D. "capillaris FL Long Arm." This pot has given me a number of headaches. Some plants in the pot are confirmed to be long arm capillaris, they have the pink flowers and produce viable seed, and have the characteristic semi-flattened lamina tip, but others at various times of the year (most notable during summer when leaves are longest) produce more rounded lamina and have never produced viable seed. I suspect them of being hybrids with intermedia. Ironic since it's thought this form may have arisen from a polyploid hybrid with capillaris and intermedia originally.
