linear-lanceolate ; lip linear, obtuse, 

 6- 7 mm long ; spur clavate, only 

 slightiv curved, a little shorter than 

 the lip. (Fig. 19.) 



This resembles L. stricta in the linear lip and the lax spike, 

 but has white flowers and slender spur. Watson confused the 

 two and following him, most authors have used the name Habc- 

 naria gracilis for L. stricta. No one who has seen Lindley's type 



could confuse the two.

Stem slender, about 3 dm. high : leaves 

 oblong-lanceolate or oblanceolate, 4-8 cm. 

 long, 1-2 cm. wide, the lower obtuse, the 

 upper acute : spike short, less than 1 dm. 

 long ; bracts lanceolate or linear-lanceolate, 

 equalling or the lower exceeding the whitish 

 flowers : upper sepal almost orbicular or 

 broadly ovate, 3-4 mm. long ; lateral ones 

 lanceolate, obtuse : petals lanceolate, acute ; lip linear, about 6 

 mm. long, obtuse ; spur filiform, curved, almost equalling the lip. 

 (Fig. 20.) 



This is closely related to L. gracilis, and differs scarcely in an y 

 respect except that the flowers are smaller and the spur is longer 

 and more slender. It was described from specimens collected by
