For the next week or so Daniel is away on holiday, so Eric La Fountaine and I will be looking after Botany Photo of the Day. I’m sure Daniel will be happy to share some photographs from his trip when he returns. In the meantime we have an image of Carpinus fangiana (synonym: Carpinus wilsoniana), or Fang’s hornbeam. Although unregistered, the tree in this photograph was given the cultivar name ‘Wharton’s Choice’. I took this photograph about a month ago after this smooth-barked, semi-weeping species caught my eye only a few steps from the Garden’s entrance. It stands out with its long, impressed-veined leaves and light-green, bracteate fruiting catkins. The male catkins grow up to 6cm, whereas the female catkins can be up to 50cm long (hence another common name, the monkeytail hornbeam).
Carpinus fangiana, of the Betulaceae, is a rare species native to central and western China. It grows on limestone hills in dense deciduous mixed forests with plenty of summer cloud cover and high rainfall. Carpinus fangiania has only recently been introduced into cultivation, and is now frequently planted as an ornamental. The plantings of this species here at the UBC Botanical Garden were only accessioned in 1986. The particular tree in the photo (as well as others here at the Garden) was grown from seed received from the Shanghai Botanical Garden that was wild collected in Hunan.
Fang Wen-Pei (1988-1983) lends his name to both the species’ epithet, fangiana, as well as the common name, Fang’s Hornbeam. Fang Wen-Pei was a Chinese botanist who collected over 20, 000 specimens, and described over 100 new species. He was well known for his work with the genera Acer and Rhododendron (see: Lancaster, R., Rix, M. 2011. 705. Carpinus fangiana. Curtis’s Botanical Magazine. 28(2):103-110).
