404 PROCEEDINGS OP THE AMERICAN ACADEMY 



At the Frailes, above Batopilas, at over 7,000 feet : corolla (puberulent 

 externally) said to be " bright carmine," Palmer, 258. 



Lamourouxia coccinea. Hemispadoa, Z. eorrfa^^e soror, tantum 

 puberula; foliis ovato-oblongis basi lata subcordata arete sessilibus 

 crebe serratis, superioribus spicas laterales sa^pius fulcrantibus ; caly- 

 cis vix visciduli dentibus tubo baud longioribus ; corolla Lxte coccinea 

 tubulosa (nee ventricosa) sesquipollicari extus tenuissime puberula, 

 labiis tubo dimidio brevioribus, galea oblonga recta ; filamentis posticis 

 tenuibns anantheris glabris ; capsulis parvulis (lin. 4 longis) calyce 

 fere inclusis, — Rocky hills near the city of Chihuahua, Pringle, 656. 



Lamourouxia hyssopifolia. L. longiflorce perafRnis, " frutes- 

 cens tripedalis," sed ramis floridis gracilibus herbaceis foliosissirais ; 

 foliis spathulato4anceolatis (majoribus vix ultra-poUicaribus), floralibus 

 parvis ; floribus patentissimis ; calycis lobis tenui-subulatis tubo suo 

 brevioribus ; corolla miniata glabra antice ventricosa vix ultra-pollicari, 

 galea lata spathacea obtusissima edentata. — At the Frailes in the 

 mountains above Batopilas, at about 7,000 feet. Palmer, 260. Corolla 

 said to be crimson, but seemingly pure red. — L. longijlora is not very 

 well named, the corolla in our specimen from Hartweg being only an 

 inch and a half long; in those of Seemann's collection hardly of that 

 length, but rather more ventricose ; in both the calyx4obes are elon- 

 gated and filiform. The present species has a more gibbous ventricose 

 as well as smaller corolla, and the slightly recurved galea is not at all 

 notched or toothed, 



Castilleia Mexicana. C sessihyiorce proxima, hirsutula, co- 

 rollfe (" ochroleucse viridulo et roseo parum tinctjie ") tubo pra4ongo 

 labioque ampliori insigiiis. — Orthocarpus Mexicamis, Hemsl. Biol. 

 Centr.-Am. Bot. ii. 463, t. 63, f. 1-6. — I see no good reason for 

 referring this and the closely related C. sessilifiora to Orthocarpus ; 

 certainly none in any particular affinity with Orthocarpus australis. 

 The lips of the corolla are no more nearly equal than in C. pallida ; 

 bifid calyx-lobes are common in the genus ; and the lip of the corolla 

 is not at all saccate in the present species. The elongated corolla-tube 

 is, indeed, peculiar, but that is not particularly characteristic of Ortho- 

 carpus. Cool hillsides west of Chihuahua, Pringle, 209. 



Pedicularis angustifolia, Benth. PI. Hartw. 22. Summit of 

 the higher mountains above Batopilas, at 8,800 feet. Palmer, 326. 



tion is of still another species. The corollas are ncarh- two and a half inches 

 long, completely cylindrical ; the anthers extremely long-woolly, and the sterile 

 filaments pubescent at and toward the apex.
