Preliminary study on morphological characteristics of araceae species using phenetic approach / Liliwirianis Nawi ... [et al.]

Araceae is a large family consisting Aroids or Arums. It is a monocot plants characterised by
the inflorescence consisting of spadix subtending a spathe. The aim of the study was to
determine the relationship of 13 species from seven genera of Araceae using phenetic
approach. The seven genera are Anthurium, Spathyphyllum, Monstera, Philodendron,
Syngonium, Alocasia and Caladium. A cluster analysis was performed using the Multivariate
Statistical Procedures Version 2.2 (MVSP) on 22 morphological characters of selected
species. Based on the similarity of morphological characters, these 13 species are clustered
into three groups: (1) Anthurium forgetii and A. leuconeurum, (2) M. oblique expilata, P.
scandens oxycardium and Monstera sp. 1 and, (3) M. deliciosa, P. scandens and
Philodendron sp. 1. The cluster analysis indicates Caladium sp. 1 had the lowest similarities
(5.6%) compared to other 12 species. Meanwhile, M. deliciosa and P. scandens exhibit the
highest similarity (68.4%) for both analyses.
