 row; calyx lobes oblong and 2-cleft at the apex or to below the middle; corolla an inch or

10. ORTHOCAEPUS, Nutt. 



Chiefly distinguished from Castilleia by the upper lip of the corolla (galea) which but 

 little, if at aU, surpasses the usually more conspicuous and inflated 1-3-saccate lower 

 Up.

 bearing 3 conspicuous teeth; the galea broadish or narrow; stigma capitate; anthers at, 

 S-celled; bracts with colored tips.

ventricose ; its teeth erect. 



1. O. attenuatus, Gr. Slender, strict, a span or two high, mostly simple; leaves 

 linear and attenuate, often with a pair of filiform lobes; spike slender; lower flowers 

 scattered; bracts with slender lobes barely white-tipped; coroUa narrow, half an inch 

 long, white or whitish; narrow teeth of the purple-spotted lip nearly equaling the galea. 



2. O. densiflorus, Benth. Erect or difiiisely branched from the base 6 to 12 inches 

 high; spike dense, many flowered, at length cylindrical, or lowest flowers rather distant; 

 bracts 3-cleft, about equaling the floweis, their linear lobes purple and white; coroUa 

 from 8 to 12 lines long, the tips usually purplish, the teeth of the lip shorter than the 

 galea. 



3. O. castiUeioides, Benth. At length diffuse and corymbosely branched; leaves from 

 lanceolate to oblong, usually laoiniate; the upper and the bracts cuneate-dilated and 

 inoisely cleft, green or the obtuse tips whitish or yellowish; spikes dense, short and thick:
