Floral Vascular System Anatomy of Heliconia rostrata ( Heliconiaceae )
金嘴蝎尾蕉花部维管束系统的解剖学研究

The floral vascular system of Heliconia rostrata Ruiz & Pavon were studied using paraffin section.Results showed that the carpellary dorsal bundles(cdbs) from the prolongation base were divided into two strands.A mixture of inner strands and placental bundles ran into the style.The two abaxial outer strands generated 2-4 branches and entered into the outer whorl at the two abaxial stamens,while the adaxial outer branch was the midrib of the staminode vasculature,which indicated its degenerate structure.Afte...
