OBCHIDS OF MADAGASCAR 461 



broad bar runs down the centre, but there are no callosities. 

 The column is almost straight, but slightly curved in the base, 

 the wings flanking the stigma. The anther is provided with a 

 rather long green beak.

This is allied to L. ornithorrhynchos, differing in the longer 

 basal portion of the stem covered with whitish membranous 

 sheaths, the oblong lip with crenulate edge, and the curved 

 slender column. The flowers are olivaceous green. The narrow 

 dorsal sepal is 8 lines, the laterals 7 lines, and the lip 5 lines 

 in length.

 caulem amplectentibus, ovario ferme tequalibus ; sepalo postico 

 lineari, lateralibus oblongis quam labellum longioribus ; petalis 

 linearibus quam sepalum posticum augustioribus ; labello basi an- 

 gustato longo, lamina abrupte deflexa oblonga truncata ; columna 

 brevi curva crassiuscula.

This plant differs from L. ornithorrhynchos, to which it is 

 closely allied, in the bulbous base of the stem and short rhizome, 

 the more numerous leaves, 4 inches in length by 2 inches in dia- 

 meter, and the shape of the lip, which has a rather long narrow 

 base and an oblong truncate lamina which is abruptly deflexed. 

 The flowers are olivaceous ochraceous, the lip having a dark 

 ochreous patch in the middle of the lamina. I have only seen a 

 very good coloured drawing of this plant made by Deans Cowan.
