G-lycyrrhiza g-labra Linne. 



South-Europe, North-Africa, South-Western and Middle Asia. 

 The extract of the root of this herb constitutes the ordinary 

 liquorice. The plant grows most vigorously in adequate climes, 

 but requires a deep, rich and friable soil for prolific growth. 

 Propagation best from suckers or cuttings, but a harvest of the 

 roots is only realised in the third or fourth year. The return may 

 come up to as much as four tons on an acre under favourable 

 circumstances. No watering is necessary for this plant. Market 

 value of the root in London now 16s. to 18s. per cwt. [Christy]. 

 Both this and the preceding are hardy in Norway to lat. 59 55' 

 [Schuebeler]. Liquorice is of some utility in medicine, and also 

 used in porter-breweries. Chemical principle : glycyrrhizin. 



CrlyptOStrobus heterophyllus, Endlicher. (Taxodium heterophyllum, 

 Brogniart.) 



China. An ornamental tree, allied to Taxodium distichum in 

 some respects, and like that tree particularly fit for permanently 

 wet ground. The Chinese people plant it along the edges of canals 

 and narrow creeks, the buttress of the tree standing actually in 

 moist muddy soil [Dr. Hance]. 



Gmelina Leichhardtii. F. v. Mueller. 



East- Australia, to 35 S.L. Height of tree to 150 feet ; stem- 

 diameter to 4 feet. Grown now on a commercial scale for fancy 

 timber-purposes in Queensland. Wood of shining paleness, not 

 liable to rend, particularly valued for ship-decks, flooring-boards 

 and superior implements. 



Cronioma Kamassi, E. Meyer. 



South-Africa. This small tree furnishes the yellow Kamassi- 

 wood, much sought for carpenters' tools, planes and other select 

 articles of wood-work, also for wood-engraving, according to Dr. 

 Pappe. Flowers deliciously fragrant. The bark contains a 

 pleasantly bitter tonic principle [Prof. McOwan]. 



CS-ordonia Lasianthus, Linne. 



The Loblolly-Bay. South- Eastern North- America. A handsome 

 tree, growing to a height of 60 feet ; flowers snowy white. The 

 wood is extremely light, of a rosy hue and fine silky texture, but 

 unfit for exposure. The bark is extensively employed for tanning in 

 the Southern States. Available for swampy coast-lands. 



Crossypium arboreum, Linne.* 



The Tree-Cotton. Upper Egypt, according to A. de Candolle, 

 seemingly also Abyssinia, Sennaar and thence to Upper Guinea. 

 A tall perennial species, but not forming a real tree, yielding cotton 

 in the first season. Leaves long-lobed. Bracts with few teeth.
