i. H. radicata (Long-rooted Cat's-ear). 

 Leaves all from the root, pinnatifid, with the 

 lobes pointing backwards, bristly ; stalks 

 branched, smooth, with a few scales below 

 the flowers. Well distinguished by its long, 

 branched flower-stalks, which are quite 

 smooth throughout, and slightly swollen be- 

 neath the large yellow flowers, where there 

 are also a few small scales. Hedges and 

 waste places ; common. Fl. July, August. 

 Perennial. 



2. H. glabra (Smooth Cat's-ear). Much 

 resembling the above, but smaller, 3-10 in- 

 ches high ; leaves smooth, oblong ; flower- 

 heads small, yellow ; florets scarcely longer 

 than the involucre. Gravelly places ; not 

 common. Fl. June to August. Annual. 



3. H. macidata (Spotted Cat's-ear). Leaves 

 obovate, not lobed, spreading, rough, spotted 

 above ; stems about a foot high, bearing 



usually 1 (rarely more) large deep yellow flower. Limestone and 

 magnesian hills ; rare. Fl. July, August. Perennial.

 {Long-rooted Cat's-ear) 



7. Lactuca {Lettuce) 



1. L. muralis (Ivy-leaved Lettuce). 

 Florets 5 ; leaves pinnatifid, variously cut, 

 with the terminal lobe largest. A slender 

 plant, leafy below, 1-2 feet high, with 

 small yellow heads, each of which con- 

 tains 5 similar florets, and thus resembles 

 a simple flower of 5 petals. The panicle 

 has a singularly angular growth ; the fruit 

 is black. Woods and old walls ; not 

 uncommon. Fl. July to September. 

 Biennial. 



2. L. scoriola (Prickly Lettuce). 

 Erect, stiff, 2-4 feet high ; leaves usually 

 perpendicular, the lower leaves toothed 

 or deeply pinnatifid ; upper leaves narrow, 

 entire, clasping the stem, leaves with 

 bristles on the under side of midrib ;
