fronds brown at first then turning green	frond about as long as broad

flowers large, 2-4 cm wide	large, heart-shaped leaves

green flowers	Thalictrum-shaped leaves, stems with a glaucous (waxy) bloom

readily identifiable	a winter annual typically in dense populations

bark shaggy; typically a small understory tree in wet forests	branched thorns; simple thorns on younger twigs and trunks	leaves variable

flower lobes not as flared as D. cucullaria	leaves are indistinguishable from D. cucullaria

white flowers	leaves indistinguishable from E. americanum

in fruit showing two large single-seeded nutlets. Note tiny petal above top nutlet	in full bloom: a species that pleases everyone	typically found in very dense populations

whorled linear leaves, variable in number at a node, strigose hairs are evident	it clings to t-shirts	it clings to dogs	a winter annual: overwintering rosette (above), flower and developing fruit (below)

a common lawn and agricultural weed	zygomorphic flowers, stems square

five-lobed corolla tube	flower color varies from white to lavender to purple to blue

very distinctive peltate leaf	flower positioned below leaves; note fertile ramets have a pair of leaves	emerging fertile ramet rams its way through leaf litter (4/4/04)

spreading canopy is characteristic	often very large with rough, deeply and irregularly furrowed bark		note large terminal lobe

a common weed in open ground and in open-canopied forests	note compound leaves on stem and simple leaves at base	flower is much reduced relative to other members of this genus

Shiny, large flowers (1.5-2.0cm wide)	leaves compound, stems trailing, inhabits swamps

very rough, gray bark		typically clonal, so trunks are often clumped

round stems stems with prickles	stems with glaucous (waxy) bloom	leaves are "two-toned" left: top surface, right: leaf bottom

leaves petioled, sepals recurved down stem	compare this species with the species to the left in this picture	two more views

this is another stemmed species

yet another stemmed species	compare shape of flower with V. sororia so you don't confuse this species with a white-flowered individual
