EASTWOOD. — MEXICAN SPECIES OF CASTILLEJA. 581 
2287 m., 3 June, 1899, Townsend & Barber, no. 449 (type, in hb. 
Gray), also no. 250; same locality, H. W. Nelson, nos. 6227, 6101 
(hb. U. S. Nat. Mus.). Durango: Otinapa, 2. Palmer, no. 367 in 
part, July-August, 1906. The two equal segments of the calyx place 
this in Luchroma, but these parts are sharply cleft as in Hemichroma. 
The lower lip of the corolla resembles that of C. nervata. 
32. C. ctenodonta, n. sp., perennis glandulari-pilosa; rhizoma 
gracili; caule simplici recto gracili 2-3.5 dm. alto; foliis infimis 
non rosulatis sed imbricatis lanceolatis integris trinerviis 3 em. longis 
5 mm, latis, apice acuminatis ; foliis ceteris imbricatis vel distantibus 
lanceolato-acuminatis pectinatis cum lobulis filiformibus 1-5 mm. longis 
distantibus 2-8 mm., saepe pectinato-dentatis, basi cordato-amplexi- 
caulibus et paulo decurrentibus ; spicis capitatis non-numquam pedun- 
culatis et demum elongatis ; bracteis supremis pectinatis vel anguste 
laciniatis quam flores brevioribus, apice coccineis ; floribus sessilibus 
paucis subdivaricatis ; calyce coccineo nunc paulo longiore nune corolla 
breviore, segmentis acuti 1-2 mm. in altitudinem bifidis; corollae galea 
obtusa exserta 4-7 mm. dorso barbata ; labio inferiore non viso ; stylo 
exserto 1-2 mm. gracili; stigmate clavato integro ; capsula elliptica 
acuta. — Oaxaca: wet meadows, Sierra de Clavellinas, altitude 2745 
m., 16 October, 1894, C. G. Pringle, no. 4986 (type, in hb. Gray). — 
This number was distributed as C. pectinata, but cannot be that 
shrubby plant, nor is it to be classed in the same alliance. It more 
nearly approaches C. patriotica, but differs from that well-marked 
species in leaves, pubescence, and flowers. It is a more slender plant 
with simple stems. There are features which ally it to C. minor, such 
as, the narrow segments of the calyx-divisions, the slender red-tipped 
divisions of the uppermost bracts, and the conspicuously colored lower 
lip of the corolla. The leaves are typically pectinate with the rhachis 
lanceolate. It is doubtfully placed in Huchroma. ea 
33. C. Bryanri Brandegee, annua 1.5-3 dm. alta divaricate pilosa 
ramosa, ramulis gracilibus rectis ; foliis inferioribus linearibus integris, 
ceteris pinnatisectis, laciniis 3-7 linearibus acutis; floribus spicatis 
apice confertis infra elongatis et interruptis ; bracteis similibus foliis 
superioribus, apice coccineis vel ochroleucis ; calycis segmentis 7-9 mm. 
longis 2-3 mm. in altitudinem bisectis, laciniis lanceolatis ; corolla 
calycem aequanti 15-18 mm. longa, galea brevi, labii inferioris lobis 
brevibus incurvatis; capsula oblongo-cylindracea vel subellipsoidea 
1 om. longa. — Proc. Cal. Acad. ser. 2, ii. 192 (1889), iii. 157. —In habit 
of growth and foliage this species resembles Orthoca but the 
flowers are those of Castilleja, approaching C. affinis, though much 
smaller and less exserted. The pods are different from those of any
