Box.— Vol. II.] EASTWOOD— PACIFIC COAST RIBES. 245 



V 5. Ribes hittellianum, sp. nov. 



Plate XXIV, Figs. 6« and (ib. 



Erect shrub with spreading branches, 2-3 feet high; bark smooth, un- 

 armed, gray-brown, shreddy on the younger branches. Leaves three- to 

 five-lobed, orbicular, reniform or truncate at base, 3-4 cm. wide, 2-3 cm. 

 long, irregularly dentate and somewhat revolute, rugulose veiny, glabrous on 

 both sides but with some scattered glands on the lower; petioles about as 

 long as the blades, sparingly tomentose and glandular; stipular dilation 

 broad, truncate, membranous, as wide on each side as the petiole. Racemes 

 1-2 cm. long, at first erect, later nodding, but with the pedicels erect; flowers 

 three to eight, crowded, subtended by deciduous bracteoles. Calyx tubular- 

 campanulate, with the tube i mm. long, the divisions rose-color, oblong, 

 obtuse, 4 mm. long, 2 mm. wide. Petals white, narrowly oblong, three- 

 fourths as long as the sepals and one-half as wide. Stamens with subulate 

 filaments, half as long as the sepals; anthers orbicular. Stigmas two, capitate; 

 ovary and immature fruit clothed with stipitate glands. 



This species belongs in the group of which R. nevadense 

 Kellogg is the type. It differs from that species in the 

 inflorescence and the shape of the floral organs. 



Collected near the head-waters of Canon Creek, Trinity 

 County, California, not far from Twin Lakes, July 9, 1901, 

 and named in honor of Mr. Carlos T. Hittell, one of the 

 party on a trip to these little known mountains. 



6. Ribes glaucescens, sp. nov. 

 Plate XXIV, Figs. 7a and ^b. 



Unarmed shrub with older bark gray-brown, younger bark bright brown 

 glossy, shreddy. Leaves three-lobed, orbicular-reniform, about 3 cm. long, 

 3-5 cm. wide, irregularly dentate, glabrous except for some minute glands on 

 the lower surface, glaucescent, paler on the lower surface; petioles about as 

 long as the blade, minutely puberulent, with the stipular dilation on each side 

 narrower than the petiole, and sparingly fringed with glandular hairs. Inflor- 

 escence in fruit spreading or erect, generally shorter than the leaves, rather 

 loosely flowered with from five to ten flowers; peduncles as long as the raceme, 

 striate, puberulent; pedicels slender, becoming 5 mm. long, shorter than the 

 brown, membranous, gland-tipped bracts. Flowers subtended by two small, 

 deciduous, reddish bracteoles. Calyx open-campanulate, with very short 

 tube, and spreading divisions; these rose-color, oblanceolate, 4 mm. long, 

 1.5 mm. wide, glabrous. Petals white, spatulate two-thirds as long as the 

 sepals, denticulate near the apex. Stamens half as long as the sepals, with 

 suborbicular anthers and broad filaments. Ovary glabrous except for the 

 scattered stipitate glands.
