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

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

 P. Chilensis, DC, has narrower and more pectinate teeth to a somewiiat incurved wing, 

 and the nutlet arcuate-recurved in age. 



P. penicillata, A. DC, I- 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. — Ci/no(jhssum penicillatum. Hook. & Arn. Bot. Beech. 371. — British 

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

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



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

 (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, 

 Greene. (Chili.)

broad leaves, the lower petioled. Flowers in panicled mostly bractless racemes 



(purple, blue, or white), in summer. 



* Biennial weed of the Old World : nutlets with somewhat depressed back surrounded by a slightly 

 raised margin, ascending on the pyramidal gynobase, and after separation hanging by the splitting 

 from the base of exterior portions of the long-subuiate indurated stjde. 



C. OFFICINALE, L. Common Houndstongue. About 2 feet high, soft-pubescent, some-
