 green, sparingly pubescent and glandular with short-stalked glands, the under surface canescent 

 with a dense tomentum, the 3-5 lobes crenulate : racemes drooping, longer than the leaves ; 

 pedicels 2-5 mm. long, recurved in fruit ; bracts longer than the pedicels ; ovary densely tomen- 

 tose with intermingling glandular hairs ; hypanthium rose-colored, 5-7 mm. long ; sepals shorter 

 than the hypanthium; petals rounded and short-clawed; styles pubescent below; berry viscid- 

 pubescent, glaucous. 



On wooded or chaparral-covered slopes, Upper Sonoran Zone; Coast Ranges from Tehama County to 

 Santa Barbara County, California. Type locality: California. Oct.-March. California Black Currant.

 white-tomentose ; racemes 2-3 cm. long, pedicels 1-2 mm. long; bracts much longer than the 

 pedicels ; hypanthium campanulate, 3-4 mm. long, pale rose or white ; sepals shorter than the 

 hypanthium, oval ; style pubescent at base, ovary densely tomentose ; berry viscid.

 broad, bright green, moderately villous and slightly rugulose above, gray-green and densely 

 pubescent beneath; racemes 2-4 cm. long, drooping, many-flowered; pedicels scarcely 1 mm. 

 long ; hypanthium broadly urceolate, 4 mm. broad, about 1 mm. high ; sepals broadly spatulate, 

 1.5 mm. long, rotate-spreading, purple with dark purple veins; petals broadly obcuneate, trun- 

 cate, less than 1 mm. long ; berry purple to black, glandular-villous, becoming smooth in age.

2. GROSSULARIA [Tourn.] Mill. Gard. Diet. ed. 7. 1759. 



Erect or spreading shrubs, armed at the nodes with simple or 3-forked spines, or 

 rarely spineless. Racemes one- to few-flowered; bracts present; bractlets absent or if 

 present situated on the base of the pedicel. Ovary often spiny. Fruit not disarticulating 

 from the pedicel. [Name from Middle Low German, grossel-beere, meaning gooseberry.] 



A genus of about 65 species, natives of the north temperate zone. Type species, Ribes Grossularia L. 



Flowers 5-merous; petals much shorter than the sepals. 



Anthers not broader at base than at apex, usually less than 2 mm. long. 



Styles hairy toward the base; ovary not bristly, either smooth, pubescent, or beset with stalked glands. 

 Stamens about twice the length of the petals or longer. I. Divaricatae. 



Stamens equaling the petals. II. Setosae. 



Styles glabrous throughout. 



Flowers usually of some other color than deep red or purple; filaments (except in G. binominata) 

 equaling or shorter than the petals. 



Ovary not bristly, either glabrous or pubescent with weak glandless or gland-tipped hairs. 



III. Microphyllae. 



Ovary densely bristly, the bristles developing into sharp spines in fruit. 



IV. Watsonianae. 



Flowers deep red or purple; filaments twice the length of the petals or more. 



V. Lobbii. 



Anthers lanceolate to lanceolate-ovate, 2 mm. long or more. VI. Menziesii.

Stamens equaling or shorter than the extended sepals; sepals 1-2 times the length of the hypanthium. 



Hypanthium and sepals green, together 5-7 mm. long; petals white. 



Leaves glabrous on both surfaces; hypanthium and sepals glabrous. 2. G. inermis.
