Abstract
The study of wood anatomy of 6 species of Lycium L. was made. These species share an homogeneous structure. The essential wood characteristics are: dendritic distribution, presence of spiral thickness in the secondary wall of vascular elements and tracheids, apotracheal and paratracheal axial parenchyma, radial heterogeneous, and libriform fibres. The presence of fibriform vessel elements is described in 6 six species of Lycium for the first time.
Highlights
This paper is a further contribution to a series describing the wood anatomy of Lycium indigenous to Argentina (Norverto, 1988; 1989)
In the present study fibriform vessel elements were found for the first time in the Solanaceae. 1,ycium h a s fibrirorm vessel elements of fusiform shape, the tips of witch extend well beyond perforation plates
