Tanacetum vulgare, Linne. 



The Tansy. North and Middle Europe, North Asia, North-. 

 Western America. A perennial herb of well-known medicinal 

 value, which mainly depends on its volatile oil. 



Taraxacum officinale, Weber. 



Dispersed over most of the temperate and cold parts of the globe, 

 but apparently not a native of South-East Australia. This well- 

 known plant is mentioned, as 'it can be brought under regular culti- 

 vation to obtain the medicinal extract from its roots. It is also 

 considered wholesome to grazing-animals. The young leaves 

 furnish a medicinal salad. It is also an important honey plant and 

 early in the season. 



Tarchonanthus camphoratus, Linne. 



South Africa. This bush deserves attention, being of medicinal 

 value. As an odorous garden plant it is also very acceptable. 



Taxodium distchum, Richard.* 



Virginian Swamp or Bald-Cypress. In Swampy places of Eastern 

 North America, extending from 38 to at least 17 north latitude. 

 Thought to attain occasionally an age of 2,000 years. A valuable 

 tree, 100 feet higher more, with astern circumference of sometimes 40 

 feet above the conical base ; of rapid growth, with deciduous foliage, 

 like that of the Larch and Ginkgo. Important as anti-malarian 

 for wet fever-regions. It is found fossil in the miocene formation 

 of many parts of Europe. . The wood is fine-grained, hard, strong, 

 light, elastic and very durable, splits well, and thus much used for 

 shingles, rails, cabinet work and planks ; it is almost indestructible 

 in water. The tree requires a rich soil, a well-sheltered site, with 

 much moisture and good drainage (Lawson). It yields an essential 

 oil and a superior kind of turpentine. Useful for avenues on 

 swampy margins of lakes or river banks. Porch er says, " This 

 tree, lifting its giant form above the others, gives a striking 

 feature to many of the swamps of Carolina and Georgia ; they 

 seem like watch-towers for the feathered race." 



Taxodium mucronatum, Teno. 



The famed Montezuma Cypress of Mexico, 120 feet high, with a 

 trunk 44 feet in circumference ; it forms extensive forests between 

 Chapultepec and Tescuco.
