228. Pectis angustifolta, caule basi ramoso, diffuso ; 

 foliis angusto-Iinearibus, mucronatis, basi denticulato-pilife- 

 ris ; floribus lermiualibus, soliiariis, brevissime pedunculatis; 

 invo!ticr<» octoph\llo; pappo brevissimo, quinquedentato. 



Desc. Root annual, fibrous. Stem branched, and spreading at the 

 base, 1-2 inches high; branches pentangular, smooth. Leaves opposite, 

 an inch or more in length, scarcely half a line broad, entire, mucronate at 

 the tip, revolute on the margin, furnished on each side of the midrib with 

 a row of yellowish pellucid glands, towards the base denticulate, the den- 

 tures terminating in conspicuous hairs. Flowers terminal, on very short 

 peduncles, which are enveloped in the leaves. Invulurrum 8-leaved, sub- 

 campanulate; leaflets distinct, equal, in a single series, coriaceous and 

 convex. Florets of the ray 7-8, yellow, limb entire, oblong: of the disk 

 tubular, yellow, 5-toothed, smooth. Anthers not aristate at the base. Style 

 pubescent and glandular; stigma indistinctly 2-lobed. Seed smooth. Pap' 

 pus chaffy, minute, 5-toothed ! Involucrum naked. 



Hab. On the Rocky Mountains. 



Obs. Allied to P. canescens of Kunth. In the character 

 of the pappus, this species recedes from Pectis ; but in habit, 

 it entirely agrees with that genus. 



229. Stkvia sphacelata, Null. mss. A plant with the 

 habit of Stevia, but with a many-leaved involucrum, enclosing 

 2f>-30 flowers. It appears to be more nearly allied to Polyp- 

 teris or Hymenopappus.

06s. Differs from the southern plant in its broader leaves 

 and larger flower. Florets of the disk conspicuously ciliate 

 with articulate hairs. 



231. G. pinnatifida, foliis pimiatifidis ; laciniis lineari- 

 lanceolatis, subintegris. 



Desc Stem about a span high, simple, or a little branched towards the 

 base, pubescent. Leaves alternate, canescently hirsute, pinnatifid ; the 

 divisions few, narrow, mostly entire, rather acute. Flower solitary, on a 

 long terminal peduncle smaller than in G. bicolor. Involucrum flat, many- 

 leaved ; leaflets in two series ; the exterior reflexed. Florets of the ray 

 deeply S-eleft, purple at the base, yellow towards the extremity : of the
