63. Leaves not jointed. Lip more or less distinctly clawed. Column slender.--Species 30. Tropical and South Africa. =Liparis= L. C. Rich. Leaves jointed between sheath and blade. Lip not distinctly clawed. 64 64. Stem with pseudobulbs. Leaf-blade horizontally flattened.--Species 1. Mascarene Islands. (_Cestichis_ Thouars, under _Liparis_ Rich.) =Stichorchis= Thouars Stem without pseudobulbs. Leaf-blade placed vertically, fleshy. Lip uppermost, concave at the base.--Species 1. Tropics. =Oberonia= Lindl. 65. (55.) Leaves with convolute praefoliation (i.e. rolled lengthwise in the bud, one edge overlapping the other). Stem not swollen, or several joints of the stem equally thickened. Mostly terrestrial herbs. 66 Leaves with conduplicate praefoliation (i.e. folded together along the midrib in the bud, their edges being applied to each other without overlapping). Mostly epiphytic herbs. 73 66. Pollen-masses 2-4, without appendages, attached to the glands of the rostellum by a stalk produced from the latter. Leaves usually jointed. [Tribe CYRTOPODIEAE.] 67 Pollen-masses 8, appendaged, without a stalk produced from the rostellum. Leaves usually continuous. [Tribe PHAIEAE.] 71 67. Lip produced into a spur or pouch at the base. 68 Lip without a spur or pouch. 69 68. Sepals narrower and less coloured than the petals, usually reflected. Petals erect or spreading.--Species 90. Tropical and South Africa. Some are used as ornamental plants. =Lissochilus= R. Br. Sepals and petals equal or nearly so, spreading.--Species 130. Tropical and South Africa. Some species yield medicaments (salep) and mucilage or serve as ornamental plants. (Including _Cyrtopera_ Lindl. and _Orthochilus_ Hochst.) =Eulophia= R. Br. 69. Column with 2 basal lobes projecting upon the base of the lip.--Species 4. East Africa. =Pteroglossaspis= Reichb. fil. Column without appendages. 70 70. Lip and lateral sepals inserted on the foot of the column, the former with a narrow, the latter with a broad base.--Species 1. Madagascar. =Eulophiella= Rolfe Lip inserted on the foot of the column, the lateral sepals on the margin of the ovary, both with a narrow base.--Species 1. Madagascar and Mascarene Islands. The pseudobulbs yield mucilage. =Cyrtopodium= R. Br. 71. Leaves jointed at the upper end of the sheath. Inflorescence 2-3-flowered. Lip slightly saccate. Column rather long, with short, roundish wings. Pollen-masses affixed to a single appendage.--Species 2. West Africa. Used as ornamental plants. (Under _Pachystoma_ Reichb. fil.) =Ancistrochilus= Rolfe Leaves not jointed. Inflorescence usually many-flowered. Lip clasping the column or adnate to it, usually spurred. 72 72. Lip adnate to the column; blade spreading, 3-4-lobed. Column short.--Species 9. Tropical and South Africa. Some are used as ornamental plants. =Calanthe= R. Br.
