Revisiting an ecophysiological oddity: Hydathode‐mediated foliar water uptake in Crassula species from southern Africa.
Hydathodes are usually associated with water exudation in plants. However, foliar water uptake (FWU) through the hydathodes has long been suspected in the leaf‐succulent genus (Crassulaceae), a highly diverse group in southern Africa, and, to our knowledge, no empirical observations exist in the literature that unequivocally link FWU to hydathodes... -

Cell wall polysaccharide and glycoprotein content tracks growth‐form diversity and an aridity gradient in the leaf‐succulent genus.
Cell wall traits are believed to be a key component of the succulent syndrome, an adaptive syndrome to drought, yet the variability of such traits remains largely unknown. In this study, we surveyed the leaf polysaccharide and glycoprotein composition in a wide sampling of species that occur naturally along an... -

Are cell wall traits a component of the succulent syndrome?
Succulence is an adaptation to low water availability characterised by the presence of water-storage tissues that alleviate water stress under low water availability. The succulent syndrome has evolved convergently in over 80 plant families and is associated with anatomical, physiological and biochemical traits. Despite the alleged importance of cell wall...Fradera-Soler, Marc ; Leverett, Alistair ; Mravec, Jozef ; Jørgensen, Bodil ; Borland, Anne M. …

Madagascar’s extraordinary biodiversity: Threats and opportunities.
Madagascar’s unique biota is heavily affected by human activity and is under intense threat. Here, we review the current state of knowledge on the conservation status of Madagascar’s terrestrial and freshwater biodiversity by presenting data and analyses on documented and predicted species-level conservation statuses, the most prevalent and relevant threats,... -

Madagascar’s extraordinary biodiversity: Evolution, distribution, and use.
Madagascar’s biota is hyperdiverse and includes exceptional levels of endemicity. We review the current state of knowledge on Madagascar’s past and current terrestrial and freshwater biodiversity by compiling and presenting comprehensive data on species diversity, endemism, and rates of species description and human uses, in addition to presenting an updated... -

Euphorbia mbuinzauensis, a new succulent species in Kenya from the Synadenium group in Euphorbia sect. Monadenium (Euphorbiaceae).
, a succulent new species of the group in Euphorbiaceae from Makueni County, Kenya, is described and illustrated. Morphologically, it is most similar to , but differs mainly by its shrubby habit (up to 4 m), abaxial leaves surfaces with densely stellate hairs, 2–4-forked cymes, smaller bracts (ca. 2.5 ×...Wei, Neng ; Mutie, Fredrick Munyao ; Mwachala, Geoffrey ; Grace, Olwen M. ; Hu, Guang-Wan …

Elastic and collapsible: current understanding of cell walls in succulent plants.
Succulent plants represent a large functional group of drought-resistant plants which store water in specialized tissues. Several co-adaptive traits accompany water-storage capacity to constitute the succulent syndrome. A widely reported anatomical adaptation of cell walls in succulent tissues allows them to fold in a regular fashion during extended drought, thus...
