In addition to benjaminamide (2), β-amyrin, β-amyrin acetate, lupeol, betulinic acid, β-sitosterol glucoside, a new ceramide glycoside was isolated from the woods of Ficus lutea Vahl (Moraceae). Using mass fragmentation pattern, 1 and 2D NMR spectra and by comparison with published data, the new compound was characterized as 1-O-β-D-glucopyranosyl-(2S,3R,5E,12E)-2N-[(2'R)-hydroxyhexadecanoyl]-o...

A new soft scale (Hemiptera: Coccoidea: Coccidae) species, Pulvinariacaballeroramosae Tanaka & Kondo, sp. n., is described from specimens collected on twigs of Ficussoatensis Dugand (Moraceae) in Bogota, Colombia. The new species resembles Pulvinariadrymiswinteri Kondo & Gullan, described from Chile on Drimyswinteri J.R. Forst. & G. Forst. (Winteraceae), but differs in the distribution of preop...

In the tropical African region the entire drosophilid genus Lissoceplzala and Drosophila $mu species group have evolved a close association with endemic figs (Ficus spp., Moraceae). We previously described the biology of a few of these figdependent drosophilids (Lachaise, 1977). We report here on a further investigation in evergreen rainforests, mainly in western Africa, that has yielded inform...

Furanocoumarins are phytoalexins often cited as an example to illustrate the arms race between plants and herbivorous insects. They distributed in a limited number of phylogenetically distant plant lineages, but synthesized through similar pathway, which raised question unique or multiple emergence higher plants. The furanocoumarin pathway was investigated fig tree (Ficus carica, Moraceae). Tra...

UNLABELLED PREMISE OF THE STUDY The genus Ficus (fig trees) comprises ca. 750 species of trees, vines, and stranglers found in tropical forests throughout the world. Fig trees are keystone species in many tropical forests, and their relationship with host-specific wasp pollinators has received much attention, although many questions remain unresolved regarding the levels of host specificity,...

The list of families with diagonal ("dendritic" or " f1amelike" of other authors) patterns of vessel aggregation is similar to the list of families that have vasicentric tracheids. This paper attempts to deal with apparent exceptions. Because of recent reports of vasicentric tracheids, the families with diagonal vessel aggregations are all also on the list of families with vasicentric tracheids...

This study is the first report to suggest a morphological phylogenetic framework for the seven varieties of Ficus deltoidea Jack (Ficus: Moraceae) from the Malay Peninsula of Malaysia. Several molecular-based classifications on the genus Ficus had been proposed, but neither had discussed the relationship between seven varieties of F. deltoidea to its allies nor within the varieties. The relatio...
