come near two of Dr. Spruce’s species from the north-east of Peru, 
A, plumbicaule and A. fractiseriale. 
1678. Schizea digitata, var. orbicularis, Baker.—Barren fronds 
almost circular, the main divisions about four times dichotomously 
forked, so that we have from 100 to 150 final segments, which are 
wn to this many years ago by Mr. Whyte, of Medellin, who 
anki a photograph and numerous specimens. By its very dimorphic 
barren and fertile fronds, = the orbicular outline of the former, 
it looks very different in extreme form from typical digitata, 
but it is evidently seg ‘with the type by intermediate stages, 
as Fendler’s No. 485 from Venezuela, and Wright’s No. 926 
m Cuba.
