A Re-Evaluation of Pollen Morphology and Taxonomy in the Tribe Indigofereae (Leguminosae-Papilionoideae)

Pollen morphology of Indigofera (Fabaceae) in China and its taxonomic implications

“…At least twelve revisions (Schrire 1995) have been proposed based on morphological characters since the establishment of the genus in 1753 (Linnaeus 1753). The most recent and comprehensive classification was proposed by Schrire (1995) based on a morphological cladistic analysis of a dataset containing 58 morphological characters of ca. 600 Indigofereae species, in which 25 sections and 14 groups were recognized within Indigofera.…”

Seed Morphology of Some Species of <i>Indigofera</i> (Fabaceae) from Saudi Arabia (Identification of Species and Systematic Significance)

“…Indigofera L. is a large pantropical genus in Fabaceae, belongs to the tribe Galegeae with c. 720 -730 species [1]. The majority of taxa occur in Africa (c. 520) with other centres of diversity in Arabia to South East Asia, Mexico to subtropical North and South America, Australia and Madagascar.…”

“…Reference [6] were the first to recognize that all species have a persistent fruit-base that remains with the calyx and staminal tube after the valves of the open pod have fallen. Reference [1] considered this is a synapomorphy for the tribe. Reference [7] found that all endemic species of Indigofera in Australia have endocarp tannins present except in I. baileyi and I. mackinlayi.…”

“…Several types of emergences are briefly discussed by Schrire (1995) and Wilson & Rowe (2004). Apart from biramous and simple hairs, glandular hairs, colleters and pearl bodies are found.…”

“…Apart from biramous and simple hairs, glandular hairs, colleters and pearl bodies are found. Schrire (1995) calls the latter two structures pearl bodies, Wilson & Rowe (2004) tend to call most structures emergences. In the species of Indigofera of the Flora Malesiana area hair-like, dark-coloured emergences are common on axial parts, in axils of stipules, leaves, stipellae, leaflets and bracts.…”
