Mazaceae

Mazaceae

This family, traditionally accommodated in Scrophulariaceae, was transferred to Phrymaceae (APG III 2009) as a result of molecular phylogenetic studies. However, more recent studies by Reveal (2011) tend to accept Mazaceae as a family of its own (see also APG IV 2016). According to Barker & al. (2012) Mazaceae, as described by Reveal l.c., includes two genera: Mazus Lour. and Lancea J.D. Hook. & T. Thomson. Plants of the latter two genera, however, have bilamellate, sensitive stigmas like the Phrymaceae and Reveal's brief description of Mazaceae does not distinguish it morphologically from Phrymaceae. However, although these authors did not find apomorphies to distinguish Mazaceae from Phrymaceae, it seemed likely that further morphological studies will corroborate the distinction between Mazaceae and Phrymaceae. Both families are therefore accepted as separate entities in this account.
