Munich, Germany.
Day Four. Today we went by tram to the Munich Botanical Garden (Botanischer Garten München-Nymphenburg).
We got there just about 10:00. It was crisp, but gloriously sunny ... a perfect winter day.
After lunch in their cafe we headed towards the big glasshouse. The glasshouse is divided into halls to cater for different environments and types of plant. Desert ... cacti ... bromeliads ... orchids ... ferns ... plants with medicinal or culinary uses. Brilliantly done.
Calibanus was a genus of two species of flowering plants in the family Asparagaceae, both evergreen succulents from dry areas of northeastern Mexico. The genus was subsumed in the genus Beaucarnea in the year 2014.
The APG III classification system places Beaucarnea in the family Asparagaceae, subfamily Nolinoideae (formerly the family Ruscaceae). The now-defunct Calibanus was formerly included in the Agavaceae (now Agavoideae) but was separated from them, for it is polycarpic and dioecious.
Its name refers to the monster Caliban, an antagonist in Shakespeare's The Tempest.
One of only two species in its genus, Calibanus hookeri is native to Tamaulipas in Mexico. It can can easily be mistaken in the wild for a boulder overgrown with grass tufts.
Calibanus hookeri forms a large caudex which has been known to reach diameters and heights of up to 2.6 feet. Atop the caudex sprouts narrow greyish-green leaves that look like grass. Each leaf rosette grown from the caudex is believed to be a vegetatively produced independent plant which dies after fruiting to be replaced by a new one. Branched flower stalks grow to 3 feet tall and bear tiny, greenish white flowers.
