We also currently grow well over 500 different clones of lycoris, which has formed the basis of our studies into the genus. In a nutshell, there are four names for hybrids of Lycoris radiata and one of the two orange/yellow species (L. aurea and L. chinensis). All F1 hybrids with fall-leaf species will have fall leaves, even crosses with a spring leaf species. L. x albiflora L. x elsiae L. x houdyshelii L. x straminea All of the DNA tests show that L. x elsiae is L. radiata x aurea Pretty much all of the DNA tests (except Shu) show that both L. x houdyshelii and L. x straminea are two names for the same cross of L. radiata x chinensis). L. x straminea is the earliest published name and would take precedent over L. x houdyshelii. Shu determined one parent to be L. longituba, with which we disagree. We grow several clones of each, many from controlled crosses, and the flowering times of all of the L. chinensis x radiata hybrids range from late July through mid-August, which makes sense since L. chinensis blooms much earlier than L. aurea. All of the L. x elsiae hybrids all flower in early September, coinciding perfectly with the flowering of L. aurea and L. radiata L. x albiflora is still a mystery. Most of the DNA tests show it to be L. radiata x aurea, while a few other show rather odd results (see below). We suspect these odd results occurred due to misidentified testing material. radiata v. pumila x aurea (Makino 1943) radiata var pumila x aurea (traubii)(Inariyama 1944) radiata var. pumila x aurea (Takuemura 1962) radiata var. pumila x aurea (Caldwell 1981) radiata var. radiata x traubii (Kurita 1987) radiata v. pumila x aurea (Furuta etal 1989) x rosea x chinensis (Lin 1990) (plants in the trade are not this parentage – ta) chinensis x sprengeri (Shi, Qui, Li, Wu, Fu 2006) (plants in the trade are not this parentage – ta) aurea (traubii) x sanguinea (Inariyama 1932,33,37) (plants in the trade are not this parentage – ta) If it turns out that L. aurea is one parent of L. x albiflora, then the name L. x albiflora would supersede L. x elsiae due to an earlier publication date. If the second parent turns out to be L. chinensis, the L. x albiflora name would become a synonym of the earlier published L. x straminea. The parentage of L. x caldwellii is also wrong. It is L. longituba x L. chinensis. We grow nearly a dozen clones of L. sprengeri x chinensis hybrids, and this isn’t one.
