Justicia tobagensis is a species of plant in the family Acanthaceae which is endemic to Trinidad and Tobago. The species is only known from two areas in the Main Ridge of Tobago. ^[3] It was first described as Drejerella tobagensis by German botanist Ignatz Urban in his Symbolae Antillanae, based on a collection made by Danish botanist Henrik von Eggers. ^[4]

In 1995 American botanist Dieter C. Wasshausen proposed a new combination, Justicia tobagensis, which reflected the predominant view that the genus Drejerella is actually a part of the genus Justicia. ^[5]

Conservation status

Although Justicia tobagensis is not listed in the IUCN Red List, the authors of a 2008 assessment of the endemic plant species of Trinidad and Tobago considered it vulnerable due to the fact that it is known from a restricted area or small number of localities. ^[3]
