Relationships of bradyrhizobia from Platypodium and Machaerium (Papilionoideae: tribe Dalbergieae) on Barro Colorado Island, Panama.
Enzyme electrophoresis and rRNA sequencing indicated that root nodule bacteria from the canopy tree Platypodium elegans and the lianas Machaerium milleflorum and Machaerium arboreum on Barro Colorado Island, Panama, were highly diverse on a local scale. A total of 11 distinct multilocus genotypes [ETs (electrophoretic types)] was found among the 33 isolates analysed. On average, ETs differed fr...
متن کاملDevelopmental morphology and structural homology of corolla-androecium synorganization in the tribe Amorpheae (Fabaceae: Papilionoideae).
Comparative developmental morphology was used to assess structural homology of flowers in Dalea, Marina, and Psorothamnus of the tribe Amorpheae (Fabaceae: Papilionoideae). Dalea, Marina, and some species of Psorothamnus have an unusual petal-stamen synorganization (stemonozone) in which free petals are inserted on a region that is continuous with fused stamen filaments. Developmental studies o...
متن کاملAllophylastrum: a new genus of Sapindaceae from northern South America
The new genus Allophylastrum (Sapindaceae) is described from Roraima, Brazil and Guyana. Allophylastrum resembles the genus Allophylus in its vegetative morphology but differs by its apetalous flowers with a cupular nectary disc, 5-6 unequal stamens, and 4- to 5- porate pollen grains. A key is provided to differentiate Allophylastrum from Allophylus. The new species Allophylastrum frutescens is...
متن کاملFlower morphology, pollination biology and mating system of the complex flower of Vigna caracalla (Fabaceae: Papilionoideae).
BACKGROUND AND AIMS Vigna caracalla has the most complex flower among asymmetrical Papilionoideae. The objective of this study was to understand the relationships among floral characteristics, specialization, mating system and the role of floral visitors under different ecological contexts. METHODS Five populations were studied in north-western Argentina, from 700 to 1570 m a.s.l. Anthesis, c...
متن کاملPerspectives in taxonomy and phylogeny of the genus Astragalus (Fabaceae): a review
The genus Astragalus L. (Fabaceae) is reviewed from both phyloenetic and taxonomic points of view. As the largest genus of flowering plants it has attracted many researchers, but much work remains to be done. A short taxonomic history with special focus on infrageneric classification of the genus, a list of phylogenetic studies including the applied markers and sampling strategies as well a...
