Developmental 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 کاملEvolution and Development in the Amorphoid Clade (amorpheae: Papilionoideae: Leguminosae): Petal Loss and Dedifferentiation
We used comparative developmental morphology to study the evolution of nonpapilionaceous corollas in the amorphoid clade of the tribe Amorpheae (Papilionoideae). This clade consists of five genera in which there are no papilionaceous corollas (five petals differentiated into one banner, two wing, and two keel petals). We studied the ontogenies of three nonpapilionaceous forms: corollas consisti...
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 کاملTaxonomy and phylogeny of the genus Crotalaria (Fabaceae): An overview
Crotalaria (Fabaceae) is the largest legume genus represented by 81 species in India. The existing sectional classification for Crotalaria in India is based on morphological characters and is not completely supported by the molecular phylogenetic studies. Molecular systematic studies of the Indian sections Crotalaria and Calycinae have enabled merging of both these sections into Calycinae. Trif...
متن کاملPhylogeny of some species of Astragalus (Fabaceae) based on morphological data
The phylogenetic relationships among 39 species belonging to 12 sections of Astragalus from Iran were studied on the basis of 29 morphological characters. The cladistics analysis of the morphological data was performed using PAUP* 4.0b10 program. The obtained data were compared with the molecular systematics data obtained from nuclear DNA ITS. In contrast with previous molecular systematic stud...
