Investigations on a fossil agavaceous axis from Neyveli Lignite, Tamil Nadu, India

Abstract

Further anatomical observations on a fossil agavaceous axis from Neyveli lignite Mine-I, Neyveli, Tamil Nadu show the presence of anomalous secondary growth with amphivasal vascular bundles as well as other cell inclusions such as raphides. Simple perforation in the fossil vessel end plates suggests an advanced character of the plant. The Association of monosulcate reticulate pollen (cf. Liliacidites) in the same axis further supports its affinities with Liliaceae.
