Herbarium
material
of Magnolia is usually incomplete
and inadequate for critical study. Collections
should include material of the stipules, spathaceous bracts, a full complement
of stamens, and all of the perianth segments to facilitate identification of Magnolia species.[1]

Studies of Magnolia acuminata have failed to reconcile the nature
of variation
in this widespread species. In an attempt to settle
differences in variation patterns, J.W. Hardin (1954) recognized
four infraspecific
taxa in M. acuminata. Later (1972, 1989) Hardin
abandoned his earlier views
for a more conservative stance, stating
that variation in M. acuminata lacked any consistent pattern
or geographic
correlation
. This is the view taken here--no infraspecific taxa are
accepted for M. acuminata at this time. Its flowers are normally
greenish and glaucous or sometimes yellow to orange-yellow, less
showy than those of other magnolias in the flora
. In southern areas,
trees with yellow to orange-yellow flowers (originally described
by Michaux as M. cordata ) occur in North Carolina, Georgia, Alabama,
and perhaps elsewhere, together with trees that bear normal greenish
flowers. Both filiform
and flagelliform trichomes
occur on the leaves;
cylindric
trichomes also occur. [source]
Magnolia acuminata is of value to horticulturists because no other
species of the genus has yellow tepals. Magnolia acuminata contains
major quantities of xanthophyll lutein-5,6-epoxide and, in smaller
amounts, acarotene-5,6-epoxide. Although this carotenoid occurs randomly
throughout populations of M. acuminata, often it is masked by chlorophyll
and not visibly expressed. Sometimes the carotenoid pigment
shows
through, as in the hybrid M. acuminata × M. denudata 'Elizabeth'.
In that cross
the M. acuminata parent tree was a nondescript
plant
with greenish flowers; yet out of this hybrid came 'Elizabeth', a
stunning plant with light canary yellow flowers, a result completely
unexpected. A thorough field
study of M. acuminata is clearly warranted,
and further investigation of the carotenoid flower pigments is needed
to clarify the taxonomy of this widespread tree. [source]
