3. ^LEPTANDRA. (^Veronica Virginica, L.) 

 Calix 5 -parted, segments accuminiite. Corolla 

 tubular-caiiipamilate, border 4-l()bed, a little 

 ringent, uneq'uil, the lower lamina narrower. 

 Stamina and at length tlie pistilUun much ex- 

 serted; JiUiments below, and tube ot* the ror(jlla 

 pubescent. Capsule ovate, acuminate, 2-celled^ 

 many-seeded, opening at the summit? 



JS*atural Order. — xAntirrhine.e. 



Root perennial; stem angular, (sometimes pentangular) 

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

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

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

 tubular, somewhat caiipanulate, pubescent within; border 

 4-lnbed, the upper lobe somewhat laterally deflected to- 

 wards the filaments of tlie stamina, the three lower lobes 

 coimivent, the central division narrower. iS'f^?72maexserted, 

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

 tlie filaments pubescent, at lengtli divaricate; anthers cor- 

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

 mens, persistent on the fruit, and then exserted longer 

 than the stamens; stigma somewhat capitate, flat, perfectly 

 entire. 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.s 

 and immediately before the genus Pcederota, from which 

 it is readily d'stinguished both by habit and charac- 

 ter, not having a distmctly labiated corolla. In Paderota 

 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.
