Afrothismiaceae (Dioscoreales), a new fully mycoheterotrophic family endemic to tropical Africa.
is a genus of non-photosynthetic mycoheterotrophs from the forests of continental tropical Africa. Multiple phylogenetic inferences using molecular data recover the genus as sister to a clade comprising mycoheterotrophic Thismiaceae and the photosynthetic family Taccaceae, contrary to earlier placements of and Thismiaceae within Burmanniaceae. Morphological support for separating from the... -

Ethnobotany of Hawaiian figure sculpture
Anecdotal theories about traditional uses of Polynesian woods in relation to social and religious practices were tested using comparative wood identification. The woods used to make 135 figure carvings from the Hawaiian archipelago were identified and compared with 23 figure carvings from elsewhere in Polynesia (especially Tahiti and the Marquesas)....Rudall, Paula J. ; Cartwright, Caroline R.

Evolutionary success in arid habitats: Morpho-anatomy of succulent leaves of Crassula species from southern Africa
Succulence is widely interpreted as an adaptation to drought, usually associated with CAM and xeromorphic features among arid-adapted plants. However, this syndrome can also be observed in species typical of mesic and even hydric environments. The leaf-succulent genus Crassula (Crassulaceae) occurs in contrasting habitats in all nine biomes of southern...Fradera-Soler, Marc ; Rudall, Paula J. ; Prychid, Christina J. ; Grace, Olwen M.

Phylogenetic, Developmental and Functional Aspects of Stomatal Patterning: Lessons from Magnoliids.
The magnoliid clade encompasses 18 extant families arranged in four orders, plus several extinct taxa, including some of the most ancient angiosperm fossils. The clade is characterized by paracytic stomata with a distinct pair of lateral subsidiary cells that flank the guard cells, though other stomatal types are also reported,...Rudall, Paula J.

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... -

From “New Botany” to “New Systematics”: an historical perspective on the Jodrell Laboratory.
Kew’s Jodrell Laboratory was established in 1876 as a centre for botanical research in disciplines including plant physiology, anatomy and embryology, palaeobotany and mycology. Despite relatively little available funding, its location in one of the world’s largest botanic gardens and close to several well-curated plant collections has ensured its continued... -

Evolutionary history of the grass gynoecium.
The grass family (Poaceae) includes cereal crops that provide a key food source for the human population. The food industry uses the starch deposited in the cereal grain, which develops directly from the gynoecium. Morphological interpretation of the grass gynoecium remains controversial. We re-examine earlier hypotheses and studies of morphology...
