Acapulco, Guerrero, Mexico, between October, 1894, and March, 1895, 
Dr. ype, in hb. Gray). This species belongs to 
: t 
ndromachia, and is closely related to L. glabrum Hemsl., but it 
differs in its much looser corymbose-paniculate inflorescence, its shorter 
involucre, and much more attenuate involucral scales. 
Liabum Deamii Robinson & Bartlett, n. sp., scandens 3-5 m. 
longum ; caulibus anthesi delapsu foliorum ignotorum nudis subtereti- 
bus lanulosis albidis, internodiis 2-4 em. longis, nodis crassiusculis ; 
inflorescentiis ovoideis thyrsoideis multicapitulatis albido-lanuginosis 
1-1.5 dm. longis 5-8 cm. diametro; bracteis petiolatis ovatis integris 
discoloribus supra leviter griseo-pubescentibus subtus albo-lanatis; 
ramulis 3-5-capituliferis; capitulis discoideis 6-floris subsessilibus 
vel brevissime pedicellatis ; involucri squamis ca. 13 obtusis exterio- 
ribus ovatis ca. 2 mm. longis externe pubescentibus interioribus 
gradatim majoribus 3-4 mm. longis ovato-oblongis apicem versus 
pubescentibus ; flosculis @ involucro longe exsertis, corollis glabris 
verisimiliter flavidulis 7 mm.’ longis, faucibus cylindratis tubum pro- 
prium graciliorem subaequantibus, dentibus limbi patentibus anguste 
lanceolatis acutissimis ; achaeniis 2.5 mm. longis deorsum angustatis 
griseo-olivaceis modice compressis striatulis breviter pubescentibus ; 
pappi setis 2-seriatis exterioribus paucis subpaleaceis 1-2 mm. longs 
interioribus ca. 50 capillaribus sursum minute scabratis ca. 6 mm. 
longis albidis. — Gualan, Department of Zacapa, Guatemala, 0. @. 
Deam, no. 194 (type, in hb. Gray). This species clearly belongs to the 
§ Andromachia, and appears to be nearest L. glabrum Hemsl., from 
which it may be distinguished, however, by its pubescence and muc 
shorter involucre, the latter scarcely exceeding the achenes.
