(L. Linden & Rodigas) Rodigas, Ill. hortic. 33: 27 (1886);
Zamia tonkinensis L. Linden & Rodigas, Ill. hortic.
32: Planche 547. 1885.
TIn the absence of any known preserved specimens, the plate,
planche 547 in Ill. hortic. 32 (1885) must be accepted as the type.
This plate clearly shows numerous leaves with relatively short, thorny
petioles and very broad leaflets tapering more or less equally towards
both base and apex. This condition is not found in any known Vietnamese
species, and may be an artifact of the illustration. The plate
therefore cannot be matched unequivocally with any known species
and, in the absence of a type specimen, the name must be excluded.
