EUPATORIACEZ. Wal 
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 Æ. ciliatum, though 
not like that in either aspect or character. 
K. acuta. Æ. ageratifolium var. acuminatum, Coult. Contr. 
U. 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 Æ. ageratifolia, and so much 
so as to its involucre that I have hesitated before admitting it 
into Kyrstenia. 
K. LÆTA. Rigidly shrubby, 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 Æ. calaminthefolium, to which it bears 
no near relation. 
K. CALOPHYLLA. Shrubby; branches suberect, ending in a 
short-peduncled cyme: leaves 3 to ? 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 E. calaminthafolium.
