A Twist
In article , Iris Cohen
writes OK, you guys, wake up. I have a question. Any orchid grower will tell you that hybrids between Sophronitis & other members of the cattleya alliance almost always have a quarter to half twist in the leaves. My experience in sewing leads me to speculate that they didn't fit the front of the leaf to the back properly. Does anybody have a botanically more correct explanation? Not that I think I can answer, but do you mean apical vs basal, or dorsal vs ventral? -- Stewart Robert Hinsley |

Iris, Central NY, Zone 5a, Sunset Zone 40 "If we see light at the end of the tunnel, It's the light of the oncoming train." Robert Lowell (1917-1977) I don't know either, but I've also seen it in my epiphronitis. Your speculation seems quite logical but why is another question. And why sophronitis? I haven't grown a pure sophronitis anything due to our hot climate, but with our recently upgraded cooling system I plan to soon. Please post if your searches turn up anything. |
