Cornejo Valverde, F.H., J.P. Janovec, and M.W. Tobler. 2006. Floristic diversity and composition of terra firme and seasonally inundated palm swamp forests in the Palma Real Watershed in lower Madre de Dios, Peru. Sida 22:615–633.
A tree species inventory of 7 hectares of lowland subtropical moist forest in the Palma Real River watershed of lower Madre de Dios, including a previously unstudied type of palm swamp. Satellite imagery illustrates the extent of the palm swamp forests throughout the region. Wetland forest vegetation was compared with the surrounding terra firme forests, based on plots with a total of 3534 trees _10 cm DBH, belonging to 442 species in 62 families. Three distinct forest types resulted from Principal Components Analysis (PCA) and WPGMA cluster analysis of family and species abundance data, including two types of terra firme forests and a palm swamp forest. Fabaceae and Arecaceae were the most important plant families across all plots; Arecaceae (palm family) significantly distinguishes the palm swamp forest plots.

A formal account of the genera of tribe Astereae of the sunflower family -- included are 210 genera. Each genus is described and a key to genera is provided.
Nesom, G.L. 2006. Taxonomic overview of the Heterotheca villosa complex (Asteraceae: Astereae). Sida 22:367–380.
Heterotheca villosa has recently been treated as a complex species with nine varieties (sensu Semple), most of which are sympatric in various degrees. The current study approaches the taxonomy of this group from a different perspective, regarding sympatry as an indicator either of reproductive isolation or of arbitrary identifications based on typological concepts. The taxa of the H. villosa complex are here treated as 5 species, H. villosa itself with 2 or 3 varieties. Maps show the generalized distributions of the taxa of the complex sensu Semple, and a nomenclatural summary outlines an alternative taxonomy.

Nesom, G.L. 2006. Taxonomic review of Symphyotrichum patens (Asteraceae: Astereae). Sida 22:1075-1080.
The current study recognizes and maps only 2 varieties within Symphyotrichum patens (vs. 3 varieties, as previously, and in the FNA treatment). Within var. patens, tetraploids apparently have twice arisen independently from persistent diploid ancestors.

Distribution records for various species, as presented in corresponding FNA treatments, are documented and discussed.
Sanders, R.L. 2006. Taxonomy of Lantana sect Lantana (Verbenaceae): I. Correct application of Lantana camara and associated names. Sida 22:381–421.
Current usage of the name Lantana camara includes a widely cultivated and naturalized hybrid species that is taxonomically distinct from native L. camara. Plants identified by this name are well known, not only as hardy ornamentals worldwide but also as naturalized weeds with devastating economic impact in humid tropical areas of the Old World. Considerable effort has been made toward their biological control, but the taxonomy of these cultivated and naturalized plants is not well understood. To determine the correct name of the cultigen, all names in Lantana sect. Lantana are reviewed, typified, and taxonomically disposed. No available name applies to the cultigen, which is newly described as Lantana X strigocamara R.W. Sanders. Origin of the named hybrids in the L. camara complex is hypothesized.
