Iiaurelia aromatica, Jussieu. 



Southern Chili. A colossal tree, in Valdivia the principal one 

 used for flooring. Wood never bored by insects, and well able to 

 stand exposure to the open air, far superior to that of L. serrata 

 (Bertero), the "Vouvaii or Huahuoa," which tree predominates 

 over L. aromatica in the far south of Chili [Dr. Philippi]. 



Ziaurus nobilis, Linne. 



South-Europe and Asia Minor. The Warrior's Laurel of the 

 ancients, generally called in Britain " Sweet Bay." Greatest 

 height about 60 feet, but always displaying a tendency to oniit 

 suckers and rarely assuming a tree-like character [Loudon]. The 

 leaves are in much request for various condiments, always much 

 sought for packing liquorice, and for their peculiar aroma these 

 Bay-leaves cannot be replaced by any others, unless those of Lin- 

 dera Benzoin and Machilus odoratissima. The berries are used in 

 veterinary medicine. 



Ziavandula angrustifolia, C. Bauhin. (L. vera, De Candolle.) 



The principal Lavender-Plant. Countries around and near the 

 Mediterranean Sea. Of somewhat shrubby growth ; from it, by 

 distillation, the best oil of lavender is prepared ; the English being 

 superior to others. It lives on dry soil, but is less hardy than the 

 following, still it will grow in Norway to lat. 59 55' [Schuebeler]. 

 A thousand plants will yield about two quarts of oil [Piesse]. The 

 plants last only about four years for distillation-purposes. The 

 soil should be calcareous [Vilmorin]. According to Mr. Slater's 

 long experiences at Port Phillip, planting should be effected at the 

 commencement of the cool season, with the prospect of oil to the 

 extent of about 401b. from an acre becoming available in the first 

 season already, worth now about 56s. per Ib. In tropical countries 

 the Lavender likes some shade. 



Ziavandula latifolia, C. Bauble . (L. Spica, De Candolle.) 



South-Europe, North- Africa. This species is the richest yielder 

 of oil. Hardy in Norway to lat. 67 56'. The Lavenders are 

 easily multiplied by slips. Seeds will keep for five years. 



Ziavandula Stoechas, Linne. 



South-Europe, North-Africa, " Topped Lavender." This shrub 

 can also be utilized for oil-distillation and other purposes, for which 

 the two other Lavenders are used. The quality of the oil of these 

 species seems to differ according to their locality of growth. Mr. 

 James Dickinson, of Port Arlington, Victoria, informs us, that this 

 is the best plant known to him for staying sand. It grows much 

 quicker than the Ulex : every seed which falls germinates, so that 

 around each bush every stroke of the spade brings up lots of seed- 

 lings fit for transplantation. In mild regions it is five months in 

 full flower annually, coming into bloom early. Bees are passion-
