Mada. The results indicated that Vanda tricolor flowers were visited by insects from three orders, six families, and eleven species in the morning; four orders, six families, and nine species in the daytime; and two orders, three families, and five species in the afternoon with various role. In this research, we also observed pollination activity potential by Xylocopa latipes (Hymenoptera: Apidae). There were 14 V. tricolor flower-visiting insects from four orders and nine families. There were no significant differences between the insect diversity of the morning and daytime, while in the afternoon there was a decline in the diversity of the insects.
In addition to the studies on potential medicinal uses of Trichosanthes, a screening on phytochemical compounds and antioxidants activity of Trichosanthes tricuspidata from Bangli, Baturiti, Bali, Indonesia, was conducted on its leaves, fruits, peels, and seeds. Qualitative phytochemical tests were conducted to find out the chemical constituents of T. tricuspidata, while its antioxidant activity was tested by applying DPPH (1,1-diphenyl-2-picrylhydrazyl radical) method. As a result, flavonoid, alkaloid, terpenoid, tannin, and saponin were present in all methanolic extracts of T. tricuspidata. Furthermore, the best antioxidant activity was exhibited by peel extract. After all, T. tricuspidata contains a prospective compound agent for medicinal use.
Nervilia
is an orchid genus of approximately 80 ephemeral taxa that are widely distributed throughout the subtropical and tropical regions of Africa, Asia, Australia, and Oceania. Scientific information and research materials gathered from Bali are scarce. While trekking around Bali, we encountered a few representatives of this taxon. This led to further investigation of the genus and its occurrence in Bali, which is summarized in this article. New records of
N. concolor
and
N. punctata
from Central Bali have enriched previously known sites, and as species that appear ephemeral often go unnoticed this is a valuable contribution to the understanding of the geographic distribution of this genus.
(2): 65-71. -A new species, A ppendicula cordata (sect. Pododesme) from eastern Indonesia, is described and illustrated. Its habit is similar to that of A ppendicula infundibuliformis J. J. Sm., but it differs in having flowers with a cordate appendage and a lip reflexed to the right. An identification key to the species of A ppendicula sect. Pododesme, a distribution map, photos and line drawing are also provided.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
