× Renantanda, abbreviated Rntda. in the horticultural trade, is the nothogenus for intergeneric hybrids between the orchid genera Renanthera and Vanda (Ren. x V.). Its parent plants are both endangered, and have separate breeding seasons, so this hybrid is incredibly rare. Because of that, it is highly marketable.

Greges Rntda. Lily Aow = V. Pukele × Ren. Storiei – cultured by Boon Kee Aow, the orchid was named after Lee Lee Aow, his eldest daughter
