Abstrak : Tumbuhan paku  (Pteridofita) epifit banyak di jumpai di kawasan Universitas Riau. Karakteristik spora pada tumbuhn apaku memegang peranan penting dalam kajian taksonomi. Penelitian ini bertujuan untuk mengidentifikasi jenis-jenis pteridofita epifit di kawasan ini dan  mengkarakterisasi sporanya. Metode pengambilan sampel dilakukan menggunakan metode eksplorasi. Setiap jenis yang dijumpai didokumentasikan, dibuat herbarium, dideskripsi dan diidentifikasi. Spora dikoleksi dari daun yang sudah dewasa dan dibuat preparat menggunakan metode asetolisis. Preparat spora diamati dan didokumentasikan menggunakan mikroskop digital. Data yang diperoleh kemudian disajikan dalam bentuk gambar dan tabel serta dianalisis secara deskriptif. Hasil inventarisasi paku epifit di kawasan Universitas Riau mengidentifikasi 18 jenis paku epifit, yang tergolong ke dalam 6 famili yaitu Aspleniaceae, Davalliaceae, Nephrolepidaceae, Polypodiaceae Pteridaceae and Thelypteridaceae. Namun kajian palinologi hanya dilakukan pada 11 jenis yang sudah menghasilkan spora. Hasil pengamatan spora menunjukan bahwa semua jenis paku epifit mempunyai tipe dasar spora monolete, berbentuk ginjal dan hanya mempunyai satu laesura pada bagian ventral. Ukuran spora yang dijumpai adalah besar dan sangat besar, dengan ornamentasi permukaan Lohpat, verukat berpapila verukat, tuberkulat, ekinat pendek dan ekinat panjang. Morfologi spora yang ditemukan pada penelitian ini menunjukan karakteristik yang berbeda pada setiap jenis. Namun masih perlu dilanjutkan pengamatan menggunakan Scanning Electron Microscopy untuk mendapatkan oramentasi lebih detilKata kunci : paku epifit, palinologi, spora, monolete, UNRI Abstract : Ephypitic ferns are commonly found in University of Riau area. Spore characteristics play important role in taxonomical words. This study aimed to identify ephypitic pteridophyte species from this area and characterize their spore. Samples were collected using exploration method, and were then documented, prepared for herbarium, described and identified. Spore grains were collected from mature leaves and prepared by using acetolysis method. The spores were then observed and documented using digital microscope. Data were presented in figures and tables and describtively analized. The inventory of ephypitic ferns from University of Riau area identified a total of 18 fern species belong to 6 families, i.e. Aspleniaceae, Davalliaceae, Nephrolepidaceae, Polypodiaceae, Pteridaceae and Thelypteridaceae. Palinologycal study had been carried out from 11 species that produced spore. We observed the basic spore type of examined ephypitic ferns, monolete, with reniform shape and one laesura at the ventral part. The size of spore observed were big and very big spore, with surface ornamentation Lohpate, papillous verucate,  verucate,  tuberculate,, short echinate and long echinate. Spore morphology observed in this study showed the characteristic among the examined species. The further study using Scanning Electron Microscopy is neccesary to obtain detail spore ornamentation.Keywords: ephypitic fern, palynology, spore, monolete, UNRI

Abstract. Sofiyanti N, Isda MN, Juliantari E, Pranata S, Suriatno R. 2019. The inventory and spore morphology of ferns from Bengkalis Island, Riau Province, Indonesia. Biodiversitas 20: 3223-3236. Bengkalis Island is one of main islands at coastal region of Riau Province, Indonesia. The first fern inventory had been conducted on this island, to identify the fern checklist as well as examined the morphology of their spores. Samples were collected from 2 subdistricts and 12 study sites, using exploration method. The spore specimens were coated using AU, before observation using Scanning Electron Microscopy (SEM). A total of 22 fern species are recorded from Bengkalis Islands. These species belong to 3 orders, i.e. Gleicheniales (1 species), Polypodiales (20 species) and Schizaeales (1 species). The spore characteristic indicated similar unity of spore, i.e. monad spore, with triangular, subtriangular, tetrahedral and reniform shape. Three basic types of spore have been observed, i.e. monolete, dilete, and trilete. The spore class observed in this study are small (22 ± 0.88 µm), medium (27.35 ± 1.45 to 47.85 ± 0.88 µm) and large (51.34 ± 1.83 to 53.8 ± 1.81 µm). The ornamentation of perisphore is the main character to distinguished species within one genus.

A new interspecific hybrid in Isoetes, I. maritima Underw. × I. howellii Engelm., is delineated and described from the Shuswap Highlands region of British Columbia by means of cytology and scanning electron microscopy of spores. Isoetes × marensis D.M. Britton and D.F. Brunton, hyb.nov. is the name proposed for this taxon. It is triploid (3x; 2n = 33) and is believed to produce only sterile and (or) aborted spores. Hybrid plants have polymorphic spores that demonstrate size and surface ornamentation features intermediate between those of the putative parents. Three populations were examined, each growing with both of the putative parents in silt and sand among granite cobble over clay along an emergent lakeshore. Isoetes × marensis is the first described North American hybrid involving an amphibious Isoetes. It is expected to be a rare taxon owing to the restricted sympatric area of the putative parents and their tendency to occupy different habitats. Key words: Isoetes, Isoetes howellii, Isoetes maritima, hybrid, British Columbia.

A comprehensive study based on seed morphology of perennial Euphorbia (Euphorbiaceae) sect. Pithyusa species occurring in Turkey is presented. A total of 14 species were studied. Seed characteristics were examined using scanning electron microscopy (SEM) as well as dissecting light microscopy. Significant features are: seed size, seed shape, shape of caruncle and seed surface ornamentation. Three different seed surface types (smooth, pitted, and wrinkled) were observed. Four main seed shapes (ovoid, oblong, quadrangular, and globose), as well as seven types of seed coat ornamentation (reticulate-areolate, areolate, alveolate, falsifoveate, pusticulate, colliculate and smooth) were found. The number of testa cells per 100 µm2 and also its range, from 8–12 to 57–63, are given.

Coleosporium plumeriae Pat. is a rust fungus (Melampsoraceae) found on Plumeria species. The spermagonial and aecial states are unknown. Light and scanning electron microscopy of uredinia have revealed catenulate, verrucose urediniospores with scattered germ pores. We expect that, as in other Coleosporium species, the urediniospores are morphologically similar to aeciospores. The urediniospore ornamentation consists of distinctive, annulate, bluntly capitate tubercles. Light microscopy of telia indicates that teliospores are smooth, gelatinous, and one celled, quickly appearing four celled with division of the protoplast into an internal four-celled basidium.

In this work, spore morphology of eight species, Tortula muralis, Tortula brevissima, Aloina brevirostris, Syntrichia leavipila, Microbryum clavallianum (Pottiaceae); Funaria hygrometrica, Entosthodon muhlenbergii, Entosthodon attenuates (Funariaceae); were examined by Light microscopy (LM) and Scanning electron microscopy (SEM). All spores are small; the length of polar axis is between 7.5 ?m and 18.5 ?m, equatorial diameter is between 10.5 ?m and 27 ?m. The smallest spores of them are Tortula brevissima and the biggest spores of them are Entosthodon attenuates. The shapes of the spores are determined as suboblate for Tortula muralis, Aloina brevirostris, Syntrichia leavipila, and oblate for Tortula brevissima, Funaria muhlenbergii, Funaria hygrometrica, Entosthodon attenuates. The ornamentation observed can be regulate, verrucate- regulate, baculate, verrucate, clavate- foveolate, clavate, foveolate- psilate on the distal pole, spore ornamentation of the proximal face is different or less complex than the distal face. We can concluded that the spore ultrastructure give important role for identification and taxonomic significant.

The currents study evaluated the morphology (apperture, size, perine structures and surface ornamentation) of treated spores of 45 selected fern species from the Western Ghats of India, using Scanning Electron Microspcopy (SEM). Twenty-six species of fern spores were trilete type, while 19 of them had monolete aperture types. The size of the spore were found to be highly variable (20X20µm to 60X60µm) with an average mean spore size of 44 µmX38µm. Further more the spores were found to have a highly diverse perine ornementaion with 11 different types of perine structures. Gammate and psilatetype of perine ornamentation,and Globose and ellipsoidal spore shape were found to be the most common within the studies fern spore samples.The variability found in the spore ultra structure and perispore ornamentation of the selected pteridophytes species reflects the morphological differences observed in the sporophyte. The spores could be an important source of characteristics with systematic value in fern taxonomy.The spore morphology of the examined pteridophytes studied common, endemicor otherwise will find a significant role in future taxonomic surveys, and other morphology, Palynology, discrimination, and identification studies of pteridophytesin the Western Ghats.

Taxonomy of the Myxomyoetes has been based primarily on morphological characteristics observed in the light microscope. Although the fruiting stage is sensitive to environmental conditions, most species exhibit a distinctive although variable category, and thus characteristics of this stage have been used for morphological differentiation. There has been and still is, however, much disagreement concerning the classification and relationships between members of this group. Although capillitial and spore morphology are used in taxonomic classifications, because of their small dimensions they are often poorly defined or not visible in the light microscope. These characteristics are easily discernible by surface scanning electron microscopy (SEM). The purpose of this initial study was to investigate appropriate sample preparations and determine if taxonomically valuable information could be provided with the use of SEM.

Fruits and seeds of Cynoglossum creticum Miller, C. officinale L., C. montanum L. and C. glochidiatum Wallich) distributed in the Middle and East Black Sea Region in Turkey were studied by scanning electron microscopy. Some differences were found in seed coats and fruit surfaces. SEM observations of fruit surface were focused on surface ornamentation and glochids. Two types (tuberculate and granulate) and two subtypes (granulate - punctuate and granulate - tuberculate) were observed among the species. Reticulate type of seed coat and detailed subtypes of reticulate types were determined on the basis of ornamentation of the seed coats.     Key words: Cynoglossum, Fruit surface, Seedcoat, SEM, Micromorphology, Boraginaceae doi:10.3329/bjb.v37i2.1716 Bangladesh J.
