Malvales lightness, and that of "Tilia" (lime, linden, or basswood) as a popular wood for carving. Fruit of the cacao tree ("Theobroma cacao") are used as an ingredient for chocolate. Kola nuts (genus "Cola") are notable for their high content of caffeine and, in past, were commonly used for preparing of various cola drinks. Other well-known members of Malvales in the APG II sense are daphnes, hibiscus, hollyhocks, okra, baobab trees, cotton, and kapok. The morphology of Malvales is diverse, with few common characteristics. Among those most commonly encountered are palmate leaves, connate sepals, and a specific structure and chemical composition
Theobroma cacao up to 8% of cacao pods dry weight. The cacao genome appears close to the hypothetical hexaploid ancestor of all dicotyledonous plants, and it is proposed as an evolutionary mechanism by which the 21 chromosomes of the dicots' hypothetical hexaploid ancestor underwent major fusions leading to cacao's 10 chromosome pairs. The genome sequence enables cacao molecular biology and breeding for elite varieties through marker-assisted selection, in particular for genetic resistance to fungal, oomycete and viral diseases responsible for huge yield losses each year. In 2017-18, due to concerns about survivability of cacao plants in an era of global warming in
