of cafion, Fiscal, Guatemala, alt. 1130 m., 3 June, 1909, Charles C. 
Deam, no. 6159 (type, in Gray Herb.). This species is obviously of the 
affinity of H. mucronatus DC., E. exilis Gray, and E. Karwinskianus DO. 
From the first of these it differs in having narrower (linear rather than 
lanceolate) leaves, smaller head, and relatively as well as absolutely 
shorter rays (exceeding the disk scarcely by one third). . ewilis Gray 
has the involucral bracts and peduncles very much more closely and 
finely puberulent, and H. Karwinskianus DC. is described as having 
the leaves glabrous on both surfaces. 
Verbesina medullosa, n. sp., frutescens 1.21.8 m. alta; cauli-

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