Arctostaphylos nummularia Gray. 



This is distinct and can not be mistaken for any other 

 species. It is in bloom at some place on the mountain 

 throughout the year. It rarely grows amid dense brush, 

 seeming to prefer somewhat exposed situations, and usually 

 attains a height of about two feet, seldom more than four. 

 It is quite common and always conspicuous, with young 

 stems erect and slender, invested with a halo of white hairs, 

 flowers small and very abundant, and leaves round and 

 shining. The fruit, which is flattened longitudinally and 

 without the mealy pulp of other manzanitas, differing also 

 in the deciduous pericarp, which at maturity leaves the nut- 

 lets naked, sets this apart from all other species and renders 

 the name of manzanita, or little apple, inappropriate when 

 applied to this species. 



Arctostaphylos glandulosa, sp. nov. 



Shrubby, never arborescent, 2-8 feet high, young branches straight and 

 erect, older ones divaricate; young shoots glandular-hirsute, with long and 

 short spreading hairs; leaves erect on short petioles, oval to ovate-lanceolate, 

 mucronate, thin, bright green, or sometimes thicker and inclined to be glau- 

 cous, sometimes spinulose-dentate even on flowering stems, an inch or two 

 long, usually glandular-pubescent and glutinous; older stems smooth, dark 

 brownish red, with thicker leaves, inclined to be orbicular, often glaucous, 

 and without glandular hairs; racemes usually few in the panicles, loosely or 

 densely flowered; bracts glandular, persistent, lanceolate-acuminate, green and 

 foliaceous below, usually longer than the pedicels, shorter, often rose-colored 

 and petaloideous above; sepals orbicular, glandular-ciliate, white, membra- 

 nous, stellately spreading after anthesis, often revolute; corolla large, glabrous 

 externally, hairy within, white or pinkish; stamens with filaments densely 

 bearded but not glandular; style shorter than or equalling the corolla; ovary 

 flattened horizontally, densely covered with white hairs more or less tipped 

 with rose-colored or white glands; fruit spherical, horizontally flattened, 

 transverse diameter about i cm., vertical diameter 5-7 mm. The immature 

 but fully grown fruit is often tinged with red on one side; when ripe it becomes 

 reddish brown, with the mealy pulp quite abundant. Sometimes it has a 

 purplish bloom, and is generally slightly hairy and glandular. The pyrenae 

 are variously coalescent and frequently united into one. 



This is the manzanita earliest in bloom on the mountain, 

 the most beautiful, the most fragrant, most variable, and 

 most widely spread. On the upper slopes and towards the
