(Paleacrita vernata Peck) does much harm to apple, elm, cherry, and 

 some other trees. The females are wingless and it is thought that the 

 chief means of distribution is by the eggs on nursery stock. In the 

 majority of cases the canker worms are limited to orchards which are 

 neglected as to spraying and cultivation. The life-history is as follows. 

 The larvae feed on the leaves in spring and then enter the soil to a depth 

 of 2 to 5 inches, pupating in an earthen cell. The imagos appear in 

 spring or during mild spells in winter, the female climbing up the tree to 

 deposit her eggs in irregular masses under loose bark scales, in cracks in 

 the bark or other such places. It is recommended that the trees should 

 be sprayed with an arsenical spray (1 lb. for each 100 gallons to which 

 milk of lime made by slaking 4 to 5 lb. of stone lime should be added) ? 

 or arsenate of lime may be used at the rate of 6 to 10 lb. to 100 gallons 

 of water or Bordeaux mixture. Two applications should be made, the 

 first when the fruit buds are exposed, the second after the blossoms have 

 fallen. This will serve to lessen both the canker worm and codling 

 moth. The orchard should be ploughed and cultivated. To catch the 

 females grease bands should be applied in the spring, made from printer's 

 ink, tar, bird-lime, &c, spread on strips of paper 5 or 6 inches wide and 

 long enough to go around the tree-trunk. The same methods are, of 

 course, applicable in control of our winter moths. — F. J. C. 



Canna flaccida. By B. Othmer (Die Gart. No. 22, p. 254; 

 February 29, 1908). — A native of Florida and South Carolina. A water- 

 side or bog plant, recommended for its handsome foliage, for warm

Cape Ivy (Senecio scandens, DC). By Ad. van der Heede (he 

 Jard, vol. xxii. No. 501, p. 8 ; January 5, 1908 ; 1 plate). — Senecio 

 scandens, formerly known as Delairea scandens or D. odorata, is an 

 attractive climbing plant with yellow flowers, which, unlike many Com- 

 positae, have an agreeable scent. Its succulent green leaves resemble 

 ivy. It grows freely in a cool house or winter garden, but must be kept 

 dry and in the full light in winter. S. scandens is a native of the Cape ; 

 S. macroglossus, with much larger flowers, of Port Natal. There is also 

 a variegated variety. — F. A. W. 



Capraria frutescens. By J. Britten (Jour. Bot. 537, pp. 314-315 ; 

 9/1907). — This is the correct name of the plant collected at Vera Cruz 

 by Houstoun, called Erinus frutescens in Miller's " Dictionary " (1768), 

 C. cuneata in " Hortus Kewensis," ed. 2, G. saxifragaefolia in " Bot. Biol. 

 Centr.Amer.," and Pogostoma saxifragaefolia in the " Prodromus." Erinus 

 tomentosus of Miller, Stemodia lanata of the " Prodromus," from the same 

 place, is S. tomentosa by the new rules. — G. S. B. 



Carbolineum as a Remedy for Woolly Aphis, Canker, and 

 Rust (Neueste Versuche mid Erfahrwigen mit dcm Karbolineum). 

 Von R. Betten (Herausgeber des Erfurter Fiihrers in Obst- und Gartenbau 

 in Erfurt. 85 Pfg.). — An article in the second January number of 

 " Gartenflora "calls attention to this pamphlet on the value of Carbolineum 

 as an insecticide and fungicide.— If. B. D.
