Watery and marshy places. On rocks in the bed of the Dargle 

 river, abundant. Fl. all the summer. If .Readily distinguished by 

 Hs more glossy, shining leaves, and more slender habit than the pre- 

 ceding. It is, however, doubted by many acute Botanists whether it 

 should be considered a distinct species from the last. 



32. CREPIS. Linn. Hawk's-beard. 



Involucre tumid at the base, surrounded with deciduous scales, 

 ribbed and furrowed, (often very obscurely). Receptacle 

 naked. Pappus simple, sessile. Name ; Kprj-ms, a slipper or 

 last in Greek, but why applied to this plant is not known.

 11 Calyx equal in length to the pappus ; leaves glabrous, lanceo- 

 lato-runcinate or remotely dentate, cauline ones with their 

 margins flat ; fruit oblong, with smooth ribs, shorter than the 

 pappus." Babingtons MSS. C. tectorum, Br. Fl. 1. p. 347. 

 E. Fl. v. iii. p. 372. E. Bot. t. 1111. 



Meadows, pastures, and waste ground, frequent. Fl. July. . Very 

 variable in size and luxuriance, from 1 2 feet high, generally of a fine 

 deep shining green, nearly smooth, except the calyx which is more or 

 less downy and glandular ; leaves smooth, variously runcinate or jagged, 

 the upper ones dilated and clasping at the base, where also they are 

 mostly toothed. I have adopted the name lately given to this plant by 

 Mr. Charles C. Babington, of St. John's College, Cambridge, it being 

 now considered by him and others to be C. virens of LinncBUS. The 

 C. tectorum of foreign authors which has not yet been found in Bri- 

 tain, is described as having the leaves sinuato-pinnatifid, the fruit ob- 

 long, attenuated, with rough ribs, equalling the pappus ; whereas our 

 plant has the fruit smooth, oblong, shorter than the pappus. 



2. C. biennis, Linn. Rough Hawk's-beard. " Calyx shorter 

 than the pappus ; stem and runcinato-pinnatifid ; leaves rough ; 

 fruit linear-oblong, attenuated, with rough ribs equalling the 

 pappus." Eab.Br.Fl.l.p.347. E. Ft. v. iii. p. 373. E.

Sandy fields and ditch banks. Plentiful near Kilbarrick and Bal- 

 doyle, at Portmarnock and other places on the northern side of Dublin. 

 Fl. June, July. $ . Stems 2 4 feet high, furrowed, rough above. 

 Lobes of the leaves toothed. Flowers much larger than in the pre- 

 ceding. Involucre downy and somewhat bristly. Pappus very white, 

 crowning the much elongated fruit.

 large, lax, leafy ones. Receptacle naked. Pappus feathery,
