EASTWOOD. — MEXICAN SPECIES OF CASTILLEJA. 571 



C. G. Pringle, no. 4117 (type, in hb. Gray). — This is well distinguished 

 in the group in which it has been placed by the almost lanate pubes- 

 cence. Often at the base of the stem there is a peculiar thickening due 

 to the old crowded leaf-bases. The leaves are probably present during 

 the wet season. 



9. C ornata, n. sp., caulibus 1-2 rectis simplicibus 1.7-2.5 dm. altis 

 glandulari-pilosis striatis ; foliis lanceolatis vel oblongis, apice acutis 

 vel obtusis, basi amplexicaulibus, margine integris vel crispi-undulatis, 

 2-3.5 cm. longis 2-6 mm. latis trinerviis ; foliis radicalibus rosulatis, 

 caulinis propinquis, supremis apice coccineis ; floribus bracteisque con- 

 fertis in spicis ornatis ; bracteis spatulatis glandulari-puberulentibus, 

 apice rotundatis vel rhomboideis 2-2.5 cm. longis 5-10 mm. latis 

 calycem excedentibus ; calyce fisso 1 cm., segmentis undulatis 5 mm. 

 latis ; galea exserta 5 mm., apice acuta, dorso viridi puberulenti, antice 

 albo-membranacea ; labio inferiore trisaccato membranaceo, laciniis 

 subulati-acuminatis 2 mm. longis ; stylo filiformi exserto, stigmate 

 crasso bilobato, in fructu galea stigmateque contortis ; capsula oblongo- 

 ovata acuminata compressa 1 cm. longa. — Chihuahua : near Colonia 

 Juarez, Sierra Madre, June-July, 1899, E. W. Nelson, no. 6073 

 (type, in hb. Gray). This approaches more closely to C. glandulosa than 

 any other species and resembles it in the trisaccate lower lip with the 

 divisions separated by the folds forming the three sacs below. It has 

 different pubescence and generally obtuse leaves. C. glandulosa does 

 not appear ever to have the basal leaves rosulate, but their persistence 

 in this species may be due to a season or locality of greater moisture. 



10. C. communis Benth., pilosa et hispida ramosa alta ; caulis in- 

 feriore parte squamulose tuberculata ; foliis lanceolatis integris basi 

 angustatis apice acutis vel obtusis ; spicis elongatis basi interrupts ; 

 bracteis apice coloratis vix dilatatis flores parum aequantibus apice 

 glandulosis viridibus ; corolla non exserta ; capsula lata obtusa siccitate 

 nigra. — Benth. in DC. Prodr. x. 529; Hemsl. Biol. Cent. -Am. Bot.
