gine ciliato-puberulis, imo in petiolum linearem complanatum 

 cuneatis; capitulis majusculis; involucro multipartite, laciniis 

 oblongis, acutis, puberibus. — Chile, Prov. Concepcion, v. s. in 

 herb. Mus. Paris. (CL, Gay). 



Caules plures, fere 2-pedales, erecti, obsolete striatic virgati ; 

 folia radicalia 2\ poll., caulina 1J-2J poll, long., cum laciniis 

 4-6 lin. lat. ; capitula in flore 7-8 lin. diam., demum in fructu 

 14 lin. diam. ; involucrum multipartitum, laciniis lanceolatis, 

 integris, patentibus, insequalibus ; flores involucro excedentes; 

 calycis dentes 5, parvi, subrotundi ; corollse tubus imo tenuissi- 

 mus, viridis, superne infundibuliformis, 5-fidus, albus ; palese 

 inter flores plurimse, spathulatse, foliacese, involucro sequilongse, 

 margine ciliatse. 



3. Calycera squarrosa, n. sp.; — glaberrima; foliis radicalibus 

 plurimis congestis, oblongis, irregulariter pinnatifido-incisis, 

 summo segmentisque obtusiusculis, iterum sinuato-dentatis 

 dentibus spinescenti-mucronatis, crassis, margine cartilagineo, 

 in petiolum longissimum angustum alatum decurrentibus ; 

 pedunculo scapiformi, monocephalo, nudo, folio breviore ; 

 capitulo majusculo; involucro ad basin 5-partito, laciniis 

 linearibus, patentibus, aceroso-denticulatis ; paleis spathulatis, 

 acerosis, crassis, viridibus, flores excedentibus. 



Species duabus prseviis affinis, sed planta multo humilior : folia 

 (petiolo incluso) 3 poll, long., lamina pollicaris, 7 lin. lat. ; seg- 

 menta 2-3 inferiora remota et squarrosa; petiolus alatus, 1J-2 

 poll, long., 1 lin. lat.; pedunculus nudus, 1 poll, long., apice 

 crassior; capitulum 1 poll, diam.* 



4. Calycera sinuata, n. sp.; — glaberrima; foliis radicalibus plu- 

 rimis, congestis, ovato-oblongis, irregulariter sinuato-dentatis 

 dentibus brevibus, apice callosis, crassis, sub-3-nerviis, in 

 petiolum longum cuneatis; caulinis paucis, alternis, confor- 

 mibus, et multo brevioribus ; capitulo terminali ; involucri 

 foliolis 5, spathulato-oblongis, subintegris, crassis, patentibus. 

 — In Andibus Chilensibus, ora orientali (Puente del Inca, 

 altit. 8000 ped.), v. v. 



Planta anno 1825 mihi inventa, habitu prsecedentis, 3-polli- 

 caris ; radix fusiformis, 1| poll, long., folia radicalia 2 poll, long., 

 4 lin. lat., lamina in petiolum complanatum alatum linearem 

 subsequilongum decurrens ; caulina similia, 9 lin. long., 2 lin. 

 lat. ; capitulum in fructu globosum, 9 lin. diam., spinis inclusis 

 1 J poll. diam. ; foliola involucri 4 lin. long., 1 J lin. lat. ; achsenii 

 spinse rigidae, patentes, subulatae, superne subsulcatse j\
