9, are merely naturalized, the rest natives, common to 

 Europe and America. 



12. ^LEPTANDRA. (^Veronka Virginica, L.) 

 Calix 5-parted, segments accuminate. Corolla 

 tubular-campanulate, border 4-lobed, a Jittle 

 rirjgeiit, unequal, the lower lamina narrower. 

 Stamina and at length tiie pistUlum mtjch ex- 

 serted; filaments below, and tube of the corolla 

 pubescent. Cajjsule ovate, acuminate, 2-celled^ 

 many-seeded, opening at the summit? 



JS'*atural Order. — Antirrhine^. 



Root perennial; stem angular, (someiimes pentangular) 

 tall. Leaves verticillate in 4s, 5s, and 6s, never simply op- 

 posite or ternate. Flowers in very long and dense spikes; 

 spikes aggregate, nearly terminal. Calix 5-parted. Flowe-s 

 lubular, somewhat canipanulate, pubescent within; border 

 4-l()bed, the u])per lobe somewhat laterally deflected to- 

 wards the filaments of the stamina, the three lower lobes 

 f.onnivent, the central division narrower. Stamina exserted, 

 regarding the upper lobe af the corolla, the lower part of 

 the filaments pubescent, at length divaricate; anthers cor- 

 date-oblong, 2-celled. Stijle at first shorter than the sta- 

 mens, persistent on the fruit, and then exserted longer 

 than the stamens; sti^-tna somewhat capitate, flat, perfectly 

 tntire. Capsule ovate, acuminate, a little compressed at 

 the summit, with 2 marginal nerves contrary to the disse- 

 piment, valves with inflected margins contiguous to the 

 seminal placenta, which occupies the place of a dissepi- 

 ment, valves 2, only opening about half way down; seeds 

 numerous, ovate? 



From this examination it will be evident that the pre- 

 sent plant does not appertain to the same order as 

 Veronica^ but arranges directly with the Antirrhine.* 

 and immediately before the genus Pcederota, from which 

 it is readily distinguished both by habit and charac- 

 ter, not having a distinctly labiated corolla. In Pxderota 

 also, the corolla is somewhat rotate, the upper lobe gen- 

 erally emarginate, the filaments shorter than the corolla, 

 and the anthers converging as in many didynamous flow- 

 ers.
