“…Both studies concluded that there is probably no satisfactory infraspecific classification for these complexes, because populations form a spectrum of morphologically different forms across their distributional range. To date, only two genetic studies have documented the relationships and levels of genetic variation found in palm species complexes (Loo et al ., 1999; Kjaer et al ., 2004), but none has focused on Geonoma .…”

The latest taxonomic account for the palms of the Amazon recognizes two common and widespread varieties of Geonoma macrostachys (Arecaceae) in western Amazonia: acaulis and macrostachys . These varieties are joined by intermediates, which obscure their taxonomic boundaries. An evaluation of the genetic distinctness between G. macrostachys varieties at a local and regional scale is presented. Thirty-one G. macrostachys individuals were randomly sampled from four Peruvian tropical moist forests. Twenty-seven intersimple sequence repeat (ISSR) primers were used, and all clear and reproducible bands were scored and analysed. Of the 99 ISSR bands produced, 51.52% were polymorphic. Nei's gene diversity value ( H ) was 0.2274 and Shannon's information index ( I ) was 0.3237. Clustering, ordination, and analyses of molecular variance (AMOVAs) suggested a lack of genetic distinctness between varieties at the regional level. Individuals clustered by geographical provenance, and two main groups were identified. A significant genetic differentiation between sympatric varieties occurred only in the northern locality ( Φ ST = 0.359, P = 0.000). A hierarchical AMOVA revealed that the genetic diversity in G. macrostachys mainly lies between localities (76.58%). Mantel's test revealed no significant correlation between the geographical and genetic distances between individuals. We do not support the recognition of the two taxonomic varieties studied.

“…Our previous study using RAPD (Random Amplified Polymorphic DNA) profiling on three populations of L. glabra (Loo et al, 1999) revealed genetic diversity among three morphologically differentiated populations located within 40 km of each other in the state of Terengganu in Peninsular Malaysia. Molecular tools such as DNA fingerprinting and sequencing will have to be carried out throughout the distribution range of the species to address gene flow, genetic structuring and relationships of the populations within and among the ranges and to test the congruence of molecular and phenetic data.…”

We studied vegetative and reproductive characters of 74 herbarium specimens of Licuala glabra Griff. (Palmae) collected from 22 localities throughout Peninsular Malaysia. To test the null hypothesis that there are no distinct groups within the species, cluster analysis (nearest neighbour), principal coordinates and principal components analyses were performed on the set of 43 qualitative and quantitative characters. The results obtained suggested that: (1) there are three infraspecific groups within the species, viz., the two published varieties glabra and selangorensis as well as a possible third novel taxon; (2) there is clustering of individuals corresponding t o their geographic localities; (3) clusters generated using only reproductive characters indicate a biogeographic distribution of populations correlated with the mountain ranges in the peninsula.

“…Like that of Borchsenius (1999), this paper is important in palm systematics because of its use of appropriate methodology and conclusive results. Loo et al . (1999) used molecular data to analyse three populations of L. glabra , and used both CA and PCA.…”

A review is given of the role of traditional morphometrics in plant systematics. The three most commonly used techniques of data analysis -Cluster Analysis, Principal Component Analysis and Discriminant Analysis -are discussed. The kinds of data that can be taken from palm specimens and the problems of using specimens as data sources are outlined. Published systematic studies of palms using traditional morphometrics are reviewed. More recent studies indicate that: hybrid zones between species may be common; infraspecific diversity is greater than previously suspected; there may be more than double the currently accepted number of species; and our current knowledge of morphological variation in palms is superficial. A procedure for scientific systematics is given, which incorporates traditional morphometric methods.
