Euphorbia panchganiensis Blatt. & McCann: One of the endemic Euphorbia i.e Euphorbia panchganiensis Blatt. & McCann
From Kass Plateau in the month of May (01/05/2009)
I have always confusion in between Euphorbia panchganiensis and E. glauca Roxb.
But I think Bot are different.
Little herb with tiny flowers in sunny days on barren plateau its interesting……………… 

Nice plant and photographs. I was just reading about this species while sorting my specimens of Euphorbia.

Very nice, and that’s dedication!



EUPHORBIACEAE FORTNIGHT: Euphorbia panchganiensis Blatt. & McCann from Kass (Maharashtra) : Attachments (2). 2 posts by 2 authors.

Please find one of the endemic Euphorbia. E. panchganiensis Blatt. & McCann.
Picture was taken during 2010, in the dry days of April on Kass Plateau. I just willing to know is it different from Euphorbia acaulis? 

It is a synonym of Euphorbia nana.

Ex situ conservation at Botanical Survey of India, Pune.

if it is what i think it is, it should form a beautiful caudex.
does it//did it

Thanks to the people conserving it.
The earlier name was Euphorbia panchganiensis Blatt. & Mc Cann synonymysed with it now.
Mentioned in Red Data Book of Indian Plants Vol-3:122-123 as rare.
Earlier known from Maharashtra as E.panchganiensis but now known from Western Himalaya too.
Thanks for showing this rare species Sir!
I never saw it in Uttarakhand during last two and a half decade.

I knew it as a Euphorbia panchganiensis
so i had googled it middle of the nite and was surprised to see name nana
what makes people change an obviously indian origin name to a nondescript name like nana
this is what i dont understand 

It is restoration of correct name rather than intentional name changing.
This plant was first described by Royle in 1836. Later Blatter and Mc Cann also described the same plant (obviously collected from Maharashtra) in 1931 without knowing that it is already described.
ICN (International Code of Nomenclature for Algae, Fungi and Plants) simply says that earliest legitimate name will only be the correct name so that due credit is given to the author describing the species first.
The case remained unnoticed but now sorted out; credit now to Royle who introduced this plant to science first..
The epithet “nana” indicate small nature of plant.
Botanists (particularly Taxonomists) have a large set of rules (ICN) for naming plants and they follow it. Some of them keep searching history of names and correcting them throughout their research career.

thank you …

that explains the frequent name changes

i have seen botanists at some renowned bot gs some of whom did only do just that spend their office time in tracking the order of discoveries

drove me bonkers, they could have gone on to learn the newer fields  of study and analysis…
but it looked like inertia at worst or obsession at best
or fear of newer avenues to do investigation with.. such as molecular biology

Sometimes back a senior scientist commented in a reputed Indian journal that he feels pity for the taxonomists who keep on digging and searching old literature in search of correct name of a plant which is a wastage of time!

Because of such thoughts and comments we are lagging far behind in this field.
