the autumn, and either to pot them or place them in a box 

 of dry sand or mould during winter, secured from frost and 

 damp. 



The plant flowers from the middle of August to the end 

 of September in any good soil, particularly if a little peat 

 and sand be added. Like many Mexican Composite it 

 flowers so late that it seldom ripens seeds in the open border, 

 but a few plants kept in the green-house will do so ; it is 

 only by seeds that the species can be increased with any cer- 

 tainty. 



The seeds should be sown about the end of March in rich 

 soil, on a nearly exhausted hot-bed, and treated like those of 

 half-hardy perennials ; keeping them in pots the first season, as 

 they will* not flower before the second year. The seedlings 

 must not be planted out in the open border before the middle 

 of May. 



Fig. 1. is a floret of the ray with a nearly smooth achse- 

 nium, and a tooth-like lobe proceeding from the inner edge 

 of the mouth of the tube. Fig. 2. is a floret of the disk, with 

 a scale of the receptacle; the former has a tomentose ovary, 

 and a corolla whose tube is contracted just above the base, 

 and then ventricose above the contraction.
