iculatis, ratnis oppositis nudis patentibus vel arcuato-ascendentibus 

 multicapitulatis, bracteis lanceolatis utrinque acutis integerrimis gra- 

 ciliter petiolatis supra glabris subtus aracbuoideo-tomentosis, petiolo 

 planiusculo glanduloso-bispidulo ; pedicellis filiformibus 1-5 mm. 

 longis ; capitulis discoideis 6-floris ; involucri squamis 13 acutis cili- 

 olatis exterioribus ovato-lanceolatis 1 mm. longis interioribus gradatim 

 longioribus angustioribusque intimis linearibus vel liueari-lanceolatis 

 5 mm. longis ; flosculorum omnium corollis 6.5 mm. longis gracilibus 

 sursum gradatim ampliatis sine faucibus distinctis, dentibus limbi line- 

 aribus ad apicem obtusiusculum attenuatis ; pappi setis biseriatis 

 exterioribus brevibus paucis planiusculis interioribus ca. 40 capillari- 

 bus fulvescentibus sursum scabriusculis. Achaenia immatura. — Near 

 Acapulco, Guerrero, Mexico, between October, 1894, and March, 1895, 

 Dr. E. Palmer, no. 245 (type, in hb. Gray). Tbis species belongs to 

 § Andromachia, 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 cm. 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 9 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. longis 

 interioribus ca. 50 capillaribus sursum minute scabratis ca. 6 mm. 

 longis albidis. — ■ Gualan, Department of Zacapa, Guatemala, C. C. 

 Beam, 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 much 

 shorter involucre, the latter scarcely exceeding the acheues.
