ERICACEAE OF LATIMOJONG RANGE, SOUTH SULAWESI Abdulrokhman Kartonegoro
Floribunda Vol. 4 No. 8 (2014)
Publisher : PTTI

The family of Ericaceae in Sulawesi is represented by four genera namely Diplycosia Blume, Gaultheria L., Rhododendron L. and Vaccinium L. The inventory number of species family Ericaceae in Latimojong Range was conducted based on field collections and herbarium study in Herbarium Bogoriense. Thirty species and two varieties are recognized consist of 4 of Diplycosia, 3 of Gaultheria, 19 of Rhododendron and 6 of Vaccinium. Twenty seven species and two variety are endemic to Sulawesi while 17 of it endemic for Latimojong Range. High endemicity of species Ericaceae in Latimojong Range will need more concern and protection as a conservation site.

THE STELAR ANATOMY OF STIPE AND ITS TAXONOMIC SIGNIFICANT IN DIPLAZIUM (ATHYRIACEAE) Titien Ngatinem Praptosuwiryo; Dedy Darnaedi
Floribunda Vol. 4 No. 8 (2014)
Publisher : PTTI

Anatomical study on transection of stipe near lamina were carried out on 27 species of Diplazium from Western part Malesia (Java, Sumatra, Kalimantan). The aim of this study is to examine stelar anatomical characters for supporting species delimitation in Diplazium. The leaf-trace shape of Diplazium stipe is varying among species and constant among the adult individuals in a species. Leaf-trace shapes of Diplazium can be classified into five main types: (1) uninterrupted V-shaped, (2) interrupted V-shaped, (3) uninterrupted U-shaped, (4) interrupted Ushaped, and (5) W-shaped. Each type diversifies into some different derivative forms that enable to determine a species among closely related species. Therefore the leaf-trace shapes are important diagnostic character which support species delimitation in Diplazium.

PHYLOGENETIC RELATIONSHIPS OF INDONESIAN BANANA CULTIVARS INFFERED FROM TRNL-F INTERGENIC SPACER OF CHLOROPLAST DNA Amin Retnoningsih; Rita Megia; Alex Hartana
Floribunda Vol. 4 No. 8 (2014)
Publisher : PTTI

A phylogenetic relationship of Indonesian banana cultivars was conducted using trnL-F intergenic spacer of chloroplast DNA sequences. The ingroup was 39 banana accessions from various genomic groups in Indonesia consisting of 9 AA/AAA; 11 AAA; 2 BB; 13 AAB; and 4 ABB cultivars and 12 sequences of different taxa of Musa downloaded from GenBank consisting of 4 AA wild; 1 AA; 3 AAB; and 4 ABB cultivars. Two accessions from section Rhodoclamys and Australimusa were used as the outgroup. The 39 accessions of the ingroup and the 2 accessions of the outgroup were analyzed using primers of the trnL-F intergenic spacer. The results showed that sequence of the trnL-F region can clearly distinguish 40 banana accessions having the A-type chloroplast (AA wild; AA; AA/AAA; AAA; AAB; and ABB) from those 11 accessions having the B-type chloroplast (BB, AAB, and ABB). The A-type chloroplast accessions are most probably derived from female Musa acuminata, while the B-type chloroplast accessions may be derived from female M. balbisiana. However, the specific M. acuminata ancestor of each cultivar remains unidentified.

KEANEKARAGAMAN LUMUT EPIFIT PADA GYMNOSPERMAE DI KEBUN RAYA BOGOR Fibo Adhitya; Nunik Sri Ariyanti; Nina Ratna Djuita
Floribunda Vol. 4 No. 8 (2014)
Publisher : PTTI

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.

Lejeuneaceae anak suku Ptychanthoideae di Hutan Sibayak Sumatra Utara Etti Sartina Siregar; Nunik Sri Ariyanti; Sri S. Tjitrosoedirdjo
Floribunda Vol. 4 No. 8 (2014)
Publisher : PTTI

Sixteen species of Ptychanthoideae are found in Sibayak Forest North Sumatra, of which thirteen are previously known, while three are new records (Mastigolejeunea virens, Schiffneriolejeunea tumida and Thysananthus retusus) for Sumatra. An identification key to the species and description of Ptychanthoideae from Sibayak Forest, North Sumatra are provided.
