Enclosing some pictures for identification. Is it Pegaeophyton spp ??
Location : Khardung La
Altitude : 5000 m
Date: 24 August 2014


Primula macrophylla (Primulaceae) to me.


This is not Pegaephyton scapiflorum.  Whilst this plant is recorded from Ladakh up to 5800m it belongs to the Brassicaceae (previously
Cruciferae) family which has rather different foliage and fruits.  This is a Primula belonging to the Primulaceae family. It is Primula meeboldii

I draw your attention to the unpublished research of Professor Arve Elvebakk, University of Tromso, Norway (Curator of Tromso Arctic-Alpine Botanic Garden). The PRIMULA MACROPHYLLA (sensu lato – meaning in the broad sense) COMPLEX has troubled botanists and specialist growers for more than a century. 

Elvebakk has recognised a separate taxon/species Primula meeboldii (honouring the German botanist who first collected pressed specimens of this on high passes in Ladakh in the 19th Century).  It has pinkish flowers and occurs in Ladakh and some other regions.  Hopefully the full details will be published in the not-too-distant future.

The images taken on the Khardung La are of Primula meeboldii at the early fruiting stage – the flowers have gone over, its capsules are developing. 

Anyhow, I am in support of the separation of P.meeboldii at species level, along with P.macrophylla sensu stricto (in the strict sense) and Primula moorcroftiana as separate species. 

I have found Primula macrophylla sensu stricto to vary a lot – so may well be subdivided at some point but the plant photographed in the VOF is not Primula moorcroftiana nor P.meeboldii nor matches the unknown(s) in Kashmir.
