Lunaria annua I,. 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 ellip- 
tic or broadly oval, 114’-2’ long, 1’ wide or rather 
more, rounded at both ends; seeds suborbicular, 
cordate, about as long as wide. 
Escaped from gardens to roadsides in southwestern 
Connecticut. Both this species and the preceding are 
occasionally cultivated for their remarkably large pods, 
which are gathered for dry bouquets, the valves falling 
away at maturity and leaving the septum as a shining 
membrane. May-June. 
21. SELENIA Nutt. Journ. Acad. Phila. 5: 132. 1825. 
Annual tufted glabrous herbs, with pinnatisect leaves, and racemose leafy-bracted yellow 
flowers. Sepals spreading. Petals narrow, erect, with 10 hypogynous glands at their bases. 
Silique stalked, very flat, oblong, narrowed ateachend. Valves nerveless, thin, finely veined, 
dehiscent. Style long, slender. Seeds few, in 2 rows in each cell of the pod, orbicular, flat, 
broadly winged, free from the septum. Cotyledons accumbent. [Greek, moon, from the 
resemblance of this genus to Luwnaria. | 
_Two or three species, natives of the south-central 
United States and northern Mexico. 
1. Selenia aurea Nutt. Selenia. 
(Fig. 1741.) 
Selenia aurea Nutt. Journ. Acad. Phila. 5:132. 1825. 
Stems simple, numerous, 2’-8’ high. Basal leaves 
1/-2’ long, narrow, I-2-pinnatifid into numerous ob- 
long dentate segments; stem-leaves similar, smaller; 
bracts of the raceme pinnatifid, resembling the upper 
leaves; flowers 3//-4’’ high, numerous; pedicels 5//-7/’ 
long in fruit, spreading or ascending; pod 6//-10’’ 
long, 2’’-3’” broad; style 2’’ long, very slender. 
In open places, Missouri and Kansasto Texas. March- 
April. 
22. LEAVENWORTHIA Torr. Ann. WyciiN. Ys 4: 87s. =1837- 
Low annual glabrous scapose herbs, with lyrate-pinnatifid persistent basal leaves, and 
few or solitary terminal flowers. Petals wedge-shaped. Siliques flat, broadly linear or ob- 
long, short-stipitate; valves dehiscent, nerveless, finely reticulate-veined. Seeds in 1 row in 
each cell of the pod, flat, winged or margined; radicle short, slightly bent toward the coty- 
ledons. [In honor of Dr. M. C. Leavenworth, U. S. A.] 
A genus of about 4 species, natives of southeastern North America. 
Pods not constricted between the seeds. 1. L. uniflora.
