Nephrolepis exaltata
Most of the
Nephrolepis
cultivars currently in cultivation derive from
Nephrolepis
cv.
'bostoniensis'
, which is
conventionally
associated with
N. exaltata
(
Benedict, 1916a
). An overview of the most frequently cultivated forms is given by
Hoshizaki
& Moran (2001)
.
Morton (1958)
suggested that
'bostoniensis'
was possibly a hybrid with
N. exaltata
as one parent. Its
constant
sterility, morphological instability and vegetative
vigour
indicate a hybrid origin, but there is no reason to assume that
N. exaltata
is involved as parent, when we consider that
N.
x
hippocrepicis
, which originated well outside the distribution area of
N. exaltata
,
exactly mimics the morphology of
N. exaltata
,
and another such hybrid may equally well have given rise to
'bostoniensis'
.
