Hi Alessandro, That is a dramatic image you sent! Thanks. Dark red soils like that were present in La Rioja and Salta Province, well to the south but I saw no bulbs there, only cacti. But northwest Argentina is a large place and it is quite possible to miss some sites. I also note that there is vegetative growth at the base with the plants in full bloom, which I did not see. And I never saw these bulbs appear in clumps. In spite of those features I was about ready to say that you have provided a good ID. However, without being able to see within the throat of the corolla I went back to the previous IBS page where I saw that H. aurea had stamens fully displayed and exserted. So, to get more info on Hieronymiella (not a genus I know much about!) I did an search at the Kew Catalogue of Life 2009. There, H. argentina is described as synonymous with H. marginata. Hoping to find an image I searched 'all Kew' and found an article by Alan Meerow (http://kew.org/science/tropamerica/…. htm ). In that article the genus is briefly referred to and, more important, there is an image of H. marginata. The image is nothing like either what I saw in the field or in the image you sent of 'H. argentinum' (must have slipped past the proof reader!). So, it seems that, with regard to H. argentina, either Kew is making a mistake or IBS is. It may be that the people who took that dramatic image, misidentified it. There is another species of the area, H. angustissimum, in the Kew list, but no image is provided. That name would at least be a good name for the species (very narrow), in reference to the flowers. I think we should look a little further, Alessandro. Maybe contacting Meerow, who does know something about these amaryllids. If there is someone on the list who knows him better than I, maybe they'd be willing. If not, I can give it a try.
