rather longer, and crossing the rachis obliquely. Fertile frond, or 
fertile pinnae, with the margin recurved so that the pinnules look 
rather narrower and more triangular. Veinlets free, mostly forked 
in the barren pinnules. Sori small, almost marginal ; indusium 
small, deciduous, ciliated, glandular. 
Var. / 3 . squamuligerum (Schl.) has the mid-rib of the pinnae 
scaly with short, wide, whitish scales, and to it all the South 
African specimens I have seen belong. Kuhn credits this variety 
to South Africa and New Zealand only. 
N. Thelypteris has a different habit of growth from most of the 
other Nephrodiums, for owing to its long slender underground 
rhizomes it takes possession where it gets a hold, and forms a mass 
of fronds several yards wide. N. unitum which often grows inter- 
mingled with it also has this habit.
