IN EXTKA-TROPICAL COTJNTKIES. S21 



Tynoon glaudulosum, A. de Jussieu. 



New South Wales and South Queensland. This evergreen 

 tree deserves cultivation in sheltered warm forest-valleys on 

 account of its rose-coloured wood. Some species of Dysoxylon 

 of East Australia produce also rosewood. 



Tacca pinnatifida, G. Forster. 



Sand-shores of the South Sea Islands. From the tubers of 

 this herb the main supply of the Fiji arrowroot is prepared. 

 It is not unlkely that this plant will endure a tempera te 

 clime. The • Tacca starch is much valued in medicine, and 

 particularly used in cases of dysentery and diarrhoea. Its 

 characteristics are readily recognised under the microscope. 

 Several other kinds of Tacca are distinguished, but their 

 specific limits are not yet well ascertained. Dr. Seemann 

 admits two (T. maculata and T. Brownii) for tropical Australia, 

 one of these extending as a hill plant to Fiji. From the leaves 

 and flower-stalks light kinds of bonnets are plaited. A Tacca 

 occurring in the Sandwich Islands yields a large quantity of 

 the so-called arrowroot exported from thence. Other species 

 (including those of Ataccia) occur in India, Madagascar, 

 Guinea, and Guiana, all deserving tests in reference to their 

 value as starch plants. 



Tagetes glanduligera, Schranck. 



South America. This vigorous annual plant is said by Dr. 

 Prentice to be palicifugous. 



Taliunm patens, Willdenow. {T. j)aniculatum, Ga-ertner.) 



From Mexico to Argentina. A perennial succulent herb, 

 which might easily be naturalised on coast rocks. It furnishes 

 the " Puchero " vegetable. 



Tamarindus Indica, Linne. 



Tropical Asia and Africa. This magnificent, large, expansive 

 tree extends northwards of Egypt, and was found by the 

 writer of this list in North- Western Australia. Final girth 

 of stem 25 feet not rare. Never leafless. Varieties occur, 

 according to Brandis, with sweetish red pulp. It is indicated 

 here, not without hesitation, to suggest trials of its acclima- 

 tion in regions of the temperate zone with a warm, humid, and" 

 equable temperature. The acid pulp of the pods forms the 

 medicinal Tamarind, rich in formic and butyric acid, irrespect- 

 ive of its other contents.
