 seeded stone in a lldti lyidl). ■ — Xylococcus. {Xi/lococais, Kutt.) 



7. A. glauca, Lindl. Erect, 8 to 20 feet high, much branched (from a trunk 

 sometimes a foot in diameter at the base), completely glabrous, glaucous : leaves 

 rigid, varying from oblong to round-ovate and slightly cordate, vertical by a twist 

 of the i)etiole, vv^ith or without a small mucronate tip : racemes panicled : bracts, &c., 

 as in the preceding : pedicels slender and minutely hirsute-glandular : filaments 

 somewhat ciliate at base : fruit red, large ; the 5-celled stone half an inch in diam- 

 eter. — Lindl. Ijot. Keg., a brief character in a note under t. 1791. 



Dry liills, from Monterey {Douglas) to San Diego {Cleveland, &c.). This Great-hcrricd Manza- 

 nifa is hardly to 1"' distiiii^uislied in flower from the large and glaucesent form of the preceding, 

 except hy the gLnidulai ]ii(li(cls. But the fruit is far larger, oftener three fourths of an inch in 

 diameter; the nutlets cuuiplctely consolidated into a globose woody stone, of great thickness and 

 solidity ; the five cells all towards the centre, each with a fertile seed. While very like the pre- 

 ceding in aspect, it is associated with the next hy the fruit. 



8. A. bicolor, Gray. Erect, 3 or 4 feet high, leafy only at the end of the 

 branches : leaves ovate-oblong or oval, thinnish-coriaceous, entire, pinnately veined, 

 soon glabrous above and shining, whitish-tomentose beneath, as also the branchlets 

 and the ovate chartaceous bracts of the short spicate raceme : calyx of 5 nearly dis- 

 tinct round-ovate imbricated sepals, somewhat colored : corolla urceolate, rose-color 

 or tinged with red : hlaments scarcely dilated at base : style long : stigma capitate.

"Near Monterey," NutUill. Near San Diego, Dr. Cooper, D. Cleveland. Flowers in March 

 and April. Leaves an inch or two long. Scaly spike or dense raceme barely an inch long. Fruit 

 the size of a pea, yellow tmuing red, the solid stone maturing 4 or 5 seeds, or by abortion only 

 one. 



§ 3. Druj)e with a riranulate or ivarty surface, as in Ai'hiitus ; the cells cohering into 

 a several-celled stone. — Comarostaphylis. (Oomarostcqjhylis, Zucc.) 



9. A. polifolia, HBK. Erect, 5 to 8 feet high, glabrous : leaves linear-lanceo- 

 late, cuspidate, pale beneath : raceme elongated ; the lower bracts foliaceous, the 

 upper becoming sulndate and shorter than the slender bracteolate pedicels : calyx- 

 lobes triangular : corolla reddish : fruit dark purple, minutely warty, its stone 

 5-celled. — Nov. Gen. & Sp. iii. 277, t. 258; Torr. Bot. Mex. Bound. 108. 



Below San Diego, near the boundary, and in Mexico. Leaves 2 or 3 inches long, -willow-like. 



4. GAULTHERIA, Linn. Wintergkeen. Salal. 



Calyx 5-cleft, generally colored like tlie corolla. Corolla urceolate or campanu- 



late, 5-toothed or 5-lobed. Stamens 10, included : anther-cells opening by a hole at 



the apex, each usually 2-awned or 2-pointed. Capsule 5-celled, 5-lobed, depressed 



and umbilicate, many-seeded, enclosed at maturity in the calyx, which enlarges and 



becomes fleshy after the corolla falls, and imitates a globular berry : this is eatable 



and aromatic-flavored. Shrubby or almost herbaceous plants ; Avith broad evergreen 



leaves, and white or sometimes rose-colored flowers, mostly axillary or in axillary 



racemes, from scaly buds. 



A rather wide-spr<a<l genus, mostly American and Asiatic, none European, of temperate regions 

 or on mouiitiiiiis. Tlic original species, confined to Atlantic Noi-th America, is the well-known

1. G. Myrsinites, Hook. Very low, spreading over the ground in tufts : the 

 slender stems and blanches decidedly woody : leaves ovate or rotund (half to an 

 inch long), the margins beset with minute more or less bristle-pointed teeth : flowers 

 solitary in the axils of the leaves, on short 3 - 4-bracteolate pedicels : corolla rather
