rowed at base : calyx-lobes from linear to spatulate or oblong, mostly equalling and some- 

 times exceeding the^ube : corolla light blue, an inch or more long, its broad and roundish 

 short lobes erect, little and often not at all longer than the 2tclcf t and many-toothed inter- 

 vening appendages : seeds nearly as in the preceding. — Spec. i. 228 (Moris. Hist. iii. 484,

 G. Andrewsii, Griseb. Stems stout, a foot or two high, smooth : leaves from ovate- to 

 broadly lanceolate, gradually acuminate, contracted at base, 2 to 4 inches long: calyx- 

 lobes lanceclate to ovate, usually spreading or recurved, shorter than the tube : corolla as 

 the preceding but more oblong and the lobes obliterated or obsolete, the truncate and 

 usually almost closed border mainly consisting of the prominent fimbriate-dentate inter- 

 vening appendages: seeds with a conspicuous wing, oblong in outline. — Gent. 287, & in

 south to the upper parts of Georgia. Corolla from bright to pale blue, with white plaits, 



' sometimes all white. 



= = Calyx-lobes and bracts (also leaves) smooth and naked on the margins (or sometimes very 

 minutely ciliolate-scabrous under a lens, especially the lower part of the bracts): seeds distinctly 

 willed: flowers in a leaf\ r -involucrate capifate cluster, and often bolliaiy or clustered in upper 

 axils. 



G. alba, Muhl. Smooth throughout: stem stout, 2 feet high: leaves ovate-lanceolate or 

 oblong-lanceolate and gradually acuminate from a cordate-clasping base, 2 to 4 inches 

 long : flowers usually rather numerous in the compact terminal cluster : calyx-lobes ovate 

 or subcordate, acute, reflexed-spreading, shorter than the tube : corolla dull white and 

 commonly tinged with yellowish .or -greenish, gften an inch and a half long, like that of 

 G^Saponaria, but more campanulate and open ; its ovate lobes twice the length of the 

 broad and erose-toothed appendages. — Cat. ed. 2, 29, & Fl. Lancast. ined. ; Nutt. Gen.

 leaves linear or narrowly lanceolate, 1-J- to 3 inches long, 2 to 5 lines wide, and with some- 

 what narrowed base : flowers 1 to 5 in the terminal involucrate cluster, and often solitary in 

 one or two axils below : calyx-lobes linear or lanceolate, shorter than the tube : corolla blue, 

 an inch or more long, narrow-funnelf orm ; the erect lobes roundish-ovate and obtuse, 2 lines
