Lip 3-lobed, with erect or spreading side-lobes, or undivided. 35 35. Lip fringed. Anther-cells approximate and parallel.--Species 2. South Africa. =Bartholina= R. Br. Lip entire or crenate. Anther-cells divergent.--Species 20. The tubers yield medicaments (salep) and mucilage. (Including _Gennaria_ Parl., under _Habenaria_ Willd.) =Platanthera= L. C. Rich. 36. Lip 3-lobed. Column with 2 basal staminodes. Basal appendages of the pollen-masses very short.--Species 3. South Africa and southern East Africa. =Stenoglottis= Lindl. Lip undivided. Column without distinct staminodes.--Species 2. Madagascar and Mascarenes. _Arnottia_ A. Rich. 37. (1.) Pollen-masses soft, granular. Anthers usually persistent and withering. Inflorescence terminal. Leaves rolled up in the bud, with overlapping edges. Usually terrestrial herbs. [Tribe NEOTTIEAE.] 38 Pollen-masses firm, waxy. Anthers usually deciduous. Inflorescence lateral, more rarely terminal, but then leaves folded lengthwise in the bud. 55 38. Anther erect and greatly exceeding the rostellum, or inclined and incumbent upon the rostellum. Pollen-masses granular or powdery. Rostellum not distinctly notched after the removal of the pollen-masses, or not distinctly cohering with them. 39 Anther about equalling the rostellum, erect, rarely incumbent, but then pollen-masses divided into a number of large angular sections. Rostellum usually distinctly notched after the removal of the pollen-masses. 47 39. Lip distinctly articulated into 2-3 portions placed one behind the other. Anther erect.
