Sen ceio — Seseli — SilpJi iu m. 187 



green, roughish, lobed leaves. It requires a substantial, 

 but free and cool soil, and may be multiplied at almost 

 any season by cuttings. It requires greenhouse pro- 

 tection in winter, grows freely in the open air planted 

 out in early summer, and is suitable for beds or groups 

 associated with the medium-sized subjects. 



* Seseli gummiferum. {Silvery Seseli). — An umbel- 

 liferous plant with elegantly-divided leaves of a peculiarly 

 pleasing glaucous or almost silvery tone. I am not sure 

 whether this plant is perennial or not, and it is not hardy 

 on cold soils, having perished during several of our most 

 severe winters, but it is so unique in its way that some 

 persons might like to grow it, and if so the best position 

 is on dry and sunny banks, or raised beds or borders. It 

 is one of the few subjects that are at once fern-like and 

 silvery, and if plentiful enough might be used to form 

 charming edgings. It is not difficult to raise from seed, 

 which should be sown soon after being gathered. As it 

 is liable to perish in winter, perhaps the best way to deal 

 with it would be to put it out annually at the end of 

 spring, raising it and keeping it in frames for this pur- 

 pose ; and to secure seeds a few plants might be left in 

 10 in. or 12 in. pots, so that the seed might be gathered 

 under cover. Doubtless, however, continental raisers 

 can supply it. S. Russia. 



*Silphium integrifolium. — This composite has a 

 rough, vigorous, rigid, slightly four-angled, grooved stem, 

 from 2 ft. to 4 ft. high, and leaves from 3 ins. to 5 ins. 

 long, all opposite, lanceolate-ovate, entire, tapering to a 

 sharp point from a roundish heart-shaped and partly- 

 clasping base, and covered with a roughish down. The
