Annuum vel bienne. Radix tenuis, fusiformis. Caules complures ex eadem radice 
et subsimplices procumbentes vel arcuato-ascendentes, aut caulis unicus a basi ramosus 
ramis patentibus saepe decumbentibus; caules et rami subeylindrici (leviter striati), pilis 
gracilibus rectis patentibus hirsutulo-pubescentes, rarius subglabri (superne tamen pubes- 
centes), foliati, in racemos desinentes. Folia subtus pubescentia et margine (imprimis 
basin versus) remote ciliata; radicalia plerumque pinnatipartita rhachi anguste lineari 
integra, lobis paucis erecto-patentibus (45°) linearibus acutissimis distantibus (rarius 
folia subintegra linearia); caulina similia, sed minus divisa, saepius integra linearia, 
acuta, remota; superiora saepe latiora, basi subrotundata, remote serrata vel integerrima. 
Flores: sepala ovata, albo-marginata, saepe purpurascentia; petala calycem plerumque 
distinete excedentia, oblongo- vel obovato-spathulata, alba; stamina 4 mediana; glan- 
dulae 6 ovato-lanceolatae distinctae (mediana utriusque lateris lateralibus saepissime 
major) Racemi fructiferi elongati, laxiusculi, axi anguloso-suleato pubescente, pedicellis 
valde compresso-complanatis apice leviter dilatatis, e basi suberecta arcuato-paten- 
tibus vel arcuato-deflexis, inferioribus quam silicula saepe paulo longioribus, mediis ei 
+ aequilongis, superioribus brevioribus. Silicula ovato- vel elliptico-orbiculata, rarius 
late obovata, modice compressa, inferne valde convexa, superne plerumque leviter concava 
propter margines alares paulo incurvatos, apice circumferentia plerumque satis obtusa. 
manifeste sed anguste emarginata marginibus angulum acutum formantibus, lobulis alaribus 
obtusiuseulis convergentibus, stigmate in fundo emarginaturae subsessili; valvulae a basi 
ad medium anguste, superne latius (apice ad '/s—'/s| —'/4] longitudinis septi) alatae, 
glaberrimae laevissimae (enerviae) nitidae, saepe purpurascentes; septum (relative) latum 
(1:2!/»—3), late oblanceolatum, leviter asymmetricum (inferne magix convexum), stig- 
mate apieulatum. Semi»a anguste ovoidea (1: 1°/s), leviter compressa, fere laevia, immar- 
ginata, brunnea; embryo notorrhizus. 
Stengel meist 10 —20 cm lang. Grundblätter bis 7 cm lang, Spindel und Abschnitte 
1; —2 mm breit. Stengelblütter kürzer, oft etwas breiter. Kelch + 1 mm lang. Frucht 
4—4!/; mm lang, 3!/—4 mm breit. Same 1'/ mm lang, ®/«—1 mm breit.
