    Angiosperm lignins are constituted mainly of guaiacyl and syringyl units, with a minor proportion of p-hydroxyphenyl units. Thus, angiosperms, whose radiation came after divergence between angiosperms and gymnosperms, have always been considered as the Reproductive morphology of araucarian samara is revised revealing a carpellate structure of the stone. In A. columnaris it is formed by a supercoiled spermophyll (‘seed scale’), with a stigmatic apical lobe. This structure is analogous to the ‘classical’ peltate carpel of flowering plants. Stone opens with two apical pores. Pollen germinates on the apical stigmatic crest, with ?journalid=&paperId=
