resistant to pollution
Gingkophytes The single surviving species of the gingkophytes group is the Gingko biloba Figure 26.11 . Its fan-shaped leavesunique among seed plants because they feature a dichotomous venation patternturn yellow in autumn and fall from the tree. For centuries, G. biloba was cultivated by Chinese Buddhist monks in monasteries, which ensured its preservation. It is planted in public spaces because it is unusually resistant to pollution. Male and female organs are produced on separate plants. Typically, gardeners plant only male trees because the seeds produced by the female plant have an off-putting smell of rancid butter.
