Oss. Characteres hujus tribus certissimi transitionem ex- 
hibent a Vandeis in Malaxideas. Pollinia in illis caudieula 
sepius simplice glandulaque colligantur ; in Epidendreis colli- 
gatio fit imperfecta, caudicula dividitur, glandula deest; in 
Malaxideis caudicula et glandula semper omnino desunt, et 
pollinia v. omnind sunt libera, v. materie pulverea apicibus 
tantim coherent.
