Hornbeam

Hornbeams are relatively small hardwood trees in the genus Carpinus (Cár-pi-nus). Though some botanists grouped them with the hazels (Corylus) and hop-hornbeams (Ostrya) in a segregate family, Corylaceae, modern botanists place the hornbeams in the birch subfamily Coryloideae. The 30–40 species occur across much of the north temperate regions, with the greatest number of species in east Asia, particularly China. Only two species occur in Europe, and only one in eastern North America.

Wandlore
Hornbeam selects for its life mate the talented witch or wizard with a single, pure passion, which some might call obsession or&mdash;more kindly&mdash;vision, which will almost always be realised. Hornbeam wands adapt more quickly than almost any other to their owner’s style of magic, and will become so personalised, so quickly, that other people will find them extremely difficult to use even for the most simple of spells.

Hornbeam wands likewise absorb their owner’s code of honour, whatever that might be, and will refuse to perform acts - whether for good or ill - that do not tally with their master’s principles. A particularly fine-tuned and sentient wand.
