gardeners to an ulceration of the stems 

 of seedlings, and other tender plants. 

 This ulceration arises from the soil and 

 air ill which they are vegetating being 

 kept too moist or damp. Flower seed- 

 iiugs are especially liable to he tlras 

 affected; and, to prevent this, one third 

 of the depth of the pot should be filled 

 with drainage, and the soil employed, 

 instead of being sifted, allowed to retain 

 all moderately-sized stones. The seeds 

 should be sown very thinly, pressed 

 down, and a little white sand be sprinkled 

 over the surface, because this is not 

 easily disturbed by watering, and is not 

 a medium that retains moisture to the 

 neck of the seedlings, where dampness 

 most affects them. A pot of sand should 

 be kept hot, and whenever symptoms of 

 the disease appear, a little whilst hot 

 sprinkled on the soil.

This small order consists of Fern-like plants, 

 and for all the purposes of cultivation may be 

 considered as Ferns. Stove herbaceous peren- 

 nial. Divisions ; peat and loam. Summer temp., 

 60 to 90 ; winter, 48 to 55.

DA'PHNE. (So called after the fabled 

 nymph of that name. Nat. ord., Daph- 

 nads [Thymelacese]. Linn., 8-Octandria

Extreme causticity is the general property of 

 the Daphnads the Spurge Laurel and Mezereum 

 particularly so. Seed for most of the species, 

 especially of the D. luum'ola, or Spurge Laurel ; 

 used as a grafting stock for most of the rarer and 

 tender kinds. As the seed is two years in vege- 

 tating, it is usual to keep it some time in sand, 

 in aheap. D, cneo'rum and other d'.varf kinds, 

 especially if at all trailing, are generally propa- 

 gated by layers in summer. A close pit for graft- 

 ing the finer kinds, in March or April, is an ad- 

 vantage. Most of them like a good proportion of 

 sandy peat ; but the deciduous Meze'reum prefers 

 pure loam. The odo'ra and odo'ra ru'bra are 

 nearly hardy in the climate of London ; but farther 

 north they require the cold pit or greenhouse.
