Heller: new and interesting species from mexico. 35 



The type is our no. 3580, collected May 26, 1897, at Bar- 

 ranca, Taos county, altitude 6900 feet. It is very abundant in 

 open grassy, sandy soil, about Barranca station, growing in large 

 patches. This species is likely to occur in Colorado also, as it 

 occurs on the plateau which runs up into Colorado between the 

 two mountain ranges, and specimens of it will probably be found 

 in herbaria under the name of P. aciiminatis Dougl., which 

 northwestern species seems to be a convenient depositoiy for 

 anything which at all remotely resembles the original.

Specimens referable to this species were collected in Santa 

 Fe Canon, about twelve miles from Santa Fe. They were 

 growing in wet ground along the stream, at a place well within 

 the woods. Although numerous plants were seen, only a few 

 specimens were obtained, as it was just coming into bloom and 

 that part of the Canon was not again visited. To the best of 

 my knowledge, the species has not hitherto been recorded within 

 the borders of the United States. No. 3820.

In our distribution of New Mexican plants of 1897, this spe- 

 cies was erroneously determined as ^'■Sitilias mtilticazilis {Y)Q.) 

 Greene." It was collected in a meadow along the Rio Grande 

 river opposite the Indian Pueblo of San Juan, no. 3758. The 

 specimens were obtained either in damp ground, or sometimes 

 actually in water in swampy places. In some of the specimens 

 the leaves are entire, or the lower ones only slightly toothed, 

 while in others the lower ones are conspicuously pinnatifid. 

 The original came from " Fisch's Ranch, in southern Arizona, 

 at 5000 feet altitude." Rothrock, 699. 



The type-specimens are deposited in the herbarium of the 

 University of Minnesota.
