O.fimbriata (O.erubescens?)

Post by Marko.D on Fri Sep 28, 2012 6:02 pm

Orostachys fimbriata (Turcz.) A.Berger ,Nat. Pflanzenfam., ed. 2[Engler & Prantl] xviii a. 464 (1930)

is sometimes called O.fimbriatus (Turcz.) Berger
(not sure what's correct).

Species occurs in Russia, China, Tibet, Mongolia and probably North Korea.
DISTRIBUTION MAP: http://geoserver.ioz.ac.cn/map.html?s=4&level4=CHS-ZJ,CHI-NX,CHN-HB,CHN-GS,CHM-HJ,CHI-NM,CHS-AH,CHN-SA,CHM-LN,CHN-SX,CHQ-OO,CHS-JS,CHC-HU,CHS-HE,CHN-SD&seas=
(you might have to wait few sec's until map loads).
It's often cultivated in South Korea and Japan.

names in other languages:
China: 瓦松 wa song (more local names on the link below)
Russia: Горноколосник бахромчатый

If you ask me, this species looks very similar to O.japonica. Sometimes it's very hard to
distinguish this 2 species. If you look O.japonica from Tsushima island you
would probably think that it's O.fimbriatus. Of course, every botanist would say now that
I have to look at flower morphology, distribution etc.

Also, in culture there are plants called O. erubescens. Mr. Eggli in Illustrated handbook of succulent plants
treat Orostachys erubescens (Maxim.) Ohwi (1942) as a synonym of O.spinosa, and also
Orostachys erubescens var. japonica (Maximowicz) Ohwi (1953) and
Orostachys erubescens var. polycephala (Makino) Ohwi (1953) as synonyms of O.japonica.
Many sources suggest that species O. erubescens should exist. I only wonder what is it?
My plants labeled as O.erubescens look very much like O.fimbriata. I wonder if my plants are wrongly labeled or
O.erubescens is a synonym of O. fmbriata? Could someone please explain this mess with names?

Pics that should make my post more complete:

O. fimbriatus from Soochow, China


O. fimbriata var. limuloides (this pic is a few months old now, sorry didn't had new pic)
This name is not valid anymore but I like to keep original names of my plants. Also all O.f. limuloides in culture are very
distinctive plants.


Flower stalks from plants above photographed last fall.


This one came labeled as O.erubescens. Looks almost the same as O. fimbriatus ex Soochow. (???)


O.erubescens, light form. (also ?)



As you might have noticed I sometimes write O.fimbriata and sometimes
O.fimbriatus. It's also because I write original labels.

Quite ''unexpected'', most of my plants are labeled wrong. They are all in fact different forms of O.japonica.
It's confirmed for all of them except for the plant labeled as O. fimbriata from Soochow, China.
It wasn't my research so it would be impolite to write more. Our forum member did this research so I hope one day he will find some time to write more. 
Regardless to the name they look really impressive at this time of year
