“…Compared to the stems of Vitis sp., the stem vasculature of Tetrastigma also has an open concentric arrangement(Pace et al 2018). This stem anatomy is also consistent across genera in the Vitaceae such as Cayratia and Pterisanthes(Najmaddin et al 2011)…”

Tetrastigma (Vitaceae) are a genus of tropical lianas that are hosts for parasitic plants in the family Rafflesiaceae. Since the stem of Tetrastigma is creeping and often devoid of leaves, it is often mistakenly visually identified as a root. Rafflesia flowers at the ground level (i.e. terrestrial flowers) have been documented to grow on Tetrastigma roots, but it is unclear whether those that arise aerially emerge from host root or stem organs. In this study, we present a new, lessdestructive means of sampling Tetrastigma leucostaphylum, which is a host of many Rafflesia species. Histological observation of two 250 cm above-ground aerial samples confirmed that both were stems, as shown by distinct anatomical features (compactly arranged vascular bundles with simple phloem bundles) in contrast to roots, which had loosely arranged vascular bundles with ramified phloem bundles. Clearer identification of Tetrastigma vine infected with aerial Rafflesia is needed to confirm whether the parasitic flower grows on a stem or on an erect aerial root to better understand the biology of this enigmatic Rafflesia species that have evaded cultivation and ex situ conservation efforts. This new sampling method may be a useful way to identify the Tetrastigma vine in the future due to its less invasive nature compared to severing the whole vine.

“…Researchers only found this species in one location. Taxonomically these plants belong to the Vitaceae family, with special features having tendrils and fruit that resemble grapes (Chnar et al, 2011). Cayratia is a tropical and subtropical genus distributed in Asia, Africa, Australia and the Pacific Islands, consisting of 63 species (Wen, 2007).…”

Mount of Nglanggeran is areas that have diversity of unique flora. This area is uninhabited, so many diversity flora that not identified and have not experienced exploration. Therefore, further exploration of plant diversity is needed. The research is aim to inventory, documentation, and find out the diversity of understory (shrubs and herbs) on Mount Nglanggeran. This research used survey and exploration methods. The researchers documented shrubs and herbs species. Based on result, found 44 family consist of 144 species shrubs and herbs. Those species are flora that has specifically characteristics.

“…I noticed that the tendrils of C. japonica did not coil around the leaves of Oxalis debilis. Oxalis, as well as Cayratia species, contain high concentrations of oxalate compounds in their leaves [22,23]. Thus, I hypothesized that oxalate compounds are the cues of conspecific leaves that inhibited the coiling response of C. japonica tendrils.…”

Vine tendrils use contact chemoreception to avoid conspecific leaves

Movement and growth habit of climbing plants have attracted attention since the time of Charles Darwin; however, there are no reports on whether plants can choose suitable hosts or avoid unsuitable ones based on chemoreception. Here, I show that the tendrils of Cayratia japonica (Vitaceae) appear to avoid conspecific leaves using contact chemoreception for oxalates, which are highly concentrated in C. japonica leaves. The coiling experiments show that C. japonica has a flexible plastic response to avoid coiling around conspecific leaves. The coiling response is negatively correlated with the oxalate content in the contacted leaves. Experiments using laboratory chemicals indicate that the tendrils avoid oxalate-coated plastic sticks. These results indicate that the tendrils of C. japonica avoid coiling around a conspecific leaf based on contact chemoreception for oxalate compounds. The tendrils of climbing plants may function as a chemoreceptor system to detect the chemical cues of a contacted plant.
