vel 2-3-lobatis pruinosis; calycis segmentis 1 cm. longis 3 mm. latis 

 emarginatis pruinosis tubum aequantibus; galea apice acuta 1 cm. longa 

 purpurea glandulare puberulenti ; labio inferiore membranaceo, laciniis 

 linearibus acutis 2 mm. longis ; stylo crasso ; stigmate globoso 1.25 mm. 

 diametro vix exserto ; capsula elliptica acuta compressa. — Durango : 

 Otinapa T July-August, 1906, E. Palmer, no. 361 (type, in hb. Gray). 

 The peculiar pruinose appearance of the inflorescence is due to the 

 white puberulence closely covering the purplish bracts and flowers. 



7. C. Palmeri, n. sp., sparse pilosa et glandulari-puberulens ; cauli- 

 bus 1-2 simplicibus rectis 1.5 dm. altis; foliis radicalibus imbricatis 

 caulinis lanceolatis 2-3 cm. longis 1-3 mm. latis trinerviis, basi amplexi- 

 caulibus 5-10 mm. latis, apice obtusis vel acutis, margine integris vel 

 undulatis ; spicis flavis brevibus compactis, fructiferis elongatis ; bracteis 

 flores sessiles superantibus vel aequantibus spatulatis 2-3 cm. longis 

 integris, apice rotundatis ; calyce fisso 7 mm., laciniis emarginatis 5 mm. 

 latis ; corolla 14 mm. longa, galea acuta, dorso glandulari-puberulenti, 

 calycem superanti ; labio inferiore membranaceo protuberanti, lobis 

 subulatis acuminatis 2 mm. longis glandulari-ciliatis ; stigmate bilobato 

 crasso paulo exserto ; capsula ovato-acuminata compressa ; seminibus 

 foveolatis cum testa membranacea. — Durango : Otinapa, July-August, 

 1906, E. Palmer, no. 376 (type, in hb. Gray). This species is related 

 to C. macrostigma, differing in pubescence, densely flowered spike, and 

 large bracts ; from C. angustata it differs in pubescence, stigma, foliage, 

 and flowers. There are resemblances to C. glandulosa chiefly in the form 

 of the spike, but the bracts in C. Palmeri are rounded at apex rather 

 than rhomboid. The corolla is quite dissimilar, the lower lip with three 

 long almost equal divisions, and the body extending outward like a shelf, 

 being very different from the trisaccate lower lip of C. glandulosa with 

 its short divisions separated by the folds forming the sacs. 



8. C. angustata (Robinson & Seaton), n. comb., caulibus 1-2 rectis 

 gracilibus purpurascentibus 1-1.5 dm. altis, basi squamulosis, inferiore 

 parte minute adpresso-pubescenti, superiore parte spicisque albo- 

 tomentosis; foliis integris linearibus 2-4 cm. longis 1-3 mm. latis; 

 bracteis lanceolatis acutis flores subaequantibus, supra viridibus gla- 

 brescentibus, subter albo-tomentosis, confertis cum floribus in spicis 

 brevibus; calycis segmentis bidentatis vel crenatis albo-puberulentibus; 

 corollae galea calycem paulo superanti, apice acuta, dorso glandulari- 

 puberulenti ; labio inferiore non protuberanti, laciniis 3 lineari-obtusis 

 ciliatis 1.25 mm. longis, sinubus angustis; stigmate crasso bilobato, paulo 

 exserto ; capsula ovato-oblonga acuta 5-7 mm. longa. — G. pallida
