Hi Alan, This topic has been well covered by people from this forum and I have a supplementary view about the breaks in leaf colour found in most F1 Amarygias. There is little doubt in my mind about virus infection in the clumps of XAmarygia Parkerii in the Adelaide Botanical gardens labeled XAmarygia Parkerii. However having collected, bought and swapped F1 Amarygia bulbs from 9 different sources across 4 Australian states - it is clear that I have 3 cultivars that are totally free of the leaf colour breaks. The past two winter seasons have been very favourable (extra ground moisture) for XAmaygia growth and consequently all but 2 of the Amarygias in my collection show no sign of leaf color breaks this season, just clean even coloured bluish/ green leaves. Two cultivars with larger bulbs and wide ground hugging leaves are the only cultivars to retain and perhaps even more strongly express the light green (almost yellow) /darker green streaking of all the leaves. Five of the other seven xAmarygias are clear this season but in other seasons display small sections of disruption of the leaf colour light green/blue green. Having discussed this with a visiting botanist examining my garden bulb collection we came to the conclusion that in most F1 xAmarygias there was an incomplete expression of leaf colour in the cross between B. josephinea (glaucous leaf) x Amaryllis belladonna (light green leaf). This seems to be a reasonable conclusion as the leaf colour breaks are not found in cultivars of Amaryllis belladonna nor from the backcrossed cultivars of Amaryllis belladonna x F1 xAmarygia - but are found in almost all F1 xAmarygia's. Those cultivars showing yellow streaks covering most of the leaf surface are without question infected with a virus.
