in a rather small open cymose panicle : involucral bracts ovate^ 

 acute or cuspidate, ciliate on the margins, sparingly so on the 

 back : corolla-lobes of sterile flowers vvith scanty pubescence 

 if any : achcnes obovate, conspicuously pilose at apex. — 

 Guatemala, Depart. Guatemala, alt. 5000 feet, Feb., 1890 

 (y. D, S. 2347). This spccies is near C. Siirinanicnse L. , var. 

 asperuni Baker, but it differs in jts comparatively smooth 

 corolla-lobes of the sterile flowers, and strikingly in its large 

 broad leaves, velvety pubescent beneath, and long petioles. 

 From C. ai^boreitm DonncII Smith it differs in its involucral 

 bracts, leaves, and villous achenes. 



MONTANOA OVALIFOLIA DC. is worthy of mention as being 

 a plant reported before only from Bogota. These specimens 

 are from Pacaya, Depart. Amatitlan, alt. 6000 feet, March, 



1890 (y. D. S. 2352). 



Tetragonotheca Guatemalensis n. sp. — Apparently closely 



allied to T, Texana Gray and Engelm. ; but the leaves are del- 

 toid, with mucronate serrulations and usually one or two 

 prominent basal teeth, abruptly decurrent into a winged 

 petiole which docs not enlarge or clasp at base ; leaves of the 

 inflorescence ovate-lanceolate to lanceolate, acuminate, taper- 

 ing gradually to a petiole : corolla-tubes, both of the ray and 

 disk-flowcrs, very long and slender, more or less glandular 

 pubescent, as is the whole inflorescence : pappus none in our 

 specimens. — Senahu, Depart. Alta Verapaz, alt. 3500 feet, 

 April. 1889 (y. D. 5. 1592). A remarkable Tetragonothcca on 

 account of its long and slendcr corolla tubes, the showy yellow 

 ligules looking conspicuously slender-clawed. 



Zexmenia Dulcis n. sp. — Pubescent and branching: leaves 

 thickish, opposite, short-petioled, ovate or oblong, acute, 

 distantly mucronate-serrate, scabrous on both sides but very 

 much more so above, 6 to 9 cm. long, 3.5 to 5 cm. broad : 

 heads on rather long peduncles (2.5 to 5 cm.), about 10 mm. 

 high : involucral bracts lanceolate to ovate, mostly acute, 

 scabrous with rough hairs : bracts of the receptacle winged on 

 the back, with a sharply acute or acuminate minutely toothed 

 apex : achenes of the ray 3-angIed and 3-awned; those of the 

 disk broadly winged, with usually two prominent unequal 

 awns and numerous small squamellie. — Rio Dulce, Dcpart. 

 Livingston, alt. feet, March, 1S89 (J. D. S. 1607). Rcsem- 

 bling Z, scandens Hemsl. somcwhat, but differs from that 

 species in its acute leaves, long-peduncled and smaller heads,
