The median stigma rudimentary or foi-ming the rostellum. The subdivision of this great group was based by Lindley* solely on characters derived from the anther, the pollen or pollen- distributing apparatus. He recognised six tribes as follows: A. Pollen masses icaxy. a. Xo caudicle or separable stigmatic gland ... 1. Malaxideae. h. A distinct caudicle but no separable gland ... 2. Epidendreae. c. A distinct caudicle (or stipes) and a separable gland ... ... ... ... ... ... 3. Vandeae. B. Pollen powdery, gramdar^ or sectile. a. Anther terminal, erect ... ... ... ... 4. Ophrydeae. b. Anther terminal, opercular 1 ... ... ... 5. Arethuseae. c. Anther dorsal ^ 6. Xeotteae. 1 "The anther is hinged to the column upon the end of which it is placed transversely like a ; 2 "Hinged to the column but stationed at its back so as to be nearly parallel with the stigmatic ;.
