Possible relationships between nodulated and non-nodulated groups in the Caesalpinioideae.
The position of Papilionoideae in this diagram can be ignored. (After Lewis, 2005a.)
since Sprent (2001) is that
Sclerolobium
has been incorporated into
Tachigali
. Both can
nodulate, although this was not one of the properties used in the reclassification. The
seven genera known to nodulate (
Campsiandra, Chidlowia, Dimorphandra, Erythrophleum,
Melanoxylon, Moldenhawera
and
Tachigali
) account for 171 of the 429 species in tribe
Caesalpinieae. Again, this is a significant proportion, equal or exceeding that in some
tribes of the Papilionoideae. All nodulating caesalpinioid genera, except
Chidlowia
,a
monotypic genus from tropical Africa, and
Erythrophleum
, which is found in Africa
and Australia, together with some herbaceous pan-tropical species of
Chamaecrista
,
