spiritus-sancti = the holy spirit. The origin of the name can only be assumed. The place of discovery is said to have been in the Brazilian state of Esperito Santo (portuguese for Holy Spirit), so it is reasonable to assume that Bunting has latinized the name here.
Philodendron spiritus-sancti is one of the rarest philodendrons, and is often referred to in English as the Holy Grail among philodendrons. The short stem with long, drooping leaves makes a brilliant looking houseplant, especially when grown in hanging baskets or hanging baskets. Please note: The pictures show young plants, adult plants have long, narrow leaves with clearly visible veining, and are deeply furrowed at the top.
