BUPATOEIACEvB. 11 



ferruginous retrorse hairiness : leaves firm, ovate-elliptic, 2 or 3 

 inches long, lightly serrate, acuminate, short-petioled : bracts 

 of involucre striate, lightly pubescent, commonly fleshy-tinted : 

 corolla with slender tube and short funnelform limb : ovaries 

 pubescent. 



Pringle's 8028, distributed under the name E. ciliatum, though 

 not like that in either aspect or character. 



K. ACUTA. E. ageratifoHum var. acuminatum, Coult. Contr. 

 XT. S. Herb. 179. Suffrutescent, rigid, brittle, the branches and 

 lower face of leaves pubescent: leaves deltoid-ovate, coarsely 

 subserrate-toothed on the sides, the subtruncate base and short 

 acumination entire ; petioles slender, shorter than the blades : 

 heads rather few and large in a broad sessile cyme : involucres 

 somewhat imbricate, the rather more than biserial bracts linear, 

 acute, 2-nerved: corolla tubular-funnelform, short achenes 

 setulose both along the raised and whitened angles and in a 

 less degree between them : pappus firm, yellowish. 



This is in many ways very unlike K. ageratifolia, and so much 

 so as to its involucre that I have hesitated before admitting it 

 into Kyrstenia. 



K. LjETA. Rigidlyshrubby, divaricately branched, the flower- 

 ing branchlets densely leafy, the foliage, pedicels and involucres 

 of a bright green ; strongly resinous-viscid : leaves deltoid-ovate, 

 acute, obscurely crenate-dentate, closely reticulate-renulose : 

 heads short and smallish, in sessile crowded compound cymes : 

 bracts of involucre biserial, subequal, oblong-lanceolate, 2-nerved 

 below : achenes minutely setulose along the thin sharp angles. 



Foot of Monte Alban, Oaxaca, Mexico, 23 Oct. 1894, C. L. 

 Smith; distributed for E. calamitithcBfolium, io yihich it bears 

 no near relation. 



K. CALOPHTLLA. Shrubby ; branches suberect, ending in a 

 short-peduncled cyme : leaves i to f inch long, suborbicular to 

 subdeltoid-ovate, somewhat crenate-toothed, glabrous, coriaceous, 

 remarkably scrobiculate beneath, the reticulations circumscrib- 

 ing shallow depressions: bracts of involucre scarcely biserial, 

 oblong, acutish, purple-tipped : slender corollas pinkish ; achenes 

 pubescent. 



Near Saltillo, Mexico, June, 1898, Palmer (n. 318 in U.S. 

 Herb.); the specimens labelled F. calaminlhxfolium.
