218 BENEDICT: NEW VARIETIES OF NEPHROLEPIS 
The forms which are claimed as direct sports from var. bos- 
tontensis are as follows: Piersoni (PLATE 10, FIG. 2; PLATE II, 
FIG. 2), Schilleri, Anna Foster, Amerpohli (PLATE II, FIG. 7); 
Harrisi (PLATE 13, FIG. 3), Roosevelti (PLATE 13, FIG. 3), Scotti 
(PLATE 14, FIG. 2, 5), Schultheisi, Giatrasi (PLATE 15, FIG. 2) and 
Wittboldi. These forms do not represent ten diverse lines of vari- 
ation, but three, or at most four or five. Piersoni, Schilleri, 
Anna Foster, and Amerpohli show an increase in leaf division 
from the once-pinnate type of var. bostoniensis. Schillert seems 
to be an approximation of the form shown by Piersoni, which 
appeared more than ten years earlier. Both are twice-pinnate, 
as is Anna Foster, but the latter shows further differences in the 
shape and size of the ultimate segments, and other features. 
Amerpohli is thrice-pinnate, and, if directly descended from bos- 
toniensis, represents a skipping of the twice-pinnate stage. 
Scotti (PLATE 14, FIG. 2,5), Schultheisi, and Giatrasi (PLATE 15; 
FIG. 2) are dwarf sports of var. bostoniensis. Schultheisi seems to 
be an approximate repetition of Scotti, ten years afterward. 
Giatrasi is well distinguished from the other two dwarfs in char- 
acters of growth habits, leaf form, etc., so that there may be said 
to be at least two distinct kinds of dwarf sports. 
Harrisi and Roosevelti (see PLATE 1 3, FIG. 3) are almost 
exactly alike in respect to the leaf characters, but both differ from 
var. bostoniensis in having the pinnae more wavy or undulate, due to 
an increase in the parenchymatous part of the pinnae especially 
along the margin. Wittboldi, for which a spore origin is claimed, 
was originally described as “twice as wide as var. bostoniensis, and 
with wavy pinnae.” As yet I have no surely authentic plants, 
and so cannot speak with certainty. The original introducers do not 
have the plant in stock now, but the material at hand named Witt- 
boldi indicates that var. bostoniensis was probably not the parent 
form. The new form may have arisen as a chance sporeling, the 
result of the accidental introduction of some entirely different form, 
a very frequent occurrence in greenhouses. Herbarium specimens 
from Florida indicate that there may also be a “‘fish-tail’’ sport of 
var. bostoniensis, not included in the list of sports named above. 
There have probably been a few other variations of var. boston- 
iensts, either like those already named, or so unsatisfactory from 
the florists’ point of view that they have not been preserved.
