“…Apoucouita. This arrangement pattern, as well as the presence of accessory bundles (with accessory bundles in the wings, when such wings are present), have already been reported in the literature for Chamaecrista belonging to different sections (Metcalfe & Chalk 1950;Coutinho et al 2013;. Although type XII and XIV of vascular arrangement of the petiole were exclusively observed in C. duartei and C. polystachya, this character has proven difficult to use in the identification of both species since other types of vascular arrangements in the petiole were also found.…”

“…Apoucouita can be quite difficult to identify since vegetative material may resemble species of the genus Inga, especially because of the winged petiole in some species and the always-present leaf extrafloral nectaries. Morphoanatomical characters have proven to be useful in taxonomic and phylogenetic research of not only Leguminosae (Solereder 1908;Metcalfe & Chalk 1950;Lackey 1978;Luckow 2002;Arambarri et al 2006) but also Chamaecrista (Coutinho et al 2013;2015;.…”

“…These authors themselves stated that 'the varietal key might be emended as follows, but requires testing against the full range of material available to the taximetric study' (Irwin & Barneby 1977). Morphoanatomy has proven useful in supporting molecular studies within Chamaecrista, which elevated all varieties to the species level (Conceição et al 2008;Coutinho et al 2013).…”

Little attention has been paid to species of Chamaecrista sect. Apoucouita (Leguminosae-Caesalpinioideae), especially regarding anatomical studies. When only vegetative material is available, the identifi cation of such species may be diffi cult. Additionally, vegetative material of some species of C. sect. Apoucouita may be even harder to identify because they can resemble species of Inga Mill. (Leguminosae-Mimosoideae). Th e present study focused on recognizing morphoanatomical characters of leaves that are taxonomically useful for the species of C. sect. Apoucouita by employing standard anatomical techniques. Th e arrangement of the vascular system in the petiole/rachis, dorsiventral mesophyll, mucilage idioblasts in the epidermis of leafl ets and hypostomatic leaves were some of the characters shared by all species studied. Length of the petiole, position and type of extrafl oral nectaries, leafl et venation, presence and type of papillae on the epidermis of the leafl et blades and sclereids in the mesophyll were some of the characters useful in the distinction of taxa. Th e vascular arrangement of the petiole/rachis is a promising character in the distinction of species of C. sect. Apoucouita and Inga. Based on morphoanatomical data, the taxonomic revision of some species and varieties ascribed to C. sect. Apoucouita is suggested.

“…Chamaecrista and Caliciopsis studied, non-vascularized colleters have bee previously reported for other species of Chamaecrista belonging to other sections (De-Paula & Oliveira 2007;Coutinho et al 2013;, other species of Caesalpinioideae (Paiva & Machado 2006b;Paiva 2009;Souza 2014), and even species of other families (Paiva & Machado 2006a;Paiva 2009;Vitarelli & Santos 2009;Silva et al 2012;Dalvi et al 2013).

“…In Chamaecrista, colleters have been described in vegetative and reproductive organs of species belonging to sections Absus, Apoucouita, Grimaldia, Chamaecrista and Xerocalyx (Coutinho et al 2013;. Six types of colleters were morphoanatomically described: short digitiform, long digitiform, short bottle-shaped, long bottle-shaped, clubshaped and racket-shaped (Coutinho et al 2013;.…”

Th e genus Chamaecrista contains ca. 330 species organized into six sections, of which section Chamaecrista is the second largest (ca.75 species) distributed among six series, while the section Caliciopsis contains only two species. Colleters have been described in the genus Chamaecrista and they show potential taxonomic and phylogenetic signifi cance. Th ey are associated with lubrication, desiccation prevention and protection from microbial attacks of young developing organs. Although six types of colleters have been described for the genus Chamaecrista, there have been no studies focusing on the diversity of colleters in the sections Chamaecrista and Caliciopsis. Samples from developing leaves and fl owers of both sections were obtained from herbarium and fi eld collections and subjected to standard methodologies for both light and scanning electron microscopy. Histochemical tests were also performed to determine the nature of the exudates. Five types of non-vascularized colleters were found: short digitiform, long digitiform, club-shaped, pyriform and short bottle-shaped. Polysaccharides, pectins, lipids and proteins were detected in the exudates of all types of colleters. Among the fi ve types of colleters observed, pyriform is a novelty for Chamaecrista, reinforcing the signifi cant morphological diversity of these secretory structures in this genus.
