“ Thelypodium ovalifolium sp. nov. 
Perennial, perfectly glabrous: stems terete, 3-5 dm. high, 
ascending : earliest basal leaves about 5 cm. long, petioled with 
broadly oval blades, glabrous, entire, obtuse; the later ones ob- 
lanceolate ; stem-leaves sagittate, 2 cm. long, thick, sessile and 
clasping, with short rounded basal lobes : inflorescence elongated : 
sepals oblong, 3 mm. long: petals about 5 mm. long with spatu- 
late blades and slender claw: pedicels in fruit 4-5 mm. long, 
spreading: pods ascending, 1-2 cm. long and about 1 mm. wide, 
somewhat torulose. ; 
This species is perhaps most nearly related to 7: paniculatum, 
but differs in the short pods and the broad basal leaves.

‘Lepidium Georginum sp. nov. 
Apparently biennial, cespitose from a slender taproot, 1-2 dm. 
high: stems hirsute with short spreading hairs: basal leaves 1-5 
cm. long, deeply pinnately divided with ovate lobes ; stem-leaves 
similar or the upper oblanceolate and entire; all more or less , 
pubescent : inflorescence short: petals spatulate, slightly exceed- 
ing the sepals: pods pubescent, rounded oval, 4 mm. long, 
broadly winged above, forming at the apex two broadly ovate 
obtuse lobes, over 0.5 mm. long. 
This species is in habit nearest L. Wrightt with which it has 
been confused; but it is less hairy and the pods are those of Z. 
adictyotum.
