“…As Jacqueshuberia quinquangulata apresenta populações restritas a uma reduzida área de campina mal drenada do município de Gurupá (Silva & Graham 1980), caracterizando seu estado de conservação como "em perigo", segundo IUCN (2010), entretanto, frente a iminente exploração econômica e possível perda de habitat na região, poderá ser conduzida a categoria de planta extinta.…”

Leguminosae é dominante nas formações vegetacionais amazônicas; e, nesse contexto, o arquipélago de Marajó possui destaque, pois inclui várias dessas formações. Este trabalho objetiva fornecer uma listagem das espécies de Leguminosae registradas no arquipélago de Marajó e analisar a sua distribuição geográfica. Analisaram-se dados de herbários, literatura e coletas, e a partir de então foram definidos os padrões de distribuição. Foram registradas 241 espécies em 80 gêneros as quais seis são novos registros para o Estado do Pará. Os gêneros mais representativos foram Inga, Mimosa, Aeschynomene e Machaerium. A subfamília Papilionoideae apresentou maior número de gêneros e espécies. Jacqueshuberia quinquangulata é endêmica da região estudada. A análise da distribuição mostrou o predomínio de espécies amplamente distribuídas pela América do Sul. O arquipélago, por sua heterogeneidade fisionômica, é um sítio diverso de Leguminosae na Amazônia, com cerca de 30% da flora específica da família no Estado do Pará.

“…Regarding the floral morphology of the related genera in Tachigali clade, Arapatiella and Jacqueshuberia species have morphologically similar flowers within Tachigali . Arapatiella have flowers with tubular hypanthium, oval petals, unguiculate and stipulated ovary ( Cowan, 1973 ; Silva, 1976 ; Cowan, 1981 ); while Jacquehusberia presents flowers with cupular hypanthium, ovate petals, and sessile ovary ( Silva & Graham, 1980 ). Both genera have bigger flowers then observed in Tachigali ( Silva et al, 2016 ).…”

Background The present ontogenetic study reveals variations throughout floral development in three morphologically representative species from the genus Tachigali, allowing a better understanding of floral organs diversity, flower symmetry and their homologies, especially in Fabaceae, a diverse family that exhibits a wide variation in floral architecture. Tachigali (Caesalpinioideae) corresponds to an important Neotropical legumes tree genus with 58 species in Brazil. Species of the genus Sclerolobium Vogel were incorporated in its circumscription, increasing the diversity of its floral morphology. Methods This work aims to perform an ontogenetic study of T. denudata, T. paratyensis and T. spathulipetala, morphologically representative species of Tachigali, in order to describe the floral development and to better comprehend the floral morphology varieties among the species, using scanning electron microscopy. Results We found the studied species to have floral buds with acropetal and helical development along the inflorescence axis; sepals and petals with helical development, varying the position of the primordia in the bud, according to the different species; stamens with unilateral development and carpel with adaxial curvature. These data correspond to original records of Tachigali ontogeny and contribute to an improved understanding of floral morphology and symmetry with data related to the zygomorphic and early development of the sepals and petals.

“…The fruits are dehiscent, linear, with 4–8 seeds. The genus was last revised by Silva and Graham (1980) , including a key to all species. Four species were subsequently described ( Cowan 1985 ; Barneby 1990 ; Stergios and Berry 1996 ).…”

Caesalpinioideae is the second largest subfamily of legumes (Leguminosae) with ca. 4680 species and 163 genera. It is an ecologically and economically important group formed of mostly woody perennials that range from large canopy emergent trees to functionally herbaceous geoxyles, lianas and shrubs, and which has a global distribution, occurring on every continent except Antarctica. Following the recent re-circumscription of 15 Caesalpinioideae genera as presented in Advances in Legume Systematics 14, Part 1, and using as a basis a phylogenomic analysis of 997 nuclear gene sequences for 420 species and all but five of the genera currently recognised in the subfamily, we present a new higher-level classification for the subfamily. The new classification of Caesalpinioideae comprises eleven tribes, all of which are either new, reinstated or re-circumscribed at this rank: Caesalpinieae Rchb. (27 genera / ca. 223 species), Campsiandreae LPWG (2 / 5–22), Cassieae Bronn (7 / 695), Ceratonieae Rchb. (4 / 6), Dimorphandreae Benth. (4 / 35), Erythrophleeae LPWG (2 /13), Gleditsieae Nakai (3 / 20), Mimoseae Bronn (100 / ca. 3510), Pterogyneae LPWG (1 / 1), Schizolobieae Nakai (8 / 42–43), Sclerolobieae Benth. & Hook. f. (5 / ca. 113). Although many of these lineages have been recognised and named in the past, either as tribes or informal generic groups, their circumscriptions have varied widely and changed over the past decades, such that all the tribes described here differ in generic membership from those previously recognised. Importantly, the approximately 3500 species and 100 genera of the former subfamily Mimosoideae are now placed in the reinstated, but newly circumscribed, tribe Mimoseae. Because of the large size and ecological importance of the tribe, we also provide a clade-based classification system for Mimoseae that includes 17 named lower-level clades. Fourteen of the 100 Mimoseae genera remain unplaced in these lower-level clades: eight are resolved in two grades and six are phylogenetically isolated monogeneric lineages. In addition to the new classification, we provide a key to genera, morphological descriptions and notes for all 163 genera, all tribes, and all named clades. The diversity of growth forms, foliage, flowers and fruits are illustrated for all genera, and for each genus we also provide a distribution map, based on quality-controlled herbarium specimen localities. A glossary for specialised terms used in legume morphology is provided. This new phylogenetically based classification of Caesalpinioideae provides a solid system for communication and a framework for downstream analyses of biogeography, trait evolution and diversification, as well as for taxonomic revision of still understudied genera.
