 ments along the petiole; stem-leaves few and small, with few short lobes. 

 Flowers white (or pink?), the sepals barely 1 line long. Petals, obovafe, 

 twice as long. Fruiting raceme loose and slender, 2 to 4 in. long, with 

 slender spreading pedicels. Pod 4 to 6 lines long, scarcely 1 line broad, 

 usually curved, narrowed towai'ds the base, glabrous or with a very minute

Some imperfect drv specimens have a slight rescmhhmce with the Europonn Sisymbrium 

 Thaliannm, to which P. Mueller was disposed to refer tlicni, but the latter plant is really very 

 different, having the undivided leaves, the flattened pods, the single-rowed seeds, and the 

 whole habit of an Aruhis, with the cotyledons less decidedly incnmhetit than in other Si- 

 si/mbria,
