* What I conjecture may be the H. caesium of Fries grows, sparingly, 

 on the face of Spindlestone crags. The herbage is a greyish-green, or 

 glaucous ; and the whole plant is thickly clothed with long hairs, patent on 

 the stalks, and erect on the leaves, where each hair arises from a little black 

 point or bulb. The plant is as hairy as any variety of H. pilosella I have 

 seen. 



t The leaves are occasionally variegated in a very beautiful manner by 

 the veins becoming of a rich yellow colour, while the interspaces retain 

 their ordinary green. The colours are distinctly limited, and the effect is 

 striking. Only a few leaves of the bush whence I took my specimens were 

 so marked, and they were quite healthy. I also noticed, in spring, that 

 the leaves of Carex arenaria were, many of them, singularly marked with 

 alternate green and orange-yellow bands. The yellow bands varied fiom 

 ■5th to \ an inch in breadth. The leaves were healthy; and I could discover 

 no cause for the variegation.
