The Relationship of Piperaceae Based On Morphological Character of Vegetative Organ in Meru Betiri National Park Jember East Java

Abstract

The family of Piperaceae in Meru Betiri National Park Jember East Java is represented by ten species: Peperomia pellucida, P. Sarmentosum, P. aduncum, P. auriculatum, P. retrofractum, P. nigrum, P. canicum, Piper Sp 1, P. betle and Piper Sp 2. Taxonomic studies were performed to determined the relationship between each species based on morphological characters. By using hierarchical cluster analysis, the relationships between species were illustrated in a dendrogam. The results show that from 10 species collected can be grouped into 7 clusters as follow: (P. aduncum + (Peperomia pellucida) + (P. retrofracum) + (P. canicum) + (P.betle) + (P. sarmentosum) + (P. auriculatum + Piper Sp. 2 + P. nigrum + Piper Sp.1) ). The closest relationship was obtained between species of SP 4 (P. auriculatum) and SP 10 (Piper Sp. 2) with 0.7% similarity level and 24.307 of the coefficient value. The farthest relationship was obtained between SP 1 (Peperomia pellucida) and SP 3 (P.Aduncum) with 25% similarity level and a coefficient value of 387.415.
