Hi all,

	I recently purchased a plant labelled Thal. strecta which
turned out to be, to the best of my knowledge, one of the alligator
weeds (Alternanthera).  Are all species of Alternanthera only
semi-aquatic, or are there some true aqautic specimens?  Any good
books on identifying the different species?  TIA
