Slender, about 3 dm. high : leaves oblong to lanceolate, 5-10 cm. long, cm. wide, the lower obtuse, the upper acute : spike slender and lax, about i dm. long ; bracts lanceolate the lower slightly exceeding the flowers : these white, 10-12 mm. long : upper sepal broadly- oval, about 4 mm. long, the lateral ones linear-lanceolate, acute : petals linear-lanceolate ; lip linear, obtuse, 6—7 mm long ; spur clavate, only slightly 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 i dm. lone; 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 any respect except that the flowers are smaller and the spur is longer and more
