Phytomelanin is a mechanically hard, blackish, and inert substance rarely found in plants. In Asteraceae, this was historically associated with the Heliantheae alliance, but recent studies have observed it unrelated groups as Heterocoma Wunderlichia. During taxonomic investigation, we phytomelanin cypselae of Lychnophora salicifolia an unusual feature Vernonieae previously only Heterocoma. Furt...

From the aerial parts of Ajuga salicifolia (L.) Schreber, a new ionone glycoside (3beta-hydroxy-7,8-dihydro-4-oxo-beta-ionol-9-O-beta-D-glucopyranoside) was isolated, along with the known compounds, corchoionoside C, 8-O-acetylmioporoside, ajugol, harpagide, 8-O-acetylharpagide, lavandulifolioside and leonosides A and B. This is the first report of the occurrence of ionone glycosides and 8-O-ac...

A brief synopsis of the genus Allamanda (Apocynaceae, Rauvolfioideae) in Colombia is presented, including a key, photographs of the species, and a new combination, A. salicifolia.

The flowers of Hyaloseris salicifolia afforded known ivasperin, while the leaves afforded ivasperin and 2-O-(6'-O-acetyl-beta-D-glucopyranosyl)-ivasperin, whose structure was determined by spectroscopic methods.

Ficus is a exible replication facility with optimistic concurrency control designed to span a wide range of scales and network environments. Support for partitioned operation is fundamental to the Ficus design but was not widely exercised in early Ficus use. This position paper reports recent experiences using Ficus in settings where some replicas are only occasionally connected to a network, a...

The interaction between figs (Ficus, Moraceae) and fig-pollinating wasps (Chalcidoidea, Agaonidae) is one of the most specific mutualisms, and thus is a model system for studying coevolution and cospeciation. In this study we focused on figs and their associated fig-wasps found in the Ryukyu and Bonin (Ogasawara) Islands, Japan, because it has been suggested that breakdown in the specificity ma...
