The Euterpeinae contains six neotropical genera. There has been continual disagreement on generic and subgeneric boundaries in the subtribe.Euterpe andPrestoea, andJessenia andOenocarpus, have been repeatedly united and separated. A phylogenetic analysis based on 54 morphological and anatomical characters gave one tree of 127 steps.Euterpe is separate fromPrestoea, butJessenia andOenocarpus are best...
Bactris neomilitaris, a new species from Central America, is described and illustrated. It is compared toBactris militaris, in which it was formerly included.
Cardiac Syndrome X (microvascular angina) and the more recently described metabolic Syndrome X (an epidemiological association between insulin resistance and atheroma, dyslipidaemia, and hypertension) may have more in common than the chance of their common sobriquet, in view of evidence that microvascular angina too is characterised by insulin resistance and endothelial dysfunction. The implications...
Five species ofOenocarpus from the Río Caquetá, in the Colombian Amazon, are discussed. Two of themOenocarpus simplex andOenocarpus makeru are described as new.Oenocarpus bacaba var.parvus is shown to be a synonym ofO. balickii; this species andO. minor are recorded for the first time in Colombia. Some comments on the poorly knownO. circumtextus are also given. The new findings support the inclusion...
The taxonomic history of the poorly known Haitian endemic palmAttalea crassispatha is given. Morphology and pollen morphology are described and illustrated. A discussion is given concerning its position within the Attaleinae. In particular, staminate flower morphology of the subtribe is discussed.
The history of the genus Parajubaea is summarized. A description of the genus is given, followed by a key to, and descriptions of both species. The origin of the cultivated P. cocoides is discussed.
Asterogyne guianensis, a new species from French Guiana, is described and illustrated. The differences between this and the morphologically similarA. spicata are given. A map and discussion of distribution is given for all five species of the genus.
Ynesa colenda O. F. Cook has remained a poorly known palm since its description in 1942. Recent collections by the authors in Ecuador make it clear that the palm correctly belongs toAttalea, and the transfer is here made. A complete description of the palm is given, as well as notes on its relationships, distribution, pollination, and economic importance.
Prestoea darienensis Henderson is described and illustrated. A discussion is given of morphological groupings within the genus, and the place of the new species.
Socratea montana, a new species from Colombia, is described and illustrated, and its relationships discussed. Two groups of species within the genus are characterized.
