Obdiplostemony: the Occurrence of a Transitional Stage Linking Robust Flower Configurations

In this paper we review the definition and occurrence of obdiplostemony, and analyse how the condition has impacted on floral diversification and species evolution. Key Results Obdiplostemony represents an amalgamation of at least five different floral developmental pathways, all of them leading to the external positioning of the alternisepalous stamen whorl within a two-whorled androe- cium. In secondary obdiplostemony the antesepalous stamens arise before the alternisepalous stamens. The position of alternisepalous stamens at maturity is more external due to subtle shifts of stamens linked to a weakening of the alternisepalous sector including stamen and petal (type I), alternisepalous stamens arising de facto externally of antesepalous stamens (type II) or alternisepalous stamens shifting outside due to the sterilization of antesepalous sta- mens (type III: Sapotaceae). -

This species is morphologically similar to O. verticillata, but can be easily distinguished by its white flowers and the inflorescences cauliflorous or emerging from short and patent branches on the stem. The new species is endemic to a single locality in the central region of Espírito Santo, in the Brazilian Atlantic Forest, and according to the criteria of the IUCN Red List of endangered plant species, it is regarded as “vulnerable”. Key words: Brazil, endemism, Espírito Santo, new species, taxonomy Introduction The pantropical plant family Ochnaceae represents one of the well-supported subclades of the large order Malpighiales retrieved so far in molecular phylogenetic studies, which agrees with floral morphology, anatomy and histology (Matthews et al. 2012). The center of diversity of the family in the Neotropics is in the Amazon Basin, with some genera exclusive to this phytogeographic domain, and with a few with extra-Amazonian distributions, being restricted to the Andean Forests or to the Brazilian Cerrado and Atlantic Forest (Fiaschi et al. -

Notes on the Taxonomy and Distribution of the Ochnaceae in the Greater Antilles
Willdenowia 36 – 2006 455 ROSALINA BERAZAÍN ITURRALDE Notes on the taxonomy and distribution of the Ochnaceae in the Greater Antilles Abstract Berazaín Iturralde, R.: Notes on the taxonomy and distribution of the Ochnaceae in the Greater Antil- les. – Willdenowia 36 (Special Issue): 455-461. – ISSN 0511-9618; © 2006 BGBM Berlin-Dahlem. doi:10.3372/wi.36.36143 (available via http://dx.doi.org/) In the Greater Antilles the family Ochnaceae is represented by the genera Sauvagesia and Ouratea. The genus Sauvagesia is represented by S. tenella in Cuba and Hispaniola, S. erecta subsp. erecta in Hispaniola and Puerto Rico and S. erecta subsp. brownei in Cuba and Jamaica. The genus Ouratea comprises: O. agrophylla, O. revoluta, O. elliptica. O. schizostyla, O. xolismifolia, O. ×acunae and O. ×savannarum, all endemic to Cuba; O. striata from Cuba and Puerto Rico; O. nitida from Cuba and Jamaica; O. litoralis, endemic to Puerto Rico; O. ilicifolia, endemic to Hispaniola; and O. laurifolia, O. jamaicensis and O. elegans, all endemic to Jamaica. Identification keys to the genera and species are presented. Key words: plant systematics, Caribbean, biogeography, endemism, identification keys. Introduction The family Ochnaceae DC., with 26 genera, is widespread in the tropics and subtropics (Brum- mitt 1992). In the Greater Antilles it is represented by the two genera Sauvagesia L. and Ouratea Aubl. The following regional floras are available: Cuba (Alain 1953), La Española [= Hispaniola] (Alain 1985), Puerto Rico (Alain 1994) and Jamaica (Fawcett & Rendle 1926, Adams 1972). More details about the species can be found in the monographs by Dwyer (1945) and Sastre (1971a-b). -

There is little doubt that the family ofthe Ochnaceae represents a natural one among the more primitive in the Guttiferales (= Clusiales or Theales s. l.). Nonetheless, there are striking differences between the genera, even at first sight. It is not difficult to arrange them in a few distinct, supra-generic taxa. A supposed natural system, as far as relevant to the Malesian genera, is as follows: Subfamily Ochnoideae Tribe OCHNEAE ....................... Subtribe Ochninae 1. Ochna 2.

Couy-Melo and Igor Ballego-Campos * Departamento de Botânica, Instituto de Ciências Biológicas, Universidade Federal de Minas Gerais, Belo Horizonte 31270-901, MG, Brazil; [email protected] (E.A.S.P.); [email protected] (G.A.C.-M.) * Correspondence: [email protected] Abstract: Buds usually possess mechanical or chemical protection and may also have secretory structures. We discovered an intricate secretory system in Ouratea castaneifolia (Ochnaceae) related to the protection of buds and young leaves. We studied this system, focusing on the distribution, morphology, histochemistry, and ultrastructure of glands during sprouting. Samples of buds and leaves were processed following the usual procedures for light and electron microscopy. Overlapping bud scales protect dormant buds, and each young leaf is covered with a pair of stipules. Stipules and scales possess a resin gland, while the former also possess an extrafloral nectary. Despite their distinct secretions, these glands are similar and comprise secreting palisade epidermis. Young leaves also possess marginal colleters. All the studied glands shared some structural traits, including palisade secretory epidermis and the absence of stomata. Secretory activity is carried out by epidermal cells. Functionally, the activity of these glands is synchronous with the young and vulnerable stage of vegetative organs. This is the first report of colleters and resin glands for O. castaneifolia. We found Citation: Paiva, E.A.S.; Couy-Melo, evidence that these glands are correlated with protection against herbivores and/or abiotic agents G.A.; Ballego-Campos, I. -
