EASTWOOD. — MEXICAN SPECIES OF CASTILLEJA. 581 



2287 m., 3 June, 1899, Toivnsend & Barber, no. 449 (type, in hb. 

 Gray), also no. 250; same locality, E. W. Nelson, nos. 6227, 6101 

 (hb. U. S. Nat. Mus.). Dukango : Otinapa, E. Palmer, no. 367 in 

 part, July-August, 1906. The two equal segments of the calyx place 

 this in Euchroma, 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 cm. 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 nunc 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 Euchroma. 



33. C. Bryanti 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 cm. longa. — Proc. Cal. Acad. ser. 2, ii. 192 (1889), iii. 157. —In habit 

 of growth and foliaga this species resembles Orthocarpus, but the 

 flowers are those of Castilleja, approaching C. affinis, though much 

 smaller and less exserted. The pods are different from those of any
