340 BOTANICAL GAZETTE [april 



closer study of many difficult forms which I can only briefly mention 



will lead to a different conception of them. 



I have seen specimens of var. Bolanderiana from the following counties in 

 CaUfornia (north to south): Humboldt, Siskiyou (.4. A. Heller, no. 8058, 

 female part not quite typical), Shasta, Lassen, Plumas, Butte, Nevada, ?Men- 

 docino (.4. Kellogg and W. G. W. Hartford, no. 922, ?Ukiah), Lake, Solano, 

 Alameda (Sunol), Amador, Tuolumne, Mariposa (Bolander, no. 4958, type!, 

 Yosemite Park, Slough's Valley), Fresno, Monterey, Tulare, and Kern. It 

 may even occur farther south. 



There is a specimen from San Bernardino County, near head of 

 San Antonio Canyon, in a narrow rocky canyon, alt. 2250 m., 

 July 5, 1918, /. M. Johnston (no. 2087, flor. abnorm. m. et f. 

 mixtis; A.; "shrub, low, under im."). The leaves are almost 

 wholly glabrous when maturing, at least on the lower surface, which 

 is more or less distinctly glaucescent. The flowers, however, are 

 abnormal, the female ones hard to distinguish from those of S. 

 exigua, but glabrous, or almost so. The form may belong to S. 

 exigua virens, if there is really such a variety, or it may be 

 related to var. Bolanderiana. The normal form is represented by 

 Johnston's nos. 1401 and 1665, from the upper San Antonio Canyon. 

 I am much obliged to Mr. Johnston for the following information: 



Numbers 1401, 1665, 2087 from near head of San Antonio Canyon. To 

 me this is the most interesting plant I sent you. I have thoroughly explored 

 the San Antonio Mountains, but I have only found the single colony from which 

 all my specimens were obtained. It grows as a dense, low, compact shrub 

 (hardly over a meter in height) on the rocky floor of a very deep gulch. A short 

 distance away is found a large colony of S. flavescens and scattering shrubs of 

 S. Watsoni. The nearest Longifoliae that I know of is 7 miles away and is the 

 colony from which my 1685, which you doubtfully referred to S. Parishiana, 

 was obtained. I have never yet seen in S. California a Longifoliae so high 

 in the mountains and associating with such typically boreal species as this one 

 does. You have probably noted that the aments contain both staminate and 

 pistillate flowers, which may be due to its strange habitat. I noted that a large 

 percentage of the aments were entirely sterile at the tune I collected the 

 specimens. 



8. S. LONGiFOLiA Muhl. in Neue Schr. Ges. Natf. Fr. Berlin 

 4:238. pi. 6. fig. 6. 1803, non Lamarck;" in Ann. Bot. Konig 



" According to the international rules, Muhlenberg's name can stand because 

 Lamarck's (Fl. Fr. 2:232. 1778) is nothing but a synonjon of S. viminalis L.; in 

 following the Philadelphia Code the name S. interior Rowl. has to be used, and I would 

 not keep Muhlenberg's name if Lamarck's were not an unconditional synonym, and 

 could be applied to a form differing from typical S. viminalis.
