AND GENERA OF PLANTS, 267 



Hab. Round Monterey, Upper California. Flowering in March and April, very much like A. 

 uva-ursi, but a low erect shrub about half a foot high, branching from the base and forming tufts. 

 Stems brown and smooth, branches villous as well as the young leaves beneath, the leaves at 

 length smooth. Flowers white, in short rounded racemes. Corolla verlicose-ovate, the border 

 reflected, densely bearded within towards the orifice. Segments of the calyx slenderly ciliale: 

 braetes linear, reflected, about the length of the villous short petioles. Awns of the anthers very 

 long and hirsate; the filaments with a few straggling hairs at the base. 



Arctostaphylos * acuta; glaucous, dwarf and erect, pubescent, leaves obovate 

 or oblanceolate, with a short acute point, at length nearly smooth, below 

 narrowed with a petiole; flowers in short terminal bracteate racemes, the 

 pedicels minutely bibracteolate at base ; corolla pubescent within; awns of 

 the anthers slenderly hirsute, about their length, filaments smooth. 



Hab. With the above, for which it might be mistaken as a variety, but the leaves are usuall)^ 

 broader, and the flowers smaller and striated with pink. 



*XEROBOTRYS. 



Arctostaphylos, but the corolla four or five-toothed. Stamens eight to ten. 

 Ovarium subglobose, the base surrounded by a thick, circular, entire nec- 

 tary. Berry globose, dry and farinaceous, containing three to five triangu- 

 lar grooved nuts, the nuts one, two or three-seeded; one, two or three-celled. 

 The cells tortuous. Seeds curved and elongated, sempervirent. — Shrubs 

 of Upper California, leaves entire or serrated; racemes contracted, terminal, 

 flowers white or rosaceous. Berries yellow, spherical, dry, juiceless and in- 

 sipid. Nearly allied to Xylococcus, but the flower that of Arctostaphylos, and 

 the structure of the fruit distinct from both. (The name from ^yi^os dry, 

 and ^orevs, a grape or herry, in allusion to the nature of the fruit.)

Hab. Monterey, Upper California; common. A bush growing in tufts about three feet high. 

 Flowers white, or with a slight rose tinge; leaves generally entire. Berries yellow, as large as 

 pepper corns, spherical and pilose, with a dry, perfectly insipid farinaceous pulp, containing mostly 

 about three obtusely three-sided nuts, with two other abortive ones, each containing two or three 

 cells, with a single elongated seed, in each filling the tortuous cavity of the nut. Our plant is 

 nearly ferruginous,
