“…Th is anatomical aspect was very clear, even without complete ontogenic studies in the older descriptions such as those of Cordemoy (1911), Sprecher (1919), Rao & Kothagoda (1984), and Corner (1976), as well as in the more detailed studies undertaken by Mourão & Beltrati (1995a,b;2000;2001), Marzinek (2009), andCampana et al (2010) as well as in the present work.…”

Garcinia gardneriana (Clusiaceae) is a small to medium-sized tree that usually occurs on the floodplains of the Paraná River and it is an important food source for the local inhabitants. The fruit itself is consumed in natura, and juices and sweets are made from it. The purpose of this study was to describe morphological and structural aspects of fruits and seeds of this species in order to classify the fruit type and the pulpy layer which involves the seeds. The material analyzed consisted of ovary and fruits in different stages of development, collected from five plants from Aurélio Island, Baía River (MS, BR) and the description was done according to standard procedures in anatomy. The fruit is a yellowish-orange spherical berry ("bacóide" type). The smooth, coriaceous skin consists of the lignified exocarp. The endocarp cell layers are derived from the activity of an adaxial meristem that undergoes radial elongation. The edible sweet white pulp is formed by the endocarp, as well as the spongy mesocarp, in which the secretory ducts lose their function. The unitegmic anatropous ovules develop into anatropous exalbuminous seeds with a collapsed and undifferentiated testa. The embryo is hypocotylar. The features here described generally occur in Clusioideae-Garcinieae and Symphonieae.

“…ex Willd. (Mourão & Marzinek 2009) and it is the inner epidermis of the inner integument in all species mentioned. In Garcinia gardneriana the endothelium is located in inner epidermis of the single integument and it is most similar to this layer described by Mourão & Beltrati (1995a) for P. insignis in the inner integument.…”

“…Likewise, the hypocotilar embryo was previously attributed to Garcinia plants (NASCIMENTO; CARVALHO; MÜLLER, 2002) and to other Clusiaceae genera such as Plantonia (MOURÃO; BELTRATI, 1995) and Clusia (MOURÃO; MARZINEK, 2009). According to Mourão and Marzinek (2009), rudimentary cotyledons are also found in Clusia embryos and, according to Asinelli, Souza and Mourão (2011), in Garcinia gardneriana embryos. Therefore, the hypocotilar embryo, showing rudimentary cotyledons, as found in G. brasiliensis, is very similar to many Clusiaceae embryos, confirming an apomorphy of the group.…”

“…Despite the importance of anatomical studies in the Clusiaceae family, there have still been few studies of the anatomies of these species. Mourão and Marzinek (2009) reported the importance of anatomy for the Garcinia phylogeny but there is a lack of information for a large number of species. As there is no information in the literature about G. brasiliensis anatomy, the goal of this work is to evaluate the anatomy of the embryo, stem, leaves, and roots of G. brasiliensis.…”

Studies concerning the structure of plant embryos are very important in different areas of study such as plant systematics and evolution or the handling of native species. This work aims at evaluating the anatomy of the embryo and vegetative organs of Garcinia brasiliensis in order contribute to taxonomical, ecological, handling studies of this species. Some seeds were stored for anatomical analysis of the embryo and some were germinated to obtain young plants for anatomical analysis of the vegetative organs. Plants were cultivated in growth chamber for 120 d. Seeds and young plants were both fixed in a solution of formaldehyde, acetic acid, and 70% ethanol and usual plant microtechnique methods were employed. Slides were photomicrographed and a quantitative analysis of tissues was performed using UTHSCSA-Imagetool software. Histochemical analysis was performed for the detection of starch, lipids, alkaloids, and phenolic compounds. The G. brasiliensis embryo has rudimentary cotyledons and the reserves are stored in the hypocotyl-radicle axis. Most of the reserves are starch grains, stored in ground meristem cells, which contain a few oleossomes and alkaloids in the cell walls. The young plant leaves show dorsiventral and hypostomatous properties, including a one-seriated epidermis and a thick cuticle. In the midrib vascular bundle, the phloem is organized around the xylem vessels. The primary stem has a one-seriated epidermis and angular collenchyma. Adventitious roots are polyarch and show a one-seriated epidermis and endodermis. The anatomy of embryos and young plants of G. brasiliensis is similar to that of other Clusiaceae species. RESUMO: Estudos sobre a estrutura do embrião são de enorme importância para diferentes áreas, como a sistemática, a evolução e o manejo de espécies nativas. Portanto, o objetivo deste trabalho foi avaliar a anatomia do embrião e de órgãos vegetativos das plântulas de Garcinia brasiliensis. Sementes foram reservadas para realização das análises anatômicas do embrião e outras foram postas para germinar, para obtenção das plantas visando à análise de folhas, caules e raízes. As plantas foram cultivadas em sala de crescimento por 120 dias. Sementes e plantas foram fixadas em uma solucion de formaldeído, ácido acético e etanol a 70% e submetidas a procedimentos usuais de microtécnica vegetal. As lâminas foram fotomicrografadas e a análise quantitativa dos tecidos foi realizada no software UTHSCSA-Imagetool. Análises histoquímicas foram realizadas para detecção de amido, lipídeos, alcalóides e compostos fenólicos. O embrião de G. brasiliensis possui cotilédones pouco desenvolvidos, sendo a reserva das sementes localizada no eixo hipocótilo-radicular. As reservas são compostas principalmente de amido, localizado nas células do meristema fundamental. Há um pequeno número de oleossomos nas células do meristema fundamental e suas paredes celulares contêm alcalóides. A folha das plantas é dorsiventral e hipoestomática, com epiderme unisseriada e cutícula espessa. No feixe vascular da nervura ...

RESUMO. Clusia lanceolata Cambess é espécie arbustiva da Mata Atlântica. Caracteriza-se por ser dioica, com flores estaminadas e pistiladas grandes, vistosas, de coloração rosa, apresentando a parte interna vinácea. Foram descritos aspectos morfológicos e estruturais dos frutos e sementes dessa espécie, visando classificar corretamente o seu tipo de fruto e, também, confirmar a origem do apêndice carnoso que envolve as sementes. O material botânico utilizado constou de flores em antese e frutos, em quatro estádios de desenvolvimento, coletados de dois espécimes. Os estudos morfológicos e anatômicos foram realizados segundo técnicas usuais. O fruto é cápsula septífraga, esférica, de coloração verde-avermelhado. O exocarpo é unisseriado; o mesocarpo parenquimático contém numerosos ductos secretores e feixes vasculares, de disposição principalmente longitudinal. O endocarpo é derivado da epiderme interna do ovário e de três a quatro camadas subepidérmicas, cujas células alongam-se tangencialmente e a parede que delimita o lóculo sofre lignificação. A abertura se faz pela sutura carpelar, por meio de uma faixa de células parenquimáticas de tamanho reduzido, que se bifurca em direção aos lóculos no meio dos septos. Os óvulos anátropos bitegumentados, com endotélio e hipóstase, originam sementes também anátropas, exotégmicas e envolvidas por arilo de origem funicular e exostomal. O embrião é hipocotilar.Palavras-chave: Clusioideae, desenvolvimento, estrutura, órgãos reprodutivos.ABSTRACT. Morphology, anatomy and ontogeny of the fruits and seeds of Clusia lanceolata Cambess. (Clusiaceae). Clusia lanceolata Cambess. is a shrub species native to the Atlantic Forest. The plant is dioecious, with large, showy, pink staminate and pistillate flowers that are wine-colored internally. The morphological and structural aspects of the fruits and seeds of this species are described here in order to correctly classify the fruit type and to determine the origin of the fleshy appendage that surrounds the seeds. The botanical material utilized here contained flowers in anthesis and fruits in four stages of development, and were collected from two different plants. The morphological and anatomical studies were performed according to traditional techniques. The fruit is a septifrage, spherical capsule with a reddish-green coloration. The exocarp is uniseriate; the parenchymatous mesocarp contains numerous secretory ducts and vascular bundles arranged in predominantly longitudinal positions. The endocarp is derived from the internal epidermis of the ovary and has from three to four subepidermal layers whose component cells are tangentially elongated, and the cell walls lining the locule become lignified. The fruits open by means of the carpelar suture, along a stand of small parenchymous cells that bifurcate in the direction of the locules, in the midst of the septum. The anatropous bitegumented ovules, with an endothelium and hypostase, give rise to seeds that are likewise anatropous, exotegmic, and wrapped in an aril that has a funicula...
