The name is attributed to Desfontaines (1829), who had published
it as a nomen nudum based on material annotated by Gaudichaud-Beaupré
and held in P. This specimen (above) is clearly of an immature leaf of
C. circinalis from plants of unknown origin cultivated
The name must therefore fall into the synonymy of
Although described very early in the history of the genus, this
name has been poorly understood throughout its history. It was
formally named in 1829 by French explorer and botanist C. Gaudichaud-Beaupre
(1829), in his treatment of the botany in M.L. de Freycinet's account
of voyage of the ---- (Gaudichaud
1829). He ascribed the name to Renee Louiche Desfontaines().
Desfontaines had published it (without a description) earlier in 1829
in a listing of plants in the king's collection, although he in
turn had taken the name from a herbarium specimen that had been
annotated by Gaudichaud. Gaudichaud noted that the country of
origin was unknown, and that it had been long cultivated in the
Both Miquel (1861, 1868) and de Candolle (1868) recorded it as
an uncertain species, Miquel first suggesting that it may have
been the same as C. glauca, and later suggesting synonymy
with C. rumphii. De Candolle proposed C. thouarsii
at a possible synonym. The name C. undulata did not arise
in the literature again until Schuster
(1932) assigned it to material
from The Marianne group, as C. circinalis forma undulata.
He had also, however, included C. tonkinensis and C.
bellefontii as synonyms, although both were recorded as having
come from Tonkin. Kanehira
(1938)Kanehira (1938) mistakenly followed Schuster,
but correctly recognised the affinities of the Micronesian cycads
in transferring Schuster's forma undulata to C. rumphii.
