“…An infrageneric classification system has been proposed by Le Roux et al (2013) where the Indian sections Calycinae and Crotalaria have been merged on the basis of molecular as well as morphological data. The broadened circumscription is also congruent with the earlier investigation of Subramaniam et al (2013). However, members of the Bracteatae clade (forming a part of Crotalaria section Calycinae clade), form a strongly supported group (Subramaniam et al 2013).…”

“…The above combination of features characterize the members of this subsection, and strongly suggest the reinstatement of this Crotalaria subsection Bracteatae in the section Calycinae. Although, the clade is strongly supported, but the members of this clade are nested within the section Calycinae which makes it difficult to reinstate the subsection (Subramaniam et al 2013). Reinstatement of this subsection would create non-monophyly in the section Calycinae.…”

“…of the genus in the Crotalaria clade comprising the genera Crotalaria, Bolusia and Euchlora hirsuta. Phylogenetic studies on Indian Crotalaria (Subramaniam et al 2013) reveal that Crotalaria section Crotalaria is non-monophyletic and also includes members of Crotalaria section Calycinae Wight & Arn. (all simple leaved species, with few exceptions).…”

“…Also, the morphology of the members of this subsection is quite distinct and easily recognizable. Since 75 % of the members of this complex are endemic to Western Ghats (India) (Ansari 2008;Subramaniam et al 2013), it is important to resolve this complex because of the peculiar combination of the morphological characters. Present study is the first attempt to classify Crotalaria subsection Bracteatae and to establish its status in the genus and also to resolve the disparities in the circumscription of these species based on morphological and molecular markers.…”

The existing sectional classification of the genus Crotalaria has merged the Indian sections Calycinae and Crotalaria under the section Calycinae Wight & Arn. emend. M.M.Le Roux & B.-E.van Wyk.Crotalaria subsection Bracteatae is re-evaluated to ascertain its position in the Calycinae clade. Evidences from morphological and molecular sequence data (ITS and trnL-F regions) are used to assess the subsectional position of Bracteatae. Within the recognized 12 species in the subsection, the morphological characters currently used to distinguish these species, are insignificant and overlapping and do not merit diagnostic characters of the species. Examination of the types and vouchers at different herbaria and specimens collected during field trips enabled us for a new interpretation of the existing circumscription of the species. Further, pod anatomical and molecular sequence data were also used for the delimitation of the species. Based on the results of the above studies, a new circumscription has been formalized here and contains five recognized species in the Bracteatae clade, viz., C. berteroana DC., C. longipes Wight & Arn., C. paniculata Willd., C. pulchra DC. and C. pellita DC. of the section Calycinae emend. M.M.Le Roux & B.-E.van Wyk. Crotalaria subsection Bracteatae appeared to be a well supported monophyletic group, but nested within the Calycinae clade. In order to maintain the monophyly of Crotalaria section Calycinae, Bracteatae is synonymized with the former.

Alysicarpus Necker ex Desvaux (Fabaceae, Desmodieae) consists of ~30 species that are distributed in tropical and subtropical regions of theworld. In India, the genus is represented by ca. 18 species, ofwhich seven are endemic. Sequences of the nuclear Internal transcribed spacer from38 accessions representing 16 Indian specieswere subjected to phylogenetic analyses. The ITS sequence data strongly support the monophyly of the genus Alysicarpus. Analyses revealed four major well-supported clades within Alysicarpus. Ancestral state reconstructions were done for two morphological characters, namely calyx length in relation to pod (macrocalyx and microcalyx) and pod surface ornamentation (transversely rugose and nonrugose). The present study is the first report on molecular systematics of Indian Alysicarpus.
