CESTICHIS ELMERI 



Cestichis Elmeri, 8/9. nov. Rhizoma diu repens. Pseudo- 

 bulbi pyriformes, remoti. Folium lineari-oblongum, acutum. 

 Sepala ovato-lanceolata, acuta, carinata. Petala linearia, sub- 

 acuta. Labellum 7 mm. longum, sub-orbiculare, basi cuneato, ad 

 basim callo cucullato instructum. Columna brevis, ad imum com- 

 planata, apice incrassata. Anthera antice rotunda. 



Roots fibrous. Pseudobulbs pyriform, about 3 cm. apart, 

 1.5-2 cm. long, sheathed by triangular-lanceolate bracts. Bracts 

 of the new shoots distichous, acuminate, acute. Rhizome 3 mm. 

 thick. Leaves narrowly oblong, attenuate below, 14-20 cm. long, 

 9-11 mm. wide, deciduous, articulated, with the elongated persis- 

 tent base. Peduncle compressed, strongly winged, shorter than or 

 equalhng the leaves, ebracteate. Inflorescence distichously bracted. 

 Bracts conduplicate, carinate, 6-7 mm. long, acute, from 2 to 4 mm. 

 apart, not contiguous. Pedicels slender, about 9 mm. long. Lat- 

 eral sepals ovate-lanceolate, acute, carinate, 7-8 mm. long. Upper 

 sepal similar. Petals Hnear, sub-acute, about 7 mm. long, slightly 

 shorter than the upper sepal. Lip 7 mm. long, orbicular from a 

 cuneate base, apiculate, on each side near the base a slight thicken- 

 ing or protuberance, posterior to which is a conspicuous somewhat 

 cucullate appendage. Column 3 mm. long, broad, complanate. 

 Anther rounded in front, not emarginate. Fruit an ellipsoidal 

 or somewhat pyriform capsule, 13 mm. long. 



This species is readily distinguishable from C. Merrilli by its 

 very different lip, which is orbicular-apiculate, by its non-emargi-
