Caesalpinioideae is a botanical name at the rank of subfamily, placed in the large family Fabaceae or Leguminosae. Its name is formed from the generic name Caesalpinia . It is known also as the peacock flower subfamily.[5] The Caesalpinioideae are mainly trees distributed in the moist tropics, but include such temperate species as the honeylocust (Gleditsia triacanthos ) and Kentucky coffeetree (Gymnocladus dioicus ). It has the following clade-based definition:

The most inclusive crown clade containing Arcoa gonavensis Urb. and Mimosa pudica L., but not Bobgunnia fistuloides (Harms) J. H. Kirkbr. & Wiersema, Duparquetia orchidacea Baill., or Poeppigia procera C.Presl[6]

In some classifications, for example the Cronquist system, the group is recognized at the rank of family, Caesalpiniaceae.

Characteristics

[edit ]
  • Specialised extrafloral nectaries often present on the petiole and / or on the primary and secondary rachises, usually between pinnae or leaflet pairs
  • Leaves commonly bipinnate
  • Inflorescences globose, spicate
  • Aestivation valvate
  • Anthers often with a stipitate or sessile apical gland
  • Pollen commonly in tetrads, bitetrads or polyads
  • Seeds usually with an open or closed pleurogram on both faces
  • Root nodules variably present and indeterminate
  • 10 Stamens, aside from various core mimosoid genera bearing a few factors more

Taxonomy

Phylogenetics

[edit ]

Caesalpinioideae, as it was traditionally circumscribed, was paraphyletic. Several molecular phylogenies in the early 2000s showed that the other two subfamilies of Fabaceae (Faboideae and Mimosoideae) were both nested within Caesalpinioideae.[7] [8] [9] [10] Consequently, the subfamilies of Fabaceae were reorganized to make them monophyletic.[6] Caesalpinioideae, as currently defined, contains the following subclades:[8]

Fabales

Faboideae (outgroup)

Caesalpinioideae

Umtiza clade

Cassieae clade

Dimorphandra group A

Tachigali clade

Peltophorum clade

Dimorphandra group B (with the mimosoid clade nested within)
