Peter Tristram 19/12/11 - I decided to take some pics of a plant Barry Genn recently (very) gave me. It is referred to as T. reichenbachii White (flowered form) and a lovely little beauty at that. As you can see there is some pigment in those petals. What struck me was the close resemblance to a plant from Burkhard Holm - plant obtained as seedling from T. streptocarpa White and probably a cross of White with the normal form. Once again, interesting pigmentation on close examination. A macro of the white streptocarpa from Lotte is also attached and this one is all white with a yellow corolla – there is variation in this group of Lotte’s collected plants.
Apart from how lovely these forms are, the name reichenbachii again confuses me. All of the plants I have seen and imported as either reichenbachii or tucumanensis (synonyms) are very small, only about 10-15cm in bloom whereas the descriptions refer to plants of 20cm or more with a dense rosette of polystichous leaves. Uwe Scharf has spent considerable time studying the complex including streptocarpa, arhiza, retrorsa, paleacea, duratii, graomogolensis and so on, both in the extensive European collections and in the wild. He makes interesting listening on this group, so I am going to ask if he has a summary he can help us with.
Chris Larson 20/12/11 - What I saw in the valley immediately to the north of Tucuman & most other places around NW Argentina was this smaller “reichenbachii” – the one we generally call reichenbachii here. Remember that Marj collected either 2 or 3 times in this area before she went there with me. I remember one locality in particular, probably somewhere near Salta or Jujuy, there was a location where there were heaps of what we call reichenbachii - and there were different coloured flowers at the same locality in dry scrubby forest, including the white one. Both Marj & I bought back a fair bit of the white one.
There is a form of “reichenbachii” that, I think, Cliff Norden used to sell at the BSA shows, which was quite a bit larger than the ones Marj & I collected, more like the 20cm plants of which you speak. Many nutters must have the descendants of Cliff’s seedlings – as well as Marj’s.
The strepto white from Holm can also be blue. I think that he may have been referring to foliage! It is certainly a chunky little white plant.
Bruce Dunstan 24/12/11 - My White streptocarpa flowered and it's white and purple as well.
Peter Tristram 24/12/11 - Hi Bruce. Was it from me? I have whites from 2 sources and only a couple of the Hromadnik ones are pure white, albeit with a yellow corolla.
