BOTANY OF THE GOOSEBERRIES 457 



described it* as having a "rich, subacid, vinous, rather perfumed 

 flavor, which is extremely agreeable." 



Found in the northwestern portion of North America. 



15. E. DIVARICATUM, Dougl. (Fig. 87.) 



Stems clustered, branches widely spreading, 5-12 feet (15-35 

 decimeters) long, nearly glabrous; thorns stocky, mostly single; 

 leaves shining, minutely pubescent, roundish, 3-5 lobed, the lobes 

 incisely toothed on long slender petioles ; mostly less than 1 inch 

 (25 mm.) in diameter; peduncles long, 2-4-flowered; pedicels 

 slender and drooping, half an inch (12 mm.) long, with a small, 

 broad bract at base; flower %-% inch (10-13 mm.) long; calyx 

 livid purple, [slightly greenish without; petals white or purple - 

 tinged, fan-shaped, the margins convolutely overlapping; fila- 

 ments and 2-cleft villous style longer than the calyx lobes; an- 

 thers very short and broad, mostly in pairs; ovary smooth; berry 

 small, glabrous, dark purple or black, agreeable. 



Found from California to British Columbia, the variety extend- 

 ing eastward to the Eocky Mountains. 



This species might well receive attention from horticulturists. 

 The bush is comparatively free from thorns, the fruit of good 

 size, fine flavor and perfectly smooth. 



Covillef bases a variety E. oxyacanthoides var. saxosum, Hook., 

 on the following characters: "Petioles usually with a few long, 

 spreading, large, but rather flexuous, bristle-like hairs on the 

 margins near the base, otherwise glabrous; leaves with a broad 

 but well-marked sinus at the base, glabrous on both sides." This, 

 I think, is a form of JR. divaricatum. 



16. E. ROTUNDIFOLIUM, Michx. (Fig. 88.) 



Low shrub, much resembling R. gracile; branches commonly 

 straight, with light colored bark; thorns mostly single, but very 

 short, gray, like the outer bark; leaves wedge-shaped, deeply 3-5 

 lobed, smooth or slightly downy, ciliate on the margins and veins, 

 petioles pubescent, the hairs sometimes glandular-tipped when 

 very young, peduncles short, 2-3-flowered, rather slender like the 

 pedicels ; calyx lobes narrow or oblong, greenish or dull purplish, 

 much shorter than in B. gracile, apparently seldom reflexed ; petals 

 obovate, small, filaments longer than the calyx lobes, style 2-cleft, 

 villous; berry small, smooth, agreeable.
