HVDROPHYLLUM ALBIFRONS. 



Hydropkyllum Virginianutn Holzinger, Cont. U. S. Nat. Herb- 

 3:241. 1895. Not L. 



Perennial ; stem moderately stout, 4-6 cm. high, more or less 

 hirsute ; leaves all on stout petioles, those of the root leaves dilated 

 at the base, slightly clasping, those of the stem confluent with it 

 for a considerable distance, the blade 10-16 cm. long, 10-12 cm. 

 wide; leaflets in three or four subopposite pairs, exclusive of the 

 three-lobed terminal segment, more or less decurrent, ovate-lanceo- 

 late in outline, acute, usually two-lobed, and coarsely serrate, light 

 green when fresh, hirsute above with appressed hairs, clothed be- 

 neath with soft white short hairs ; inflorescence equalling or 

 slightly exceeding the subtending leaf; peduncles stout, grooved, 

 densely wooly, cymes compact : calyx half the length of the petals, 



very pubescent, parted almost to the base, the lobes linear-lanceo- 

 late, acute, heavily fringed with long white wavy hairs : corolla 

 cream-colored, or faintly tinged with purple, about I cm. long, 

 puberulent, especially on the lower half, the lobes broadly oblong, 

 obtuse, notched. 



The type is no. 3269, collected June 20, 1896, in the woods 

 at the head of Lake Waha, Nez Perces county, Idaho, altitude 

 2000 feet. Several dozen plants were growing in an open, grassy 

 place near a stream. The white appearance of the leaves is some- 

 what lost in dried specimens, but is conspicuous in the living plant. 



No. 112 of Sandberg, MacDougal and Heller, wrongly re- 

 ferred to H. Virginianutn, by Mr. Holzinger, belongs to this 

 species. These specimens were collected by the writer at two 

 stations, in the Clearwater valley, once on the banks of Peter 

 creek, under a clump of willows, and again in similar situations 

 along the 1 apwai. 



To this species are also referred two specimens from the State 

 of Washington. One was collected at Pullman, May 31, 1893, 

 no. 1697, by Prof. C. V. Piper, and labeled " Hydrophyllum 

 Occident ale" The other was collected by Sandberg and Leiberg 

 at Stevens Pass, August, 1.X93. labeled "Hydrophyllum I'irginia- 

 num" The leaflets in these specimens from Washington are 

 longer and sharper than are those of the type specimen.
