In order for my students to work on live plant material, I have spent a lot of time in the greenhouses of the Botanical Garden and Botanical Museum Berlin-Dahlem to select appropriate study objects.

Tricky at first, but immensely helpful. As I become more familiar with Latex, I realize how efficient this markup language is for generating publication-quality diagrams and figures. For a commutative diagram displaying the transition rates of plant leaf shapes, the following Latex code suffices to generate a clear and succinct graph. \documentclass[]{standalone} \usepackage{tikz-cd} \begin{document} \tikzcdset{every […]

Among the specimens collected was also the white water lily (Nymphaea ampla DC.), an enigmatic species that grows throughout Mesoamerica and that seems to have […]

## Schematic of Plastid Genome in LaTeX

Professional graphics require code In order to visualize the location of oligonucleotide primers as well as structural rearrangements in plastid genomes, I wrote some Latex code. \documentclass[margin=10pt]{standalone} \usepackage{tikz} \begin{document} \begin{tikzpicture}[line cap=rect,line width=3pt] \draw[] (0,0) circle [radius=8cm]; % Draw small intervals, label small intervals \foreach \angle [count=\xi, evaluate=\xi as \xx using int(\xi*10)] in {157.5,135,…,-157.5,-180}{ \draw[line width=1.5pt] […]
