THE CARPEL

from the ventral veins, the distal ovules are connected with branches 

 from the dorsal bundle, and a few ovules derive their supply from a 

 meshwork of veins connected with both dorsal and ventral bundles 

 (Fig. 83). In Drimt/s, the ovules are in two submarginal rows, with the 

 ovule traces derived, in part, from the ventral bundles and, in part, 

 from anastomosing branchlets from both dorsal and ventrals. These

Fig. 83. Diagrams showing placentation transitional from laminar to submarginal as 

 shown by vascular structure. Ovules in loose, submarginal rows with traces derived 

 from dorsal and ventral bundles and from the small, connecting strands. A, B, 

 Degeneria, showing variations in ovule supply; C, D, Drimys (Tasmannia type): 

 C, lateral view of carpel; D, carpel split ventrally and spread open. For clarity, 

 ovules are omitted, small circles and black dots indicate position of micropyles; 

 dotted lines indicate position of stigmatic crest. (A, B, after Swamy; C, D, after 

 Bailey and Nast.)
