A New Species of Zornia (Leguminosae, Papilionoideae) from Northeastern Brazil

Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Zornia grandiflora Fort.-Perez & A. M. G. Azevedo (Leguminosae, Papilionoideae), a new species from Bahia and Pernambuco states in northeastern Brazil, is described and illustrated. The new species is assigned to section Anisophylla Mohlenbr. of subgenus Zornia J. F. Gmel. Zornia grandiflora is similar to Z. sericea Moric., sharing erect stems and ovate to elliptic bracteoles. It can be distinguished from Z. sericea and from other species within Zornia sect. Anisophylla by the large standard (13-17 mm long).2013537Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Fundacao dui Amparo a Pesquisa do Estado de Silo Paulo [06/6164-8-4]Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)CNPq [141324/2005-8]Fundacao dui Amparo a Pesquisa do Estado de Silo Paulo [06/6164-8-4

A synopsis of the genus Deguelia (Leguminosae, Papilionoideae, Millettieae) in Brazil

Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Considering the recent reestablishment of Deguelia, six new combinations and 14 lectotypifications are proposed here. A key is provided for the identification of the 15 species of Deguelia that occur in Brazil, along with nomenclatural notes, comments on ecology and distribution, and discussions of diagnostic features.6611232Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES

Seed and embryo morphology of Poecilanthe (Fabaceae, Papilionoideae, Brongniartieae)

Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)This work analyses and describes seed and embryo morphology of eight Poecilanthe species. Poecilanthe species can be divided in four groups based on seed and embryo characters: (1) P. amazonica-type has overgrown seeds, bears cataphylls on the epicotyl and has an inflexed hypocotyls-root axis; (2) P. effusa-type has two types of trichomes on the epicotyl, which is longer than the hypocotyls-root axis; (3) P. parvilora-type has a visible lens and the raphe runs around three-quarters of the seed circumference; and P. grandiflora-type bears a one-lipped rim aril. Poecilanthe presents a remarkable diversity both in seed and embryo, which reinforces the belief that the genus is not monophyletic. Moreover, our results support the three major clades recognized by a preliminary phylogeny.

Morphological analysis and re-examination of the taxonomic circumscription of Acosmium (Leguminosae, Papilionoideae, Sophoreae)

Acosmium Schott is a Neotropical genus of ca. 17 species of trees with non-papilionoid, actinomorphic flowers. it has been included in the genistoid clade (Leguminosae, Papilionoideae) in recent phylogenetic analyses. A morphology-based cladistic analysis was performed to test the currently assumed monophyly of Acosmium, assess the validity of the infrageneric classification of Yakovlev, and detect synapomorphies and other diagnostic characters in Acosmium and related taxa. Thirty-four species representing ten genera of subfamily Papilionoideae were included in the analysis: all accepted species of the four sections of Acosmium together with species of Bowdichia, Clathrotropis, Diplotropis, Bolusanthus, Cadia, Poecilanthe, Cyclolobium, and Ormosia; two species of Luetzelburgia were selected as outgroups. The results do not support the monophyly of Acosmium; the species of this genus fall into three distinct, not closely related clades that correspond to the sections of Acosmium established by Yakoviev except for sect. Mesitis that merges into sect. Leptolobium. We propose: (1) recognizing a narrowly circumscribed genus Acosmium; (2) reinstating the generic name Leptolobium Vogel, encompassing sections Leptolobium and Mesitis; and (3) segregating A. praeclarum (Sandwith) Yakovlev into a new genus, Guianodendron. The phylogenetic relevance of some new or neglected characters, especially from bud architecture, seed, and seedling morphology is emphasized.56243945

The taxonomy of some Swartzieae (Leguminosae, subfam. Papilionoideae) from southeastern Brazil

Three new species of Swartzieae are described and illustrated: Swartzia alternifoliolata, S, capixabensis, and Zollernia cowanii. Swartzia apetala var, blanchetii and var, subcordata are considered to he synonyms of S. apetala var. apetala, and S, grazielana a synonym of S. macrostachya var. macrostachya. Keys to southeastern Brazil members of Swartzia and Zollernia are provided.51214915

Two new species of Leptolobium (Leguminosae, Papilionoideae) from Brazil

Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Two new species of Leptolobium from Brazil are described and illustrated. Leptolobium araguaiense, restricted to northern Brazil, is similar to L. panamense, but differs in raceme length, ovary pubescence, flower and bract length, hilum shape, habit, geographical distribution, and preferential habitat. Leptolobium multijugum, from mid-western Brazil, is perhaps most closely related to L. glaziovianum, but it has more numerous leaflets and smaller bracts and bracteoles than any other species in the genus.6212025Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)FAPESP [00/09429-0

Comparative leaflet anatomy in Myrocarpus Allemao, Myroxylon L. f and Myrospermum Jacq. (Leguminosae-Papilionoideae-Sophoreae) species

A comparative study on anatomical characters of the leaflets of all species of Myrocarpus, Myroxylon and Myrospermum was carried out in order to evaluate their potential value in taxonomy. The study showed that among the investigated characters the arrangement of the main vascular bundles as seen in transverse section, the presence or absence of secretary structures in the midrib, the occurrence and position of papillose epidermal cells, and mesophyll organization present meaningful variation between the species and in combination or uniquely their occurrence can be used to identify the species. Some of the obtained anatomical data support generic or specific circumscriptions and are listed for the first time for most of the species of Myrocarpus, Myroxylon and Myrospermum.

A new species of Crotalaria (Leguminosae, Papilionoideae) from southeastern Brazil

Crotalaria miottoae, a new species of Leguminosae from southeastern Brazil. is described and illustrated. The new species is close to Crotalaria vitellina Ker Gawler, but differs in having larger wing petals, fruits, and seeds, in having terminal inflorescences, rarely leaf-opposed, and the leaflets usually rhombic or narrowly elliptic.15341842

Mimosa foreroana (Leguminosae, Mimosoideae), a New Species from Narino, Colombia

Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Mimosa foreroana, a new species of Mimosa sect. Mimadenia ser. Glanduliferae, is described and illustrated. It is apparently endemic to vereda Ijagui, in the Department of Narino, Colombia. This species is distinguished by a combination of characters, including minute glands on vegetative and reproductive structures, leaves with two to three pairs of pinnae and one to three pairs of leaflets per pinna, and short tub-shaped or trough-shaped nectaries near mid-petiole and close to the insertion of the pinnae and leaflets. In addition, scanning electron micrographs of the glands, a map of distribution, and a key to the species of Mimosa ser. Glanduliferae are presented.372437441New York Botanical GardenNYBGFundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)FAPESP [2009/51593-6
