cuspidate, narrowed to the sessile base ; the radical ones petioled, 

 rather thin ; the middle cauline 8 to 16 cm. long by .5 to 1 cm. 

 broad, either all entire or the lower obscurely serrate: panicle 

 dense, oblong, or sometimes more compound and pyramidal, the 

 heads not secund : involucre 3 or 4 jnm. high, its bracts scabrous- 

 ciliolate or entire: rays scarcely surpassing the disk: achenes 

 minutely to canescently pubescent. 



In moist places from Lower California to Los Angeles : Jamul 

 Valley, San Diego Co., Palmer, no. 136 ; San Bernardino Mts. at 

 2200 m. alt., Geo. E. Hall, no. 4; San Bernardino Valley at 300 

 to 450 m. alt., Parish, nos. 4197, 5887; Oak Knoll, near Los 

 Angeles, Braunton, no. 658 ; etc. The altitudinal range covered 

 by this species without undergoing a change in its characters is 

 remarkable, even for a Solidago. The common form of the San 

 Bernardino Valley, in the Upper Sonoran Zone, is exactly repro- 

 duced at many places in the neighboring mountains, even to 2300 

 m. altitude at the upper edge of the Transition Zone. 



f. luxurians Hall, form. nov. More robust and the herbage 

 succulent : leaves thickish, broadly lanceolate or oblong, the mid- 

 dle cauline often 15 cm. long by 2 or 2.5 broad: inflorescence 

 oblong or pyramidal, 1 to 3 dm. long : heads larger, the involucre 

 about 4 mm. high. Swampy ground, often in alkaline soil in the 

 vicinity of hot springs, and therefore an ecologic form : Arrow- 

 head Hot Springs, near San Bernardino, altitude 600 m.. Parish, 

 no. 1101 ; same locality, Nov. 1, 1890, Parish; same locality, Sept.. 

 1903, Dr. R. J. Smith; vicinity of San Bernardino, altitude 300 

 to 450 m., Parish, no. 3809; Ventura, Mar., 1861, Brewer, no. 

 247. Both this and the typical form were probably considered 

 by Dr. Gray while drawing up his original description of S. con- 

 finis; they certainly were considered while preparing the Synop- 

 tical Flora, since not only does the description include them both, 

 but mention is made of Parish's material from the hot springs, 

 as well as of Palmer's San Diego Co. collection. Dr. Robinson 

 informs me that it was G. R. Vasey's specimen from San Diego 

 Co. that Dr. Gray himself marked S. confin's, n. sp. I have not 

 seen Vasey's plant.
