* Castilleja Tweedyi. 



Perennial, from a woody caudex, 1-5 dm. high, finely puberulent 

 all over, or sometimes glabrate, the upper part somewhat villous ; 

 lower leaves linear-lanceolate, 3-nerved, 3-6 cm. long, the upper 

 ones broader, and often cleft, the floral ones often yellowish green, 

 tipped with bright red as in C. inineata ; calyx about 2 cm. long, 

 equally cleft before and behind, the clefts on the side shallow, less 

 than 5 mm. deep ; corolla 2.5 cm. long, greenish, tinged and margined 

 with red, the galea shorter than the tube, i cm. long ; lip green, with 

 broad lobes. 



The flowers in form and size resemble those of the preceding 

 two species, but are of a red, not scarlet, color. The most striking 

 difference is, however, in the tufted stems arising from a woody cau- 

 dex, while in the preceding species they are generally single and 

 from a running rootstock. It most resembles C. mincata, and has been 

 included in it. It does not form such large clumps as that species ; 

 the upper leaves are often cleft, while in C. mincata they are 

 nearly always entire, and the stem is often branched. The main dif- 

 ference is, however, m the flower, which in C. mincata has a smaller 

 corolla, scarcely 2 cm. long, and the galea fully as long as the 

 tube ; the lip in that species is very dark green and has narrower 

 incurved lobes. It grows in very big clumps, in open meadows in 

 the lower regions of Montana, while C. Tzvccdyi grows on hillsides 

 in the mountains, at an altitude of 2000-3000 m.
