Resumo: The morphology of 20 species of weeds that occur in the most common crops in Maringá, Paraná State, Brazil and adjacent regions were described at early developmental stages, in order to identify the species in the field and provide information for taxonomic and ecological works. Sixteen species featured epigeal-foliaceous seedlings. The seedling in Cardiospermum halicacabum is epigeal-fleshy; in Cenchrus echinatus and Digitaria horizontalis it is hypogeal and in Commelina virginica is epigeal-cryptocotyledonar. The differentiation of the first eophyll occurred within ten (Digitaria horizontalis) to 35 days (Bidens pilosa) and the first metaphyll appeared within 22 (Commelina virginica) to 49 days (Acanthospermum australe). The number of eophylls varied from one to four, and the phyllotaxis varied from alternate to opposite.

Em 16 espécies, a plântula é epígeo-foliácea. Em Cardiospermum halicacabum, é epígeo-carnosa; em Cenchrus echinatus e Digitaria horizontalis, é hipógea; e, em Commelina virginica, é criptocotiledonar-epígea (tipo “Durio”). A diferenciação do primeiro eofilo variou de dez (Digitaria horizontalis) a 35 dias (Bidens pilosa) e do primeiro metafilo de 22 (Commelina virginica) a 49 dias (Acanthospermum australe). O número de eofilos formados variou de um a quatro e a filotaxia, de alterna a oposta.Universidade Estadual De Maringá2007-12-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/47510.4025/actascibiolsci.v29i3.475Acta Scientiarum.
