Perenne (sec. Battand. & Trab. 1. c. etiam bienne). Radix crassa, superne plerumque 
ramosa, rosulas foliorum basilarium 2—3 emittens, collo rudimentis fibrosis foliorum 
delapsorum vestita. Caulis in centro rosulae basilaris solitarius, saepius erectus, plerumque 
crassus et rigidus, cylindrieus (leviter anguloso-striatus), superne (ut rami) pilis albis 
gracillimis elongatis + patentibus saepe leviter flexuosis pubescens, foliatus, superne 
corymboso-ramosus, ramis et ramulis in racemos abeuntibus. olia glabra, angustissime 
membranaceo-marginata, interdum leviter coriacea; basilaria longe petiolata, oblonga vel 
obovata, integra vel sinuato-repanda vel lyrato-pinnatipartita; caulina media et superiora 
sessilia, triangulari-lanceolata, plerumque acuta, margine grosse dentata vel (saepius) 
leviter repando-undulata vel integerrima, basi sagittata amplexicaulia auriculis saepe 
elongatis. Flores conspicul, in racemis confertis (sed propter sepala et petala et stamina 
[sine antheris!] satis diu persistentia + elongatis); sepala anguste elliptica, fere a basi 
flavo-margmata; petala flava, calyce 1?/s-plo longiora, distincte unguiculata, lamina late 
obovata apice rotundata, in unguem ea paulo longiorem attenuata; stamina 2 -L 4, fila- 
mentis anthera lineari-oblonga, deflorata recurvata, 4—5-plo longioribus; glandulae 6 
triangulari-ovatae brevissimae (calycis ca. '/ıs longitudine aequantes), quarum medianae 
satis distinctae (propter filamentorum medianorum bases distantes); ovarium anguste ellip- 
ticum, alatum, plerumque emarginatum, stylo eo duplo vel triplo breviore terminatum. 
Racemi fructiferi elongati, satis densi, axi anguloso-striato pilis albis gracillimis satis 
longis + patentibus villosulo vel pubescente, pedicellis satis crassis leviter angulosis pilis 
eorum diametrum longitudine fere attingentibus pubescentibus, patentibus (60 ?), rectis 
vel leviter extrorsum arcuatis, silieula ispsa (excl. stylo) paulo brevioribus (septo sub- 
aequilongis). Silicula ampla, late elliptica vel late ovato-elliptica, utrinque circumferentia 
obtusiuscula, a basi conspicue et sensim latius (apice ad '/s fere longitudinis septi) alata, 
facie inferiore valde convexa, facie superiore propter margines alares incurvatos concava, 
apice retusa vel emarginata, stylo conspicuo exserto apiculata; valvulae maturae laeves 
subnitidae; replum basi valde dilatatum et incrassatum; septum elliptico-lanceolatum, 
semilunato- sursum curvatum, in stylum conspicuum (septi longitudinis !/2-'/s adaequantem) 
acuminatum. Semina ovoidea, leviter tantum compressa (sectione transversali ovato-elliptica), 
distincte alveolato-papillosa subimmarginata, obscure fusca; embryo normalis notorrhizus.
