This is doubtless the S. uncinata of De Candolle ; but not, I 

 think, of Willdenow. I may here remark, that the reticulate- 

 leaved species (/$. uncinata, Torr. & Gr.) is the Leptoglottis 

 of De Candolle (" Mem Legum "), as I have ascertained from 

 a fragment of the original specimen in the rich herbarium of 

 Mr. AVebb, which that gentleman obligingly sent me ; but I 

 find no neutral flowers or sterile filaments in the numerous 

 specimens of this plant, from different localities, which I have 

 from time to time examined.
