tricolor. Note: 0. tricolor H.-Schdff. (24 i), described from South Africa; according to Hy. Edwards (in: Viet-

the anterior angle, 7 from the apex of the areola, 8 and 9 from the areola and with a long, very much 
curved footstalk, 10 from the areola near 8, 11 anastomoses shortly with 12 and extends then near 10. Hind¬
