“…In Parahemionitis cordata, sclerenchymatous cells are arranged in 4-5 layers. while Pteris confusa and Pteris showed 2-3 layers of sclerenchymatous cells (Resmi et al 2016).. 4.E-F) located on the dorsal side. The position vascular bundle is also similar, only one vascular bundle located in the middle of dorsal side.…”

Abstract. Sofiyanti N, Iriani D, Fitmawati. 2019. The first record of grass-like fern, Schizaea dichotoma (L.) J. Sm. (Schizaeaceae) from Lingga Island, Indonesia: Its morphological, anatomical and palynological study. Biodiversitas 20: 2651-2660. Schizaea dichotoma (L.) J.Sm. is one of fern species from Family Schizaeaceae. This species is grass-like, dimorphic with fan-shaped fronds, and well-known with local name Rumput Merak. The first record of this species is reported from Lingga Island, Riau Islands Province, Indonesia. The aim of this study was to examine the morphology, anatomy and spore characteristics of this fern. This study had been carried from June to December 2017. Samples were collected using exploration method, documented, and prepared for herbarium specimen. In this study, we examined the morphological characters, anatomical characters of rhizome, stipes, and pinnae of both fertile and sterile fronds, as well as spore feature. The anatomical preparations were carried out using paraffin method, while spore specimens using acetolysis method. The anatomy of rhizome, stipes, and pinnae, as well as spore characters, were then observed and documented using digital microscope Celeron. S. dichotoma is dimorphic fern with grass-like habit, fan-shaped laminae that repeatedly forked end in sorospore in fertile frond. The rhizome has vascular bundle surrounded by star-shaped sclerenchymatous layer. The cross-section of stipes of both fertile and sterile fronds are "M" shaped with a vascular bundle located in the dorsal side, while the leaves have a vascular bundle in the middle of midrib. The type of vascular bundles and stele of those organs are similar, i.a. collateral closed and protostele. We observed The Casparian strip in the endodermis layer of rhizome, stipes, and leaves, as well as at cortex and among the xylem. The spore of S. dichotoma is monolete and large spore class (ca. 59.5 ± 2.4 x 35.86 ± 2.01 µm).

“…The study of anatomy in fern had been previously reported (Haq 2017;Kotrnon 2007;Resmi et al 2016;Talip et al 2012). In this study we examined the anatomy of the rhizome and stipe.…”

“…However, only limited studies of fern anatomy from this province had been reported on other taxa such as Dicranopteris and Nephrolepis (Sofiyanti et al 2019b), and no report was on the anatomical study of Pyrrosia from Riau Province. The study of anatomical characteristics of rhizome and stipe in ferns had been widely carried on many taxa (Nopun et al 2016;Resmi et al 2016;Sofiyanti et al 2019b;Tian et al 2014). Therefore, this study was aimed to provide the detailed morphological and anatomical characteristics of Pyrrosia from Riau Province.…”

Abstract. Sofiyanti N, Sari AK, Iriani D, Mutrofin R, Taufiq I, Juliantari E, Pranata S. 2021. Morphological and anatomical study of four Pyrrosia (Polypodiaeae) species from Rumbai forest, Riau Province, Indonesia. Biodiversitas 22: 4905-4914. Pyrrosia is one of genera in Polypodiaceae that is commonly distributed at Riau Forest, Indonesia. However, the detailed morphological characteristics and anatomical study of Pyrrosia in this region is scanty. This study was aimed to characterize the morphology and anatomy of four Pyrrosia species (P. angustata, P. lanceolata, P. nipoboloides and P. piloselloides) from Rumbai Forest, Riau Province. All of the specimens were collected in the field. Morphological characters were examined in detail. Anatomical preparation was conducted using the paraffin method. The specimens were then observed and photographed using a light microscope. Principal Component Analysis had been carried out using a total of 52 morphological and anatomical characters. The result showed the morphological variation among the species, especially on the shape of sterile lamina and sori characteristics. Anatomically, the examined species showed variations in outline shape in the transverse section of rhizomes and stipes, schelerenchymatous sheath and strand, as well as number of meristele. The PCA results showed that only three characters (shape of sterile laminae, base of sterile laminae, and upper surface color of sterile laminae) have eigenvalue over 1.00 and together these explain 100% of the total variability of the data. The anatomical data in this study is reported for the first time on Pyrrosia from Riau province.

“…Some Malaysian ferns had been examined their stipe anatomy, such as Gleicheniaceae including Dicranopteris linearis (Yen 2006), Davallia, including Davallia denticulata (Talib et al 2012), Blechnum (Talip et al 2014). While Resmi et al (2016) reported the stipe anatomy of Adiantum, Drynaria, Lygodium, Marsilea, Pityrogramma, and Pteris from South India. In this study, we examined the stipe anatomy of all fern species in this study.…”

Munawaroh E, Yuzammi. 2019. Species diversity of Orchids in Bukit Barisan Selatan National Park, Lampung, Indonesia. Biodiversitas 20: xxxx. Orchids, belonging to the family Orchidaceae, are well known ornamental plants due to their beautiful flowers and varied colors. The members of this family have received more scientific attention than other plant families because of their unique botanical features and economic value. This study was conducted to explore and record the species diversity of Orchidaceae in Sumatera, especially in the Bukit Barisan Selatan National Park (BBSNP), Lampung, Indonesia. This research was carried out from 2011 to 2014 at four locations, namely Kubu Perahu Resort, Sukaraja Atas Resort, Pugung Tampak Resort and Sekincau Resort, using purposive sampling method. A total of 132 species belonging to 52 genera of orchids have been identified from BBSNP, Lampung, of which 37 genera are epiphytic orchids and 15 genera are terrestrial orchids. Two species namely, Vanda sumatrana and Grammatophyllum speciosum, have been recognized as protected species. Vanda sumatrana is also endemic to Sumatera. These orchids are also cultivated at Liwa Botanic Garden, as an ex situ conservation.
