Ames New Species of Acoridium from the Philippines. 149 



spread out. Lateral sepals ovate, obtuse, 3-nerved, 4.5 mm. long. Upper 

 sepal elliptic-oblong, 4 mm. long. Petals 4 mm. long, 2.5 mm. wide, 

 obovate, suborbicular, 3-nerved. Lip 3-lobed, from base to tip of mid-lobe 

 1-1.5 mm. long; lateral lobes falcate, obtuse; middle lobe quadrate, 

 rounded at the angles, with a tooth or mucro at the apex. At the base of 

 each lateral lobe is a thickened callus-like plate, and near the middle of 

 the lip a small tubercle.

Acoridium recurvum is most nearly allied to A. pumilum Rolfe, although 

 much larger in foliage, and quite different from it in habit. The flowers are 

 fleshy, nearly opaque, and red-brown when dry. The recurved pseudo- 

 bulbs, which arise from a creeping branched rhizome, and the densely 

 spotted sheaths, which clothe the immature pseudobulb and conceal the 

 petiole and leaf-base, are characters which distinguish this species clearly 

 from all other species of Acoridium thus far discovered in the Philippine 

 Islands. 



Acoridium philippinense sp. nov. 



Pseudobulbi pyriformes ; folia oblongo-lanceolata, 5-nervia ; sepala lat- 

 eralia oblongo-lanceolata, acuta, 3-nervia ; petala rhombiformi-ovata, 3- 

 nervia; labellum 3-lobatum, ecallosum, lobis lateralibus lineari-lunatis, 

 obtusis, quam lobo medio minoribus, lobo medio oblongo, obtuso. 



Pseudobulbs 2 cm. long, somewhat pyriform, monophyllous. Sheaths 

 inflated, nigro-punctate when dry, round, acute at the apex. Petiole 5-6 

 cm. long, slender. Leaf oblong-lanceolate, acute, strongly 5-nerved, 8.5- 

 11 cm. long, 16-23 mm. wide, broadest above the middle. Peduncle shorter 

 than the petiole and leaf, or longer, 12-16 cm. long, slender. Inflorescence 

 5-10 cm. long, 1 cm. through. Flowers in a dense raceme, about 2 mm. 

 apart. Bracts glumaceous, longer than the ovary, 2.5 mm. long. Flowers 

 bright yellow, emitting an odor which recalls the smell of freshly sawed 

 pine lumber. Lateral sepals oblong-lanceolate, acute, 4.5 mm. long, 2 mm. 

 wide, 3-nerved. Upper sepal similar, narrower, 4.5 mm. long. Petals 

 rhombic-ovate, acute, 3-nerved, 3.5 mm. long, 2.5 mm. wide. Lip 3-lobed, 

 lateral lobes linear-crescent shaped, obtuse, erect, 1 mm. long, much nar 

 rower than the broad oblong-lingulate middle lobe, which is trulliform 

 when not flattened out, blunt at the apex and thickened at the base. Col 

 umn exalate, 9 mm. long, stout, fleshy ; apex rounded. 



From between Suyoc and Panai, Prov. Benguet, Luzon, alt. about 6,500 

 ft., epiphyte, November 7, 1905, Elmer D. Merrill (No. 4757). 



This very distinct species belongs to a group of odd forms which appear 

 to have equal affinity with the sections Platyclinis and Euacoridium. 



Acoridium turpe sp. nov. 



Pseudobulbi pyriformes; folia oblongo-lanceolata, acuminata, acuta; 

 sepala lateralia ovato-lanceolata, acuta; sepalum dorsale oblongo-ovatum, 

 obtuse ; petala ovato-acuta, 3-nervia ; labellum 3-lobatum, lobis lateralibua
