Subtropical and Temperate zones. Through lowland South Amer- 

 ica south to Paraguay; ranges northward into Temperate North 

 America. 



Magdalena. Rio Buritaca (observed only in a swampy place, 

 bank of R. B., close to the sea — 50 m. e. of Santa Marta), H. H. 

 Smith 1329 (C, H, U, Y).

 Type species, S. pusilla Benth. 



1. Schistophragma pusilla Benth. 



Schistophragma pusilla Benth. in DC. Prod. 10; 392. 1846. "In Mexico 

 pr. Tehuantepec (Alaman!) ... (v. s. comm. a. cl. DC.)." De- 

 scription from a dwarf plant, which explains the variety following. 



Schistophragma pusilla major Benth., 1. c. 392. 1846. "In campis aridis 

 pr. Sta Martha fPurdie!) ... (v. in herb. Hook.)." 



Conobea pusilla (Benth.) B. & H., Gen. 2: 951. 1876. 



Open drj^, stony soil, at altitudes below 300 meters, Tropical 

 zone, in Magdalena, and doubtless spread across northern Colombia. 

 Ranges northward to Mexico. 



Magdalena. Bonda (alt. 60 m.), H. H. Smith 1970 (C, H, U, Y). 



["Rare on open, stony and dry ground, hillsides or banks below 

 1000 f."] 



17. MIMULUS Lmne. 

 Mimulus L., Sp. PI. 634. 1753. 

 Type species, M. ringens L., of Virginia. 



1. Mimulus glabratus H. B. K. 



Mimulus glabratus H. B. K., Nov. Gen. et Sp. 2: 370. 1818. "Crescit 

 prope Moran Mexicanorum, alt. 1330 hex. [ = 2527 m.]. Varies, even 

 in same colony, with leaves obviously petioled or nearly sessile, and 

 with all parts of the plant, including the flower, relatively large or rela- 

 tively small. The latter state is doubtless the basis of M. andicola H. 

 B. K. from Ecuador. 



Corolla lemon-yellow, within throat on anterior side golden and 

 spotted with many red-brown spots. 



Along streams, springheads, swales and brooks, at altitudes of 

 2300 to 3200 meters, Temperate zone, ascending as a dwarfed plant 

 to Paramo, and descending rarely into the Subtropical zone, both 

 slopes of Cordillera Oriental, in Cundinamarca. Doubtless through- 

 out this and the other Cordilleras. Ranges through the Andes 

 southward to Bolivia and with many breaks, through the mountains 

 of Central America and Mexico, northward to Colorado and the 

 plains of North Dakota.
