Morphological and taxonomic studies have proposed changing the circumscription of Acosmium, with the recognition of two additional genera, Leptolobium and Guianodendron. A study on seedling morphology of all accepted species of Acosmium s.str., five species of Leptolobium, and Guianodendron praeclarum is presented, aiming to evaluate the systematic value of these characters. Guianodendron has crypto-hypogeal reserve seedlings, while Acosmium and Leptolobium have phanero-epigeal seedlings with… 
Morphology of fruits, seeds, seedlings and saplings of three species of Macrolobium Schreb. (Leguminosae, Caesalpinioideae) in the Brazilian Amazon floodplain
TLDR
This study aimed to describe and characterize the morphology of the fruits, seeds, seedlings and saplings of Macrolobium acaciifolium, M. b ifolium and M. pendulum, as well as to evaluate the ecological, taxonomic and phylogenetic value of the structures identified.
Morphology of seeds and seedlings of four species of Vigna Savi (Leguminosae, Phaseolinae)
TLDR
Four neotropical species of Vigna Savi have potential value as forage crops or ornamentals and could be cultivated in tropical or subtropical areas, even on floodplains, and the seed morphology, germination pattern, and seedling development were studied.
Morfologia de plântulas das espécies de Rhynchosia (Leguminosae, Papilionoideae) de Roraima, Brasil
TLDR
The results show that morphological diversity found among seedlings of the studied species can be used to identify them at the specific level, and the morphological variation found in Rhynchosia is discussed.
Números cromossômicos em espécies de Acosmium Schott e Leptolobium Vogel (Leguminosae, Papilionoideae)
TLDR
The results showed that chromosome numbers of Acosmium and Leptolobium species are homogeneous, confirming the basic number x = 9 for both genera, and therefore, chromosome numbers do not provide a useful taxonomic character distinguishing AcOSmium from Leptoobium.
Morfologia de plântulas de Martiodendron excelsum e sua relevância sistemática em Dialiinae (Leguminosae, "Caesalpinioideae”)
TLDR
This paper describes and illustrates the early development and seedling morphology of Martiodendron excelsum, a South American genus with five species of trees belonging to the tribe Cassieae, subtribe Dialiinae (Leguminosae, "Caesalpinioideae”).
Taxonomic relevance of seed and seedling morphology in two Amazonian species of Entada (Leguminosae)
TLDR
Results show consistent quantitative and qualitative differences between these species regarding their seeds and seedlings, supporting a recent treatment of the latter taxon as a distinct species, endemic to Roraima State, northern Amazonia, Brazil.
Morfologia de frutos, sementes e plântulas de Canavalia dictyota Piper (Leguminosae, Papilionoideae)
TLDR
The morphology of fruits, seeds, and seedlings of Canavalia dictyota Piper are described and illustrated and the morphological variation found in the genus is discussed.

Morphological analysis and re‐examination of the taxonomic circumscription of Acosmium (Leguminosae, Papilionoideae, Sophoreae)
TLDR
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.
Seedling morphology in Genisteae (Fabaceae) from south-west Spain
TLDR
It is concluded that, at the generic level, onlyRetama,Lupinusand to some extentAdenocarpus can be distinguished from their seedling characteristics; the other genera have a set of morphological features that do not allow such a segregation.
The dalbergioid legumes (Fabaceae): delimitation of a pantropical monophyletic clade.
TLDR
A monophyletic pantropical group of papilionoid legumes is circumscribed to include all genera previously referred to the tribes Aeschynomeneae and Adesmieae, the subtribe Bryinae of the Desmodieae, and tribe Dalbergieae except Andira, Hymenolobium, Vatairea, and Vatairesopsis.
Morfologia comparada de plântulas e plantas jovens de leguminosas arbóreas nativas: espécies de Phaseoleae, Sophoreae, Swartzieae e Tephrosieae
TLDR
The phyllotaxy of Sophoreae and Swartzieae show alternate nodes, while in Phaseoleae and Tephrosieae the first node is opposite, becoming alternate in the subsequent ones.
Phylogenetic Relationships of Basal Papilionoid Legumes Based Upon Sequences of the Chloroplast trnL Intron
TLDR
Preliminary results indicate radical changes are necessary for papilionoid classification because Swartzieae, Sophoreae, and Dalbergieae are polyphyletic.
Studies on the reproductive biology ofMelastomataceae in “cerrado” vegetation
TLDR
Controlled pollinations and observations of pollen tube growth, pollen fertility and cytological data were studied in 11 species of Melastomataceae growing in “cerrado” in SE Brazil, suggesting the existence of very extensive apomictic complexes comparable to those reported in mainly temperate genera of Asteraceae andRosaceae.
A phylogeny of legumes (Leguminosae) based on analysis of the plastid matK gene resolves many well-supported subclades within the family.
TLDR
Analysis of the matK data consistently resolves but modestly supports a clade comprising papilionoid taxa that accumulate canavanine in the seeds, which suggests a single origin for the biosynthesis of this most commonly produced of the nonprotein amino acids in legumes.
Seedling morphology ofLespedeza (Leguminosae)
TLDR
Seedling morphology was studied in 22 species of Lespedeza to suggest a monophyletic origin for North American species from an Asian ancesfor, and to recognize two seedling types: those with opposite leaves at the first node and those having the first and subsequent leaves alternate.
Flora arbustivo-arbórea do fragmento de floresta estacional semidecidual do Ribeirão Cachoeira, município de Campinas, SP
An inventory of the woody flora (trees and shrubs), was carried out in the Ribeirao Cachoeria forest (233.7ha, 650m high, 46°55'58''W, 22°50'13''S), the second largest and best conserved fragment of
Identification of Vicia seedlings
TLDR
Seedlings of 58 of about 150 species in the genus Vicia (Fabaceae) were grown to the three-eophyll stage and a marked tendency of species regarded as phylogenetically primitive to produce seedlings with bipinnate eophylls having leaflets broader than 2 mm is noted.
