- even though some clades within the family apparently have lost several traits, Polygonaceae are monophyletic (Chase et al. 1993; Lledo et al. 1998; Cuenoud et al. 2002; Lamb-Frye and Kron 2003) with morphological synapomorphies such as aa sheathing stipule (ocrea), quincuncial aestivation, orthotro pous ovules, and achenes.

Our objective is to identify clades within Polygonaceae and to provide a global estimate of phylogenetic relationships in this morphologically diverse and geographically widespread group. We include a total of 75 species representing approximately 40 of the 55 named genera in the family.

Polygonaceae are widely distributed and most of the species are concentrated in the northern temperate region (Heywood, 1978). They are groups of morphologically different herbs, shrubs, small trees or climbers characterized by simple leaves with covering ochrear stipules, unilocular ovary and
Dec 30, 2011 · The Eriogonoideae were clearly distinguished based on a suite of morphological characters such as lack of ocrea, sympodial growth, and an involucre subtending the inflorescence; the Polygonoideae were distinguished based on presence of ocrea, monopodial growth, and lack of an involucre.
