“…The anatomy of the pericarp is too conservative to be used diagnostically at the generic level. In Indigofera glabra , the exocarp is biseriate, a character also present in the Neotropical species Indigofera lespedezioides Kunth (Leite et al ., ). The exocarp is mostly thin‐walled in Neotropical species [ Indigofera campestris Bong.…”

Pod morphology and anatomy have been studied in 28 species and four varieties of Indian Indigofera. Pods of Indigofera spp. differ with respect to size, the relative thickness of the fruit wall, the number of sclerenchymatous layers in the endocarp, the presence/absence of hypodermis and trichomes, and the presence of separation tissue. Anatomically, the pericarp is broadly characterized into three types: type I (thin pericarp and three to five sclerenchymatous layers in the endocarp), type II (intermediary pericarp thickness and six to eight sclerenchymatous layers), and type III (thick pericarp and more than eight sclerenchymatous layers). The distribution of these types across the tribe is not congruent with the current phylogenetic analyses. Type III pericarp (present in the early diverging lineages of the tribe) represents the most primitive state, whereas type I and type II pericarps are derived. Fruits of Indigofera generally show normal explosive dehiscence as a means of dispersal of seeds, although some species show adaptations for dispersal by wind. In Indigofera, dehiscence is caused by a separation layer present at the dorsal and ventral sutures except in some species (Indigofera hochstetteri, Indigofera karnatakana, Indigofera glandulosa var. sykesii, and Indigofera trita var. scabra) in which no separation tissue is present; these species show delayed dehiscence or an indehiscent condition. The indehiscent pod type is considered to be apomorphic. The taxonomic, functional, and evolutionary significance of morphological and anatomical features in fruits of the genus Indigofera has been evaluated. © 2014 The Linnean Society of London, Botanical Journal of the Linnean Society, 2014, 176, 260–276.

“…However, these characters have been shown to be of great taxonomic and systematic importance in some Eudicot groups, such as Melastomataceae (Clausing et al 2000), Fabaceae (Leite et al 2009), Solanaceae (Chiarini and Barboza 2009), and Caprifoliaceae (Jacobs et al 2009). …”

The genus Arachis encompasses 80 validly described species and the most striking characteristics is the geocarpic fruit, which occurs in every species of the genus. Taking into consideration that much of the current knowledge about this subject is based on the anatomy and morphology of A. hypogaea, a cultivated species with fruits that were modified during domestication, the objective of this study was to learn more about the development of the geocarpic fruits of wild species of Arachis (A. paraguariensis, A. pintoi, A. stenosperma, and A. tuberosa), and to provide characters that can be used in future phylogenetic works about this group. Buds, flowers and fruits at different stages of development were collected and processed according to standard methods used for light field, interferential contrast, and scanning electron microscopy. Although the geocarpic fruits of the wild species share many adaptations, this study identified potentially diagnostic infrageneric characters, such as the type of trichomes on the pericarp, the presence of sclerenchyma caps in the bundles of the pericarp of the seed chamber of the fruit and isthmus, the presence of tracheoid cells in the pith of the isthmus, the location of crystalliferous cells, the presence of tannins in the cells of mesocarp outer layers, and the presence of projections in the sclerenchyma tissue. In addition, this article brings some inferences about functional characteristics of this peculiar geocarpic fruit.
