-mucronatus. Capsula 
¢ poll. longa, oblonga ; costz fertiles late, sterilibus latiores. 
Hab. Johore: Batu Pahat! 
Pahang: Kota Glanggi, on limestone rocks ! 
Kedah: Kedah Peak ! 
This much resembles A. vireus, Blume; but the whole plant 
is very much larger, the leaves broader, longer, and of a different 
shape. The lip is rounded at the apex, and has distinct though 
minute lateral lobes. The petals, too, are much narrower. 
The sepals and bracts are full of bundles of white raphides. 
A. parvirtora, Ridl., sp. nova. Caules 2-4 poll. longi, 
suberecti, per totam longitudinem foliati; radices tenues. 
Folia 1 poll. longa, linearia acuta, crassa carnosa, in dorso 
convexa, superne canaliculata, recurva; vagine rugos. lores
