The sixth species has the stalks branched out much more than in 

 the fifth sort, being weaker and more flaccid: the leaves are longer 

 and more veined: the flowers stand singly upon pretty long pedun- 

 cles, and are not produced in clusters as in that; it is very hairy, the 

 calyx is more swollen, and it flowers a month after it. And Dr. 

 Withering remarks, that the petals on the male plant have the laminae 

 divided down to the claws, but in the female they are only cloven 

 half way down. Dr. John Sibthorp also states, that the capsules 

 in the fifth are roundish, and that its scenlless flowers stand open 

 through the day; while this has conical capsules, and its odoriferous 

 flowers open only towards evening. This also prefers a dry soil, 

 while that spreads in a moist one. It is common in Siberia. 



There are varieties with purple or blush-coloured flowers; wilh 

 quadrifid petals; with hermaphrodite flowers; with double flowers, 

 cultivated in gardens by the name of Double White Bachelor's 

 Buttons. 



Culture. They may be increased with facility in the single sorts 

 by seed, and parting the roots; and in the doubles by dividing or 

 slipping the roots, and sometimes by cuttings of their stalks. 



The seed should be sown in the early spring, as in March, in a 

 bed or border of light earth, in an eastern aspect, each sort separate, 

 raking them in lightly, or they may be sown in small drills. The 

 plants come up in two or three weeks, when they should have occa- 

 sional waterings and hand weedings: and when the plants are two 

 or three inches high, be planted out in beds or borders, in rows six 

 inches asunder, watering them till fresh rooted, letting them remain 

 till the autumn or following spring, when they should be transplanted 

 where they are to remain. 



Both the single and double may be increased by slipping the roots; 

 but it is more particularly applicable to the double sort, as they can- 

 not with certainty be obtained from seed : the season for performing 

 this work is the autumn, after the stalks decay, when the whole root 

 may either be taken up, and divided into as many slips as are fur- 

 nished Avith proper root-fibres, or the main root stand, and as many 

 of the outer offsets as seem convenient be slipped off: these slips,
