ones equal, very obtuse, more or less scarious margined: 
achenes sharply 5-angled, somewhat hairy, especially on the 
angles.—PLATE V. 
Jumaytepeque, Depart. Santa Rosa, alt. 6,000", December 
1892, Heyde & Lux 4,255. ; 
To decide the affinities of this genus is very perplexing, 
The style characters are those of EUPATORIACEA, and its pappus 
coalesced at base into a prominent ring suggests the Brazilian 
genus Symphyopappus Turcz., but the distinctly sagittate 
anthers are opposed to such reference. It seems also to ré- 
semble certain groups of SENECIONIDA, and this may be the 
true reference, but the involucre is hardly consistent with tt. 
It is tentatively referred here to INULOIDE&, to which group it 
is as easily referred as Dimeresta Gray, with which genus it 
has a number of important characters in common. 
NOCCA SUAVEOLENS Cass. (Lagascea suaveolens HBK.).— 
Carrizal, Depart. Santa Rosa, alt. 5,000%, November 1892, 
Heyde & Lux 4,227. A somewhat variable species, which - 
also includes L. helianthifolia HBK., L. latifolia DC., and 
L. macrophylla Steud. Lagascea Cav. is 1,803, and Mocca 
Cav. is 1,794. 
DESMANTHODIUM GUATEMALENSE Hemsley.—Volcan Ac- 
atenango, Depart. Zacatepequez, alt. 12,000", August 1892, 
W. C. Shannon 3,693. The only record I find of this very 
interesting plant is the original collection by Salvin on Vol- 
can de Fuego, at 6,000%, in which material the achenes were 
immature. The specimens before me have perfect achenes, 
which show the oboval-oblong outline of the other species, 
are perfectly smooth, and become black and hard, but instead 
of being biconvex in section have a flat face and a promin- 
ently angled face, giving a low triangular section. 
Polymnia Quichensis, n. sp.—Smooth, excepting the more 
site, ovate-lanceolate, acuminate, tapering at base to a short 
petiole, dentate or denticulate (sometimes almost entire), 
moderately scabrous above and somewhat pubescent beneath, 
especially upon the conspicuous reticulations (becoming 
smoother with age), 12.5 to 25™ long, § to 7.5™ wide: heads 
solitary or few in a terminal corymb whose lateral branches 
bear at least a pair of ovate (sometimes narrower) acuté 
leaves; the disk about 15"" broad: outer involucral bracts 
broadly ovate and acute: rays 7 to 15, yellow, linear-oblong,
