Native to slopes and forests of Japan and Taiwan, this small shrub has a common name of buttercup winterhazel. “Buttercup” refers to the colour of its flowers, while “winterhazel” intimates its belonging to the witchhazel family, the Hamamelidaceae. Here at UBC Botanical Garden, it reaches a height of roughly 2 meters while spreading out to nearly 3 meters. Like other members of the genus, the flowers are fragrant, but not overwhelmingly so.
When first beginning to bloom in late winter, it would be suitable to describe the plant as having a constellation of subtle yellow flowers; however, at full bloom, I'd perhaps describe it as a galaxy (specimen photographs). The somewhat misleading epithet, pauciflora (literally a paucity of flowers), makes more sense when comparing this species to other winterhazels. While buttercup winterhazel has clusters of two to five flowers, other members of the genus can have inflorescences of ten or more blossoms.
For a scientific description, see Corylopsis pauciflora in the Flora of China. The first draft of today's entry had an eerie resemblance to the gardening-centred article on Corylopsis pauciflora written by Paghat, since I don't recall reading her article before I'd written the first two paragraphs. I've restructured what I had written, but you can still see the similarities.

Dear Daniel Mosquin,
I recently signed up for your botany photo of the day and I just want to let you know how much I appreciate it. The photos are stunning; actually, yesterday's was a bit scary - I can see why it's called horridus!
Long live the internet!
Best wishes,
Sarah Dixon, in England (where we are currently experiencing what we think is extreme cold!)
Hi Sarah,
Thanks for the kind words - but I do need to say it isn't "my" botany photo of the day (I know what you mean, though).
BPotD wouldn't exist without the support and hard work of the other staff here at UBC (particularly the people who care for the plants), the non-UBC people who submit photographs and links and all of the readers and commenters like yourself.
These are so delicate and fine. I enjoy your pictures so very much.
That is a stunning picture Daniel
Flowers of Corylopsis prone to frost injury in exposed positions. Woodland conditions most favorable. There are some large specimens in David C. Lam Asian Garden at UBC.
I like to watch beautiful pictures on this site everyday.
Have you observed that the right side bunch of flowers look like a bird with the big water drop as eye of the bird.
Hi Daniel,
I am so glad I added this blog to My Yahoo!! Your pictures are so beautiful and your descriptions so very informative. I am learning a lot at the age of 60 ;-)!! Thanks so much. God bless.
I believe the paucity of flowers refers to their numbers on each inflorescence; i.e., few (2-5). Compare with C. spicata or sinensis, which have 10 or more per inflorescence.
