Some references say three, some four. probably depending on whether
certain populations are considered distinct. i don't think you can go
completely on stature, distribution, or habitat in judging whether a
population is different. So, those high elevation forms that grow tall
may be specifically the same as lower elevation forms that don't grow
so tall. one species, called "narrow leaved cattail" generally has
leaves only about a half inch wide. Another, simply called cattail,
has leaves more like one to two inches wide. Both are widely
distributed. finally, in the sw, there are 'tules" (pronounced tuleys)
with very long inflorescences, more than half the length of the
flowering stem. These may grow further east, also, i don't know. lots
of cattails in oklahoma grow over ten feet tall, at low elevations.
