Nees (in DC, Prod. xi. 397) joined this plant with a Senegambian plant, probably 

 J. Galeopsis^ T. Anders., with which this species might be united. I have not found 

 the scrap of U. Don's collecting which Bentham (in Hook. Niger Fl. 483) thinks may 

 have been Adhatoda Koischyi^ Nees. It was by some slip that T. Anders, reduced 

 this species to J. palustris, T. Anders., which has (as T. Anderson sa^s) "flowers 

 in terminal spikes." 



38. J, filifolia, Lindau in Engl. Jahrb. xx. 70. Straggling, 

 sparingly hairy; branches elongate with long internodes. Leaves 3 in. 

 long, lanceolate and ovate-lanceolate, nearly glabrous ; petioles up to 

 li- in. long ; upper leaves (sometimes nearly all the leaves) narrow, 

 linear-oblong or oblong, J-J in. broad. Flowers 1-3 together in the 

 distant axils, often surrounded by several shortened floral leaves 

 \—\ in. long, elliptic or orbicular. Sepals ^ in. long, narrow-lanceolate, 

 acute, hispid. Corolla \—^ in. long, white with purple marks. Ovary

Last's specimen, from which Lindau described, has lost all the lower leaves, the
