20G cxxxiii. ORCHiDEJE (rolfe). [Fodandria. 



lobe linear-subulate, with incurved apex ; side lobes short and broad, 

 with bidentate apex. 



A West African monotype, somewhat resembling Mahenaria in habit, but remark- 

 able for its enormously elongated anther and long narrow segments. The stigma 

 resembles Platanthera, but is guarded on either side by the enlarged side lobes of the 

 rostellum, which are free from the anther channels.

 PI. iii. 624, in part. 



Sepals unequal, free; lateral more or less spreading or reflexed. 

 Petals simple or deeply bilobed, usually narrower than the dorsal 

 sepal, and appressed to it, forming a galea, or the posticous lobe so 

 appressed, and the anticous descending, and simulating a lobe of 

 the lip. Lip continuous with the column, often shortly adnate to it, 

 produced at the base into a short or much elongated spur ; limb 

 spreading or pendulous, narrow or broad, undivided or trilobed ; side 

 lobes sometimes fimbriate or pectinate. Column short, footless ; 

 clinandrium erect, short or scarcely as long as the anther. Anther 

 cells parallel or diverging; apex inferior, short and adnate or free, 

 elongate, and horizontal, or descending in slender channels on the 

 margins of the side lobes of the rostellum ; polHnia granular, with 

 short or elongate caudicles, and exserted, naked gland ; staminodes 

 lateral, small, rounded or auriculate. Stigma bilobed, or extended into 

 two short or elongate, often clavate, papillose processes ; rostellum 

 trilobed ; middle lobe subulate or tooth-like, situated between the 

 anther-cells ; side lobes much longer, and acting as carriers for the 

 caudicles of the pollinia. Capsule elHpsoid or oblong, sometimes
