bode 
divergens Willd. (B!) and other specimens from the northern Andes, it seems rather 
different from . typica, with which it is, however, connected by intermediate forms 
referred to no. 2 and 4. Seldom it is quite without short, cylindrical, yellowish- 
brown, opaque tae on the larger veins beneath; the midribs of the secondary and 
tertiary pinnules are, as a rule, rather densely and softly pubescent with articulated, 
patent, thin hairs. The firm, mostly greyish-green lamina is less cut; the broad 
uncut centre of the secondary pinnules gives it a rather different habit from the 
more finely cut. — The var. confinis is an insular, reduced form of var. divergens. 
Below I enumerate only those specimens seen, which@are furnished with a 
collector’s number, sorting them under the five groups.
