5. A. stanfordiana Parry is related to A. patula Greene on 

 the one hand and to A. manzanita Parry on the other. Its root- 

 system is rather superficial like that of A. manzanita, and it does 

 not form heavy or globose root-crowns as does A. patula. It is 

 distinguishable from A. manzanita by its smaller size, more erect 

 habit, glabrous leaves and usually glabrous rachis and by the re- 

 moter bractlets of the raceme. It favors the mountain summits and 

 higher ridges of the central North Coast Ranges, and thus com- 

 monly grows at higher altitudes than A. manzanita, though not 

 found beyond the horizontal range of that species. It is remarkable 

 for its clean trim habit. The leaves are just alike on both sides. 

 The small berries are very irregular in shape, as if without definite 

 form, or typical only in deformation. A few individuals of it have 

 recently been discovered on Mt. Diablo, about half-way up the 

 south slope.

6. A. elegans Jepson, though collected three decades since, is 

 still known only by the original collection. It is not related to A. 

 manzanita but is near A. stanfordiana in character of foliage and 

 branchlets.
