Abstract

Miconia crenata is a widely spread species that occurs in multiple ecosystems. However, there is limited information on M. crenata invasion biology, ecology, and anatomy, particularly in the context of mountainous tropical forest and biodiversity management. Therefore, we examined elevation effects upon leaf anatomical structure of exotic invasive M. crenata at Mount Gede-Pangrango National Park (MGPNP). We sampled the leaves at four different elevations i.e., 715 m asl, 800 m asl, 900 m asl, and 1,000 m asl. Cross section leaf anatomy specimens of M. crenata were obtained by using paraffin method and stained with safranin and fast green. This study found that M. crenata leaf anatomy was correlated with elevation shown by changes in leaf tissue thickness and stomata size. Further study is needed of leaf anatomical variation of exotic invasive species along driven by soil properties and the variation across different plant taxa and growth forms. Such studies are important to determine adaptation capacity of invasiveness.

Abstract

Study in leaves anatomy of twenty nine samples of the species classified under Pandanus, Freycinetia and Sararanga of Pandanaceae had been undertaken to unravel generic relationship among of these taxa with a view to provide a set of diagnostic characters for taxonomic identification. The fourth genus of Pandanaceae, Benstonea is not included in this analysis since there are no representative samples. Four anatomical diagnostic characters had been identified at the generic level such as present and absent of papillae, stomatal arrangement types, present and absent of bundle sheath extension and hypodermal thickness and its shape. Pandanus has papillae, amphistomatous stomata, bundle sheath extension present and hypodermis thin and rectangular; Freycinetia lacked of papillae, stomata hypostomatous or amphistomatous, bundle sheath extension absent and hypodermis thick and hexagonal or rounded; meanwhile Sararanga has no papillae, stomata amphistomatous, bundle sheath extension absent and hypodermis thin and flatten. An identification key to those genera based on anatomical diagnostic characters is provided.

Abstract

Cross sections of leaves of Pandanus spp. showed that their leaf anatomy is similar, whilst paradermal sections indicated that crystal numbers differ. Variation was found in the anticlinal epidermal cell walls, stomata, hypodermis, sclerenchyma, mesophyll and crystals, as discussed in this paper.
