RvDUERG : The American Species of 



acuminate, light green, about equalling the flowers : these greenish, 

 about 1 5 mm. long : upper sepal broadly ovate, about 5 mm. 



long ; lateral sepals about 7 mm. long, 

 oblong-lanceolate : petals narrowly lan- 

 ceolate, acute ; lip linear, about 8 mm. 

 long, thick ; spur filiform, about i cm. 

 long. (Fig. 22.) 



This is nearest related to L. sparsi- 



flora, but the spike is shorter and denser, 



the upper sepals and petals larger and the 



bracts shorter and broader, and light 



colored. The type was growing at an 



altitude of about '2600 mm.

Limnorchis laxiflora sp. 



nov. 



Stem slender, 4-6 dm. high : lower leaves oblanceolate, obtuse, 

 8-10 cm. long, 1-1.5 cm. wide ; the upper linear-lanceolate, acute: 

 spike very slender and lax, 1-2 dm. long, few- 

 ilowered ; bracts linear-lanceolate, usually 

 equalling or shorter than the flowers : these 

 greenish, 10-12 mm. long : upper sepals broadly 

 obovate, obtuse, about 4 mm. long ; lateral 

 ones broadly lanceolate, acutish : petals almost 

 equalling the upper sepal, lanceolate ; lip 

 linear, obtuse, about 6 mm. long ; spur about 

 8 mm. long, slightly clavate, a little longer 

 than the lip. (Fig. 23.) 



This is closely related to and has been mis- 

 taken for L. sparsijiora, which, however, has larger flowers, longer 

 spur, not at all clavate, longer bracts and more slender stem.
