\section{Short answers (42 or even more points)}
\be
\item Mycoparasitic, achlorophyllous plant \emph{Lacandonia schismatica} (below) grows in the rain forests of Mexico. It is called ``\emph{schismatica}'' (i.e. heretical) because its flowers have pistils placed outside of stamens, and stamens---in the center of flower. How could this placement be favorable for the plant? (\emph{plausible explanation $=10$ points})

\vspace{\stretch{1}}
\item Please describe what could be a plant ``located'' at the point \textbf{A} in the morphospace of life forms below. How might this plant look? If you have an example in mind, please list it here. (\emph{plausible explanation with example $= 10$ points, without example $= 5$ points})
