152 Plantce Lindheimeriaruz. 



think that it is not specifically different from the plant which 

 was earlier indicated (from a branch, bearing narrowly linear 

 leaves alone) by Dr. Torrey, under the name of I. lineare ; 

 which name I have therefore adopted. The stipules should 

 not have been termed " minute " in I. lineare, since they are 

 further said to be " one-third the length of the leaves." The 

 upper ones are seldom so long as this, while the lower are 

 frequently " half as long as the leaves," as they are said to be 

 in I. stipulaccum. It is manifest that all our specimens belong 

 to one and the same species.

CARYOPHYLLACE^E. 



335. Paronychia Lindheimeri (Engelm. ined.) : annua, 

 glabra, erecta ; caule ramosissimo difTuso in cymas apertas 

 multoties dichotomas diviso ; foliis setaceis, superioribus brac- 

 teisque consimilibus mucronatis internodio brevioribus ; calyce 

 basi breviter pubescentibus, laciniis in aristulam iisdem duplo 

 breviorem productis. — Naked, rocky places in high prairies. 

 September. (Also gathered in Western Texas, by Mr. 

 Wright. — Nearly allied to P. setacea, and very similar in 

 aspect, foliage, flowers, &c, but the cymes are more open ; 

 the calyx minutely pubescent, instead of strigose-hirsute, at 

 the base ; and the awns much shorter than its segments, in- 

 stead of being nearly of their length. The plant is smoother, 

 often six inches high, and very much branched.
