Lunaria annua L. Sp. PL 653. 1753. 

 Lunaria biennis Moench, Meth. 126. 1794. 



Resembles the preceding species when in flower, 

 but the root is annual or biennial. Siliques elliptic 

 or broadly oval, iz'-2' long, i' wide or rather more, 

 rounded at both ends; seeds suborbicular, cordate, 

 about as long as wide. 



Escaped from gardens in southern Ontario, south- 

 western Connecticut and eastern Pennsylvania. Both 

 this species and the preceding are occasionally culti- 

 vated for their remarkable large pods, which are 

 gathered for dry bouquets, the valves falling away at 

 maturity and leaving the septum as a shining membrane.

39. SINAPIS L. Sp. PI. 668. 1753. 



Annual or biennial, usually erect, branching more or less hispid herbs, with pinnatifid 

 or lobed leaves, and rather large, mostly yellow flowers in terminal racemes. Siliques linear, 

 nearly terete, constricted between the seeds, sessile in the calyx, smooth or densely hispid, 

 tipped with a very long flat sword-like or angled beak which often contains a seed near 

 its base, the valves 3-nerved. Seeds subglobose, in one row in each cell, not winged nor 

 margined. Cotyledons conduplicate. [Name Greek, said to come from the Celtic for turnip.] 



About 5 species, natives of southern Europe. Type species : Sinapis alba L. 



Leaves lyrate pinnatifid ; fruiting pedicels 4"- 5" long. i. S. alba.

Brassica alba Boiss. Voy. Espag. 2 : 39. 1839-45. 



Erect, annual, i-2 high, more or less pu-

 pinnatifid or pinnate, with a large terminal 

 leaflet or lobe and several pairs of smaller 

 lateral ones, dentate all around; uppermost 

 leaves lanceolate or oblong, often merely 

 dentate, short-petioled ; flowers yellow, 7"- 

 9" broad; pedicels rather stout, spreading, 

 5 "-7" long in fruit; pods spreading or 

 ascending, terete, constricted between the 

 seeds ; beak flat, equalling or sometimes longer 

 than the rest of the pod ; seeds light brown. 



In waste places and fields, occasional, mostly 

 escaped from cultivation. Adyentive from Eu- 

 rope. Native also of western Asia. Senvie. Ked-
