Stevia venosa. S. Plummerce, Gray, et S. scabrellce, Benth. sat 

 affinis, glabra, foliosa ; caulibus ut videtur omnino herbaceis ultra- 

 pedalibus ; foHis subsessilibus subcoriaceis (1-2-pollicaribus) fere in- 

 tegerrimis oblongo-lanceoUitis acutis tripli- vel tri-nerviis venosis, venis 

 prominulis adscendentibus laxe reticulatis modo S. Pbmimerce ; cymis 

 compactis fastigiatis ; pediceUis brevissimis ; involucro vix lin, 3 longo 

 stepius 4-floro parum viscidulo-puberulo, bracteis obtusis ; floribus 

 saturate purpureis ; pappo coroniformi brevi subcoviaceo margiue 

 eroso. — In a mountainous district, 150 miles north of Batopi- 

 las, November, Palmer, 376. Besides the entire leaves, tlie much 

 shorter and firmer pappus-crown distinguishes this from the Arizonian 

 S. Plummerce. 



Stevia Madrensis. Subpedalis, scabrido-puberula vel glabella; 

 ramis floridis subviscosis ; foliis omnibus oppositis lanceolatis sessilibus 

 membranaceis subtriplinerviis nervoso-venosis aut denticulatis aut fere 

 integerrimis ; capitulis laxe cymoso-fasciculatis subsessilibus ; involucri 

 bracteis (lin. 3 longis) obtusis ; floribus lilacini-purpureis ; acheniis 

 glabellis ; pappo coroniformi-concreto brevissimo. — Among Pines in 

 ravines on the summit of the mountains, at about 8,800 feet, 150 

 miles north of Batopilas, October, Palmer, 328. 



Stevia Palmeri. Bipedalis, undique etiam ad involucra pilis 

 brevibus patentibus mollibus pluriseptatis baud glandulosis subcanes- 

 cens ; foliis oppositis membranaceis subsessilibus obtusis, inferioribus 

 oblongo-spathulatis bipollicaribus parum triplinerviis obtuse serratis 

 basi cuneata integerrima, superioribus lanceolatis ; cymis floribundis 

 compositis ; capitulis brevi-pedicellatis ; involucri lin. 2 longi bracteis 

 membranaceis acutiusculis ; corolla alba, tubo brevi cum fauce lata 

 extus villoso ; acheniis glabris ; pappo tripaleaceo et biaristato. — 

 On the mountain-sides about 25 miles south of Batopilas, near the 

 hacienda San Jose, Palmer, 30. Certainly allied to ^S*. jicmiculata, 

 Lag., possibly a very pubescent form of it.

 Usque ad capitula crebra foliosissima, pube brevi canescens ; corollis 

 " flavido-albis." — In the mountains above Batopilas, at about 7,300 

 feet of elevation, October, Palmer, 251. 



Stevia laxiflora, DC. Hort. Monsp., &c. S. viscida, HBK. 

 Pine forest in the mountains, 150 miles north of Batopilas, Palmer,
