yellow, closing in the afternoon. Cal. rough with black as well 

 as white bristles. Scales of the receptacle long, narrow, and mem- 

 branous. Seeds, according to Linnaeus, wrinkled. 

 Linnaeus, as well as Haller, confounded this species with H. helve- 

 tica of Jacquin, Haller's n. 2 ; but the real maculata was also 

 found in Switzerland by Mr. Davall.

Annual. June — August. 



Herb milky and bitter, extremely variable in luxuriance, of a bright 

 shining green, and almost perfectly smooth. Stems numerous, 

 hollow, smooth ; the first or central one simple, straight, leaf- 

 less, bearing a solitary flower ; the rest rather spreading, or 

 partly recumbent, branched, wavy, slightly leafy, from 6 to 12 

 or 1 8 inches high. Leaves numerous at the root, oblong, or 

 tongue-shaped, deeply toothed, or slightly sinuated, occasion- 

 ally fringed or partially hairy ; those on the stem smaller, alter- 

 nate, sessile. Fl. on terminal stalks, solitary, small, bright yel- 

 low, open in the morning only. Cal. slender, smooth, glaucous 

 or purplish ; the scales flat, regularly imbricated, finally re- 

 flexed. Seeds slender, dark brown, finely striated, rough like the 

 down and its stalk, which latter part is wanting in those of the 

 circumference. Scales of the receptacle very thin and membra- 

 nous, with taper points on a level with the seed-down, deciduous. 



Haller long overlooked this species in Switzerland, nor was it at 

 all well known to British botanists till Mr. Curtis's excellent 

 figure and description appeared. In the early part of the day, 

 turnip fields are visibly bespangled with its bright blossoms ; 

 but after they close it is less readily observable. The synonym 

 of Columna, though cited by Ray, has been generally neglected.
