“…Colour code; blue, pollen; orange, androecial tube; purple, gynoecium; yellow, (underdeveloped or modified) stamens. As in many Caryophyllales, the nectary seems to be associated with the androecial floral parts (see for example Ronse Decraene & Smets 1991, Vanvinckenroye & Smets 1996, although an axial origin of the androecial tube and nectary cannot be ruled out (cf. Smets 1986, Smets & Cresens 1988; see also below.…”

“…Chasmogamous (flowers that open) and cleistogamous (flowers that remain closed) flowers may occur on the same plant and in the same cyme (Yurtseva 1998). Both types of flower share some common characteristics (Laubengayer 1937;Ronse Decraene and Akeroyd 1988;Ronse Decraene and Smets 1991;Yurtseva 1998). Stamens are arranged in two whorls and their number varies from 5 to 8.…”

Costea, M. and Tardif, F. J. 2005. The biology of Canadian weeds. 131. Polygonum aviculare L. Can. J. Plant Sci. 85: 481-506.A review and assessment of biological information as well as personal data are provided for Polygonum aviculare in Canada. The species has been revised taxonomically and the six subspecies that occur in Canada are presented. Three of the subspecies, P. aviculare subsp. aviculare, P. aviculare subsp. neglectum and P. aviculare subsp. depressum are weeds introduced to Canada from Europe. A fourth subspecies, P. aviculare subsp. buxiforme is apparently native to North America. The geographical distribution of the latter four subspecies is very wide. Plants exhibit a high phenotypic plasticity and genetic variability, and they easily adapt to a multitude of agrestal and ruderal habitats. The seeds have a variable dormancy and polymorphic germination as a result of heterocarpy, genetic and environmental factors. In other areas (Europe), the species has developed resistance to triazines. Plants are hosts to nematodes, viruses, and fungi that also affect cultivated plants. Costea, M. et Tardif, F. J. 2005. La biologie des mauvaises herbes au Canada. 131. Polygonum aviculare L. Can. J. Plant Sci. 85: 481-506. Le présent article brosse un tableau et évalue les données biologiques et quelques données personnelles sur Polygonum aviculare au Canada. La taxonomie de cette espèce a été révisée et les auteurs présentent les six sous-espèces acclimatées au Canada. Trois d'entre elles, à savoir P. aviculare ssp aviculare, P. aviculare ssp neglectum et P. aviculare ssp depressum ont été introduites d'Europe. Une quatrième, P. aviculare ssp buxiforme, est apparemment indigène à l'Amérique du Nord. Cette dernière se caractérise par une très vaste répartition géographique. Les plants montrent une grande plasticité du phénotype et une forte variabilité génétique, qui leur permettent de s'adapter aisément à une multitude de milieux agrestes et rudéraux. La dormance des graines varie et l'hétérocarpie, les paramètres génétiques ainsi que les facteurs environnementaux expliquent leur germination polymorphe. Ailleurs (Europe), l'espèce a acquis une résistance aux triazines. La plante sert d'hôte à des nématodes, à des virus et à des champignons qui s'attaquent aux espèces cultivées.

“…It is therefore possible that the similar tepal structure of Fagopyrum and OTvgonum represents a homoplasy, as both genera show important differences, such as tepal vasculature, nectaries, etc. (RonseDecraene & Smets, 1991).The general impression is that the tesselated tepal structure of the genus Pobgonella…”
