Leaf Boundary Data of Phyllostachys incarnata T. H. Wen (Poaceae: Bambusoideae)

Description

The data consist of the boundary data of six leaves of P. incarnata sampled at Nanjing Forestry University campus in early December 2016.

Usage

data(bambooleaves)

Details

In the data set, there are three columns of variables: Code, x, and y. Code saves the codes of individual leaves; x saves the x coordinates of the leaf boundary in the Cartesian coordinate system (cm); and y saves the y coordinates of the leaf boundary in the Cartesian coordinate system (cm).
