ORCHIDACEiE 



H. limosa to notes made at Paris by Eaton, consists of a single specimen 

 in bud which is unserviceable for a definitive conclusion regard- 

 ing its position in synonymy. Judging from Richard's dravi^ing 

 it may be conspecific with H. //Two^a, although it may be referred 

 also to H. volcanica with equal surety, H. Thurberi is similar 

 to H. Umosa. The type has a linear lip. It is difficult to compre- 

 hend Dr. Rydberg's treatment oiH. Thurberi. He has confused 

 it with H. dilatata var. leucostachys, and described as Limnorchis 

 Arizonica material which agrees beautifully with Gray's type 

 of ^. Thurberi.
