OREOCARYA 
Biennial or perennial, coarse. Flowers mostly white, in head-like or panicled ra- 
cemes. Calyx somewhat spreading in fruit, not circumsessile, persistent. Corolla with 
10 scales or glands at base within; throat with prominent folds within. Nutlets not 
keeled on the back, 3-angled; lateral angles acute but not winged, attached for the 
greater part of their length to a base; scar very slender, usually with transversely dilated 
base. (Gk. oros==a mountain, karyon=a nut; probably referring to the habitat.)

CRYPTANTHE NIEVITAS 
Annual, slender, hirsute or hispid, branching. Leaves small, narrow, alternate, en- 
tire (ours). Flowers in slender spikes or racemes, small, mostly white, sessile or on very 
short pedicels. Calyx hispid, closely embracing the fruit and usually dropping with it. 
Corolla small, often inconspicuous, rotate; tube not exceeding the calyx, usually with 
5 scales closing the throat. Stamens included. Ovaries 4. Nutlets attached from the 
upwards to various heights, smooth to papillose, sometimes with slight dorsal ridge, mar- 
gin sometimes acute or even winged. (Gk. kryptos—hidden, anthos—=a flower; because 












the corolla is sometimes very small.) 
mA. Calyx in fruit closed over the nutlets and falling with them, stiff-hairy; none of the 
— nutlets winged. 
- B. Nutlets rough or papillose, ovate, 3-angled, 4, equal.
