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.

Sect. Char. Calyx of 5 sepals ; outer sepals narrow, minute ^ inner ones 

 4-veined. Petals yellow, small, scarcely twice the length of the sepals. 

 Style twisted at the base, and bent inwards at the apex, usually shorter than 

 the stamens, rarely longer. Stigma capitate, 3-lobed. Capsule small. 

 Seeds few, rather rufescent. Perennial herbs or subshrubs. Leaves 

 stalked, feather-nerved, opposite, usually without stipules, rarely with 

 stipules at the summits of the branches. Flowers second, racemose* or pa- 

 nicled. Pedicels bracteate at the base, recurved before flowering, when in
