THE RARE PTERIDOPHYTES OF MT. SLAMET WITH THREE SPECIES NEW RECORDS FOR JAVA Titien Ngatinem Praptosuwiryo
Floribunda Vol. 4 No. 6 (2013)
Publisher : PTTI

It is estimated that Java has about 500 species of Pteridophytes. Nevertheless conservation status of the Pteridophytes in Java has not been provided yet. Therefore inventory on the Pteridophytes of Java and assessing their conservation status are need to be done. The objectives of this study are: (1) to provide the preliminary list of the rare species of Pteridophytes in Mt. Slamet, (2) determine the distribution and habitat of each species. The species was categorized as rare species if it was encountered in less then 10 sites and or the population was less then 20 plants. Random search with belt transect (20 m x 500 m with a sub set 20 m x 100 m) was set up to record the occurence ofspecies in one or more hektar. Twelve species included in 10 genera are recorded as the rare species in Mt. Slamet namely: (1) Asplenium paradoxum Blume, (2) Christensenia aesculifolia (Blume) Maxon, (2) Cyathea glabra (Blume) Copel., (4) Cyathea oinops Hask., (5) Huperzia phlegmaria (L.) Rothm., (6) Pityrogramma austroamericana Domin, (7) Psilotum complanatum Sw., (8) Pteris insignis Mett. Ex Kuhn, (9) Pteris wallichiana J. Agardh., (10) Pyrrosia asterosora (Baker) Hovenkamp, (11) Tectaria zollingeri (Kurz) Holttum, dan (12) Thylacopteris papillosa (Blume) J.Sm. Three species are reported as new records for Java, viz. Pteris insignis, P. wallichiana, and Pyrrosia asterosora. Every species has its own distribution range and habitat characteristics

The pattern leaf venation of Apocynaceae is brochidodromous, intercosta pa-tterns are reticulate and parallel with anastomose ending and blind. There is no report of venation pattern of sepal and petal. Perianthium is derivated from leaf as the result of tropofil differentiation, while pistil and stamen are derivated from sporofil. This research aims to interpret the character of sepal and petalas modification of leaf refer to leaf venation pattern in Apocynaceae. Leaf clearing method was used in this research. The result showed that within 8 genera of Apocynaceae, the venation pattern of sepal and petal is more simple than leaf in primary vein, branch of primary vein, secondary vein, areolar, and vein endings. Sepal and petal have not secondary vein and doesn’t made intercosta and areolar region. Leaf has intercosta and areolar region. Pattern of vein ending in sepal and petal is blind ending, and leaf vein ending pattern anastomose, blind ending, and branched two or three times. Sepal and petal are modification of leaf that has more primary vein.It does not form vein, intercosta region, and blind ending.

Among the diversity of fruits in West Kalimantan is mangosteen (Garcinia mangostana L.) in ovoid shaped and not round as in general. From the field observation, the ovoid mangosteen is distributed in several locations, namely in District Landak, Singkawang, Sambas, Bengkayang and Sanggau. Profile of the mangosteen tree which will be released as ovoid mangosteen is from Sempalai Sebedang Village, District of Sambas

The objective of this study is to determine the genetic variability of porang atdifferent populations based on analysis of trnL intron sequences. Research was conducted in East Jawa, which is porang population at Jember (Mayang: MY), Malang (Lawang: LW, Kalipare: KP), Blitar (Brongkos: BL), Nganjuk (KPH tritik: TR), Madiun (Klangon: KL, KPH Saradan: MD), Bojonegoro (Klino: KN). Exploration conducted in 8 populations to take samples of young leaves as many as three sheets at two different individuals of each population. Then extract the DNA, and amplify the trnL intron using universal primers 'c' and 'd', then were purified and sequenced. The results of sequencing were analyzed the genetic variation and relationship based on Maximum Parsimony tree by MEGA5 software. Sequencing of 16 individuals porang, produce 13 individuals which have a clear chart chromatography which is resulting in the proper sequence and can be used in subsequent analyzes. The sequences showed the differences in nucleotide base composition of each individual. Six region is also known as conserved region, 52 sequences nucleotide variability, and 8 deletion. The phylogeny tree showed four clade Major. Porang were clustered randomly, not based on the population to which the individual is taken. Thus, the origin of porang at each study site cannot be identified based on the geographical analysis.
