Ames — New Species of Aroridium from the Philippines. 151 



Acoridium ocellatum sp. nov. 



Pseudobulbi pyriformes; folia oblonga, obtusa ; sepala lateralia ovata, 

 obtusa; sepalum dorsale elliptico-oblongum, obtusum; petala ovata; sepala 

 petalaque ocellata; labellum incraspatiiin,3-callosain, pentagulare, acutum. 



A diminutive, coriaceous-leaved species with ocellate sepals and petals. 

 Pseudobulbs 1 cm. long, about 5 mm. thick, ovate-oblong or pyriform, 

 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 

 elliptic-oblong, obtuse, 2 mm. long, 3-nerved, the nerves branched. Petals 

 ovate, about 2 mm. long, 1 mm. wide, like the sepals provided with dia- 

 phanous 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. 



From Mt. Data, Distr. Lepanto, Luzon, alt. 7,000 ft., epiphyte with 

 brownish-red flowers, October 29, 1905, Elmer D. Merrill (No. 4481a). 



Acoridium ocellatum is readily distinguished from all other Philippine 

 species of the section Euacoridium by the scattered ocelli on the sepals and 

 petals. 



Acoridium Merrilli sp. nov. 



Pseudobulbi fusiformes ; folia oblongo-lanceolata, acuta; sepala lateralia 

 lineari-lanceolata, acuta; petala oblongo-lanceolata, quam sepalis breviora, 

 margine minute denticulata; labellum 3-lobatum, lobis lateralibus rotun- 

 datis, quam lobo medio emarginato minoribus. 



Near DendrochVum exalata J. J. Smith. Pseudobulbs clustered, mono- 

 phyllous, 2-2.5 cm. long, fusiform, grooved and furrowed when dry, sheaths 

 2.5-7 cm. long, maculate, acute. Leaf oblong-lanceolate, acuminate, acute, 

 11-14 cm. long, about 2 cm. wide. Petiole 2.5-3.5 cm. long. The prom- 

 inently nerved lamina of the leaf, which becomes very dark in color when 

 dried, passes abruptly into the petiole. Peduncle very slender, 0.5 mm. in 

 diameter, naked, without imbricating bracts at the summit below the in- 

 florescence, equalling the leaf or slightly shorter. Inflorescence a loose, 

 graceful, comparatively large-flowered raceme, 1 dm. long, 1.5-2 cm. 

 through. Floral bracts linear-lanceolate, acute, about 3 times longer than 

 the ovary and pedicel, 4-7 mm. long, the slender awn-like apical portion 

 up-curved. Flowers 4 mm. apart. Lateral sepals linear-lanceolate, acum- 

 inate, acute, carinate, 3-nerved, 9 mm. long, 2 mm. wide, spreading ; upper 

 sepal similar to the lateral ones, of equal length with them. Petals oblong- 

 lanceolate, microscopically and irregularly toothed along the margin, acute, 

 3-nerved, 6 mm. long. Labellum with 3 thickened nerves, ecallose, 5 mm. 

 long, 3-lobed, the apical lobe much the largest, 3 mm. long and broad, 

 rounded, blunt and emarginate, lateral lobes nearly half round, minutely 

 toothed, obliquely erect. Column rather stout, 2.5 mm. long, apex mi- 

 nutely crenulate, about midway in front a membranaceous protuberance. 

 Fruit not seen.
