The blade of the leaf is of a darker color than the midrib. The color 

 of the blade is Ridgway's varleys green, 31' m. The midrib is covered 

 on both upper and lower surfaces with hairy pubescence. The lobes 

 are usually widest at the base, often having a minor lobe attached to 

 the proximal edg^e of the base of the major lobe. Attached to the 

 midrib between the lobes is a narrow wing. The lobes are usually 

 close together, with the terminal lobe slender and pointed. 



H6 RACE 

 Plate 45, figure 2 



The H6 race was isolated in 1919 from a Berkeley Crepis stock. 

 The size of the rosettes is more variable than in viridis, the rosettes 

 ranging from 8 to 12 inches in diameter. The leaves are pinnately 

 and bipinnately lobed ; the lobes are constricted at the base and 

 rounded at the tip, and inclined to twist, so that the plane of the lobe is 

 not in the same plane with the midrib. Anthocyanin is conspicuously 

 present. There are no hairs on the midrib. The lobes, usually six 

 in number, are widely spaced. The terminal lobe is large and blunt- 

 tipped. The narrow wing on the midrib is crimped, presenting a 

 ruffled effect. The wing and edg'es of the lobes contain a blackish 

 purple coloring which appears very earh^ in the development of the 

 plant. The leaf color, according to Ridgway's Standard, is cedar 

 green, 31m. The characters which make up this type are dominant, 

 excepting smooth ribs, when crossed with viridis. 



PALLID 

 Plate 45, figure 1 



This race was obtained in 1919 by inbreeding in the same Eureka 

 stock that produced the viridis race. The rosettes are from 6 to 10 

 inches in diameter. This race produces more leaves in the rosette 

 than do the preceding races, giving the rosette a thick mat -like appear- 

 ance. Pallid lacks anthocyanin and is a much paler green (Ridgway's 

 forest green, 29'm.) than the two races described above. The lobes 

 are broadest at the base, are set closely together, and have pronounced, 

 pointed teeth. This race does not grow so rapidly as the darker green 

 races. Rib hairs are present on the midrib.
