VI.— NEW SPECIES OF PACIFIC COAST PLANTS. 



I. Campanula angustiflora, sp. nov. 



Plate XI, Figs. 2a-2C. 



Annual, scabrous-hispid; stems slender, angled, 1-3 dm. high, branching 

 diffusely from the base to the top with upwardly spreading branches: leaves 

 sessile, ovate to orbicular, acuminate or acute, deeply dentate, 5-15 mm. 

 long, 3-10 mm. wide: flowers axillary on stout, upwardly spreading pedun- 

 cles, twice to four times the length of the flower; divisions of the calyx linear- 

 subulate, almost equalling the corolla, connivent in fruit; corolla tubular, 

 with five triangular lobes; stamens included, the anthers linear, longer than 

 the thin, broadly triangular-subulate filaments; ovary obovoid, slightly con- 

 stricted at the apex, ribbed; style short, thick, with three revolute stigma 

 lobes; fruit strongly ribbed, irregularly humped with the three valves above 

 the middle; seeds numerous, minute, shining, light brown, with a small 

 darker spot at one end, 3-sided or keeled. 



This has been included under C. exigiia Rattan by Mrs. 

 Brandegee, who first discovered it on Mt. Tamalpais, July 

 5, 1886, collecting it again in the same locality June, 1890, 

 and July, 1893. She also found it on Mt. St, Helena, May 

 to July, 1889.^ It was rediscovered on Mt. Tamalpais by 

 Mr. J. W. Congdon, and by the writer near the water tank 

 at the head of the East Fork of Sequoia Canon on the rail- 

 road track. 



Besides the points of difference shown by the figures of 

 the two species, there are differences in habit of growth 

 and general appearance. C . exigua is lower, more slender, 

 less branched, and with the branches divaricately spreading; 

 the leaves are smaller and narrower, and almost hug the 

 stem. The figures are drawn from a specimen collected 

 by Volney Rattan on Mt. Diablo, Calif. It is probably 

 part of the type. In the Herbarium of the Academy there 

 are specimens from Mt. Hamilton, Calif., collected by W. 

 W. Price, similar to those of the Mt. Diablo Campanula. 



From Priest Valley in Monterey County, Calif., very 

 young specimens of an annual Campanula were collected 

 by the writer. May 12, 1893, resembling C. angustiflora in
