Re: [Aroid-l] Amydrium or Rhaphidophora

From: "Peter Boyce" <botanist at malesiana.com> on 2007.07.17 at 08:14:09(15985) Hi Helmut, The differences (leaving aside the generic ovary/ovule & fruit/seed differences) are: Epipremnum pinnatum Foliage leaves at more-or less one at each node. Leaves with pin-holes along the mid-rib. Shoot apex with matted fibrous material Stems with irregular longitudinal crests. Rhaphidophora decursiva Foliage leaves scattered and interspersed bu up to 7 nodes bearing only a cataphyll. Leaves without pin-holes along the mid-rib. Shoot apex without fibrous material. Stems without irregular longitudinal crests.

I have somme huge plants of this type in my greenhouse and the leaves are up to 6 ft (2 meters) long. My original plant is a huge climber - I think the only really big one in Europe - in the HBV (Vienna Botanical Garden). To my knowledge it always was presented there as Epipremnum pinnatum. In the history of the identification of E. pinnatum You find a lot of taxinom. changes. Can You, Peter, as the expert, bring clearness ? rgds.
