 usually with a conspicuous one-sided furrow. 



Mountains east of San Diego; C. B. Orcutt. No. 543;

Ten to twenty-five feet in height, branching from the base, 

 with a trunk often more than one foot in diameter, branches 

 and young shoots smooth throughout; leaves glaucous green 

 finely net-veined, short petiolate, with a conspicuous mid 

 nerve, ovate to broadly sub-cordate at base, either acute and 

 sharply mucronate or obtuse with an abrupt mucro, young 

 vigorous shoots frequently irregularly serrate resembling 

 those of young seedlings; inflorescence paniculate prolonged 

 with divaricate and pendent branches, bracts rigid spreading 

 more or less, net-veined the lower foliaceous, pedicels 3 or 4 

 times exceeding the bracts, glandular-viscid (much less so 

 than in A. viscida); flowers rather large, otherwise similar 

 to allied species; fruit ovate, 9 lines long, 6 lines broad, 

 resinous viscid, pericarp thin without granular pulp, stone 

 smooth, usually sharply apiculate with regular perpendicu-
