This species is also from New Caledonia in the northern part of the island. It is of similar height to C. nucele above and has the same trunk diameter. The crown shaft on C. elegans is slightly more swollen than that of C. nucele. The crown shaft is also more of a green color, but can show silver. The leaflets are thinner and, as you can see, the leaves curve downward as opposed to the stiff, upright leaves of nucele. Another important difference between the two is that the leaves of C. elegans are keeled whereas the leaves of nucele are more flat. You might have to look at these photos and then go above to compare with the Cyphophoenix nucele to recognize these differences. Of note, on both species the bare petiole (stem with no leaves) is very short. This helps you identify this genus. Mail order possible depending on weather.
Shown here is a 5g plant that I photographed recently. Also shown are garden specimens. This species should be started in filtered light and be allowed to grow into some sun if you live along the coast. Inland full sun is too harsh for this species. Cold hardiness is into the mid-twenties F.
