ascending, 2-3 dm. tall, simple below, sparingly forked above, 
roughish; leaves linear-filiform, I-3 cm. long, acute, grooved on 
either side of the midrib, serrulate-ciliate, especially near 
the apex, sessile; stipules linear-lanceolate, 1-1.5 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. dichotoma, 
differing in the more robust habit, the minutely pubescent foliage 
and the strict few-flowered cymes. Faronychia scoparia has a 
larger calyx than P. dichotoma, the cusps are longer and more 
densely spiny-ciliate, and the calyx-segments are more strongly 
ribbed on the back. 
V PARONYCHIA CHORIZANTHOIDES. 
Annual, slender, minutely pubescent. Stem erect, 1-2 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. 1169, according to written 
label. Heretofore specimens of thiscollection 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 Chorizanthe, chiefly on 
account of the involucre-like calices. In Paronychia chorizanthoides 
the bracts subtending the calyx are shorter than that organ, while
