Cultivated as an ornamental plant in southern United States.
Hooker first determined that Graham's Janipha loeflingii var multifida was a distinct
species in the genus Manibot. Mueller von Argau (1874) apparently did not see the
relationship between Graham's variety and his new species, M. tweedieana, although he
had earlier (1866) transferred correctly Janipha loeflingii H.B.K. var Manihot.
multifida Graham to
Croizat (1944) said that M. tweedieana Muell-Arg. was incorrect because (fide
Croizat) Pohl's M. flabellifolia was the correct species. Croizat incorrectly synonymized
tweedieana under Pohl's flabellifolia even though Pohl's species itself is but a variation of
M. esculenta.
According to Article 60 of the International Rules, the varietal epithet multifida
published by Graham has no priority as a species epithet.
The roots of Manihot grahami are slender, never enlarged. For this reason, it would
not seem to be a good candidate for breeding work to increase yield of M. esculenta. On
the other hand if one is breeding for cool temperature tolerance, this species might be
useful, particularly if representatives from the southern limits of its range were chosen.
