A new subfamily classification of the palm family (Arecaceae): evidence from plastid DNA phylogeny
A new subfamilial classification of the palms is established, in which five subfamilies are recognized, rather than the six that were included in the previous classification, and critical basal nodes are now fully resolved and, in most cases, strongly supported.
Twenty-five years of progress in understanding pollination mechanisms in palms (Arecaceae).
The interaction between the palm and its visiting fauna represents a trade-off between the services provided by the potential pollinators and the antagonistic activities of other insect visitors, suggesting that beetles constitute the most important group of pollinators in palms, followed by bees and flies.
Canopy tree mode of death in a western Ecuadorian rain forest
It was concluded that the predominance of uprooting and snapping in Hoja Blanca mostly resulted from the steep terrain and high precipitation as well as El Nino Southern Oscillation (ENSO) downpours and the different modes created different types of gaps and could thereby influence forest regeneration.

In the first exhaustive sampling of all 65 genera of the Areceae, relationships of two of the tribe's most problematic genera, Heterospathe and Rhopaloblaste are examined using portions of the low-copy nuclear genes phosphoribulokinase (PRK) and RNA-polymerase II subunit B (RPB2).
Floral structure in the neotropical palm genus Chamaedorea (Arecoideae, Arecaceae)
Male and female floral structure has been studied in 28 species of Chamaedorea, the largest palm genus present in the Neotropics, and the taxonomic distribution of selected characters is in some cases congruent with relationships inferred by recently published molecular studies within the group.
Species composition and vegetation structure of an upper montane forest at the summit of Mt. Doi Inthanon, Thailand
Most of the calculated vegetation variables showed significant correlation with altitude: species richness, family richness, diversity, density and crown cover declined with altitude, average tree height was uncorrelated with altitude and basal area increased with altitude.
Inflorescence morphology of some South American Anacardiaceae and the possible phylogenetic trends
- A. Barfod
- 1 February 1988
The tribal divisions in the Anacardiaceae are supported by the inflorescence morphology, and Toxicodendron is exceptional for the tribe Rhoeae having axillary panicles.
Isolation and reduced gene flow among Faroese populations of tea-leaved willow (Salix phylicifolia, Salicaceae)
The genetic structure of the extant populations of Faroese S. phylicifolia was investigated and the patterns suggested imprints of historic introductions and poor gene flow between populations implying risks of drift and inbreeding.
Economic botany of Spondias purpurea (Anacardiaceae) in ecuador
The edible fruits of Spondias purpurea are valued highly throughout the Ecuadorian coastal plain and Andes where they are cultivated. They are also exported to Colombia and Peru. The fruits are…
