CASE Observe Room or Maigyeb, a blue dye (indigo) 



88. produced by Strohilanthes flaccidifolius^ Nees, a shrub of 

 North and East Bengal, extending from Assam into South 

 China, where it is thought finer than the blue dye 

 obtained from any other plant. 



Note also stems of the Kariyat (Andrographis 

 paniculata^ Nees), a plant common in dry, shady places in 

 nearly all parts of India and Ceylon, and introduced into 

 the Mauritius and West Indian Islands. It has bitter, 

 tonic and stomachic properties similar to Chiretta and 

 Gentian, with the former of which it has been confounded 

 in Indian medicine. 



Observe flowers, leaves, and wood of Adhatoda Vasica^ 

 Nees, a small shrub of India, Burma, and Malaj'a. The 

 leaves yield a yellow dye, but their chief use is as a 

 dressing for rice-fields, as they seem to have the power of 

 killing aquatic weeds. An infusion of them is also used 

 as an insecticide. The wood is employed for charcoal for 

 making gunpowder. 



Note specimens of root of Tong-PANG-Chong {Rhina- 

 canthus commu7iis, Nees), used in India and China in the 

 treatment of ringworm and other cutaneous diseases. The 

 plant is universally known in Lower India as N AGAMULLIE. 



Note a few products of a minor character belonging to 

 the small order Myoporineae, an order of shrubs and 

 small trees, chiefly Australian. 



Vervain Order ( Verhenaceae), A large Order widely 



distributed over the New and Old Worlds, but most 



abundant within the tropics ; some of the species furnish 



valuable timbers. 



CASE Observe wood of Petitia domingensiSy Jacq., from the 



89. West Indies where it is one of the woods known as 

 FiDDLEWOOD, the name being a corruption of Bois-fidele, 



No. 396. Teak (Tectona grandis, L.). A deciduous 

 tree attaining a height of 120 to 150 feet, with a girth of 

 20 to 25 feet. Native of India, Burma, and the Malay 

 Archipelago. This is the chief export timber of India 

 and Burma, and it is also exported from Java, where there 

 exist large plantations of great value. Once seasoned, 

 Teak-wood does not split, warp, or alter its shape ; its 

 principal value is its great durability. It is one of the
