longis, pappi setis ca. 12 tenuibus albis 2.4 mm. longis ; flosculis 

 liguliferis ca. 40, ligulis angustis albis vel purpureo-tinctis tubo sub- 

 aequilongis apice saepissime bidentatis, achaeniis et pappi setis eis 

 flosculorum disci similibus. — Guatemala : growing on rocks in bottom 

 of canon, Fiscal, Guatemala, alt. 1130 m., 3 June, 1909, Charles C. 

 Beam, no. 6159 (type, in Gray Herb.). Tbis species is obviously of the 

 affinity of E. mucronatus DC, E. esrilis Gray, and E. Karwinskianus DC. 

 From the first of these it differs in having narrower (linear rather than 

 lanceolate) leaves, smaller heads, and relatively as well as absolutely 

 shorter rays (exceeding the disk scarcely by one third). E. exilis Gray 

 has the involucral bracts and peduncles very much more closely and 

 finely puberulent, and E. Karwinskianus DC. is described as having 

 the leaves glabrous on both surfaces.

 biaristatis. — Guatemala.: along railway, Fiscal, alt. 1130 m., 9 June, 

 1909, Charles C. Beam, no. 6250 (type, in Gray Herb.). This species 

 differs in its wingless stem and branches from such forms of V. turba- 

 censis HBK. as have unlobed leaves. From V. sublobata Benth., it 

 may be distinguished by its more bluntly toothed (crenate-serrate) 

 unlobed leaves which are more gradually narrowed to the winged 

 petiole.
