Sean Spence Posted October 11, 2004 Report Share Posted October 11, 2004 A friend has just had a Ping flower for the first time. It was purchased some time ago as P. leptoceras. Can anybody positively identify this plant? To me the flower looks a bit mutated, but I was hoping that there was enough there to ID it.

Sean Spence Posted October 12, 2004 Author Report Share Posted October 12, 2004 Any ideas or opinions? C'mon somebody must have a clue??? Quote Link to comment Share on other sites More sharing options...
pwilson Posted October 12, 2004 Report Share Posted October 12, 2004 It doesn't look right to me. Here is a link to a photo of P. leptocerus. http://encyclo.free.fr/images.jp4/cp12a.jpg I found this species in the Italian Alps this year and it apparently is always found growing with Pinus Mugo so it may prefer an acid soil, unless there is some other association with the mountain Pine.

byblis Posted October 14, 2004 Report Share Posted October 14, 2004 Hi Sean, it is not P. leptoceras. The flower is deformated but the leaves of P. leptoceras look quite different and remember more to P. vulgaris. The plant on the photo doesnot show that characteristics. Phil: P. leptoceras is definitely not always accompanied by pines, I have found plants by the thousands growing above 2000 m (6000 feet for you guys) in the Italian mountains. There was no pine, just a few larches and one alpine tree I donot know the Englisch name. Substrate was black, acidic soil and you are right that P. leptoceras is the acid growing Ping. of the alps, P. vulgaris is found on limestone ground.

pwilson Posted October 14, 2004 Report Share Posted October 14, 2004 Stefan, So it looks as if the association of P. leptocerus with the pines is purely due to the acidity of the local soil. Pine needles are of course, very acidic. I agree that P. vulgaris prefers alkaline soils. I have found it in the burren, in Ireland growing in alkaline bogs. I've also seen it in Scotland, growing not only on limestone rocks but also on pockets of mossy soil. I've no idea if these pockets of soil were acidic or alkaline. P. vulgaris has an incredible distribution. I've also seen it growing on limestone outcrops on the shore of Lake Huron. Phil Quote Link to comment Share on other sites More sharing options...
Sean Spence Posted October 14, 2004 Author Report Share Posted October 14, 2004 Thanks guys. Stefan, if it is not P. leptoceras do you have any idea what it could be? Quote Link to comment Share on other sites More sharing options...
epbb Posted October 26, 2004 Report Share Posted October 26, 2004 I think that this is P. grandiflora Quote Link to comment Share on other sites More sharing options...

Phil P.vulgaris is a reliable indicator or base-rich flushes, if you see it, you know that you are on a base-rich seepage. very useful for vegetation community mapping...

jeff 1 Posted March 9, 2005 Report Share Posted March 9, 2005 hello like ERIC I think it is a grandiflora sp grandiflora vulgaris is alcaline or acid like you want ; in france we found them in acid or alcalino-acid bog but also on the calcareous rock. for leptoceras in france ,italy ,switzerland we found them always on calcareous rock or alcalinoacid bog ( ph6) . jeff Quote Link to comment Share on other sites More sharing options...
byblis Posted March 10, 2005 Report Share Posted March 10, 2005 Jeff, you wrote for leptoceras in france ,italy ,switzerland we found them always on calcareous rock or alcalinoacid bog ( ph6) That is definitely impossible!!! P. leptoceras NEVER occurs on calcareous rocks but needs acid pH and calcareous FREE underground. This makes this lovely species grow only in the Central Alpes from France to Austria. Whatever you have found on calcareous rocks must have been P. vulgaris or P. grandiflora. Stefan Quote Link to comment Share on other sites More sharing options...
epbb Posted March 10, 2005 Report Share Posted March 10, 2005 Stefan, I have visited the Col of Tende location in France/Italy border of P. leptoceras indicated by J.Steiger and he had described it like this " It can be found on calcareous soil (Maritims alps in France) or in moist silicate soil elsewhere". I am convinced that everything is possible with our Pinguicula and I prefer being more open. Twelve years ago, I was speaking in Dionee, the french CP society about growing Pinguicula elsewhere than on peat mix and with gypsum or calcareous mix. Now it is stated that it is possible. P. corsica or P. lusitanica grow also very well on calcareous mix and so on despite growing naturally in free calcareous media. Quote Link to comment Share on other sites More sharing options...
jeff 1 Posted March 11, 2005 Report Share Posted March 11, 2005 no it is not impossible , the Ph is neutro alcalin or alcalino acid like you want ph 6 (ground constatation) , in the QUEYRAS ( 10 station) but also col de tende ,col de larche , col des bonettes, col de la cayolle ,col de vars ,etc ,etc . Stefan where have you make your constatation ? We make, with some friends, many constatation in the ground for all the PC the genus pinguicula is also my preference. leptoceras is caracteristic with his 3 inferiors lobs almost white. in these country I have never see grandiflora sp grandiflora , vulgaris perhaps or P.arvetii surely jeff excuse me for my bad english.

jeff 1 Posted March 11, 2005 Report Share Posted March 11, 2005 others monster (anomalie) it is also a grandiflora sp grandiflora or an hybrid ( longifolia sp longifolia x grandiflora sp grandiflora ) but a monster. excuse for the foggy picture. jeff Quote Link to comment Share on other sites More sharing options...
