338 ARBORETUM AND FRUTICETUM. PART Ill. 
clammy, somewhat cinereous, opposite, upper ones alternate. Lower 
stipules minute, the rest long and loose, Peduncles and calyxes villous, 
clammy. Petals distinct. (Don’s Mill. i. p. 308.) Found within the south 
of France and Spain, and introduced in 1790. It is a slender plant, growing 
about 1 ft. in height, and producing very small pale yellow flowers from 
May to September. It is a distinct sort ; and, though not very ornamental, 
it is valuable on account of its flowering the whole summer. Its flowers 
are very fugacious, the petals expanding in the morning, and dropping before 
the middle of the day.
