acutish, about half longer than the lip, less than i mm. thick. 

 Fig. 1 6.) 



Lindley describes this as having the 

 lip half as long as the spur, but I have 

 not seen any with so long a spur, not 

 even in Douglas' specimens at Kew.

Limnorchis leucostachys robusta var. nov. 



Very stout and tall, 4-10 dm. high, leafy: spike long and 

 dense, 1-3 dm. long : spur usualK' clavate, over i mm. thick, 

 obtuse, about one-third longer than the 

 lip. (Fig. 17.) 



This may be distinct from L. leuco- 

 stachys but the onl}' characters distin- 

 guishing it from the type is the thicker 

 spur and the denser spike. More field 

 work is needed in order to settle its 

 relationship to L. IcucostacJiys. The fol- 

 lowing specimens are in our herbaria :
