XX. GYNANDRIA\ 



1. MONANDRIA. 



* Anther adnate, nearly terminal, persistent. Pollen mass, composed 

 of angular granules elasticaUy cohering, fixed by its base. Br. 



1. Orchis. Cor. ringent. L/p spurred on the inider side at 

 the base. Glands of the stalks of the pollen viass (1 — 2) 

 contained in one common little pouch. Br. 



2. Gymnadenia. Cor. ringent. Lip spurred at the base be- 

 neath. Glands of the stalks of the pollen mass nalced, ap- 

 proximate; Br. 



3. Habenaiii.\. Cor. ringent. Lip spurred on the under side 

 at the base beneath. Glnnds of the stalks of the pollen 

 mass naked, distinct, with the cells of the footstalks adnate or 

 separated. Br. (This character seems too near that of t!ie 

 last genus.)
