“…They are particularly common in herbaceous vines and among asterids (Supplementary Figure 1B ). This condition is found in Hernandiaceae (Laurales), in the magnoliids; Menispermaceae, Ranunculaceae, and Papaveraceae (all Ranunculales), early eudicots; Tropaeolaceae (Brassicales; Figure 3F ; Bulacio, 2013 ), in the rosids; and, Solanaceae (Solanales), Bignoniaceae (Lamiales), and Asteraceae (Asterales), in the superasterids. In various species in which this tendril type is found, petioles begin to function exclusively as a tendril after clasping the support, with the leaf blade undergoing abscission, as is observed in Perianthomega vellozoi (Bignoniaceae).…”

Convergent Evolution and the Diverse Ontogenetic Origins of Tendrils in Angiosperms

Climbers are abundant in tropical forests, where they constitute a major functional plant type. The acquisition of the climbing habit in angiosperms constitutes a key innovation. Successful speciation in climbers is correlated with the development of specialized climbing strategies such as tendrils, i.e., filiform organs with the ability to twine around other structures through helical growth. Tendrils are derived from a variety of morphological structures, e.g., stems, leaves, and inflorescences, and are found in various plant families. In fact, tendrils are distributed throughout the angiosperm phylogeny, from magnoliids to asterids II, making these structures a great model to study convergent evolution. In this study, we performed a thorough survey of tendrils within angiosperms, focusing on their origin and development. We identified 17 tendril types and analyzed their distribution through the angiosperm phylogeny. Some interesting patterns emerged. For instance, tendrils derived from reproductive structures are exclusively found in the Core Eudicots, except from one monocot species. Fabales and Asterales are the orders with the highest numbers of tendrilling strategies. Tendrils derived from modified leaflets are particularly common among asterids, occurring in Polemoniaceae, Bignoniaceae, and Asteraceae. Although angiosperms have a large number of tendrilled representatives, little is known about their origin and development. This work points out research gaps that should help guide future research on the biology of tendrilled species. Additional research on climbers is particularly important given their increasing abundance resulting from environmental disturbance in the tropics.

“…species of Clematis (Ranunculaceae) and Cysticapnos (Papaveraceae). Although tendrils derived from twining petioles have evolved numerous times within angiosperms, they are typical of some taxa, such as Tropaeolum (Brassicales; Figure 3F ; Bulacio, 2013 ).…”

The family Tropaeolaceae was reported for the first time in Saudi Arabia. The new record (Tropaeolum majus L.) from the Tropaeolaceae family was found in damp and exposed semi-shaded habitats between roughly 1800 and 2132 m elevation in southwestern Saudi Arabia. Illustrations, photos, taxonomic description, distribution map, key and information about the habitat of the plant were given. This study suggests that the new record is an introduced alien plant into Saudi Arabia. Bangladesh J. Plant Taxon. 29(1): 79-84, 2022 (June)
