ACANTHACEjE. 



354. Justicia brachiata, Pursh fl. i. p. 13. On the 

 Arkansa ? 



Obs. Our specimens agree in almost every character with 

 the description of Pursh, except that the stem is a little hairy. 

 Upper lip of the corolla entire ; lower 3-toothed. It con- 

 nects the present genus with Diclyptera, and is allied to D. 

 multiflora of Kunth, syn. ii. p. 34. Besides this species there 

 were specimens of another in the collection, which could 

 not be determined for want of the flowers. The following 

 are some of the principal characters. J. caule fruticoso, 

 brachiatim ramoso, ramulis pubescentibus ; foliis ovalibus 

 brevi-petiolatis, acutis, integerrimis subtus ad venas hirsutis, 

 ciliatis ; pedunculis axillaribus, 1 — 2-floris, bracteis lineari- 

 lanceolatis, acutis ; laciniis calycinis subulato-filiformibus, 

 ciliatis, fructu duplo longioribus ; fructibus oblongis, utrin- 

 que attenuatis, bilocularibus ; loculis 2-spermis ; seminibus 

 lenticularibus, hispidis.
