“…Em P. actinia (Kurtz et al 2003) foi observada uma cutícula relativamente delgada, levemente estriada e com cera epicuticular com aspecto de escamas. A ornamentação cuticular pode ser um importante caráter taxonômico, podendo ser utilizada para a identificação e delimitação de espécies (Solereder 1908;Metcalfe & Chalk 1979;Cutter 1986;Metcalfe & Chalk 1988;Fahn 1990;Fontenelle et al 1994;Barthlott et al 1998;Kocsis et al 2004;Gomes et al 2005;Moraes 2005;Moraes et al 2009;Arruda et al 2010;Alexandrino et al 2011;Moraes et al 2011;Luna et al 2013). A utilização de materiais herborizados no presente estudo, restringe as possibilidades de maiores especulações sobre os aspéctos ecológicos associado a esta característica.…”

ResumoPassifloraceae possui 17 gêneros e cerca de 750 espécies. O gênero Passiflora, possui aproximadamente 525 espécies, distribuídas nas regiões tropicais do Novo Mundo, Ásia e Austrália, e está subdividido em quatro subgêneros: Astrophea, Decaloba, Passiflora e Deidamioides. Este trabalho teve por objetivo verificar a ocorrência de caracteres diagnósticos e fornecer subsídios para a taxonomia do grupo. Para tanto, foram analisadas oito espécies: Passiflora capsularis, Passiflora misera, Passiflora morifolia, Passiflora organensis, Passiflora pohlii, Passiflora suberosa, Passiflora tricuspis e Passiflora vespertilio. Foram estudados de três a seis indivíduos de cada espécie, obtidos a partir das coleções herborizadas dos herbários do Departamento de Botânica da UFPR (UPCB) e do Museu Botânico Municipal (MBM), ambos em Curitiba-PR. Para o estudo anatômico, as amostras foliares foram submetidas ao processo de reidratação e, posteriormente, incluidas em historesina seguindo técnicas usuais utilizadas em anatomia vegetal. Alguns caracteres se destacaram com valor taxonômico e com potencial uso em estudos filogenéticos, como a presença de papilas epidérmicas, cutícula ornamentada e sistema vascular em arco. Os resultados indicam que estudos mais detalhados sobre a estrutura das papilas epidérmicas e dos tipos de tricomas tectores trarão mais informações para o entendimento das relações em Decaloba e os outros subgenêros. Palavras-chave: estruturas secretoras, folha, papilas, taxonomia. AbstractPassifloraceae comprises 17 genera and approximately 750 species. The genus Passiflora has about 525 species distributed in tropical regions of the New World, Asia and Australia. Passiflora is subdivided in four subgenera: Astrophea, Decaloba, Passiflora, Deidamioides. The goal of this work is to verify the utility of selected anatomical features as diagnose or taxonomical characters. Three to six individuals of eight species of Passiflora, subgenus Decaloba were used: Passiflora capsularis, Passiflora misera, Passiflora morifolia, Passiflora organensis, Passiflora pohlii, Passiflora suberosa, Passiflora tricuspis and Passiflora vespertilio. Samples were obtained from Herbarium collections of the Herbarium of the Departamento de Botânica da Universidade Federal do Paraná (UPCB) and Museu Botânico Municipal (MBM), Curitiba-PR. For the anatomical study, leaf samples were embedded in Historesin following usual anatomical procedures. Some features can be highlighted as taxonomic useful, and of potential use in phylogenetic studies, such as ornamented cuticle, presence of epidermal papillae and the shape of central vascular system. Results have indicated that detailed studies of papillae structure and types of trichomes might bring additional relevant information for the better understanding of the relations within Decaloba and other subgenera.

“…Berdasarkan Tabel 2 dapat diketahui bahwa jenis yang memiliki tipe stomata sama belum tentu memiliki bentuk sel epidermis dan tipe dinding antiklinal yang sama (Yang et al 2012;Luna et al 2013;Goncalves et al 2018). Dinding antiklinal pada pengamatan ini diklasifikasikan menjadi empat tipe, yaitu lurus, melengkung, bergelombang, dan berlekuk dengan sel epidermis berbentuk poligonal dan tidak beraturan (Gambar 1e-1g).…”

Keanekaragaman tumbuhan tidak hanya terlihat secara morfologi, tetapi dapat dibedakan pula secara anatomi. Ciri anatomi dapat digunakan sebagai pendukung dan penguat pengklasifikasian jenis tumbuhan. Penelitian ini bertujuan untuk mengetahui ciri anatomi daun yang dapat digunakan sebagai penciri taksonomi dalam suatu tingkatan taksa melalui perwakilan jenis. Jenis yang digunakan berjumlah 15, yang merupakan perwakilan dari 12 suku tumbuhan berbunga Indonesia. Metode parafin digunakan untuk mendapatkan penampang transversal dan metode perendaman dengan asam nitrit (HNO3) digunakan untuk mendapatkan penampang epidermis daun. Sebagian ciri anatomi pada penelitian dapat digunakan sebagai penciri suku hingga jenis. Hasil penelitian menunjukkan bahwa 15 jenis yang diamati memiliki kesamaan ciri anatomi dengan data penelitian terdahulu yang telah dilakukan baik pada tingkat suku, marga maupun jenis. Kesamaan ciri anatomi tersebut mencakup satu hingga beberapa ciri seperti tipe stomata, dinding antiklinal sel epidermis, jaringan mesofil, dan berkas pengangkut (tangkai daun dan tulang tengah daun). Kesamaan ciri yang didapatkan pada masing-masing jenis menunjukkan bahwa ciri pada struktur anatomi daun dapat menjadi bukti pembatasan takson pada tumbuhan berbunga.

“…Such features are also helpful in phylogenetic analyses based on mixed molecular, morphological, and anatomical data (Källersjö et al 2000;Källersjö and Ståhl 2003;Lens et al 2005;Luna et al 2013Luna et al , 2014Luna et al , 2017Luna et al , 2018Luna et al , 2019. Although fruits and seeds of Primulaceae species, including both herbaceous (Primuloidae and Myrsinoidae) and woody plants (Myrsinoidae and Theophrastoidae), have been examined according to their development, morphology, and anatomy, the obtained results were rather ambiguous regarding systematics and phylogeny of the studied plants (Otegui et al 1998b;Otegui and Cocucci 1999;Anderberg et al 2007;Oh et al 2008;Morozowska et al 2011).…”

Comparative micromorphology and anatomy of seeds and endocarps of selected Primulaceae and their systematic implications

et al. 2020

Seed and endocarp micromorphology and anatomy of 16 taxa from the genera Ardisia, Geissanthus, Stylogyne, Myrsine (Myrsinoideae), and Jacquinia (Theophrastoideae) were examined using stereo-and scanning electron microscopy and discussed in the light of the current phylogenetic framework. In all species, the ornamentation of the seed surface was reticulate, tuberculate, or tuberculate-colliculate with several differences concerning the cell outline and anticlinal cell wall boundaries. For seeds of almost all Myrsinoideae species, one-layered seed coat devoid of rhomboid or prismatic crystals was characteristic, while seeds of J. armillaris had a two-layered seed coat with prismatic crystals. The one-layered seed coat in Myrsinoideae may be considered a synapomorphy of this subfamily. The endosperm tissue in seeds of Myrsinoideae was differentiated into two types. Seeds of Ardisia and Geissanthus species were characterized by 'pitted' endosperm, while in seeds of Myrsine species both the 'pitted' endosperm and endosperm with evenly thickened cell walls were present. In seeds of Theophrastoideae, the endosperm was 'pitted.' Our results confirmed that the concave hilum area is characteristic of subglobose seeds of Myrsinoideae. The ruminate endosperm was present in all the examined Myrsine species, but it was absent in Ardisia crenata, Geissanthus ambiguus, and Stylogyne pauciflora seeds. Thus, the ruminate endosperm is not the feature clearly distinguishing the seeds of Myrsinoideae and Theophrastoideae. Endocarps of Myrsinoideae vary in terms of their morphology and anatomy. The variation within the primary and secondary sculpture of their inner surface and the presence of stomata in endocarps of particular species may have systematic implications.
