TABLE 1 in A review of the infrageneric classifications proposed for Kalanchoe (Crassulaceae subfam. Kalanchooideae) from the earliest times up to 2000

TABLE 1. Summary of the infrageneric classifications systems proposed for Kalanchoe that are reviewed in this paper. Some of the classifications, proposed since the genus was described in the 18 th century, up to 2000, were only rudimentarily presented by the respective authors. Each of the classifications is discussed in detail in the main text.
