6. Ribes parvulum (Gray) Rydb. Mem. N. Y. Bot. Card. 1: 203. 1900.

 ripe, covered with short weak gland- tipped bristles. R. lacustre parvulum. 

 Very near to R. lacustre (Pers.) Poir, a species of the cold bogs to the northward 

 and eastward of our range. R. echinatum Lindl. is a form of R. lacustre with 

 less dissected and somewhat pubescent leaves. It occurs in dryer situations, 

 mostly on wooded hillsides; in our range northwestward. 



7. Ribes coloradense Coville, Proc. Biol. Soc. Wash. 14: 3. 1901. Stems 

 procumbent, unarmed, with brown bark; the twigs pubescent and glandular: 

 leaves cordate-reniform, 4-7 cm. broad, 5-lobed, nearly glabrous but with 

 minute sessile glands; the lobes ovate-triangular: racemes 6-12-flowered, the 

 pedicels and rachis glandular and minutely pubescent: calyx-lobes spread- 

 ing, ovate, obtuse; the tube short, salverform, glandular-pubescent: petals 

 short, broad, purplish: fruit spherical, sparingly glandular-hairy, black, with 

 bloom. R. prostratum. Mountains of Colorado. 



8. Ribes Wolfii Rothrock, Am. Nat. 8: 358. 1874. Unarmed shrub, 5-12 

 dm. high, glandular-pubescent on the young branches, petioles, and pedicels: 

 leaves cordate-orbicular, thickish, 4-8 cm. broad, smooth above, paler and

 zona. 



9. Ribes viscpsissimum Pursh, Fl. Am. Sept. 1 : 163. 1814. A shrub 8-15 dm.

 and inflorescence viscid-pubescent: leaves round-cordate, shallowly 3-lobed,
