terminal ones. The characters of this plant are near some of 
those of the description of P. croceum. Collected in Barranca de 
Tlaquilosto, Puebla. No. 2527. 
Melampodium paryulum. Annuum caule erecto parce ra- 
moso superne oligophyllo, pubescenti: foliis ovatis obtusis, in 
petiolum alatum cuneatis, basi connatis et auriculatis, 3-4 cm. 
longis, 1.5—2 cm. latis, tenuis leviter pubescentibus penniveniis: 
capitulis paucis, pedunculis axillaribus 3-6 mm. longis; invo- 
lucri bracteis exterioribus 5 ovato-acuminatis basi connatis 4 mm. 
longis; ligulis 3-4, flavis 1 mm. longis auriculiformibus extus 
pubescentibus: squamis interioribus achzenia involventibus apice 
conico-acuminatis, margine irregulariter alatis vel tuberculatis: 
achzeniis levibus basi hamatis. 
The wings, tubercles and awns of the mature fruit are variable. 
The inflorescence of the dried specimens is hidden by the com- 
paratively large leaves, which resemble those of MZ. perfoliatum. 
Collected on Cerro Santa Lucia, Puebla, growing in shaded soil. 
No. 2813. 
Barroetea glutinosa. Annua parum ramosa undique dense 
glandulosa 1-2 dm. alta: foliis (cum petiolo 5-10 mm. longo) 2-3 
cm. longis, alternis late ovatis acuminatis dentatis basi cordatis 
vel cuneatis, 1-1.2 cm. latis: capitulis 1 cm. altis; pedunculis 
1-4 cm. longis: involucri bracteis lineari-oblongis striatis purpu- 
rascentibus 6 mm. longis exterioribus brevioribus: styli ramis 
superne ovato-dilatatis: achzeniis compressis, uno latere 1I- 
altero 1-2-nervato: pappi setis acheniis brevioribus. 
This is a very distinct species, differing from the others of the 
genus in having alternate leaves and being glandular. The 
basal callus of the akene is not large, and the style branches of 
the young flowers are conspicuously enlarged so as to appear 
ovate. The corollas are campanulate rather than tubular. Col- 
lected on Cerros, near San Luis Tultitlanpa, Puebla. No. 2625.
