DESCRIPTIONS OF THE SPECIES 
185 
Var. KREBSII (Kze) Sim. 
Plate 81. Nat. size, b Fertile part, magnified. 
Fertile frond similar to the barren, both with pinnae three 
inches long, four lines broad, more or less crenate, with a 
wider cordate base, or auricled on one or both sides. Sori 
halfway between the mid-rib and the edge, attached to the 
veins, the two from different veins meeting face to face, as 
in Scolopendrium, and when mature forming one rounded, 
or oval, oblique sorus. Wood remarks — “An examination of 
some of the immature fronds will show that while the whole 
of the sori near the base of the frond are at an acute angle 
with the rachis, at the apex they become almost parallel with 
it, and are single and not double as at the base. Different 
forms are found, at last completely merging in true pimctu- 
lataP Wood also mentions a bi-pinnate or bi-pinnatifid form. 
In a letter dated Apr. 8, 1913, Dr Wood writes: 
“ I wish to renew my opinion, published more than 30 years ago, that 
Scolopendrium should stand as originally named, and not as a variety of 
Lomaria punciulata. I am still of the opinion that the varieties con- 
necting var. Krebsii with the Lomaria are dying out, and am confirmed 
in that opinion from recent collections in Natal.’ 5 
We have had no opportunity of studying this plant alive, 
but understand Prof. Bower of Glasgow University is looking 
into the matter and has been supplied with living plants by 
Dr Wood.
