Tradescantia sect. Zebrina (Schnizl.) D.R.Hunt, Kew Bull. 41(2): 404. 1986.   Fig. 7 View Figure 7


The section is characterized by perennial herbs, with thin fibrous roots, definite or indefinite base, without rhizomes, leaves with symmetric to asymmetric base, inflorescences terminal or axillary, pedunculate, cincinni bracts spathaceous, bracteoles conspicuous and linear, flowers tubular, sepals unequal, basely to completely conate, keeled or not, petals free or conate, long-clawed, stamens 6 and subequal, epipetalous, filaments straight at post anthesis, medially sparsely bearded with moniliform hairs, connectives sagittate to linearly-tapered, anther sacs round, ovary glabrous, stigma capitate, seeds rugose, embryotega inconspicuous and semilateral (Hunt 1986; Pellegrini 2015).


Tradescantia sect. Zebrina   is a small group, composed of ca. five species, ranging from Mexico to Venezuela. Tradescantia zebrina   Heynh. ex Bosse is widely cultivated worldwide, and occurs in Brazil as an invasive species (Hunt 1986; Pellegrini 2017). As aforementioned, the section is small but morphologically diverse, being poorly differentiated from T. sect. Campelia   and T. sect. Corinna   . As stated by Hunt (1986), these three sections seem to blur into one another, with several species being originally assigned to one group and subsequently transferred to another.
