Welcome (back).

It has been a while since the last update. In that time I've been working on the genus Cypripedium. I know the current list on the website is not perfect, but I think it is a descently usable list.
Further more new names have been added, including the lasted published hybrids (excluding the genus Paphiopedilum). The vast list of Paphiopedilum hybrids is still a work in progress.

Species' influence charts.

Species' influence chart example.
With the revision of this website that was uploaded on 08-Feb-2018 came a new feature. On the Ancestry tab of the data page of every hybrid, a pie chart has been added that shows the percentage of influence of the species involved in the creation of the hybrid.
