It is a flat, typically 1/4"-1/3" leaf with veining running parallel to the leaf edge. Dwarf Sagittaria is a rosette type stemless plant and will form dense clusters if not thinned. It is native to South America and Eastern North America. To propagate Dwarf Sagittaria, clip individual plantlets from the runner when the roots are approximately 1 inch or larger. It is very similar in appearance to Echinodorus tenellus, however Dwarf sagittaria can be identified by the "broken glass" appearance on the leaves, where Echinodorus tenellus doesnt. It can be seen in the first and second picture links below. http://i57.photobucket.com/albums/g221/lbwhiteboy/cpleco1.jpg "Broken Glass" appearance of Dwarf Sagittaria http://www.aquapage.cz/Obrazky/Rostliny/Sagittaria_subulata.jpg Not mine, but a great picture which shows the plants profile and also the "broken glass" appearance. http://i57.photobucket.com/albums/g221/lbwhiteboy/redsag.jpg A floating Dwarf Sagittaria plant that has been floating and has tuned pink under the intense lighting. http://i57.photobucket.com/albums/g221/lbwhiteboy/Sags.jpg A pretty thick mat of Dwarf Sagittaria I grew. http://www.aquapage.cz/Obrazky/Rostliny/3083.jpg Another photo that isnt mine, but a great shot of a Dwarf Sagittaria flower.
