Naturalisation in Extra-Tropical Countries. Ill 



Ceanothus rigidus, Nuttall. 



California. One of the best of hedge-shrubs, available for dry 

 situations. Evergreen; to 12 feet high; the branches becoming 

 densely intricate. In the coast-tracts it is replaced by C. thyrsiflorus 

 (Escholtz), which can also be used for hedges and copses, and will 

 live in mere coast-sand. C. prostratus (Bentham) forms natural 

 mats on slopes, made by roads and slides, which it gradually covers, 

 and with its pretty blue flowers soon decorates [Professor Bolander]. 

 Irrespective of their beauty, the different species are worthy of 

 cultivation as forming excellent wind-breaks. A fair tea is made 

 from the leaves of C. velutinus [Dr. Gibbons]. Some species are 

 relied on as forage-plants. 



Cedrela Australia, F. v. Mueller.* 



Eastern Australia, as far south as 36. The Australian Red Cedar 

 or Cedrel. Foliage deciduous in cool regions. Attains a height of 

 200 feet and sometimes a stem-girth of 18 feet near the base. Messrs. 

 Danger and Name measured a tree on the Macleay-River, 48 feet in 

 stem-circumference at 10 feet from the ground: it yielded 80,000 feet 

 of sound timber. Rev. Dr. Woolls noted also in New South Wales 

 trees so large as to yield 30,000 feet (superficial) of timber. Market- 

 value in Brisbane 7 10s. to 8 10s. per 1,000 superficial feet. The 

 light, beautiful wood is easily worked and susceptible of high polish; 

 it is very much in request for furniture, for turnery including stetho- 

 scopes, for the manufacture of pianofortes, for boat-building, frames 

 of window-blinds, cigar-boxes and a variety of other joiners' work ; 

 thus it is highly prized for building racing boats, which weigh little 

 over 30 Ibs., though 30 feet long, and yet prove durable [S. Ed- 

 wards]. The timber from the junction of the branches with the 

 stem furnishes choice veneers. Altogether the wood is much less 

 liable to be bored by insects than most others. The bark contains a 

 considerable quantity of tannin, which produces a purplish leather 

 [Fawcett]. This tree is hardy at Melbourne, but of slow growth in 

 open exposed gardens and poor soil there. 



Cedrela Bogotensis, Triana and Planchon. 



New Granada, ascending to 8,500 feet, therefore unusually hardy. 

 The timber of this tree is there most extensively in use [Prof. 

 Sodiro]. , 



Cedrela febrifuga, Blume.* 



Java, Sumatra, Timor, in cooler mountain-regions. More closely 

 allied to C. Australis than to C. Toona. A tree, rising finally to a 

 height of 200 feet. Bark of tonic property. Hasskarl further notes 

 from Java C. Teysmanni and C. inodora. Cedrelas occur also in New 

 Guinea.
