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

 times exceeding tlie tube : corolla light blue, an inch or more long, its broad and roundish 

 sliort lobes erect, little and often not at all longer than the 2-cleft and many-toothed inter- 

 vening appendages: seeds nearly as in tlie preceding. — Sjitc. i. 228 (Jloris. Hist. iii. 4yi,

 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 inclies long : calyx- 

 lobes lanceclatc 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 wmg, oblong in outline. — Gent. 287, & in

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

 minutely ciliolate-scabrous under a lens, especially the lower part of tlK- bl■at■t^) ; seeds distinctly

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

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

 C. Siijjoiiaria, hut more campanulate and open; its ovate lobes twice the length of the 

 broad and erose-toothed appendages. — Cat. ed. 2, 20, & 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 : caly ,x-lobes linear or lanceolate, shorter than the tube : corolla blue, 

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