margins, conspicuously exserted beyond the calyx and floral bracts; lip 
usually dark green, 3-lobed, about one-fourth the length of the galea, 
commonly protruding through the anterior fissure of the calyx: mature 
capsule oblong, 7 to 8™™ long, abruptly acuminate or subapiculate, strongly 
compressed laterally, glabrous: seeds about 1.5™™ long, yellowish-brown.

Miss Edith"M. Farr, nos. 567, 568 (type), 569, 570, 571, 572, 573, 574 (form 
with yellowish inflorescence slightly tinged with red or pink), 575, 576. Type 
in hb. Field Museum and hb. Univ. of Penn. 
The suite of specimens here cited shows considerable variation in color and 
to some extent variation in foliage, but all have the same habit and technical 
characters of the flower. The species apparently has its nearest affinity with 
Castilleja Elmeri Fernald, from which it differs in being glabrous or essentially 
so below, in having a more slender inflorescence, narrower floral bracts, and a 
more conspicuously exserted corolla with a somewhat longer galea. The pur- 
plish cast of the entire plant with the galea extending well beyond the crimson 
°r purplish bracts and calyx renders this an attractive species and easily dis- 
tinguished among its numerous allies. 
_ Senecio (§AuRer) Farriae Greenman, n. sp.—An herbaceous peren- 
Malt to r,sdm high: stem erect or ascending, branching from near the 
base, glabrous except for a persistent white tomentum in the leaf axils; 
branches few, relatively long and terminated by a single head: basal 
leaves ovate to slightly obovate, the blade 1 to 3°™ long, 1 to r.5°™ broad, 
rounded at the apex, crenate-serrate to subentire, contracted at the base 
into a narrowly winged petiole equaling or exceeding the blade, glabrous 
or nearly so; the lower stem leaves sublyrate or more or less irregularly 
Pinnatifid, the upper reduced to entire bracts: heads about 1°™ high, 
radiate: involucre campanulate, slightly calyculate, tomentulose at the 
base; bracts of the involucre usually 21, linear-lanceolate, about 8"™ 
long, nearly or quite equaling the flowers of the disk, acute, reddish tipped: 
ray-flowers 12 to 14; rays orange-yellow; disk-flowers numerous.
