Shigeo Kurata
Nepenthes × ferrugineomarginata (; from Latin "ferrugineus" "rust coloured" and "marginatus" "margined") is a natural hybrid between "N. albomarginata" and "N. reinwardtiana". It has been recorded from the islands of Borneo and Sumatra. The type specimen was collected by Shigeo Kurata in Kenukat, West Kalimantan, in 1981. Kurata described the hybrid the following year. The name is a "nomen invalidum" as it was published without a Latin description.
