6 DIANDRIA MONOGYMA 



smooth; stem*leares pilose ; lower ones often opposite, broad or round-ovate, mostly 

 •5-lobed, middle lobe largest ; upper ones alternate, 3-lobed. Peduncles longer than 

 the leaves. Corollu blue, shorter than the calyx. Cajisule ventricose. 



Hab. Along Ridley Creek, near J. Garrett's : rare. Ft. April. Fr. May. 



Obs. Probably introduced from Europe. This species was found, and brought 

 tx> me in 1831, by Mr. G120. W. Hall,— a gentleman to whose Botanical zeal, and 

 unwearied industry in exploring the eastern portion of the County, I am indebted 

 for a considerable number of the plants which have been detected since the publi. 

 cation of my Catalogue. 



Two or three other species, of this numerous genus, have been found in the Uni- 

 ted States ; one of which Pursh describes as a native.

[Greek, Leptos, slender, and Aner % andros male; in reference to the stamens.] 



Calyx 5-parted ; lobes acuminate. Corolla tubular-carapanulatc, 

 unequally 4-lobed, somewhat ringent. Sta?nens, and finally the pistil, 

 much exserted. Capsule ovoid, 2-cclled, many-seeded.

Vihoinian Leptandha. Vulgo — Tall Speedwell. 



Root perennial. Stem simple, obtusely angular, smooth, 2 to 5 feet high. Leaves 

 in verticils— gonerally 4 or 5, occasionally 6, sometimes only 3,— si: bsessile, taper- 

 ing to a sharp point, acutely serrate, glaucous beneath, and hairy along the 

 nerves. Flowers subsessile, in long terminal, subterminai and verticillate, spikes. 

 Bracts small, acuminate. Corolla white, tubidar, pubescent within. Capsule ob- 

 long-ovoid, 2-celled ; valves inflected, forming the dissepiment,-— (each valve appa- 

 rently composed of two, united by a suture,—) opening at summit into four teeth, 

 or segments. 

 Hab. Rich low-lands, and borders of woods : frequent. Fl. July. Fr. September. 



Obs. The only species of the genua, known in tho U. States. It formerly be- 

 longed to Veronica; but its striking difference lorn* ago induced C olden, and after- 

 wards Rafinesque, to propose it as the type of a distinct genua, ii was separated 

 by Nuttall, in 1818. 



6. UTRICULARIA. L. JYutt. Gen. 19. 

 £Lat. Ulriculus, a little bottle ; from the Inflated appendages to the floating roots.] 



Calyx 2-parted ; lips undivided, nearly equal. Corolla personate, or 

 irregularly bilabiate ; upper lip erect, lower one spurred at base ; palate 

 subcordatc. Filaments incurved, bearing the anthers within the apex. 

 Style short; stigma bilamellate. Capsule globose, 1 -celled, many 

 seeded.

 resembling leaves, often much divided, and bearing little vesicles, Kot. Ord, 206.
