ORCHIDACEiE 



imbricating sheaths of the new growth, terminal, rigid, exceed- 

 ing the leaves of the mature pseudobulb. Raceme loosely and 

 approximately twenty-flowered, 1 dm. long. Bracts of the inflo- 

 rescence ±2 cm. long, elliptic-oblong, obtuse, glumaceous, ner- 

 vose, soon deciduous. Flowers about 11 mm. long, distichous, 

 yellowish or brownish, rather fleshy. Pedicel slender, ovary 

 three- wdnged, together with the pedicel about 8 mm. long. Lat- 

 eral sepals about 1 cm. long, oblong-elliptic, acute, strongly con- 

 cave, the tip thickened. Dorsal sepal similar, but weakly if at all 

 carinate. Petals about 1 cm. long, linear-oblong, obtuse, three- 

 nerved. Labellum 8-10 mm. long, three-lobed, produced at base 

 into a small, coriaceous, hemispherical sac 1.5 mm. deep; lateral 

 lobes 3—4 mm. long, less than 1 mm. wide, ascending or erect, 

 similar to the petals but much shorter, rounded at the apex ; mid- 

 dle lobe about 6 mm. long, 5 mm. wdde across the dilated apical 

 half, cuneate above the lateral lobes, retuse-apiculate at the 

 rounded tip, nerves prominent. Callus above the opening of the 

 sac, hippocrepiform-cucuUate, adherent to the disc between the 

 lateral lobes and in part decurrent on them. Column slender at 

 base, dilated above to form an inconspicuously three-lobed, den- 

 ticulate or lobulate, terminal, flabellate wing, the lateral lobules 

 much reduced, obtuse. Rostellum lightly emarginate. Anther 

 cordate. Pollinia four, flattened. (Plate 87.) 



In the specimens of Clemens 268 the leaves are oblong-lan- 

 ceolate, about 25 cm. long, 2 cm. wide. Vegetatively the plants 

 are quite unlike the type, but in the structure of the flowers — al- 

 though the free ends of the callus are elongated — clearly refer- 

 able to it. 



Kamborangah, Clemens 210 (Type), November 1915; Clemens 111^ 

 November 1915. Flower salmon. Marei Parei Spur, Clem£ns39o, Decem-
