I have never grown D. pauciflora, but I have never heard of hybrids. I guess I will have to stay with the D. natalensis determination, but it feels wrong to me. I thought it might be similar to the Debbert species novae, but that seems close to D. trinervia.... I guess this will have to be one of the little mysteries from South Africa. Hmmmm, that sounds like a good cultivar name: Little Mystery :-) Thanks for the inspiration!
