S4 Muhlenbergia, Volume 5 



about 12000 feet. This proposed species is distinguished by its 

 more erect and stouter, stiffer habit, C. confusa being- taller, more 

 slender, and rather weak and lax; by the much more abundant 

 and stiffer pubescent stems, the smaller flowers and bracts, and 

 the more divided bracts. 



A rather interesting variant of this plant was noted. In 

 one clump growing with the common scarlet-bracted form were 

 found a number of plants with bright yellow bracts; otherwise 

 they did not differ from the type form. This same mutant was 

 collected by Mrs. Bartlett in 1905 in about the same locality. 

 It is not the same as C. confusa x acuminata described by Pro- 

 fessor Cockerell, although the plant there called C. confusa is 

 the one here described as new. 



In the Sacramento and White mountains of southern New 

 Mexico is another Castilleja that has long been known as C. 

 affinis H. & A. That species was first collected in California, 

 and one hardly expects to find a Californian plant in New Mex- 

 ico. Careful examination has convinced the writer that the 

 New Mexican plant is distinct, and it is here described as 



Castilleja Wootonii sp. nov. 



An erect perennial: steins stout, often reddish, single or 

 clustered, 6 to 10 dm. high, simple below but amply branched 

 above, glabrous in most parts, but soft pubescent near the base 

 and with abundant, short, white, villous pubescence upon the 

 inflorescence: leaves simple or frequently with two linear, acu- 

 minate, divergent lobes, when simple linear-lanceolate, acute, 

 7 cm. long or less, bright green, mostly glabrous, 3-nerved: 

 bracts 25 mm. long or less, with two or rarely four divergent, 

 linear, lateral lobes which are about twice as long as the termi- 

 nal one, the terminal lobe narrow, entire, and acute to obtuse) 

 short villous along the veins, scarlet above for half their length: 

 flowers short pedicel led, numerous in a spike which is dense and 

 short at first but later becomes elongated: calyx 25 mm. long or 

 less, "cleft in front for one-third its length or more, behind about 

 half as deeply, the lobes each with two linear-lanceolate, acumi- 

 nate teeth, short villous along tin- veins: corolla 30mm. long or
