Swartzia pinnata<\/em> stamens are dimorphic: many standing ones in front of a petal and two forwarded ones. Both stamens originate from the same primordium \uff08Tucker 2003). The former stamens function as feeding stamens for bubble bees and the lower ones function in pollination (Endress 1994). Pollen of feeding stamens are sterile and 2\/3 the size of fertile pollen. The decrease of the number of petals may be related to the increase of the stamen number.<\/p>\n

The genus Swartzia<\/em> contains ca. 140 species and is mainly distributed in South America and Africa. The number of petal is one or zero and the number of bigger stamens are different between lineages (Torke and Schaal 2008)\u3002<\/p>\n
