Nuttallia lobata Rydb. sp. nov. 
Perennial with a thick root; stems strict, glabrous or nearly so, 
white and shining, 3-4 dm. high; leaves 5-8 cm. long, 5-8 mm. 
wide, narrowly 6blanceolate, sinuately toothed or lobed with short 
triangular lobes; sepals lanceolate, acuminate, 8-10 mm. long; 
flowers diurnal, subtended by narrowly linear bracts; petals golden 
yellow, spatulate, obtuse, 12-18 mm. long; petaloid staminodia 
similar and almost as large; filaments numerous, the outer dilated ; 
capsule 15 mm. long, 8-9 mm. thick, acute, almost turbinate at the 
base; seeds suborbicular, broadly winged. 
This species is related to N. multiflora (Nutt.) Greene and N. 
pterosperma (Eastwood) Greene. It differs from the former in the 
narrow merely toothed or lobed not pinnatifid leaves; from the 
latter in the acute teeth or lobes of the leaves and the capsule, 
which is acute not rounded at the base, and from both in the 
glabrous stem.
