j 2 IN TK ODVC TION. 



on and entirely adnate to the face of the stigma, erect or re- 

 clined. Pollen cohering into a great number of coarse grains, 

 which are all fastened by elastic and cobwebby tissue into one 

 large mass and to a stalk that connects it with a gland or viscid 

 disk which was originally a part of the stigma. Flower in our 

 species ringent, the lip with a spur beneath : one distinct gland 

 to each pollen-mass. 



Genus I.— Orchis. The two glands, or viscid disks, enclosed 

 in a common pouch. Sepals and petals nearly equal, all (in 

 our species) converging upwards and arching over the column. 

 Anther-cells contiguous and parallel. I or 2 leaves at base of 

 scape. Root of fleshy fibres. A spike of several flowers. 

 O. spcctdbilis, 0. rotundifblia. 



2. Habenaria. The two glands or disks naked (without 

 pouch or covering), either approximate or widely separated : 

 otherwise nearly as in true Orchis : the lateral sepals, however, 

 mostly spreading. Scape I or 2 leaved at base, or with leafy, 

 bracted stems. Root a cluster of fleshy fibres, or tuberous 

 thickened. A close or open spike of numerous flowers.

Tribe II. NEOTTIE^. Anther dorsal and erect or in- 

 clined, attached by its base only or by a short filament to the 

 base or summit of the column, persistent. Pollen in our genera 

 loosely cohering (mostly by some delicate elastic threads) in 

 2 or 4 soft masses, and soon attached directly to a viscous 

 gland on the beak of the stigma. 



3. Goodyera. Lip entire, free from the column, without cal- 

 losities at the base ; sac-shaped, sessile. Otherwise as in Spiran- 

 thes. Leaves clustered at base of scape. Root of thick fibres. 

 A spike of numerous small flowers.
