Shoreline, Emergent and Aquatic Plant Species broadleaved arrow-head Sagittaria latifolia •Arrow-shaped leaves •White flower with 3 petals water-arum Calla palustris swamp beggar-ticks Bidens cernua http://www.missouriplants.com/Yellow opp/Bidens_cernua_page.html jewelweed (spotted touch-me-not) Impatiens capensis •Can help relieve itching (maybe from stinging nettle) •Bright orange spotted flowers water-shield Brasenia schreberi •Oval-shaped pads •Stem arises from middle of plant •No slits in leaf •Stem and leaf underside covered in thick slime sedge Carex spp. •Can look like Iris and/or Typha BUT!!!! •Triangular shape to leaf reed canary grass Phalaris arundinacea •Swollen nodes •Often times top seed stalk is at an angle from the rest of the plant http://images.google.com/imgres?imgurl=http://www.plantidentification.co.uk/images/gramineae/phalaris-arundinacea1.jpg&imgrefurl=http:// Eurasian watermilfoil Myriophyllum spicatum •Feathery look •Usually a red stem •Can form flower stalk like many other Potamogetons •Best way to tell this plant from Northern milfoil… when Eurasian is pulled out of the water it goes limp. When Northern milfoil is pulled out it holds it’s form. northern blue flag iris Iris versicolor •Leaves are folded at the midribs so they overlap each other •Smooth, sword-like leaves lesser duckweed Lemna minor •One of the smallest duckweeds •Has long hanging roots but smaller and shorter roots than other duckweeds •Used in many studies, including Dave Tillman’s ecology course purple loosestrife Lythrum salicaria •Very invasive •Looks a bit like fireweed, don’t get them confused white water lily Nymphaea odorata •Round floating-leaf with a slit •Round stem •White, showy and fragrant flowers smartweed Polygonum spp. pickerelweed Pontederia cordata •Emergent vegetation •Bright purple flower stalks pondweed Potamogeton spp. cattail Typha spp. willow Salix spp. http://www.cnr.vt.edu/dendro/dendrology/syllabus/factsheet.cfm?ID=86 speckled alder Alnus incana http://www.rook.org/earl/bwca/nature/shrubs/alnusincana.html
