1. Atypical distyly in Psychotria goyazensis Mull. Arg. (Rubiaceae), an intramorph self-compatible species
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)

2. Biologia reprodutiva de Guettarda platypoda DC. (Rubiaceae) em uma área de restinga no Estado de Pernambuco
Distyly is a syndrome mainly found in the Rubiaceae family, being characterized by a floral dimorphism in which some individuals have thrum flowers (T) and others have pin ones (P). Typical distylous species present reciprocal hercogamy between floral morphs, a self and intramorph incompatibility mechanism and an equilibrated proportion of morphs in the popu

3. VariaÃÃes florais e heterostilia em Palicourea rigida (Rubiaceae) nos cerrados do Brasil Central / Floral variations and heterostyly in Palicourea rigida H.B.K. (Rubiaceae) in the cerrados of Central Brazil
The distyly is a floral polymorphism controlled genetically, where the populations present individuals with pin flowers, that possess long styles and short stamens, and individuals with thrum flowers, that possess short styles and long stamens. Their populations tend to be isoplethyc and anomalies in the distribution of pin and thrum flowers in the populatio

5. Morph-Specific Proteins in Pollen and Styles of Distylous Turnera (Turneraceae)
We used nondenaturing isoelectric focusing (IEF) in a survey of plants from 11 populations to identify style and pollen proteins unique to the short-styled morph of Turnera scabra, T. subulata and T. krapovickasii. Three protein bands [approximately isoelectric points (pIs) 6.1, 6.3 and 6.5] were found only in styles and stigmas of short-styled plants while
