Perenne. Radix valida, in ramos crassos divisa. Cawlis plerumque unicus, elatus, 
erectus, strictus, anguloso-sulcatus, pilis gracilibus imprimis in inflorescentia leviter 
pubescens, praeterea primo intuitu glaber, ramosus ramis suberectis, ut ramuli in race- 
mos abeuntibus. Folia basilaria longa, longe petiolata, lanceolata vel oblanceolata, sub- 
integra vel serrata vel lyrato-pinnatim incisa, subglabra (margine tantum pilis gracilibus 
rectis subeiliata) aut villoso-pubescentia pilis ejusdem formae; caulina inferiora saepe 
apicem versus incisa; media margine plerumque pilis rectis oblique erecto-patentibus 
ciliata; longe lineari-lanceolata vel linearia, remote minutissimeque serrata vel 
integerrima, acuta, basi plerumque subdilatata sessilia, interdum fere rotundata; summa 
linearia vel lineari-subulata i. e. e basi latiore sensim attenuata. Flores: sepala ovata, 
albo-marginata, caduca; petala oblongo-spathulata, in unguem brevem attenuata, calycem 
paulo superantia, albida; stamina 2 vidi; glandulae 4 forma mire variabili, mox late 
triangulari-ovatae valde complanatae, mox bifidae, mox quasi bipartitae lobis elongatis 
subeylindrieis. Racemi fructiferi satis densi, axi anguloso-suleato plerumque pubescente, 
pedicellis leviter angulosis, e basi suberecta plerumque arcuato-patentibus, siliculae sub- 
aequilongis. Silicula elliptica usque orbiculata, compressa, apice distincte alata et emar- 
ginata, stigmate in fundo emarginaturae subsessili; valvulae carinatae, a medio alatae, 
glaberrimae et laeves, subnitidae; septum late oblanceolatum, basim versus contractum 
(leviter panduriforme), subsymmetricum, stylo apieulatum. Semina anguste ovoidea, leviter 
compressa (sectione transversali subtriangulari), sublaevia, saepe anguste alato-marginata, 
fusca; embryo notorrhizus, cotyledonibus — praeter plicaturam basalem — in medio 
' leviter transverse plicatis.
