CALIFORNIAN MANZANITAS. 491 



tion. Notwithstanding variation in habit, and degree of 

 pubescence, shape of leaves, etc., it is readily distinguished 

 in the field, forming usually a low spreading bush, with dull 

 green foliage, hispidly ciliate young branches, and very con- 

 spicuous floral bracts, occasionally becoming foliaceous, and 

 generally exceeding the hairy pubescent pedicels, both the 

 ovar}^ and forming fruit are more or less hairy pubescent, 

 but not glandular. It is usually later in flower than other 

 species with which it is frequently associated, thus obviating 

 a confusion that is likely to arise from hybridization. The 

 fruit maturing in August shows the usual character of nut- 

 lets, more or less separable or coalescent. Specimens from 

 Southern California and Arizona, extending into Mexico 

 (one of which is characterized below as A. Pringlei), here- 

 tofore referred to this species, are clearly distinct.

Shrubby to sub-arborescent, 5 — 25 feet in height, bark 

 smooth, dark reddish brown, renewed annually, younger 

 branches more or less closely pubescent; leaves petiolate, 

 about one-third the length of the blade; smooth, dull green 

 on both sides, entire, varying in shape from narrowly to 

 broadly ovate, usually obtuse at the apex, and abruptly 

 short mucronate, rounded or tapering at the base; inflores- 

 cence paniculate, the divisions more or less prolonged, 

 rachis hoary -pubescent, and thickening upwards, bracts 

 broad, acuminate, rigid and persistent, externally pubes- 

 cent; pedicels smooth, exceeding the bracts, calyx with 

 broad orbicular segments, corolla broadly urceolate, sta- 

 mens with slightly bearded filaments, style included; fruit 

 smooth, irregularly orbicular, 4 — 6 lines broad, 3 lines high, 

 dull white at early maturity, becoming reddish-brown with 

 age, nutlets irregularly coalescent, usually one or more 

 broader, with 3 fertile cells, with intermediate 1-celled nut- 

 lets, more sharply carinate, the whole including 5 — 7 fertile 

 cells.
