SCROPHULARINE^. 

 Angelonia integerrima, Spreng., Syst. Cur. Post., 235. 



Asuncion (21*7). December.- = Balansa 2145. 



We have nothing resembling this genus in our country. Stem 

 frutescent, 1 m. or more in height, glabrous, ascending or erect; 

 Leaves opposite, entire, oblanceolate or lanceolate, acute or o})tuse 

 at the apex, sessile, 5-12 cm. long. Flowers blue, in long, terminal 

 racemes (3 dm. or more). Calyx of 5 small, green sepals with 

 membranous edges, closely appressed and about J as long as the 

 corolla, persistent in fruit. Corolla ventricose, gibbous at base, not 

 quite 1 cm broad, 5-lobed, the 4 lower lobes rounded and reflexed, 

 the 5th a broad, keeled hood with 2 folds on the outside at the upper 

 part, which are greenish at the top and in the interior. Hood sur- 

 mounted by an erect lobe crimped below and with a white projec- 

 tion at base inside, prettily spotted with white and blue on the 

 lower side. Stamens 4, inserted on the corolla near the base ; 

 anthers with 2 divaricate cells, opening by slits at the top, their 

 edges blue ; filaments blue at the base. Fruit a large, ovoid, pointed 

 capsule. It is almost impossible to convey any intelligible idea of 

 this curious flower by description. It is not only curious to the 

 stranger from northern climes, but very beautiful.
