DEITSBdMECOX ( Greek dendron,tTee ; mecon, poppy ) . 

 The only genus of Papaverdcece known to have woody 

 stems. California. Probably only one species. D. rigi- 

 dum, Benth. Dry, rocky hills of the Coast Range, mainly 

 in the south: 3-10 ft. high : stems up to 1 in. thick:

 late, not cut, coriaceous, reticulately veined, very acute 

 and mucronate : fls. bright yellow, 1-3 in. in diam., on 

 pedicels 1^ in. long : capsules linear, nerved, 1J^-2K 

 in. long; seeds black, almost globular. Hardy in some 

 parts of England. Propagated from seeds, that take 

 very long to germinate. B.M. 5134. P. S. 14:1411. Gn. 

 50:1087. J.H. III. 29:92.-D. Hdrfordil, Kell., and D. 

 flexile, Greene, from Santa Cruz and Santa Rosa Islands, 

 are now considered as forms of above, varying mainly 

 in the habit, more drooping and graceful, and in the 

 much larger, ovate, more glaucous leaves. These differ- 

 ent forms occur also in the mountains near Santa Bar- 

 bara. Considerable variation in size of flowers appears 

 to depend mostly upon the conditions where plants are 

 growing. Outdoor shrubs. p. Franceschi.
