Abstract
The floral anatomy ofSwietenia mahogoni Jacq.,Soymida febrifuga Juss.,Chukrassia valutino A. Juss.,Dysoxylum binectariferum Hook.,Aphanamixis rohituka W. & A. andHeynea trijuga Roxb. are discussed. Calyx is supplied by two whorls of traces inSwietenia, Aphanamixis, Chukrassia andHeynea and only one whorl of traces inSoymida andDysoxylum. In all the species, exceptHeynea, petals receive their supply independently. InHeynea petals receive their supply from compound strands. Staminal tube receives its supply from compound strands inSwietenia,Chukrassia, Heynea, Aphanamixis and from independent strands inSoymida andDysoxylum. Anthers are syngenesious inDysoxylum.
Ovary is supplied only by carpellary ventrals inSoymida, carpellary ventrale and ovary wall traces inSwietenia, carpellary ventrals, ovary wall traces and carpellary dorsals inChukrassia and carpellary ventrals, ovary wall traces, carpellary dorsals and secondary marginals inAphanamixis, Dysoxylum andHeynea. Disc is considered receptacular. Ovary is 2–5 locular at the base but becomes unilocular above. InChukrassia it remains tetralocular throughout. Ovules show attachment to axile placentae inChukrassia, Heynea andAphanamixis and to parietal placentae inHeynea,Soymida, Dysoxylum andSwietenia. Non-vascular, 8–20 teeth-like structures are formed from staminal tube. These are interpreted as fused or interpetiolar stipules.
