 linear, ensiform, often falcate, chartaceo-coriaceous, smooth, with carti- 

 laginous scabrous edges, the apex abrupted and with a straight and minute 

 sharp tip obliquely turning inwards, sheathed half below, 2J-6J cm long, 

 2-5 mm broad, 4r-5-nerved. Scape arising from the centre of the leaves 

 and much longer than them, erect, slender, smooth, furnished with a leaf 

 at the lower part and a slender and sheathing bract §-l§ mm in length at 

 the middle part, becoming into a spike-like raceme at the upper portion, 

 7-15 cm high including the rachis. Raceme spike-like, 1J-3 cm long. 

 Flowers small, laxly disposed, sparse, mostly solitary or sometimes geminate 

 on the rachis, or oftener interrupted. Pedicel usually short, erect, shorter 

 or often longer than the flower, 1-6 mm long. Bract only one under each
