Part 141 - Primula observations and hybrids near Karponang and Sergong La

1 page

SUMMARY:
Notes on Primulas from Karponang grown at 4500', highlighting unusual rose coloration, leaf variation, and difficulty matching key characters; possible identification as elongata is questioned. Field observations report local abundance up to about 8500' near Sergong La, and above 12500' white forms of P. calderiana and natural hybrids become more common than the deep violet true P. calderiana.

Primulas from Karponang in our garden at 4500' have grown leaves like bracteosa. Due to low altitude?
Never seen the rich rose colour before.

Locally quite common.

Eventually found very common, highest altitude about 8500' near Sergong La.

This does not answer the key 'tube 3 times as long as calyx'. It is nothing like it.

Might be elongata, but leaves are pretty rotund.

Not common.
This seemed to be the same as 18946, but leaf varies. Probably both are the same thing.

A gathering with very few old capsules even some old seed.
These three are all natural hybrids. As one gets above 12500', so white forms of P. Calderiana become more & more common until at 13000 & a little above - just at the top edge of the abies zone - these hybrids become much more common than the true P. Calderiana, which here is deep violet. What are the parents?
P.T.O.
