| Distyly is a genetically controlled floral dimorphism, characterized by the reciprocal positioning of pin and thrum morphs, a heteromorphic incompatibility system and a balanced morph ratio (isoplethy). This study aimed to investigate the phenology, features of distyly, reproductive biology, and floral visitors of Psychotria goyazensis Mull. Arg. (Rubiaceae), an intramorph self-compatible species, in a tropical semideciduous forest in the municipality of Catalão, located in the state of Goiás, Brazil. The phenology was recorded for a sample of individuals, the floral morphology being described using fresh and fixed material. The incompatibility system was tested using controlled hand pollinations. Floral visitors were collected and identified. Blooming... |

| ABSTRACT Angiosperms display an enormous diversity of forms, functions and strategies when it comes to reproduction. This multiplicity has been translated into several terminological concepts and contexts, which have facilitated further research. On the other hand, the use of terms that address the reproduction of flowering plants has been shown to be inconsistent in the literature, complicating communication among specialists. Key terms, such as “reproductive system”, “mating system” and “sexual system”, among others, have been frequently cited as synonyms, and even used in different circumstances. This review proposes to establish a consistent nomenclatural classification in the field of angiosperms reproductive biology in order to facilitate... |

| A heterostilia é um polimorfismo floral geralmente associado a sistemas genéticos de intramorfo incompatibilidade. Nós avaliamos aspectos reprodutivos da heterostilia de uma população de Rourea induta Planch. em uma área de cerrado de Brasília, DF. Foram conduzidos estudos sobre sua biologia floral, sistema reprodutivo, produção e maturação de frutos, germinação de sementes, fenologia reprodutiva e visitantes florais. As flores são pequenas (11 mm de diâmetro), com morfologia simples e possuem dois grupos de cinco estames de comprimentos diferentes e cinco pistilos. O comprimento médio de estames e pistilos diferiu significativamente entre o morfo brevistilo e o longistilo. No entanto, não houve hercogamia recíproca completa entre os dois morfos florais.... |
