Allied with Lepidium strongylophyllum F. v. Muell. which however 
differs in the shape and the consistence of the leaves, the rather 
crowded flowers, the short pedicells etc.; it is also allied with L. pedi- 
cellosum F. v. Muell. but this species has a very different appearance, 
much longer pedicells etc. 
25. Lepidium rotundum DC. var. longistylosum Domin, nov. var. 
Differt a typo habitu multo robustiore, caulibus elongatis valde 
ramosis, ramis lateralibus fructiferis usque plus quam 30 cm longis, 
siliculis magnis orbiculatis valde convexis minus profunde emarginatis, 
lobis alaribus minus apertis, stylo emarginatura subaequilongo.

This variety may prove on further examination to be a distinct 
species. 
26. Lepidium eraemeum Domin, nov. spec. 
L. rotundo affine;? perenne (tantum specimina parte basali destituta 
visa) Caules ramosi, rami graciles glabri (i. e. ad angulos pilis minu- 
tissimis denticulati) subangulosi sublignosi elongati. Folia distantia 
crassiuscula angustissima linearia acutiuscula integra cirea 25 mm longa 
et 1 mm vel minus lata, Racemi elongati usque 3 dm (et sub fructu 
certe multo magis) longi erecti; axis subangulosa glabra. Flores laxi 
inconspicui sed structura iis L. rotundi haud dissimiles, Pedicelli di- 
varicati (plus minusve horizontaliter patentes) sub flore circa 3—3!/, mm 
sub fructu vix 4 mm longi crassiusculi rigidi papilloso-angulati siliculis 
breviores, Sepala anguste elliptica vix 2 mm longa. Petala alba ca- 
lyce subaequilonga sed angustiora, anguste lineari-oblonga basi ungui- 
culato-attenuata iis L. rotundi duplo angustiora. Stamina 2+4. Sili-
