    Default Paph hirsutissimum and Paph haynaldianum new orchid acquisitions

    These are my new paph acquisitions Paph hirsutissimum and Paph haynaldianum .
    The hirsutissimum flower measures 5in across, relatively large for the size of the plant.
    I had the choice between the haynaldianum and lowii and chose the former as the colour is better and the plant slightly smaller.

    P#1 & 2 - Paph hirsutissimum

    P#3 & 4 - Paph haynaldianum

    Hi Yew, very nice plants, great buying. Apart from that, #1 looks like P. esquirolei and #2 is definitely P. lowii, not haynaldianum.

    Thanks Roy for the ID, but I had always thought that Paph esquirolei was hirsutissimum var esquirolei.. Seeing that so many others have pointed out that what I was told by the vendor was a haynaldianum is actually a lowii I have to explain why I took his word for it. He pointed out that the haynaldinaum is darker coloured(marketing ploy) and that if we look from the front of the flower, the side-lobes on both sides of the staminode tend to stand out more prominently on the lowii than in the haynaldianum, which is quite close to the staminode and presents a slimmer appearance.
    However, now I know better .... it is a lowii then.

    Yew, the main feature between hayn' & lowii is that haynal' has a spotted dorsal, not multicolored like yours. there are other ID's but thats the best & quickest. The Paph is hirsutissimum var Esquirolei, just suggesting the variety.

    I was taught by an old- now long departed - and very distinguished Paph expert who ran a nurserey ( now run by his grandson) , in Paris, that with paphs, it is the rostellum which is very diagnostic. In a population there may be variation in colour and shape of the petals etc, but the rostellum remains invariable
    The rostellum - the shield-shaped structure in front of the pollinia , is concave, indented - in lowii, and with haynaldianum it is slightly convex.
    Which agrees - so far as diagnosis of the pic, with what is said above.

    As to P.esquirolei and hirsutissimum,the plants usually sold under these names are quite distinct, and one is much larger flowered than the other.
    However, Phil Cribb ( author of the Kew Monograph on Paphs) said that they were one and the same species ( although one was a sub-species) until he went and saw them in the wild. When he realised that the two populations never overlapped, and one was always at least 500 feet further up the mountain than the other, he changed his mind and made them two different species.
    Since then, I think I have heard, overlapping populations have been found elsewhere, and then there is a range of forms from one to the other - suggesting that he was nearer right the first time. But this is one of those things that it is possible to argue about until the world comes to an end. In fact as Phil Cribb himself said to me when there was an argument at a British Paph Society meeting - "the fact is, that the very concept of species, simply does not work very well with many orchids, especially paphs"
