Phenetic analysis of Passiflora in Probolinggo-East Java based on generative characteristic

Passiflora has beneficial value as a medicine plant. However, with its many morphological variations, it is difficult to identify and classify them. Therefore, observation of its morphological characteristic and the phenetic relationships between Passiflora species is essential. This study aims to determine the morphological variations of the genus of Passiflora in Probolinggo and their phenetic relationship based on morphological characteristics of generative organs. This explorative-descriptive study was conducted using the cruise methods in the Probolinggo area on 0-500 m asl. Identification of the morphological feature was conducted to the species level using the Backer dan Bakhuizen van der Brink identification key in their book entitled Flora of Java. Morphological characters of generative organs were selected, then the similarity index was calculated using the association coefficients. The results were analyzed using cluster analysis, then illustrated in the form of the dendrogram. This study shows that in the Probolinggo area, seven species of Passiflora are found, including Passiflora ligularis, Passiflora foetida L., Passiflora quadrangularis L., Passiflora edulis Sims, Passiflora caerulea-racemosa Sabine., Passiflora coccinea L., and Passiflora vitifolia H.B.K.
