although the name probably is not the most appropriate. Dr. En- 

 gelmann noted the flowers as " bright scarlet or crimson " ; the latter 

 seemino-ly is the more correct. Dr. Palmer describes the corolla of 

 his plant as "bronzy red, changing to bluish." The anther-cells at the 

 line of dehiscence are sparsely spinulose-ciliate in Palmer's specimens; 

 in those of Wislizenus, hardly at all so. 



Pentstemon fasciculatus. Fruticulosus, pedalis, glaber, P. 

 pinifolio, Greene, sat similis ; ramis fastigiatis foliosissimis ; foliis fili- 

 formibus seu acerosis rigidulis (circ. pollicaribus) oppositis confertis et 

 in axillis fasciculatis, floralibus subulato-setaceis ; racemo paucifloro, 

 pedunculis inferioribus nunc bifloris ; sepalis obovato-rotundis apicula- 

 tis ; corolla coccinea (|-pollicari) tubulosa sursum sensim ampliata vix 

 bilabiata, lobis 5 brevibus rotundato-ovatis subpatentlbus ; antherae 

 glabras loculis demum explanatis suborbiculatis filamentoque sterili 

 filiformi apice dilatato nudo e corolla baud exsertis. — At the Frailes, 

 half-way between Batopilas and the Cumbre, or mountain summit, 

 Palmer, 264. 



Pentstemon campanulatus, Willd. At Yerba Buena, north of 

 Batopilas, about 7,000 feet above sea-level. Palmer, 307. The most 

 northern habitat known. 



Stemodia Palmeri. Inter S. peduncularem et S. Joridlensem col- 

 locaiida, villosa, subviscosa, pedalis e radice annua ? ramis diffusis ; 

 foliis oppositis (nee ternis) membranaceis longius petiolatis ovatis 

 crenato- nunc duplicato-dentatis basi aut truncatis aut subcuneatis 

 (lamina 6-10 et petiolo 3-5 lin. longa) ; pedunculis solitariis geminisve 

 petiolo aequilongis ; sepalis lineari-attenuatis corolla (lin. 5 longa) vix 

 diraidio brevioribus ; stigmate bilamellato vix infundibuliformi ; pla- 

 centa post dehiscentiam apice bifido. — Shaded grounds, near Batopilas, 

 Palmer, 221, the corolla purple with yellow throat ; 250, with corolla 

 white. 



Seymeria virgata, Benth. Coll. Pringle, 647. Besides this, 

 which has by no means a virgate growth, Mr. Pringle collected speci- 

 mens (567) referable to S. pinnatisecta, Seemann ; and Palmer (325) 

 another form on the higher mountains above Batopilas. The pubes- 

 cence, foliage, and even the shape of the capsule, vary from specimen 

 to specimen. Probably all of them (even the Texan one with short 

 pedicels) belong to one polymorphous species. 



Lamourouxia cord at a, Cham. & Schlecht. in Linnaea, v. 103.* 



* This name is retained, under the impression that the species is not to be 

 merged in L. visrosn, HBK. Perhaps No. 703 of Ghiesbreght's Chiapas collec-
