petiolate penninerved; stipules lateral; catkins axiUary; floration 

 developed before leaves. (Florida.)— See p. 242. 



10(?). Didymeles Dup.-Th. — Flowers dioecious amentaceous; 

 surrounded by braeteoles or sepals (?) ; males 2-androus; filaments 

 short erect; anthers ovate extrorse, 2-riinose. Carpels 2, opposite 

 free ; germen of eacb 1-locular, attenuate above to long recurved 

 and revolute style, longitudinally sulcate and densely plumose- 

 papillose within. Ovule 1, descending; micropyle extrorsely 

 superior; exostome far produced in tube dilated at apex. Fruit 

 consisting of drupes (?) 2, sulcate within ; seed descending ; coty- 

 ledons of exalbuminous embryo thick fleshy plano-convex ; radicle 

 superior.— A tree (?) ; leaves alternate petiolate entire penninerved 

 coriaceous ; catkins axillary and (?) terminal. {Madagascar.)— Bee

71(?) MYEICE^. 



11. Myrica L. — Flowers dioecious or more rarely monoecious 

 amentaceous ; males consisting of stamens 2-20, sessile in axil of 

 each bract or spicate, naked or surrounded by 2-co braeteoles ; 

 filaments free or connate at base; anthers extrorse, 2-rimose. 

 Female flowers sessile in axils of scales of catkin, naked at base or 

 surrounded by 2 or a few sterile or rarely fertile braeteoles (bearing 

 abortive budlike flower in axil). Germen free, l-locular; style 

 branches 2 (anterior and posterior), papillose-plumose within ; ovule 

 1, basilar or subbasilar orthotropous ; micropyle superior. Fruit 

 drupaceous ; exocarp rugose papillose and secreting a waxy matter ; 

 putamen more or less hard, 1-spermous. Seed erect; cotyledons of 

 straight exalbuminous or very scantily albuminous embryo thick; 

 radicle superior. — Small trees, shrubs or undershrubs, often odorous ; 

 leaves alternate, very rarely (Gomptonia) stipulate, penninerved, 

 entire or dentate or serrate; catkins axillary generally springing 

 from innovation, simple or compound, either 1 -sexual, or androgy- 

 nous; female flowers superior; males inferior. {All temp, and warm 

 regions.) — See p. 244.
