Loganiaceae are a family of flowering plants classified in order Gentianales. The family includes 13 genera, distributed around the world's tropics.
Earlier treatments of the family have included up to 29 genera. Phylogenetic studies have demonstrated that this broadly defined Loganiaceae was a polyphyletic assemblage, and numerous genera have been removed from Loganiaceae to other families (sometimes in other orders), e.g., Gentianaceae, Gelsemiaceae, , Tetrachondraceae, Buddlejaceae, and Gesneriaceae. Some classification schemes, notably Takhtajan's, break the remaining Loganiaceae even further, into as many as four families; Strychnaceae, Antoniaceae, Spigeliaceae and Loganiaceae. Recent DNA studies of the Gentianales have found strong support for the Loganiaceae (as defined here) as a clade containing 13 genera.
Buddleja, or Buddleia () but commonly known as the Butterfly Bush, is a genus of flowering plants. The generic name bestowed by Linnaeus posthumously honoured the Reverend Adam Buddle (1662?1715), a botanist and rector in Essex, England, at the suggestion of Dr William Houstoun. Houstoun sent the first plants to become known to science as buddleja (B. americana) to England from the Caribbean about 15 years after Buddle's death.[more]

The flagtails (ahole or aholehole in the Hawaiian language) are a family (Kuhliidae) of perciform fish of the Indo-Pacific area. The family consists of several species in one genus, Kuhlia, of which, one, (K. rupestris), is freshwater. The others are marine. [more]
