Eurrenabaque, 1,000 feet, M. Cardenas, October 6, 1921 {no. 

 808). 



var. ( ?) alba 



Stems slender. Leaves shorter and relatively broader, ab- 

 ruptly very short-acuminate at both ends, thin. Flowers white. 

 Bracts and fruit similar to those of the preceding, but smaller. 



Collected at the same time and place as the last, by the same 

 collector, who regarded them as distinct species. AVhether this 

 is a distinct species, or a mere variety of a polymorphous one, 

 is a question that must await further information. 



Ruellia serratitheca 



Subglabrous, the scattered whitish hairs short, minute, ap- 

 pressed, the stems quadrangular and sulcate. Petioles 1 to 2 cm. 

 long, slender, channeled, the bases of the younger ones con- 

 nected by an interpetiolar line. Blades 7 to 15 cm. long, 3 to 6 

 cm. broad, ovate, acuminate and acute, the base abruptly and 

 slightly produced into the petiole ; lightly and irregularly sinu- 

 ate-dentate, bright-green, thin, the slender venation prominent 

 beneath, the secondaries about 7 on a side, moderately ascending 

 and lightly curved and connected by numerous straightish ter- 

 tiaries. Panicles axillary, on very long and slender peduncles, 

 small, narrow and few-fiowered, the subconnate bracts linear, 

 elongated. Calyx 5 mm. long, the tube cupulate, very short, the 

 teeth linear-setaceous, subequal. Corolla bright-yellow, the 

 narrow cylindric tube a half longer than the calyx, abruptly in- 

 flexed above, the upper portion 2 cm. long, campanulate, slightly 

 contracted at the mouth, the lobes erect, very short, obtuse. 

 Lower portion of filaments connate in pairs, the anthers subex-
