It is odd that A. sessilis are shown as totally green with no trace of red. In my experience with the species, it was very dark red, much redder than the plant that S&KGray shows. My plant was unable to produce normal leaves underwater, just little scale-like structures, but as soon as the slow-growing stem broke the surface it produced normal aerial leaves. The leaves were purple-red, and the stem was so dark as to seem nearly black.
