Heterophragma Adenophyllum
''Heterophragma'' is a genus of two species of tree, constituting part of the plant family Bignoniaceae. The species are found in Southeast Asia and India. Naming and classification ''Heterophragma'' is part of the Palaeotropical Clade of the Bignoniaceae, closely related to the following genera: '' Catophractes'', '' Dolichandrone'', '' Fernandoa'', ''Kigelia'', ''Markhamia'', ''Newbouldia'', ''Radermachera'', '' Rhigozum'', ''Spathodea'', and ''Stereospermum''; and to the Coleeae clade (which contains '' Colea'', '' Phyllarthron'', '' Phylloctenium'', and '' Rhodocolea''). The Coleeae clade species are found in Madagascar and surrounding islands, whereas the other genera are found in Asia, Africa and Madagascar. The influential Swiss botanist, Augustin Pyramus de Candolle (1778-1841) named the genus in 1845, in his publication ''Prodromus Systematis Naturalis Regni Vegetabilis''. Description The trees, which can grow up to 20m tall, have whorled/verticillate arrangement o ...

Augustin Pyramus De Candolle
Augustin Pyramus (or Pyrame) de Candolle (, , ; 4 February 17789 September 1841) was a Swiss botanist. René Louiche Desfontaines launched de Candolle's botanical career by recommending him at a herbarium. Within a couple of years de Candolle had established a new genus, and he went on to document hundreds of plant families and create a new natural plant classification system. Although de Candolle's main focus was botany, he also contributed to related fields such as phytogeography, agronomy, paleontology, medical botany, and economic botany. De Candolle originated the idea of "Nature's war", which influenced Charles Darwin and the principle of natural selection. de Candolle recognized that multiple species may develop similar characteristics that did not appear in a common evolutionary ancestor; a phenomenon now known as convergent evolution. During his work with plants, de Candolle noticed that plant leaf movements follow a near-24-hour cycle in constant light, suggestin ...
