 the upper leaves entire; umbels 7 -10 cm. broad. In waste places, Vt., Conn, and 

 N. Y. [Ligusticum Levisticum L.] 



40. CYMOPTERUS Raf. (See Appendix.)

 and white flowers (in our species) in peduncled umbels. Involucels of 1 to numer- 

 ous bracts. Calyx-teeth rather prominent. Stylopodium depressed or wanting. 

 Carpels dorsally flattened, with 3-5 flat equal wings; oil-tubes several or soli- 

 tary in the intervals. [Greek, wave-winged, referring to the fruit.] About 13 

 species, natives of western and central N. Am. 



Involucre none. 1. C. acaulis. 



Involucre prominent. 2. C. monfatnts.

 capitate, 2.5 cm. broad or less; rays 2-5 mm. long; involucre none; involucel of a 

 single palmately-lobed bractlet; fruit broadly oval, about 6 mm. in diameter; 

 oil-tubes 4 or 5 in the intervals. In dry soil, Minn, and Wis. to Ark., the N. W. 

 Terr., Br. Col. and Colo. April-May. 



2. Cymopterus montanus T. & G. Mountain Cymopterus. (I. F. f.
