13 Muhlenbergia, Volume 7 



a species of western Colorado which may be 5". giiercifolia Greene. 

 Dr. Greene has also described two other species from Colorado, 

 6". siibpi7inata from the canyon of the Arkansas at Canon City, 

 and 5'. oxyacaiithoides from Grand Junction. These two I have 

 not seen. However, tliere are several species of ScJi7naltzia in 

 Colorado, and not one, as some botanists have supposed. 



/ Carcluus vernalis sp. nov. 



Perennial from a deep root, 2 to 4 dm. or more hiorh, strict 

 and having one or two heads on the smaller plants, or branched 

 and having numerous heads on the large: stems with some to- 

 mentum at /the time of flowering: leaves all narrowly linear, 

 white tomentose beneath, green with slight tomentum above, 

 the lower about i dm. long, scarcely i cm. wide, rather distantly 

 toothed, the narrow triangular teeth pointed by weak spines, 

 the upper leaves successively smaller and continuing to the 

 heads, sessile by a clasping base, scarcely at all decurrent on the 

 stems: heads 1.5 to 2 cm. wide and the same in height to the 

 end of the bracts; these in about 8 series in successive lengths, 

 6 of the series short and fimbriate tipped, the 2 upper series 

 lengthened and ending in scarious, usually twisted tips: flowers 

 bright red-purple: seeds dark brown, small, 5 mm. long, 2 mm. 

 wide. 



The type specimens were collected at De Beque, Mesa 

 county, Colorado, May 26, 1910, no 422^. Professor Elsworth 

 Bethel also collected it at the same place in 1909. It is quite 

 common on the hills north of De Beque, and I think extends 

 northward to Routt countv. 



The color of the flowers and the fimbriate tips of the bracts 

 would place this species with C. perplexans Rydb., but the 

 leaves are much narrower and there are more series of bracts. 

 While this species and C. perplexatis have fimbriate tipped 

 bracts, suggesting relationship with C. americanus (Gray) Greene 

 I do not regard them as closely related to it. They are both 

 from the western slope and do not grow at high elevations. C. 

 amej'icanus seems to belong to timbered sections, and these to 

 the_open_country. 



New Windsor, Coloradu.
