C. G. Pringle, no. 13,659 ; in hb. U. S. Nat. Mus., near La Providen- 

 cia, altitude 1982-2440 m., E. W. Nelson, no. 4989 ; Sierra Madre, 45 

 km. north of Guanacevi, E. W. Nelson, no. 4766. 



49. C. Purpusi Brandegee, perennis suffruticosa hirsuta ; caulibus 

 niultis 1 dm. altis simplicibus ex rhizomatibus longis ramosis ; foliis 

 inferioribus lineari-lanceolatis obtusis vel acutis, basi subattenuatis 

 1.5-2 cm. longis 3-4 mm. latis ; foliis superioribus bracteisque trifidis, 

 segmento medio longissimo ; calyce antice profunde fisso, postice paulo, 

 segmentis integris vel emarginatis ; corolla 3.5 cm. longa exserta ; galea 

 tomentosa dorso viridi ; labio inferiore brevissimo, dentibus 3 acumi- 

 natis, medio breviore. — Zoe, v. 181 (1905). — Mt. Ixtaccibuatl, rocky 

 slopes above timber-line, C. A. Purpus, nos. 320 (type), 1711 (both in 

 hb. Univ. Calif., duplicates in hb. Gray). The bracts and calyx are 

 more or less tinged with red, but the entire plant becomes black in 

 drying. The leaves are rather thickly covered with loose spreading 

 long white hairs, and some of the upper leaves are trifid. 



50. C. pectinata Mart. & Gal., "fruticulosa pilosa; foliis pectinato- 

 subpinnatis, laciniis linearibus distantibus elongatis 2-3-jugis, bracteis 

 laciniato-pectinatis, floribus racemoso-spicatis, pedunculis et calycibus 

 pilosis. — Folia pollicaria pectinato-laciniata, flores rubri similes flori- 

 bus Castillejae integrifoliae L. ; sed pedunculati. — Affinis Castillejae 

 laciniatae Hook. Dans les forets de pins de la Cueva del Temascal, au 

 pic d'Orizaba, de 9500 a 12,500 pieds (limites de la vegetation phane- 

 rogame). Fl. rouge- vermilion. Aout." ■ — Bull. Acad. Brux. xii. pt. 2, 

 27 (1845) ; Walp. Rep. vi. 651 ; Hemsl. 1. c. 462. — C. Orizabae Benth. 

 in DC. Prodr. x. 533, is founded partly on the same number (1074) 

 in Galeotti's collection, also on Linden, no. 223. Bentham gives 

 these additional characteristics under C. Or'tzabae, — " canescenti- 

 hispidula, foliis inferioribus integris linearibus sublanceolatisve, superi- 

 oribus dilatatis incisis, fioralibus vix apice coloratis, racemo laxo, calyce 

 elongate amplo hinc fisso postice obtuse 2-4-dentato, corollae galea 

 tubo suo multo longiore, labii lobis brevibus acuminatis. Habitus fere 

 C. integrifoliae sed folia pleraque incisa lobis elongatis et flores multo 

 majores. Calyx 15 lin. longus. Corollae galea dorso villosa, calycem 

 lineis 5-6 superans." In hb. Gray the species is represented by a 

 doubtfully identified specimen collected in Guatemala : Volcan de 

 Agua, Depart. Zacatepequez, altitude 3670 m., April, 1890, John Don- 

 nell Smith, no. 2146. 



51. C. fissifolia Linn, f., herbacea quandoque suffruticosa ; caulibus 

 erectis parum ramosis foliosis pubescentibus ; foliis sessilibus patentis- 

 simis, basi ovatis integris, apice pinnatifidis, laciniis patentibus obtusis 

 fere alternis utrinque pubescentibus subtrinerviis j floribus versus apices
