Tlu- first plant collected In the writer during the summer 

 of 1908 in the Pecos River National Forest was a Castilleja. It 

 is closely related to C. confusa Greene, but the specimens were 

 finally distributed as a new species. Through carelessness the 

 name assigned to it on the labels was one already used by iJr. 

 E. L. Greene. I wish to describe it here under another name: 



Castilleja inconstans sp. now 



Perennial: stems mostly solitary, stout, simple at the base 

 but usually branched above, stiffly erect, 5 dm. high or less, with 

 abundant, short, stiff pubescence throughout, or sometimes al- 

 most glabrous about the middle iuternodes: leaves linear-lanceo- 

 late, entire, 60 mm. long and 9 mm. wide or mostly smaller, 

 rather bright green, acute or acuminate, 3-nerved, scabrous es- 

 pecially beneath, the upper leaves usually slightly wider than 

 the lower ones: bracts about as wide as the leaves but shorter, 

 15 to 25111111. long, with two pairs of long, linear, acute lobes, 

 the central lobe being acutish and conspicuous])- toothed, the 

 lateial lobes often toothed also, scabrate or short-villous, scarlet 

 for about half their length: calyx about 15 mm. long, almost 

 equally cleft before and behind, the divisions each with two 

 long, linear-lanceolate, attenuate teeth: corolla exserted, about 

 20 mm. long, galea much shorter than the tube, the lip very 

 short and inconspicuous: capsule ovoid, about 1 cm. long, with 

 a beak about 2 mm. long, glabrous. 



Type collected at Winsor's ranch, on the headwaters of the 

 Pecos river, June 29, 1908, Standley 4000, altitude about 8400 

 feet. The plant is common in this region, growing on rather 

 sunny hills under pines or even higher up among the aspens. 

 ( Hher collections seen, all from this same region, are as follows: 

 Rio Pecos two miles below Winsor's 1908, Standley 4244; Har- 

 vey's upper ranch, 1908, Standley 4687, altitude 9600 feet; Santa 

 Fe mountains, 1898, Maltby and Coghill 2; upper Pecos river, 

 1904, Mrs. //'. //. Bartlett; Harvey's ranch, 1899, CockerelL 



( '. confusa is common in this same region, but is readily 

 distinguished in the field by its different aspect. It reaches 

 higher levels, too, for the writer collected it on Pecos Baldv at
