I. X Cirsium Kornhuheri nova hybrida 



(pannonico X rivulare). 



Gaulis hypogaeus oblique descendens, radiculis adventivis copiosis, 

 omnino non incrassatis, ßiformibus instructus, epigaeus 50— 80cm. altus, 

 Simplex vel raro ramo superne instructus, ad medium circiter decrescenti- 

 foliatus, superne subaphyllus, inferne angulatus et breviter hirtulus, superne 

 tenuiter stridlatus (saepius purpurascens) atque parcius sub capitulo densius 

 floccosus. 



Folia ambitu lanceolata, superiora elongato-lanceolata, acuta, in pagina 

 superiore laete viridia, in inferiore subpallidiora, trichomatibus rigidulis bre- 

 vissimisque utrinque asperulata, ceterum lamina solum in nervis pilosula non 

 floccosa in margine autem breviter spinuloso-ciliata, modo subintegra hinc inde 

 dentata, modo varie lobata vel piinnatifida; folia basilaria et infima caulis 

 in petiolum laminam aequantem vel parum breviorem attenuata, subintegra, 

 folia inferiora breviter petiolata (cum petiolo 100— 130 min. : 25 -30 mm.) 

 pinnati lobata vel pinnatifida, lobis (vel segmentis) in basin et apicem foliorum 

 versus diminutis, 4—7nis utrinque, triangulär i-lanceolatis, acuminatis, inte- 

 griusculis vel hinc inde dentatis, media et superiora sessilia, breviter sed 

 valde conspicue ad 5— 8mm. decurrentia, obsolete dentata, summa integerrima, 

 anguste lineari-lanceolata vix decurrentia supra basin caulem semiamplectentem 

 leviter constricta, iis Cirsii pannonici (L. fil.) igitur simillima. 



Capitulum subsolitarium (plerumque capitula abortiva in axillis fo- 

 liorum diminutorum superioris caulis inveniuntwr) quoad magnitudinem ea Cirsii
