“…The endosperm has a uniseriate epidermis, and within the inner layer, there are cells with large numbers of starch granules, calcium oxalate crystals grouped to form drusen, and oil ducts throughout the endosperm (Figure 3 B to D). According to Felippi et al (2010) the role of calcium oxalate crystals in the embryo remains unknown. However, differences among the results of several studies suggest that control of the crystallization is influenced by external factors (such as the calcium concentration in the soil).…”

Rhamnidium elaeocarpum Reissek is a species found in forests, especially in riparian forests. This medicinal species is commonly used to reduce itching of the gums in children at the onset of teething and contains several substances responsible for antiulcer activity. The aim of the present study was to describe the external and anatomical features of the seeds, fruits, and developmental stages of seedlings of R. elaeocarpum Reissek. The processing consisted of maceration in sieves to separate the seeds from the waste. To describe the fruit, external details of the pericarp were observed and for the seeds, the external structures of the integument and internal structures of the endosperm and embryonic axis were analyzed. The morphological aspects of the seeds, germination, and seedlings of Rhamnidium elaeocarpum Reissek are homogenous in all phases. The fruit is simple, fleshy, indehiscent, and berry monospermic. The seed is exalbuminous and cream colored, with a thin and rough integument, the presence of tannin content, and an endosperm rich in starch, calcium oxalate crystals, and lipid content. Germination is hypogeal, and the seedling is cryptocotyledonary Key words: Morphological aspects, germination, post-seminal development, Rhamnaceae ResumoO Rhamnidium elaeocarpum Reissek é uma espécie encontrada em formações florestais, especialmente em matas ciliares, sendo uma planta medicinal com properiedades antiúlcerativas e utilizada para reduzir o prurido das gengivas de crianças no início da dentição e. No presente trabalho, objetivouse a descrição morfo-anatômica do fruto, da semente e das plântulas de R. elaeocarpum Reissek. O beneficiamento consistiu da maceração dos frutos em peneira, separando as sementes dos resíduos. Para a descrição dos frutos foram observados detalhes externos do pericarpo e para as sementes foram analisadas as estruturas externas do tegumento e internas do endosperma e do eixo embrionário. Os aspectos morfológicos das sementes, germinação, e plântulas de Rhamnidium elaeocarpum Reissek são homogêneas em todas as fases. O fruto é simples, carnudo, indeiscente, do tipo baga monospérmica. A semente é exalbuminosa de coloração creme, com tegumento fino. No endosperma foi detectada a presença de taninos, grânulos de amido, cristais de oxalato de cálcio, e lípidos. A germinação é hipógea criptocotiledonar. Palavras-chave: Morfologia, germinação, desenvolvimento pós-seminal, Rhamnaceae
