 usually dense spikes, the bracts sometimes brightly 

 colored. Calyx tubular, 4-cleft or sometimes split down 

 both sides. Corolla very irregular, the tube slender, the 

 limb 2-lipped; upper lip but little exceeding the inflated 

 3-plaited or 3-saccate lower one. Otherwise as in Castil- 



Filaments pubescent; galea bearded. 1. 0. purpurascens. 



Filaments glabrous; galea not bearded. 



Corolla 3-saccate their whole length. 2. 0. densiflorus. 



Corolla conspicuously 3-saccate, the sac as 



broad as long. 3. 0. parishii. 



1. O. purpurascens Benth. (Owl-clover.) Annual, erect, 

 rather stout, at length much branched from the base, 1.5-5 dm. 

 high, villous-pubescent; leaves with lanceolate base or body, and 

 laciniately 1-2-pinnately parted into narrow linear or filiform 

 lobes, or the upper palmately cleft; spike thick and dense; bracts 

 equaling the flowers, somewhat dilated, their lobes crimson-colored, 

 as are also the calyx and corolla; corolla 2.5-3 cm. long, the lip 

 moderately saccate, white-tipped, with yellow and purple markings; 

 galea densely purple-bearded on the back, incurved at tip; filaments 

 hairy. 



Common in sandy soils in the valleys and hills. 



2. O. densiflorus Benth. Annual, erect, simple or branched 

 from the base, 1-3 dm, high, soft-pubescent above; leaves linear 

 or linear-lanceolate, entire or with a few slender lobes; spike dense, 

 the lowest flowers sometimes distant; bracts about equaling the 

 flowers, 3-cleft into linear purple lobes; corolla 18-20 mm. long, 

 purple; lip moderately ventricose and somewhat 3-saccate for its 

 whole length, the teeth or lobes conspicuous, erect, oblong-linear; 

 galea narrow, puberulent or nearly smooth.

3. O. parishii Gray. Annual, nearly glabrous, about 2 dm. 

 high; leaves 3-5-cleft into linear-filiform divisions, or the lower 

 entire; floral ones similar, the lobes purple-tipped; spikes dense 

 and short; calyx-lobes lanceolate, obtuse, half the length of the 

 tube; corolla rose-purple, little pubescent in the throat; lip con-
