More variation:
Look at these interesting petal differences. None have notches in the tips, but
the petal outlines are different (even allowing for crisping due to age). Look at the colors, too! The ones at
lower right are very pale (including the fresh one just visible in the lower right corner),
while the ones at top right are yellow (and one is yellow mostly along the petal center); meanwhile the one at top left has
pinkish highlights.
I have seen
Sarracenia alata with pink highlights in the petals in Mississippi,
but those plants are arguably explained as being genetically infiltrated by hybridization
with S. psittacina. But the Texan plants shown above occur at a site with no other
Sarracenia species...
