Abstract

Baturraden Botanical Garden is a complex ecosystem. Its natural resources, including several species of fern, provide an opportunity to be managed sustainably so it can be used to fulfill a long term of public need. This research was aimed to know the diversity of fern species and its potential as ornamental plants. The research was using survey method. The data was analyzed using descriptive comparative analysis. Species identification was performed by comparing the samples with herbarium specimens and also using identification keys. During the observation, 26 species of fern were found, which is consisted of 14 terrestrial species and 12 epiphyte species. Nephrolepis bisserata (Sw.) Schott. was terrestrial species with highest individual number and widest dispersion, whereas terrestrial species with smallest individual number and the narrowest distribution was Blechnum orientale Linn. Epiphytic fern species with highest individual number and widest dispersion was Nephrolepis falcata (Cap.) C. Chr., whereas epiphytic species with smallest individual number and narrowest distribution was Davallia triphylla Hk. From 26 fern species which were found at Baturraden Botanical Garden, 22 fern species were potential as ornamental plant which can be grew up either on land, pot or on host plant.

Abstract

Salak or snake fruit (Salacca zalacca) or salak is a kind of popular fruit originated from Sumatra and Java. There are many cultivars including both the wild and the hybrid ones. One of many cultivars namely S. zalacca ‘Kelapa’ was observed for their distribution.  This cultivar is considered to be unusual because it has only a few spines on its petioles. This cultivar was previously found only in Karangasem Bali especially in the subdistrict of Sibetan, Selat, and Rendang and in Batujajar in West Java.  A new record was found in Banjarnegara especially in Sokanandi Village. A map of the distribution of this cultivar is presented.
