" W. reticulata. Hook. f. (3), 231; Anderss. (1), 231, & (2), 99; 

 Rob. & Greenm. (1), 145. — This endemic species which has now been 

 found u[)OU no less than nine islands of the archipelago shows the same 

 sort of formal variation that has been described in the case of Eupliorhia 

 viminea, Hook. f. (see Rob. & Greenm. (1), 138-139). The original 

 characterization was unfortunately drawn from mixed material from 

 Chatham, James, and Albemarle islands. We may, however, take as 

 typical the form with a very close fine tomeutum, small thickish leaves, 

 1.5 to 2,0 cm. long, with strongly crisped margins. The leaves are 

 rounded rather than cordate at the base, and their indumentum becomes 

 decidedly yellowish in a dried state. This form, assumed as typical, has 

 been collected on Galapagos Ids. : Edmonston (lib. Gr.). Albe-
