flowered, about equalinj^ the petioles, the short pedicels 

 subtended by nearU' orbicular scarious bracts; calyx whitish, 

 pink-tinged, fineK' i)ul)escent without, 4 5 mm. long, the 

 narrowh' oblonji; lobes 3 4 mni. lon.u; petals white, (jblonj^- 

 spatulate, 1.5 mm. lone;, a little surpassed 1)\' the stamens; 

 berry glabrous, dark red, 5-6 mm. in diameter. 



Type William Sherwood 407, collected 5 miles west of 

 Imnaha, Wallowa Co., Ore., May 30, 1923. Also collected by 

 W. M. Gorman 5816, who reported it common on rocky slopes 

 and cliffs, Crooked River, Ore., June 11, 1922. Most nearly 

 related to R. velntiniim Greene but differing in the scantier 

 pubescence, more slender spines, more slender petioes, longer 

 and narrower cahx lobes and wholly glabrous fruit, and particu- 

 larh" the much narrower leaf-lobes with broad sinuses. 



' Lathyrus rigidus White var. pilosellus var. nov. Differs 

 from the species in ha\'ing the under surface of the leaves 

 thinly soft pilose, and the flowers smaller, 10-12 mm. long. 



Type Peck 7869, summit of Horse Mt., 11 miles southeast 

 of McKenzie Bridge, Lane Co., Ore., July 1, 1914. 



^ Hydrophyllum Thompsoni sp. nov. Stems erect, stoutish, 

 more or less branched below, 1.5-4 dm. high, retrorsely pubes- 

 cent; leaves appressed puberulent, ovate or oblong in outline, 

 5-10 cm. long, 5-7 parted, the divisions mostly cleft, the 

 segments lanceolate or oblong, mucronate; petioles, except 

 the uppermost, longer than the blades with spreading pubes- 

 cence; peduncles elongated, erect, equaling or overtopping the 

 leaves; inflorescence densely congested, spherical, sometimes 

 looser; calyx lobes narrowly oblong, very hispid, about half 

 as long as the corolla; corolla bright blue, narrowly campanu- 

 late, 7-8 mm. long, the lobes equaling the tube; filaments 

 glabrous. 



Type Peck 7782, collected near Multnomah Falls, Multno- 

 mah Co., April 8, 1914. J. W. Thompson 798 from near Bonne- 

 ville, Columbia Gorge, matches the type. The species differs 

 from H. capitatum, its nearest relative, in the narrow leaf- 

 segments and the elongated, stiffly erect peduncles. The habitat 

 of damp shady slopes is also very different from that of H. 

 capitatum. This adds one more species to the interesting 

 assemblage of forms nearly or quite confined to the Columbia 

 Gorge.
