Abstract

Cytological observations have been carried out by several researchers in South China, Japan, Ceylon, Hongkong, Himalaya and Java. The results from various regions showed that P. multifida had a fairly high genetic variation, namely diploid, triploid and tetraploid types. Therefore cytological and reproductive study on P. multifida from its geographical distribution areas need to be done. The objectives of this research were to observe the somatic chromosome number and reproductive type of P. multifida, and to recognize the relationship between morphological variation and its ploidy level as well as stomatal index. Plants were collected from several localities in Bogor. Ploidy level was determined by observing somatic chromosome number by using squash methods. Reproductive type was determined by counting spore number in each sporangium. Morphological characters examined were the stipe, lamina, pinnae, veins, and indusium. Observations of stomata and epidermis of leaves were done by making an incision paradermal leaf. Pteris multifida has two ploidy level and reproduction type, namely apogamous triploid (2n = 87) and sexual tetraploid (2n = 116). The two ploidy levels could not be distinguished based on morphological characteristics, but they can be differentiated by their epidermal cells number. Apogamous triploid has fewer number of epidermal cells, the sexual tetraploid has a greater number of epidermis.

Nina Ratna Djuita, Alex Hartana, Tatik Chikmawati & Dorly. 2016. Distribution of pulasan [Nephelium  ramboutan-ake (Labill.) Leenh] in Java and Relationship of Their Morphology. Floribunda 5(4): 129–138. — Distribution of pulasan in Java is not known yet. The purposes of this study were to provide information about the locations of pulasan trees in Java, and to analyze relationship of this species based on morphological characters. Pulasan exploration was carried out in four provinces in Java encompassed West Java, Central Java, East Java, and Yogyakarta Special Region. Morphological characteristics of pulasan were observed, then the relationships were analyze using NTSys pc 2.02 program.  Result showed that most of pulasan located in West Java, especially in the area of Bogor.  Based on the dendrogram, it was known that the use of ve-getative dan generative characters could distinguish males and hermaphrodite pulasan trees, while the use of vegetative characters only, could not differentiate the type of pulasan trees. Pulasan trees from different areas can be grouped in the same cluster because of the similarity of their morphological traits.Keywords: Kapulasan, morphological characters, dendrogram, Sapindaceae. Nina Ratna Djuita, Alex Hartana, Tatik Chikmawati & Dorly. 2016. Distribusi Kapulasan [Nephelium ramboutan-ake (Labill.) Leenh.] di Pulau Jawa dan Hubungan Kekerabatan Morfologinya. Floribunda 5(4): 129–138. — Persebaran kapulasan di Pulau Jawa belum diketahui dengan pasti.  Penelitian ini bertujuan memberikan informasi tentang lokasi-lokasi yang masih mempunyai pohon kapulasan di Pulau Jawa, dan menganalisis hubungan kekerabatannya berdasarkan ciri morfologi. Eksplorasi kapulasan dilakukan di empat provinsi di Pulau Jawa yaitu Jawa Barat, Jawa Tengah, Jawa Timur, dan Daerah Istimewa Yogyakarta. Tanaman hasil eksplorasi diamati ciri morfologinya, kemudian dianalisis hubungan kekerabatannya dengan menggunakan program NTSys pc 2.02.  Hasil penelitian menunjukkan bahwa sebagian besar kapulasan terdapat di Jawa Barat terutama di daerah Bogor. Berdasarkan dendrogram yang dihasilkan, diketahui bahwa penggunaan ciri  vegetatif dan generatif dapat membedakan kapulasan jantan dan hermafrodit, sedangkan penggunaan ciri  vegetatif saja, tidak dapat membedakan kedua tipe tanaman tersebut. Tanaman kapulasan dari daerah yang berbeda dapat mengelompok dalam satu grup yang sama karena adanya keserupaan dalam ciri-ciri morfologinya.Kata kunci: Kapulasan, karakter morfologi, dendrogram, Sapindaceae.

Floribunda 5(6): 192–199. —  Rambutan belongs to the Sapindaceae family that has closely related to longan and lychee. The observation on leaf anatomy of rambutan, longan, and lychee was conducted to provide information about leaf anatomy of Sapindaceae’s members. The anatomical features of leaf paradermal and transversal sections were examinated on four varieties of rambutan namely binjai, rapiah, sikoneng, and aceh lengkeng; and two closely related families, longan and lychee. All rambutan cultivars and lychee had the same stomata type: cyclocytic, while stomata in longan was surrounded by six subsidiary cells. Epidermal cells of rambutan and lychee leaves have polygonal shape with flat side, whereas epidermal cell of longan has polygonal shapes with notched. Based on transversal sections, rambutan, longan, and lychee have bifacial type, but they are differed in the number of palisade layer and the shape of palisade cellls. Leaf anatomical characters could be used to distinguish between rambutan and its closed relatives, longan and lychee; but it could not be used to differentiate among rambutan’s cultivars.Keywords: longan, lychee, rambutan, Sapindaceae, stomata type.Qothrunnada Sungkar, Tatik Chikmawati & Nina Ratna Djuita. 2017. Anatomi Daun Rambutan  (Nephelium lappaceum L.) dan Kerabatnya. Floribunda 5(6): 192–199. —  Rambutan merupakan tumbuhan yang termasuk ke dalam suku Sapindaceae dan masih berkerabat dekat dengan lengkeng dan leci. Pengamatan tentang anatomi daun Sapindaceae masih jarang dilakukan, sehingga penelitian ini perlu dilakukan untuk memberikan informasi mengenai anatomi daun beberapa anggota Sapindaceae. Pengamatan ciri anatomi dari sayatan paradermal dan transversal dilakukan terhadap empat kultivar rambutan yaitu rambutan binjai, rapiah, sikoneng, dan aceh lengkeng, serta dua kerabat dekatnya yaitu lengkeng dan leci. Hasil sayatan paradermal memperlihatkan bahwa stomata tidak ditemukan di permukaan atas daun rambutan, lengkeng, dan leci. Stomata pada daun rambutan dan leci adalah stomata dengan tipe siklositik, sedangkan stomata pada lengkeng dikelilingi oleh enam sel tetangga. Epidermis pada daun rambutan dan leci berbentuk poligonal dengan sisi rata, sedangkan sel epidermis pada daun lengkeng berbentuk poligonal dengan sisi berlekuk. Sayatan transversal  memperlihatkan bahwa daun rambutan, lengkeng, dan leci bertipe bifasial. Ketiga jenis berbeda pada jumlah lapisan palisade dan bentuk sel palisade. Ciri anatomi daun dapat digunakan untuk membedakan rambutan dari kerabat dekatnya, leci dan lengkeng; tetapi tidak dapat digunakan untuk membedakan antara kultivar rambutan.Kata kunci: lengkeng, leci, rambutan, Sapindaceae, tipe stomata.

Abstract

Since researchs on diversity of epiphytic Bryophytes are more common observed on Angiospermae than those on Gymnospermae, this study was conducted to observe diversity of epiphytic Bryophytes on Gymnospermae in BBG. The Bryophytes samples were collected from Gymnosperms trees in Blok I which is Cycadaceae familly and those in Blok II which are the familly of Pinaceae, Araucariaceae, Gnetaceae dan Podocarpaceae. Only the trees have diameter ≥ 20 cm of trunk were sampled. Bryophytes were collected from the trunk base at 0–200 cm above the ground, at four cardinal direction (north, south, west, and east). In total 18 species of epiphytic Bryophytes were found, included 12 genera and 7 families. The family which had the highest number of species was Lejeuneaceae. The most common species on Gymnosperm trees in the Botanical Garden were Lejeunea tuberculosa and Octoblepharum albidum. Both of them were found at 6 trees of 13 total tree samples. The species were found more frequently at west (2,1%) and north (1,8%) part than east and south part of the host trees. They more frequently inhabit the trunk base on 0–100 cm than 100–200 cm.
