Doctoral thesis
Taxonomy and systematics of Urophyllum (Rubiaceae) in Thailand and Indochina.
The genus Urophyllum Wall. is a taxonomically problematic genus of Rubiaceae in Thailand due to the lack of a recent taxonomic revision and identification key to the species. This has led to confusion in the identification of species and no conservation status assessments for the genus. The aim of this...Yooprasert, Sawita

Reassessment of morphological species delimitations in the Cyperus margaritaceus-niveus complex using morphometrics.
– The complex is a group of ten tropical species from sub-Saharan Africa and Madagascar: , , , , , , , , , and . They are characterised by a capitate head of white-yellow spikelets and modified culm bases and recent molecular analysis puts them in a distinct clade....Xanthos, Martin ; Mayo, Simon J. ; Larridon, Isabel

Morphological Continua Make Poor Species: Genus-Wide Morphometric Survey of the European Bee Orchids (Ophrys L.).
Despite (or perhaps because of) intensive multidisciplinary research, opinions on the optimal number of species recognised within the Eurasian orchid genus Ophrys range from nine to at least 400. The lower figure of nine macrospecies is based primarily on seeking small but reliable discontinuities in DNA ‘barcode’ regions, an approach... -

Measuring relative flower size in Anthurium (Araceae) as a continuous quantitative character.
Relative flower size (RFS) was studied quantitatively in natural populations of Anthurium erskinei (one population) and A. talmonii (two populations) to investigate its potential as a taxonomic descriptor. RFS is defined as the ratio of spadix diameter and transverse floral width in the same region of the spadix. Variation was... -

Challenges of applying monophyly in the phylogenetic shallows: taxonomic reappraisal of the Dactylorhiza maculata group.
The first study of the taxonomically critical European orchid genus to use next-generation DNA sequencing generated the statistically best-supported reconstruction of its phylogeny to date. However, the two competing topologies obtained within the monophyletic Section differed radically in the placement of the s.s.– clade. Both topologies showed to be nested...
