310 PHANEROGAMOUS PLANTS. 



before the leaves are unfolded. According to Dr. Kellogg (1. c.) the 

 tender inner portion of the scapes has somewhat the flavor of apples, 

 and is eagerly sought after and eaten by the Indians. 



Plate 5. — Saxifraga peltata. Plant with flowers, young leaves, 

 and portion of fruiting cyme. Fig. 1. A flower. 2. The same dis- 

 played. 3. Vertical section. 4. Portion of fruit. The details en- 

 larged. 



2. PARNASSIA, Iburn. 



1. Parnassia parviflora, Hook. 



Hab. Moist places along the Klamath River. — Radical leaves 

 ovate, the base attenuated into a long petiole. Scapes 12-16 inches 

 high, very slender, furnished above the middle with a small bract-like 

 leaf. Phalanges of sterile filaments consisting of 12 to 15 slender 

 bristles. Petals on slight claws. Hardly a distinct species from P. 

 palustris. 



3. HEUCHERA, Linn. 



1. Heuchera ctlindrica, Dougl. in Hook. 



Hab. Upper Columbia, Washington Territory, and Birch Bay, 

 Puget Sound. Also Cascade Mountains, Oregon; a smaller and 

 smoother form. — I find no petals, even rudimentary ones, in any of 

 the specimens. The smaller form, from the mountains, approaches 

 so near to H. glabella and H. ovalifolia of Nuttall, that all should be 

 reduced to one species. 



2. Heuchera micrantha, Dougl. 



Hab. Nisqually, Puget Sound. — The specimens are immature, but 

 they agree very well with H. micrantha.
