===Taxonomic Status:=== ''C. rumphiana'' is a widespread sp. in parts of Indonesia and New Guinea to the Solomons. Without having New Guinean material for comparison but having seen photographs of ''var. papuana'' Becc. it seems possible that the populations each side of Torres Strait are not distinctly different. Future research into this sp. will probably reduce the number of trinomials. It should be mentioned that a large percentage of the Cape York Peninsula flora is actually Papuan and of recent establishment. ''C. rumphiana'' var. ''australiasica'' performs exceedingly well under cultivation in the tropics and is one of the fastest growing palms I have ever tried. One can expect the seed to germinate within two months of sowing and the seedlings can be planted out in one year by which time they are about 1. 5 - 2m tall and have bipinnate leaves. The tree also grows rapidly, which is unfortunate as it dies after flowering, a process which lasts for two years and begins in 6-8 years after planting out, probably less in the wild. However in subtropical areas the plants should be somewhat slower in all respects. Light shade is desirable for juveniles but adults can take full sun. Unfortunately the leaves are easily damaged by wind so a sheltered site is preferable. The plant is more attractive than ''C. urens'', having flatter, broader leaves with more regularly inserted leaf rachillae. Good soil nutrition and regular watering are needed to prevent the leaves from becoming yellowish in full sun situations. The leaves, although larger than ''C. mitis'' present no problem with disposal, likewise the trunk which is less bulby than ''C. urens''. As I know of a specimen of ''C. rumphiana'' (from Iron Range) that is thriving in Atherton, a rather cold place, I feel it should accommodate itself easily to southern Queensland. <div class="row"> <div class="small-0 large-6 columns"> [[File:Caryota_rumphiana2-01.jpg|frame|]] </div> <div class="small-0 large-6 columns"> [[File:Caryota_rumphiana3-01.jpg|frame|]] </div> </div> Figure 1.
