Primula Rediscovered

Primula bracteata and Primula bullata are found in their type locations after 125 years.

Near Lhasa, Tibet

How do you tell the difference between P. tibetica and P. fasciculata?

Primula ambita in the Wild

The first ever cultivated plant caused a stir at Chelsea earlier this year.

New Primula Book

The latest Primula book is a revision of the 106 species of Primula found in India.

Recent New Primula Species (2016)

The New Year is a good time to reflect on what is new in Primula. Although I have made a lot of progress on my Original Description Project, the list of all Primula species is a moving target. In particular, there have been several Chinese species discovered. Changes for 2016 include:
Primula persimilis - from the original publication
Primula persimilis G.Hao, C.M.Hu & Y.Xu - Discovered near Luzhou, Sichuan, this species has white flowers with a tawny, hairy calyx. It belongs in Section Monocarpicae and strongly resembles P. tsiangii, but differs in flower color, capsule shape and length of pedicels and calyx.

Primula scopulicola G.Hao, C.M.Hu & Y.Xu - A new member of Section Monocarpicae from Sichuan growing at the same location as P. persimilis. It most closely resembles P. lithophila which also grows in the same area but has smaller flowers, distinctly petiolate leaves, a campanulate calyx, and the capsule is globose (not cylindrical).

Primula undulifolia G.Hao, C.M.Hu & Y.Xu - A new species from Hunan, named for the wavy and shallow undulations on the leaf margin. It is a member of section Carolinella which is noted for its calyptrate (opening by a lid) capsules and is similar to Primula kwangtungensis but differs by its smaller flowers and narrowly oblong leaves with an undulate margin.

Primula wawushanica G.Hao, C.M.Hu & Y.Xu - This species was listed in my 2015 year end post, but it had not then been officially published. It belongs in Section Petiolares, Subsection Davidii and resembles P. fagosa and P. epilosa but is distinguished by sessile leaves, smaller flowers, shorter scape at flowering and a calyx split to 1/3. See the original description for images.
Primula calderiana subsp. bawaii
Primula calderiana Balf.f. & R.E.Cooper subsp. bawaii Bawri, Gajurel & M.L.Khan - Differs from P. calderiana subsp. strumosa (P. strumosa) by having efarinose leaves, the calyx cut slightly deeper into lobes with an cute apex, and emarginated petal lobes. it is unclear how this subspecies differs from P. strumosa var. perlata or the yellow form of P. tsariensis.

There are also a series of newly described subspecies published in Primulaceen-Studien, which I don't currently have a copy of. They include:
Primula hirsuta All. subsp. brevipilosa Kress
Primula hirsuta All. subsp. longipilosa Kress

Primula intricata Gren. & Godr. subsp. alpina Kress
Primula intricata Gren. & Godr. subsp. bergidensis (Kress) Kress
Primula intricata Gren. & Godr. subsp. impigrorum (Kress) Kress
Primula intricata Gren. & Godr. subsp. patens (Kress) Kress
Primula intricata Gren. & Godr. subsp. subcordata (Kress) Kress

Happy New Year and Best Wishes to All in 2017!
