Senecio Behmianus Muschler n. spec. — Frutex in partibus superioribus 



herbaceus; ramis ramulisque juventute pilis satis longis albidis simplicibus uni- 



cellularibus subtomentosis, dein mox glabratis, teretibus, evidenter sulcatis vel 



sulcato-striatis, viridibus vel denique peridermate ochraceo-rubro obtectis, plus 



minus dense foliosis. Folia alterna (internodiis in speciminibus usque ad 5 — 6^/2 cm 



longis, supra canaliculatis, subtus teretibus, ubique pilis minimis albido.-flavis 



sparsim obtectis, basi utrinque stipulis mediocribus lineari-lanceolatis vel inter- 



dum ovato-lanceolatis, subsinuoso-dentatis vel lobulatis (dentibus mucronulatis, 



circiter i mm altis, circiter 2 — 3 mm inter se distantibus), apice acutis vel 



acutissimis, pilis satis longis albido-flavis vel albis unicellularibus simplicibus 



subsericeis sparsim \'el rarissime dense obtectis, interdum glabratis, 3 — 4 mm 



longis, I — 1V2 mm latis); laminis ovatis vel ovato-lanceolatis, apice brevissime 



mucronato-acuminatis, basi rotundatis vel rarissime oblique subcordatis, mar- 



gine parte subintegra vel integerrima excepta ubique crebre sinuato-denticulatis 



(denticulis mucronulatis, circiter V4 — i mm altis, 3 — 4V2mm inter se distantibus), 



chartaceis vel submembranaceis subquintupli-pinninervis (nervis lateralibus 



4 saepe ceteris crassioribus ; 2 circiter ^/^ cm supra basin nascentibus usque ad 



medium laminae percurrentibus, 2 alteris 1^/2 — 1V4 cm supra basin nascentibus 



usque ad apicem arcuatim percurrentibus); inter nervos laterales subtus pro- 



minentes supra sulcis parum immersos reticulato-venosis venulosisque (venis 



venulisque subtus parum prominulis, supra vix conspicuis) ; folia suprema ovato- 



lanceolata, asymetrica, facie superiore conspecta pars dextera truncato-rotundata 



vel cordata, inferius descendens in petiolo, pars sinistra truncato-cuneata, minus 



descendens in petiolo, apice lanceolato-acuta, undique reticulato-venosa (nervis 



tertiariis subtus patentissimis, marginibus subregulariter et crebre dentatis, 



dentibus calloso-mucronatis) ; foliis omnibus supra parce pilis flavis minimis 



setosis obtectis vel glabratis, subtus iuventute parce arachnoideis, dein mox 



subhirsutis; laminis maximis 6 — 7^/2 cm longis, supra basin 3 — 3V2 cm latis. 



Capitula in cor3'mbis ad apicem ramorum inter folia fere occultata, rami flori- 



feri I — 3 inferiores 3 — 5-cephali ad axillas foliorum supremorum, reliqui 2-ce- 



phali \-el rarissime monocephali ad axillas foliorum lanceolatorum vel linearium 



cetero valde diminutorum. Bracteae lineari-lanceolatae vel lanceolatae, 10 — I5mn 



longae, 3 — 4 1/3 mm latae. PeduncuU et rami floriferi undique piHs minimis setosis 



horizontaliter patentibus sparsim obtecti vel plerumque subglabrati vel glaber-
