Species novae Acoridii generis in Philippinis insulis indigenae. 19 
pedunculo breviora; sepala lateralia late ovata, obtusa, 3-nervia; sepalum 
dorsale oblongum, obtusum, 3-nervium; labellum sagittatum, 3-lobatum, 
3-callosum, lobis lateralibus obtusis. 
A diminutive epiphyte with roundish or pyriform, rugose pseudobulbs 
5 mm long. 3,5 mm thick. Leaves shortly petiolate, 1,7—2 cm long, 
3—5 mm wide, sub-acute or obtuse. Peduncles longer than the leaves, 
flexuose, filiform, few flowered. Bracts about 2 mm long, exceeding the 
ovaries. Flowers small, brownish-red, orange when dry. Lateral sepals 
broadly ovate or orbicular-ovate, obtuse, 3-nerved, 2 mm long, by about 
2 mm wide. Upper sepal oblong, broadest above the middle, obtuse, 
3-nerved, 3 mm long. Petals broadly cuneate-obovate, broadest above the 
middle, 3-nerved, obtuse or sub-acute, 2 mm long, slightly more than 
2 mm wide. Lip contracted-sagittate, 3-lobed, with the middle-lobe bluntly 
apiculate or obscurely 3-lobed and the lateral lobes blunt and rounded 
with a large truncate tubercle at the base of each near the outer margin, 
and on the median line or disc of the lip a minute, very obscure papilla. 
Column short, with a very prominent protuberance in front,

1905, Elmer D. Merrill (no. 4481). 
In the Herbarium of the Bureau of Science at Manila this species 
and A. ocellatum are mounted on the same sheet. Both species were 
collected by Mr. Merrill at the same time. Only four plants were found, 
two of each species. 4. oliganthum belongs to that group of Euacoridium 
species which have the lateral lobes of the lip much smaller than the 
middle lobe and which merge with A. Whitfordíi and A. ocellatum.,

Pseudobulbi pyriformes; folia oblonga, obtusa; sepala lateralia ovata, 
obtusa; sepalum dorsale elliptico-oblongum, obtusum; petala ovata; se- 
pala petalaque ocellata; labellum incrassatum, 3-callosum, pentagulare, 
acutum. 
A diminutive, coriaceous-leaved species with ocellate sepals and 
petals. Pseudobulbs 1 cm long, about 5 mm thick, ovate-oblong or pyri- 
form, strongly rugose. Leaves shortly petiolate, oblong, 3,5—4,5 cm long, 
5—6 mm wide, obtuse. Petioles 5 mm long. Peduncle about as long as 
the leaves, few flowered. Bracts 3 mm long, erose-margined, longer than 
the ovaries. Lateral sepals ovate, obtuse, 2 mm long, 1 mm wide. Upper 
sepal elliptie-oblong, obtuse, 2 mm long, 3-nerved, the nerves branched. 
Petals ovate, about 2 mm long, 1 mm wide, like the sepals provided with 
diaphanous areolae or ocelli scattered among the semi-opaque tissues. 
Lip fleshy, about 1 mm long, 1,5 mm wide, pentangular, acute, the apical 
angle forming a triangular tooth; near the center on the median line a 
minute papilla is situated between two truncate tubercles. Column short 
and stout.

brownish-red flowers, October 29, 1905, Elmer D. Merrill (no. 4481 a). 
Acoridium ocellatum is readily distinguished from all other Philippine
