ZAUSCHNERIA ORBICULATA n. sp. 

 GEORGE L. MOXLEY 



Plant aliout 2 dm. or less in height, decumbent or ascending, sparsely 

 short white hairy, leafy; cauline leaves opposite, orbicular or rarely some- 

 what obovate. rather coarsely callous-denticulate, emarginate to abruptly 

 short-inucronate, the largest about 15 mm. in diameter; floral leaves 

 orbicular shell-like bracts 3 to 5 mm. in diameter; calyx tubular. 14 to 16 

 inin. long, its laciniae 5 mm. long, minutely puberulent, the tips slightly 

 divergent in bud ; petals aliout 8 mm. long, narrow, with a deep sinus ; 

 stamens barely exserted ; style exserted 5 to 8 mm. ; ovary 5 to 7 mm. 

 long, minutely glandular; capsule about 15 mm. long, fusiform, short- 

 pedicellate or subsessile, long loeaked. 



Saw Mill Canj'on, eastern slope of the Sierra Nevada, in loose lava 

 at 7500 ft. altitude, Aug. 28, 1919. Collected by Frank W. Peirson, no. 

 759. Type in author's herbarium. Duplicates in herb. Frank W. Peir- 

 son, Pasadena, Calif.; Dudley Herbarium. Stanford University; Cali- 

 fornia Academ)' of Sciences ; U. S. National Herbarium ; Gray Herbarium. 



This is a plant of very striking appearance and quite distinct from any 

 form I have yet seen. The orbicular, sometimes obcordate and somewhat 

 emarginate leaves serve to distinguish it at once from any other Zausch- 

 neria. It is of the tubular small-flowered type, resembling to some extent, 

 in its floral characters Z. glandulosa. Z. Hallii and Z. piilchcUa, and in the 

 foliar characters somewhat approaching Z. clcgans Eastw.
