Presence and structure of osmiophilic platelets, canaliculi, and the chondriome in spp. of the 3 genera are discussed. Modifications of the methods of Bensley, Bowen, Kolatchev, and Cajal were used on root tips and embryo sacs. All 3 structures are located just back of the apical meristem, and persist to a lesser extent in maturing cells. It is concluded that the canaliculi are definitely involved in the vacuome. No conclusions were reached as to the exact nature or function of the osmiophilic platelets or chondriome.
