Detailed descriptions of the wood and bark anatomy of five representative Centella species are presented. The wood structure is reported for the first time for this genus. Scalariform perforation plates occur frequently in the secondary xylem of two Centella species (Centella difformis and C. rupestris) indicating a phylogenetic relationship with Apiopetalum and Mackinlaya, the only other genera of Apiaceae where this feature occurs regularly and not merely as an aberration. This character…

The systematic significance of bark structure in southern African genera of tribe Heteromorpheae (Apiaceae)

The bark anatomy of five southern African genera of tribe Heteromorpheae (Apiaceae) has been investigated and the shape of the epidermal cells, the presence of trichomes and the occurrence of secretory canals in the secondary phloem rays can be used as diagnostic characters for species identification.

A phylogenetic and functional perspective on the origin and evolutionary shifts of growth ring anatomical markers in seed plants

By embodying a functionally and evolutionarily significant concept in growth rings, this work reveals a new panorama for their frequency and shows how common they are in diverse lineages of tropical plants.



Systematic implications of wood and bark anatomy in the Pacific Island genus Meryta (Araliaceae)

Wood anatomy was examined in 16 species of Meryta (a genus of c. 35 species) and bark anatomy was studied in 12 species. All but two of these taxa form an assemblage corresponding to the Northern Arc

Systematic and phylogenetic value of wood anatomy in Heteromorpheae (Apiaceae, Apioideae)

Variation in the wood anatomy of 31 samples from nine species of Anginon is not correlated with habitat, but instead appears to reflect adaptations to seasonal aridity found in both ecosystems.

Comparative bark anatomy of Bursaria, Hymenosporum and Pittosporum (Pittosporaceae)

Bark anatomy in 3 species of Bursaria, 9 species of Pittosporum, and in the single species of monotypic genus Hymenosporal was examined confirmed a relationship between Pittsporaceae and other Apiales rather than its traditional placement into Rosales as suggested by traditional taxonomy and gross morphology and molecular phylogenetics.

Higher level relationships of Apiales (Apiaceae and Araliaceae) based on phylogenetic analysis of rbcL sequences

Clarification of phylogenetic relationships has concomitantly provided insights into trends of morphological evolution, and suggests that the ancestral apialean taxon was probably bicarpellate, simple-leaved, woody, and paleotropical.

The potentials and limitations of dicotyledonous wood anatomy for climatic reconstructions

At present the fossil wood record for most epochs and regions is too limited to permit detailed reconstructions of their past climate, andibilities for reliably using dicotyledonous wood for climatic reconstructions appear restricted to the Tertiary and Quaternary.

Relationships of the genus Azorella (Apiaceae) and other hydrocotyloids inferred from sequence variation in three plastid markers

The results confirm previous observations that the hydrocotyloids are an unnatural assemblage of taxa from at least four different groups, of which one belongs to Araliaceae and the remaining ones to Apiaceae.

Evolution in Apiales: nuclear and chloroplast markers together in (almost) perfect harmony

Results from this study confirm that Apiales comprise five major lineages: core Apiaceae, core Araliaceae, Pittosporaceae, the Mackinlaya group and the Myodocarpus group, and the nature and extent of the polyphyly is confirmed.

Relationships among "ancient araliads" and their significance for the systematics of Apiales.

To reevaluate the phylogenetic position of the "intermediate" araliad genera, molecular data were collected from nuclear (rDNA ITS) and plastid sequences from a complete or near-complete sampling of species in each genus, and relationships among the species within these clades are largely supported by morphological and anatomical data.


Three stages of secretory canal development (canal formation, active secretion, and senescence) were distinguished on the basis of TEM observations and secretory processes were not indicated in the highly vacuolated senescent epithelial cells.
