Etymology:— “ absus ” from Latin means clothing, alluding to the trichomes present throughout the plant.

Geographical distribution and habitat:— Chamaecrista absus is the species with the largest area of occurrence of the entire genus, has a pantropical distribution and can be found in four continents: Africa, America, Asia and Oceania (Fig. 37A). In America it is reported from southern Arizona in the United States to Paraguay, being more frequent in Mexico and Central American countries. In Brazil it is found as native in the coastal regions of Bahia, Ceará and Rio Grande do Norte in restingas and degraded and/or anthropized environments, or as cultivated/spontaneous in the rest of the country. In Africa it occurs in practically every continent, except in the North region, growing in savannah areas, forest edges or pasture areas. In Asia it is native to Southeast Asia, occurring in India, Malaysia, Indonesia and Southeast China ( Wang et al. 2014). In Oceania it is recorded for Papua New Guinea and the northern portion of Australia. Found between 100 and 1650 m altitude. The low representation of Ch. absus in South America led Irwin & Barneby in 1978 to consider the species as introduced in this region, as well as in other areas of the world (e.g. Madagascar) although the place of origin is still unknown.

The species’ great ability to establish itself in different environments is probably due to its nodulation ability. Chamaecrista absus exhibits a pioneer plant behavior, with rapid and annual growth and occurs frequently in environments that have been recently degraded or disturbed, which is not common in plants of the section Absus , but quite frequent in species of the section Chamaecrista (e.g. Ch. nictitans ( Linnaeus 1753: 380) Moench (1794: 272) and Ch. rotundifolia ( Persoon 1805: 456) Greene (1899: 31)) which grow in similar environments and are capable of nodulating as well as Ch. absus .

Flowering and fruiting:— Chamaecrista absus is a species of annual growth with autogamous flowers, it has a very fast flowering period compared to the other species studied, and can be found with flowers and fruits at the same time all year round, flowering being more common in times of greater rainfall.

Conservation status:—The conservation of the species is given as Least Concern (LC) due to its wide distribution, for demonstrating excellent ability to colonize different environments and for being present in different environmental protection/conservation units around the world.

Taxonomic history and adjustments:— Cassia absus was described by Linnaeus in 1753 in Species Plantarum. In 1805, Schrank established the genus Grimaldia citing Grimaldia opifera as a type species. About 26 years later, Link (1831) combined C. absus into Grimaldia naming Grimaldia absus (Linnaeus) Link. In 1832 Roxburgh in the work “Flora of the plants of India ” combines C. absus in the genus Senna , naming Senna absus . In 1930, Britton & Rose performed the combination of Senna absus on the genus Grimaldia , treating it as “ Grimaldia absus (Linnaeus) Britton & Rose ”, however, this is a later homonym and should be disregarded, since the species was combined. first in Grimaldia by Link in 1831. In this same work Britton & Rose synonymized Grimaldia opifera in Grimaldia absus .

In 1978, Irwin & Barneby in a revision of Cassiinae transferred the species of the genus Grimaldia to Cassia subgen. Lasiohegma . Due to the many unique features that Grimaldia absus has (e.g. leaf phyllotaxis, presence of a foliate leafy appendix inter-petiolule, reduced flowers and androecium), Irwin & Barneby (l.c.) chose to consider the species in a monotypic section (= Cassia sect. Grimaldia ) while the other species belonging to the genus Grimaldia were allocated in the section Absus series Absoideae . In the samestudy, the authors described C. absus var. meonandra from Mexico and distinguished from the typical variety by the androecium commonly with (2)3–4 stamens (vs. (2–)5– 6(7) in the typical variety).

In 1978, Irwin & Barneby in a revision of Cassiinae transferred the species of the genus Grimaldia to Cassia subgen. Lasiohegma . Due to the many unique features that G. absus has (e.g. leaf phyllotaxis, presence of a leafy appendix inter-petiolule, reduced flowers and androecium), Irwin & Barneby (l.c.) chose to consider the species in a monotypic section (= Cassia sect. Grimaldia ) while the other species belonging to the ancient genus Grimaldia were allocated in the series Absoideae of the section Absus . This year, the authors described C. absus var. meonandra from Mexico and distinguished from the typical variety by the androecium commonly with (2)3–4 stamens vs. (2–)5–6(7) in the typical variety.

Analyzing the original works, we found that Cassia babylonica , Grimaldia opifera and Senna exigua are nomina nuda, as they were created without description, diagnosis or indication of a reference (e.g. illustration or specimen in herbarium); and we corroborate with the synonym Cassia thonningii (valid name) as it is just a variation of the species. Finally, analyzing collections from Central and South America, Africa, Asia and Australia, we concluded that Ch. absus var. meonandra does not hold up as a distinct taxon based solely on the variation of its stamens. The androecium with 5–7 stamens seems to be the most common variation for the species, as also noted by Irwin & Barneby (1978). However, it is not difficult to find flowers with androecium with 2–4 stamens, and this condition is not unique to the populations of Mexico as postulated by Irwin & Barneby (l.c.) when establishing the meonandra variety. Specimens from Africa and Asia have been found with flowers with the following stamen variations: 2–4, 3–5, 5–6, and 5–7. Thus, the only diagnostic feature of the meonandra variety is superimposed and continuous and must be considered a common variation of a polymorphic and widely distributed species. In view of this, we admit here Ch. absus as a species without infraspecific categories with the synonymization of Ch. absus var. meonandra .

Characterization and morphological relationships:—Although it has a wide distribution and certain polymorphism, Ch. absus has conserved diagnostic characters and is easily recognized as it is the only species in the section Absus to have: adult leaves alternate with a filiform, lingual or triangular leafy appendix inter-petiolule; flowers conspicuously reduced (5–9 mm long); androecium with (2)3–5(–7) stamens; fillets similar in size to anthers and style as short as the ovary (1.3–3 mm long); in addition to the presence of root nodules. Such characters are constant in all analyzed morphotypes and together are determinant to the recognition of the species. Other relevant characteristics of the species, but not exclusive, are the sessile and terminal inflorescences or opposite the leaves; flowers short pedicelled with 5 flat petals, the inner one slightly falcate and not curled or encircling the stamens, and the color of the petals that vary from orange, red or yellow.

Due to the presence of leafy appendix inter-petiolule, Ch. absus has already been confused, allocated and described in the genus Senna , as such structures were wrongly interpreted as convex nectaries ( Roxburgh 1832). Irwin & Barneby (1978) already mentioned the uncertainty about the origin and function of the leafy appendix of Ch. absus . Morphologically, the flat, foliate and non-secretory structure of the appendix is more similar to stipules than nectaries. However, a deeper micromorphological analysis (ontogenetic and anatomical) is necessary to elucidate the nature of this structure in terms of its origin and function.

Despite so many peculiarities, Chamaecrista absus is vegetatively similar to the species of the subsect. Absus , sometimes being confused in herbarium collections with Ch. hispidula and Ch. fagonioides . The similarity of these taxa is attributed to the leaves always with two pairs of papyraceous or membranous leaflets with the distal pair slightly larger than the proximal pair and with an oblique base, while the proximal pair has an obtuse or rounded base in addition to similar shapes and dimensions and branches with glandular trichomes. However, the diagnostic features of Ch. absus listed in the preceding paragraphs make it unmistakable with any species of the genus.
