Dr. H. M. Hall has pointed out (Univ. Calif. Publ. Bot., vol. 4, p. 

 196. 1912) some of the numerous intergrades between typical A. cam- 

 panidatum and the dwarf form of the higher mountains, which was 

 described by Watson as A. Bidwelliae {I.e.) and has shown that it is 

 impossible to maintain the latter species distinct. Among the speci- 

 mens cited above, those marked * are of the dwarf form.
