Lectotypifications.

In choosing a lectotype for Justicia lineolata Ruiz & Pav. we have simply chosen the most complete specimen at MA. Lindau cited two specimens of Justicia flavidiflora , Ule 5699 and Poeppig 1813, both stored presumably at Berlin and both destroyed in 1943. Poeppig 1813 was collected at “ Maynas prope Tocache ”, so presumably from San Martin in Peru. We have been unable to trace any duplicate or image of this specimen, so have selected the Hamburg collection of Ule 5699 as the lectotype, this specimen already annotated (but unpublished) as lectotype by Wasshausen.

Notes.

This species is very well named. The cystoliths are numerous giving the plant a bluish-green appearance when dry, often facilitating the identification of poor or even sterile material.
