ascending, 2-3 dm. tall, simple below, sparingly forked above, 

 roughish ; leaves linear-filiform, 1-3 cm. long, acute, grooved on 

 either side of the midrib, serrulate-ciliate, especially near 

 the apex, sessile; stipules linear-lanceolate, I-1.5 cm. long, 

 attenuate ; branches of the cymes erect or strongly ascending ; 

 sepals linear-lanceolate, gradually narrowed to the apex, 3-3.5 

 mm. long, firm, keeled, usually with a short lateral nerve on each 

 side of the keel, hooded, prolonged into a stout ascending cusp, 

 which is one-third to one-fourth as long as the body ; petals none ; 

 stamens half as long as the sepals ; anthers yellowish. 



The specimens on which the above species is founded were 

 collected by Dr. Edward Palmer, in the Indian Territory, between 

 Fort Cobb and Fort Arbuckle, in 1868. (No. 27.) 



As far as I know. Paronychia scoparia has not been referred to 

 any previously described species. It is related to P. dicJiotoma, 

 differing in the more robust habit, the minutely pubescent foliage 

 and the strict few-flowered cymes. Paronychia scoparia has a 

 larger calyx than P. dicJiotonia, the cusps are longer and more 

 densely spiny-ciliate, and the calyx-segments are more strongly 

 ribbed on the back. 



Paronychia chorizanthoides. 



Annual, slender, minutely pubescent. Stem erect, I-2 dm. 

 tall, forking from a point 3-8 cm. above the base; leaves linear- 

 filiform, .8-2 cm. long, acute, with a stout midrib, sessile ; stipules 

 lanceolate, silvery, acuminate; calyx short-pedicelled, or nearly 

 sessile, 1.5 mm. long, strigose at the base, finally urn-shaped, the 

 base much enlarged ; sepals ovate or ovate-lanceolate, with a stout 

 midrib, abruptly contracted into the ascending cusps which are 

 about one-half as long as the body at maturity; utricle nearly i 

 mm. broad. 



The specimens on which the species here described as new is 

 founded were collected by Dr. Edward Palmer at Bluffton, Burnet 

 County, Texas, 50 miles west of Georgetown, October 10-15, 1879, 

 according to printed ticket, or 1883, no. 1 169, according to written 

 label. Heretofore specimens of this collection have been referred to 

 Paronychia setacea, which species, however, they but slightly re- 

 semble. Paronychia chorizanthoides, as the name suggests, bears a 

 remarkable resemblance to some species of ChorisaJithe , chiefly on 

 account of the involucre-like calices. In ParonycJiia chorisantJioides 

 the bracts subtending the calyx are shorter than that organ, while
