Rhaphidophora guamensis
A climbing aroid endemic to Guam in the Mariana Islands, described by Peter Boyce in 2001. It is a moderately robust liana with a slender, much-branched stem and two distinct kinds of leaves (juvenile and adult), found in mixed forest, on limestone and even in coconut plantations. Grow it warm and humid with something to climb, as a lowland tropical climber.
Where it grows wild
Mixed forest, coconut plantations and limestone, climbing over karst rock and up trees. Herbarium collections come from the Almagosa Springs and Fena area in southern Guam, including a moist pit in pitted karst limestone, and from near the summit of Mt Lamlam. Young plants creep over limestone; mature stems climb into trees with larger leaves.
Guam's highest point, Mt Lamlam, is only about 406 m; one specimen from its summit area is labelled 400 m, and the others are from low hills in southern Guam, so it spans lowland to about 400 m.
