I heard that I missed out on the splitting up of _Hibiscus_, with a
segregate _Talipariti_?
PvR.


Paul A. Fryxell, Talipariti (Malvaceae), a segregate from Hibiscus,
Contributions from the University of Michigan Herbarium, 23: 225-270
(2001) [I've seen bits of this.]

Talipariti consists of 22 species from section Azanzae (archiboldianum,
aruense, bornense, bowersieae, celebicum, crestaense, dalbertisii,
elatum, ellipticifolium, glabrum, hamabo, hastatum, leeuwenii,
macrophyllum, pleijtei, potteri, pseudotiliaceum, schlechteri,
sepikense, simile, tiliaceum, tortuosum; pernambucense is treated as a
variety of tiliaceum.) I've been told that not all species of Azanzae
were transferred, but I wasn't told of the identity of any untransferred
species.

However DNA sequence data has Talipariti nested within Hibiscus. See
B.E. Pfeil et al, Phylogeny of Hibiscus and the Tribe Hibisceae
(Malvaceae) Using Chloroplast DNA Sequences of ndfH and the rpl16 Intron
(2002)

Talipariti (2 species sampled) falls with Papuodendron (1 species
sampled). On this data one can't say whether Papuodendron (2 species
recognised) is sister to or nested within Talipariti. Jointly they are
sister to Hibiscus section Furcaria.

Decaschistia is nested within Furcaria (except that Decaschistia is not
extensively sampled, so there are other hypotheses consistent with the
DNA sequence data). All sampled species in "Malvavisceae" (sunk in
Hibisceae in Kubitzki & Bayer) fall into a clade containing parts of
Hibiscus section Ketmia, sections Solandra and Panduriformes, and
Abelmoschus and Fioria. (All subject to qualifications on sampling.)

Hence, Hibiscus may look rather different in the future, but I'm not
able to predict what it will look like.
