years' priority. Zahlbruckner has regarded it as a variety ftf 

 Centropogon ajfinis Mart. & Gal., a species of Guatemala and 

 southern Mexico with which our plant has little real affinity. 



^ Centropogon rubrovenosus n. sp. 



Stems climbing, strongly grooved and angh'd above, glabrous 

 or slightly verrucose below, minutely pilose near the nodes, the 

 internodes 2.5-5 cm. long; petioles stout, 6-8 mm. long, minutely 

 scabrous-pubescent; leaf-blades ovate, apparently rather fleshy, 

 6-7 cm. long, 3-4 cm. wide, broadest below the middle, gradually 

 narrowed or abruptly subacuminate to a blunt apex, broadly 

 rounded or subtruncate at the base, barely repand on the callous 

 margin and denticulate with minute, callous, appressed teeth 

 (2-3 teeth per cm. of margin, o.i mm. high), glabrous and dull 

 green above, minutely and sparsely pubescent on the mid\'ein 

 beneath, the surface pale green; lateral veins plane, 8-12 mm. 

 apart, arcuately ascending, the veinlets coarsely reticulate, the 

 veins bordered and the veinlets marked by bands of dark red; 

 inflorescence an elongate terminal raceme; peduncles slender, 

 2-3 cm. long, conspicuously pubescent at the base, sparsely pu- 

 bescent above, ebracteolate; bracts ovate, 5-9 mm. long, 

 petioled; hypanthium hemispheric, 3 mm. high, 7 mm. wide 

 when pressed, very sparsely and minutely pilose; sepals re- 

 flexed, linear, 7-9 mm. long, minutely pubescent, i-nerved; 

 corolla red, strongly curved, sparsely pubescent, the tube about 

 28 mm. long, the lobes broadly triangular-falcate, decur\'ed; 

 filaments exserted 10-12 mm., glabrous; anther-tube 6 mm. 

 long, glabrous below, the upper anthers pubescent w^ith purple 

 hairs at the tip, the two lower with a cartilaginous appendage. 



Type, Macbride 4104, collected 20 May to i June 1923, Hua- 

 cachi, near Muna, Peru, altitude about 6500 feet, and deposited 

 in the herbarium of the Field Museum of Natural History. 

 Closely related to C. yungasensis, from which it differs in its 

 elongate racemes and its ovate, red-veined leaves. 



^' Siphocampylus corynellus n. sp. 



Stem shrubby, thinly tomentose above, the internodes 5-15 

 mm. long; petioles 8 mm. long; leaf -blades thick and firm, nar- 

 rowly oblong-linear, 6-9 cm. long, 8-12 mm. wide, acute, finely 

 denticulate, long-cuneate to the base, dark-green, glabrous, and 

 strongly rugose above, densely white-tomentose beneath ; pe- 

 duncles axillary, 5-6 cm. long, erect; hypanthium broadly turbi- 

 nate, 6 mm. long, 9 mm. wide when pressed, faintly ribbed; 

 sepals erect, narrowly triangular, acute, separated by broad flat
