Onopordon L. 



O. dissectum. — Nova spec. — Planta biennis, c. 6 — 8 decim. alta. Radix 

 crassa, fusiforrnis, cortice nigrescente munita, superne cicatricibus numerosis foliorum 

 anni prœcedentis notata. Gaulis foliosus, inferne simplex, superne ramis nonnullis 

 monocephalis axem primarium denique superantibus instructus, tota longitudine 

 alatus et indumento araneoso laxo albo-griseo vestitus. Alse circ. 6, parce griseo- 

 araneosse, diametro caulis c. duplo augustiores, in inferiore caulis parte continuas 

 crebreque lobatse lobis late triangularibus in spinam excurrentibus, in summa caulis 

 parte ramörumque ± interruptse saepeque ad spinas reductse; spinse diametrum caulis 

 ramorumque sequantes vel ssepius breviores, aciculares, vix vulnerantes. Folia omnia 

 supra parce arachnoidea, subviridia, glandulis minutissimis subsessilibus obsita, infra 

 indumento araneoso uberiore griseo-alba. Folia caulina inferiora petiolata, lamina 

 late ovato-lanceolata' usque ad rachin pinnatipartita; racbis inferne inter pinnas sub- 

 exalata, superne alis augustis loba tis instructa; pinnse utrinque 10 — 12, distantes, 

 lanceolatse, utrinque grosse et irregulariter iuciso-dentatse, in margine inferiore 

 segmento basilari magno lanceolato dentato prœditae; pinnarum lobi dentesque in 

 spinam acicularem 2—5 mm. longam vix vulnerantem product!. Folia caulina 

 media sessilia, semiamplexicaulia, decurrentia, ambitu oblongo-lanceolata, fere usque 

 ad rachin lobato-alatam pinnatipartita, segmentis anguste lanceolatis inciso-dentatis 

 in margine inferiore segmento basilari magno subulato-triangulari instructis; cet. ut 

 inferiora. Folia caulina superiora ramorumque sensim diminuta, anguste vel lineari- 

 lanceolata, profunde pinnatipartita, segmentis subulato-lanceolatis spinosis vel ad 

 spinam 3 — 5 mm. longam acicularem vix vel parum vulnerantem reductis. Cala- 

 thidia magna, absque spinis 3 — 4 cm. diametro, globosa, florendi tempore basi truu- 

 cata, postea leviter umbilicata, indumento arachnoideo laxo griseo-albo instructa. 

 Periclinii phylla exteriora lanceolata, sensim in spinam breviorem vel aequilongam 

 patentem vel reflexam producta; phylla media elliptico-lanceolata, subito in spinam 

 duplo ad quadruplo longiorem, rectam, patulam vel patentissimam, in facie superiore 

 fere usque ad apicem planam leviterque bifurcatam, ideoque pro ratione debilem 

 apice fragilem attenuata; phylla interiora lanceolato-linearia, sensim in spinam bre- 

 viorem mollem angastata ; phylla omnia marginibus minutissime serrulata, superiora 

 dorso quoque scabriuscula. Corolla c. 3 cm. longa, roseo-violacea; lacinise extus, 

 sicut etiam pars dilatata tubi, glandulis viscosis subsessilibus dense obsitee, etiam 

 duaa breviores parte dilatata tubi multo longiores. Staminum filamenta longitudine
