P. linearis, DC. Diffuse : nutlets with narrowly oblong body (one or two lines long),

 or cleft into subulate teeth, ending in a delicate uncinate-tipped bristle : cotyledons ob- 

 long. — Benth. Gen. 1. c. P. linearis & P. Chilensis, DC. Prodr. 1. u. P. Chilensis, C. Gay,

 Dry gravelly soil, southern part of California, Utah, and Arizona. (Chili.) One form, 

 answering to P. linearis, DC, has coarsely cleft nearly plane wings; another, answering to

 and the nutlet arcuate-recurved in age. 



P. penicillata, A. DC, 1. c. Very diffuse and slender : nutlets with oblong body (aline 

 long) surrounded by a merely undulate or pandurate wing (incurved in age), its rounded 

 apex thickly and the sides rarely or not at all beset with slender uncinate bristles : cotyle- 

 dons oblong-obovate. — Cynoglossum penicillatum, Hook. & Arn. Bot. Beech. :J71. — British 

 Columbia (Macoun) to California and W. Nevada. (The Missouri habitat and the syn. 

 of Nuttall, cited by A. DeCandolle, belong to Echinospermum Redowskii.) 

 P. lateriflora, DC, of Peru, has broadly obovate and less geminate nutlets, as noted by 



Bentham, with the wing dentate in the manner of P. linearis. 



§ 2. Gruvelia. Nutlets broadly obovate and equably divergent (a line long), 

 the wing or margin entire : cotyledons broadly obovate. — Gray, Proc. Am. Acad, 

 xii. 81. Gruvelia, A.DC Prodr. x. 119. 



P. setosa, Gray, 1. c. Hispid, as well as minutely strigose-pubescent, rather stout : 

 calyx-lobes armed with 3 or 4 very large divergent bristles : nutlets bordered by a broadish 

 (entire or obscurely undulate) thin-scarious wing; the faces as well as margins beset with 

 slender uncinate-tipped bristles. — S. E. California, on the Mohave desert, Palmer. 



P. pusilla, Gray, 1. c. Strigulose-canescent, slender : nutlets cuneate-obovate, wingless, 

 and with a carinate mid-nerve on the upper face, the acute margin beset with a row of 

 slender uncinate-tipped bristles. — Gruvelia pusilla, A.DC. Prodr. x. 119; C Gay, Fl. Chil. 

 1. c. fig. 3. — Common about Yreka, in the northern part of California, apparently native,
