ORTHOCARPUS TEXUIFOLIUS AND ITS RELATIVES 



Orthocarpus tenuifolius (Pursh) Benth. and its near allies com- 

 pose a group of species in which the bracts are strikingly and 

 abruptly different from the narrow leaves, being broad and more or 

 less colored, while they become papery and closely imbricated in the 

 fruiting spike. 



In the Synoptical Flora Doctor Gray recognized but two species, 

 which he increased to three in a revised treatment in the supplement 

 to the same work. Since then four other closely related species 

 have been described, namely, 0. cuspidatus Greene, O. barbatus 

 Cotton, O. olympicus Elmer, and 0. copelandii Eastwood. 0. olym- 

 piads seems indistinguishable from 0. imbricatus Torr., and 0. cope- 

 landii is the same as 0. cuspidatus. 



A recent examination of the material in the National Herbarium 

 is the basis for the treatment here proposed, in which one new species 

 is described, making six recognized in the group. They may be 

 distinguished by the following synopsis : 



Key to Species 



Galea uncinate at the tip ; bracts obtuse or some of the lower ones acutish, all 

 more or less purple-tinged. 



Corolla 25 to 30 mm. long ; galea much exceeding the lip ; fruiting calyx 

 firm, not scarious, the subulate-lanceolate teeth as long as the tube ; 



anther cells linear, curved O. pachystachyus. 



Corolla 12 to 15 mm. long; galea little longer than the lip; anther cells 

 oval. 



Fruiting calyx not scarious, its narrow teeth as long as the tube ; 

 corolla yellow, minutely pubescent ; capsule oblong, elliptic ; herbage 



scabrous and sparsely hirsute-ciliate O. tenuifolius. 



Fruiting calyx scarious. its triangular-subulate teeth much shorter 

 than the tube; corolla purplish, glabrous or minutely pruinose; 



capsule oval ; herbage merely puberulent O. imbricatus. 



Galea straight, its tip glandular-pubescent; bracts all acute, yellow or greenish. 



Calyx teeth not scarious, conspicuously ciliate ; corolla yellow, slender, the 



tip of the galea very pubescent ,0. barbatus.
