  December  2018  IRG 108
 This bumper  issue of IRG, posted online a little early to celebrate the season,  contains descriptions of three new plant species. Janis Rukšāns discusses Crocus of series Kotschyani and describes a new species, Crocus hatayensis from Turkey, Janis Rukšāns and Henrik Zetterlund define a new Eranthis species from Iran, and John Watson dedicates a new Viola species to a very special person. 
We hope you find this an exciting way to conclude our ninth year of publication.

Corrigendum re IRG108 - Eranthis iranica
« Reply #121 on: December 29, 2018, 12:55:08 PM »
This note  about Eranthis iranica  has been received  from Janis Ruksans, Dr. biol. - and will be included in the next issue of IRG

   After publication of new species Eranthis iranica in December issue of International Rock Gardener (#108, 2018) I got two letters from Dirk Schnabel and Wim Boens - both of them noted that E. longistipitata (closest relative to E. iranica) seedlings have two seed leaves. Wim Boens wrote: “Nakai was the first to put longistipitata in the genus Shibateranthis in 1937. Later, in 1987, Tamura put it in the section Eranthis. And strangely enough Luferov put it again in the section Shibateranthis in 2004 (Turczaninowia 2004, 7(1) - in Russian - J.R.). In every case E. longistipitata and probably E. iranica are somehow the link between both sections. But maybe the sections should be redone completely.”

   When we placed E. iranica under Shibateranthis, we followed S. K . Czerepanov’s “Plantae Vasculares URSS” (Laningrad, Nauka, 1981) and other current botanical literature of former USSR, where genus Eranthis is listed only as synonym of Shibateranthis. We did not personally check seedlings of both aforementioned species. On page 3 ( page 4  of IRG 108)  of our article with caption “Eranthis longistipitata first year seedlings” most likely are pictured seedlings of E. pinnatifida. In 2013 the same picture was published in SRGC Forum by J.R. just as seedlings of E. pinnatifida. When few years later the same (?) pot bloomed, flowers were yellow and on long stalk, so name was changed on pot and on pictures. Most likely during replacing of nursery (which happened just in following years) when constructions of greenhouse were removed to new place and pots stood outside without any cover and protection or during transportation of pots to new garden some accidental misplacing of labels occurred.
   Wim Boens recently put E. longistipitata in Subgenus (or Series) Eranthis because most of the characteristics point towards that subgenus and only long pedicel join it with Subgenus Shibateranthis. Under such treatment all yellow blooming species are forming series Eranthis with 4 species (hyemalis, cilicica, iranica and longistipitata) and the rest - all with white flowers - go into Series Shibateranthis. In any case this does not invalidate the name of Eranthis iranica.
