Note

Nielsen (1981a) recognised 21 genera in Ingeae (Table 7), although 4 were not given generic names, but were referred to as ‘Gen. A’ to ‘Gen. D’. He recognised the genus Marmaroxylon, although without a generic number, so that the tribe, to the casual observer, appeared to contain only 20 genera. The genus Punjuba appended by Nielsen (1981a) under “genera and species of unknown affinity” is here treated as a synonym of Abarema, following Barneby & Grimes (1996), although we suggest that this may be reinstated as a good genus in the future. Nielsen (1981a) also included Pithecellobium incuriale (Vell.) Benth. as a “species of unknown affinity” but this is now placed in Leucochloron Barneby & Grimes (1996).

Polhill (1994) increased the number of genera of Ingeae to 25 (Table 7). He recognised Nielsen’s ‘Gen. A’ as Paraserianthes I.C.Nielsen, ‘Gen. B’ as Archidendropsis I.C.Nielsen, ‘Gen. C’ as Pararchidendron I.C.Nielsen, and ‘Gen. D’ as Macrosamanea Britton & Rose ex Britton & Killip. He placed Faidherbia in Ingeae for the first time, reinstated Cathormion, Samanea and Chloroleucon, and recognised the monospecific Obolinga Barneby (subsequently subsumed into Cojoba by Barneby & Grimes, 1997). Zapoteca, a segregate of Calliandra described by Hernández (1986), was also added by Polhill (1994). Klugiodendron, recognised by Nielsen (1981a), was considered a synonym of Abarema by Polhill (1994), and Affonsea was placed as a synonym of Inga, a position later confirmed by Pennington (1997).

The present treatment of Ingeae recognises 36 genera (24 of which are New World endemics) and (935)–951–(966) species (Fig. 27). We follow Barneby & Grimes (1997) in placing Obolinga as a synonym of Cojoba. Eight genera: Blanchetiodendron, Ebenopsis, Hesperalbizia, Hydrochorea, Leucochloron, Painteria, Pseudosamanea, and Sphinga, have either been reinstated or described as new since 1994 (Barneby & Grimes, 1996). Paraserianthes section Falcataria was raised to generic status as Falcataria (I.C.Nielsen) Barneby & Grimes (1996). Balizia Barneby & Grimes (1996) is considered a synonym of Albizia following Rico Arce (1999). Guinetia L.Rico & M.Sousa was described as new (Rico Arce et al., 1999, publ. 2000), and Viguieranthus Villiers in 2002.

Clarification of generic relationships within tribe Ingeae still suffers from a paucity of molecular data, partly due to a lack of appropriate material for DNA extraction of the recently described and reinstated genera. Luckow et al. (2000) included four ingoid genera in their analysis of the basal genera of Mimosoideae. These formed a group together with Faidherbia (then still considered a member of tribe Acacieae, although moved to Ingeae by Polhill (1994)). Barneby & Grimes (1996) concentrating on neotropical taxa, divided American ingoids into five informal alliances: the Abarema-, Samanea-, Chloroleucon-, Pithecellobium- and Inga- alliances. Genera of uncertain position within their system included Albizia, Enterolobium and Cedrelinga. Lysiloma was considered as intermediate between tribes Ingeae and Acacieae. Luckow et al. (2003) carried out a phylogenetic analysis of the Mimosoideae using chloroplast DNA sequence data. They treated sixteen of the 36 ingoid genera recognised in this account, including Faidherbia, but concluded that relationships within the Ingeae are generally unresolved and that, with only a few exceptions, clades within the ingoid part of their topology were not strongly supported. Albizia proved to be polyphyletic, supporting the findings of Grimes (1999).

Any new classification of the Ingeae will require sampling of all the genera not included by Luckow et al. (2003) and more extensive sampling of the larger and putatively non-monophyletic genera. Relationships between ingoid genera and the various elements of a polyphyletic Acacia have still to be resolved, although Luckow et al. (2003) have an Acacia subgenus Phyllodineae clade nested within the Ingeae, suggesting that at least part of Acacia sens. lat. (the Australian phyllodinous acacias) might be included within the Ingeae in the future, or that the Ingeae, as currently circumscribed, may have to be broken up into several distinct suprageneric taxa. Such suggestions are premature as 20 ingoid genera, including Abarema, Archidendron, Pithecellobium, Zygia and the largely Madagascan Viguieranthus have not yet been included in molecular analyses.

Richardson et al. (2001), based on DNA sequence data, indicate that Inga has diversified relatively recently, and that speciation has been concentrated in the past 10 million years, with many species arising as recently as 2 million years ago. All Inga species have simply pinnate (not bipinnate) leaves; in the Mimosoideae, Zygia (1 sp.) and Cojoba (a few spp.) are the only other genera with some species simply pinnate
Vernacular
ingá
Habit
Trees
Ecology
Mostly of lowland and montane rain forest throughout the humid tropics, 0-3000 m, half in rain forest on non-flooded land, half in riparian habitats on periodically flooded land, rarely in seasonally dry areas
Distribution
Neotropics from 24°N in Mexico to 34°S in Uruguay, including 2 spp. restricted to the Caribbean, highest diversity in Peru, Ecuador, Colombia and southern C America. 40 spp. confined to Mexico and southern C America, 75 spp. essentially Amazonian, 33 spp. restricted to coastal Brazil, c. 60 spp. extra-Amazonian within an arc from the Guianas through Colombia to Peru and Bolivia, the remaining spp. (c. 40-45) extending across the Panama isthmus (several of these widespread especially in S America)

[LOWO]
Use
Used as multi-purpose soil restoration and agroforestry trees (e.g., I. edulis Mart., or ice cream bean, guava machete, ingá cipa ), for edible fruits (the white pulp is eaten or used in flavouring desserts), shade for crops, leaf mulch, nitrogen fixing properties, timber, fuelwood and medicine
