say whether or not it really belongs to S, lasiolepis at all. Ball in his 

 MS. -list does not mention this form. Bebb apud Watson^ Bot. Calif, ii. 

 86 (1879), proposed S. lasiolepis var. Bigclovii, and Ball, in his list, 

 keeps this variety quoting as synonyms: S. franciscana Von Seemen in 

 Bull. Torr. Bot. CI. xxx. 634 (1903); S. Sandhergii Rydberg, 1. c. 

 304 (1912); Fl. Rocky Mts. 192 (1917), and S. hoiscana Nelson in Bot. 

 Gaz. Liv. 406 (1912). The type of >S. franciscana came from the Cliff 

 House near San Francisco while the types of the other two species had 

 been collected in Idaho, Valley of Hatwai Creek, April 28, 1892, Sandberg, 

 Mac Dougal and Heller (no. 71, f.; N. Y.), and near Boise, May 29, 1911, 

 Miss June Clarke (no. 48, fr.). This variety also occurs in Nevada 

 (Ormsby County) and in Oregon but I am not well enough acquainted 

 with it to say more about its geographical distribution. 



Bebb, in 1879, also proposed a var.(?) Jallax of S. lasiolepis without 

 however mentioning a type. Judging by what I liave seen in Bebb's 

 hejrbarium Torrey's no. 491 (from 1865) seems to represent the type of 

 th s obscure form which is not quoted in Balls's list. 



In 1903, Von Seemen in Bull. Torr. Bot. Club xxx. 635, described a 

 second species S. Baheri, collected by C. F. Baker, on March 9 and May 

 10, 1902, on the foothills near Stanford University, Santa Clara County, 

 California (No. 274, f., m.; type m Herb. BeroL). This species is kept 

 by Ball as S, lasiolepis var. Baheri Ball, in litt. The ovaries of the type 

 are somewhat tomentose toward the apex. The geographical distribution 

 of this form is unknown to me. Jepson Fl. Calif. 241 (1909), does refer 

 a Bakeri as a synony ai to var, Bigelovii. Britton & Shafer, N. Am. Trees, 

 204, fig. 107 (1900), keep S. Bakeri ii distinct species with capsules "hairy 

 toward the top." 



56. S. ligulifolia Ball, in litt. — ? 5. cordata Ball apud Coulter & 

 Nelson, New Man. Rocky Mts. Fl. 132 (1909), pro parte, — Tliis species 

 proposed by Ball and known to me only in a few specimens which I saw 

 with Ball's own determination in Bebb's Herbarium (C.) seems to me most 

 closely related to S. lufea which however has longer pedicels. Both 

 species may be widely distributed from New ^Mexico and California to 

 Colorado, Wyoming and farther north. Partly on Ball's authority I 

 quote the following specimens as belonging to his species of whicli he, 

 unfortunately, lias not yet published a description. The specimens of 

 which the numbers are marked with an * liave not been determined bv

Ball. The leaves are mostly provided with stomata in the epidermis of 

 the uj^per surface, a fact also observed by me in S. lutca and, partly, in 

 S. mackenzieajtay but not in typical S. cordata.
