pinnately parted leaves in which the number of lobes varies from 

 one to five (Mrs. Wilder, no. 244, in part; Parish, no. 3604; Hall. 

 no. 1456). In type specimens the leaves are generally larger 

 than in any others I have seen, but one of these (on Univ. Calif, 

 sheet no. 35995) has no leaf more than 15 mm. wide. The num- 

 ber and height of the stems are of course variable characters. 



A low form not yet segregated is represented by my no. 1456 

 from Lytle Creek Canon, San Antonio Mts., 1830 m. alt., in the 

 Lower Transition Zone. These specimens are only 1 to 1.5 dm. 

 high : leaves mostly basal on the summit of a thick caudex, rather 

 small, dentate to pinnatifid: cyme 1 to 3-headed, the involucre 

 sometimes 1 cm. high. Two other forms, both of which have 

 received specific names, may be characterized as follows : 



Var. Bernardinus (Greene) Hall, comb. nov. 8. Bernardinus 

 Greene, Pitt. iii. 298 (1898). More slender than typical 8. 

 ionophyllus, 1.5 to 3 dm. high : tomentum rather persistent : 

 leaves crowded at the base ; the blade orbicular or cuneate-obovate. 

 .5 to 1 cm. wide, merely dentate or rarely a pair of small lobes 

 on the petiole : heads mostly 3 to 10 in each terminal cyme. Dry 

 hillsides in the Transition Zone at Bear Valley, San Bernardino 

 Mts., 2100 m. alt., Parish, nos. 1450, 3718, and Hall, no. 7557. 



Var. sparsilobatus (Parish) Hall, comb. nov. 8. sparsilobatus 

 Parish, Bot. Gaz. xxxviii. 462 (1904). Very slender, 1 to 2 dm. 

 high : herbage tomentose in the types but green and nearly devoid 

 of tomentum in some specimens collected under the same number : 

 leaves usually crowded in a basal tuft, sometimes clothing the 

 stem to the middle ; blade 1 to 2 cm. broad, occasionally roundish 

 and merely dentate, more commonly pinnatifid and the 3 to 5 

 broad lobes entire or coarsely toothed: heads mostly 2 to 4 in 

 each terminal cyme, or not rarely solitary. Transition Zone of 

 the San Bernardino Mts. from the upper Santa Ana River to Mt. 

 San Gorgonio ; not common in any one place but well distributed 

 usually in open forests of White Fir: Barton Flats and South 

 Fork, 2125 to 2600 m. alt., Mrs. Charlotte M. Wilder, no. 244 

 (type, in Herb. Parish) ; Upper Santa Ana Canon (Coon Creek, 

 etc.) to Dry Lake, 2300 to 2700 m. alt., Hall, nos. 7511, 7575, 

 7626.
