Understanding the impacts of these changes on primary producers such as plants, and their value as natural capital, will be crucial for designing measures to reduce the negative consequences of climate perturbations. A multitude of adaptations to heat and water stress have evolved in plants to regulate metabolism and reproduction in water‐limiting environments. The succulent plants also known as succulents or sometimes fat plants having some parts that are more than normally thickened and fleshy, usually to retain water in arid climates or soil conditions. The succulents comes from the latin word sucus, meaning juice or sap succulent plants may store water in various structures, such as leaves and stems.

The problem child of taxonomy by Bruce Bayer y experience with Haworthia dates back to my childhood and spans nearly 70 years of continuous observation. My interest Mwas only able to properly manifest when I began work at the Karoo National Botanical Garden in 1969 and it has since been through many phases. I wrote a formal taxonomic revision of the genus in 1999 and have spent a good bit of the last nine years adding to and verifying what I wrote. Haworthia has always been regarded as a problem child of botany, to be avoided by professional taxonomists for various reasons including an apparent phobia of the many amateur collectors peering over the shoulder while at work. This has puzzled me because it seemed to me genera of the Alooideae (a sub-family) of the Asphodelaceae (the aloe that if the need for good classification and identification was so strong family) are not comfortably classified and the three sets of plants that there was an obligation for botanists to provide the service. So my constitute the genus Haworthia are not only florally distinctive, they involvement has been largely by default. are also phytogeographically and behaviourally different. Thus while I was trained in an agricultural and entomological tradition with a there is this huge flaw at the generic level, can sense ever reign at the totally different and unsophisticated approach to things like taxonomy, species level?
