Polygonaceae
The Polygonaceae are a family of flowering plants known informally as the knotweed family or smartweed—buckwheat family in the United States. The name is based on the genus ''Polygonum'', and was first used by Antoine Laurent de Jussieu in 1789 in his book, ''Genera Plantarum''.Antoine Laurent de Jussieu. 1789. ''Genera plantarum: secundum ordines naturales disposita, juxta methodum in Horto regio parisiensi exaratam''. page 82. Herrisant and Barrois: Paris, France. (see ''External links'' below) The name may refer to the many swollen nodes the stems of some species have, being derived from Greek, ''poly'' meaning 'many' and ''gony'' meaning 'knee' or 'joint'. Alternatively, it may have a different derivation, meaning 'many seeds'. The Polygonaceae comprise about 1200 speciesDavid J. Mabberley. 2008. ''Mabberley's Plant-Book'' third edition (2008).

Simple Leaves
A leaf ( : leaves) is any of the principal appendages of a vascular plant stem, usually borne laterally aboveground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the shoot system. In most leaves, the primary photosynthetic tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf but in some species, including the mature foliage of ''Eucalyptus'', palisade mesophyll is present on both sides and the leaves are said to be isobilateral. Most leaves are flattened and have distinct upper (adaxial) and lower (abaxial) surfaces that differ in color, hairiness, the number of stomata (pores that intake and output gases), the amount and structure of epicuticular wax and other features. Leaves are mostly green in color due to the presence of a compound called chlorophyll that is essential for photosynthesis as it absorbs light en ...
