THE FERNS OF SOUTH AFRICA 
obliquely blunt pointed, or falcate, sometimes closely set 
and overlapping, and in others one line apart. In large 
fronds the pinnules are a quarter inch broad, three-quarter 
inch long, and the lower one on the upper side sometimes 
larger, and then pinnatifid. Sori small, placed on the veinlets 
halfway between the mid-rib and the margin of the pinnules, 
often many in a pinnule ; involucre small, fugacious, thus 
causing the confusion noted under D. obtusiloba. It differs 
from D. patens in having the lower pinnae reduced, and from 
D. mauritiana and D. mollis in the pinnae being cut to 
or below the lowest veinlets. Aspidium prolixum Willd., 
which is included in Burtt-Davy’s list of Transvaal plants, 
is presumably a large form of D. Bergiana , though Dry. 
prolixa (Willd.) O. Ktze, very closely related to D. Bergiana , 
is credited to Trop. Africa, Madagascar and India.
