220 NATURAL HIS TOBY OF PLANTS. 



Ham., alatus Roxb., incomes Roxb., costatus, G^ertn. The Dammar 

 selan of Malaya is an analogous resinous product extracted from the 

 Vafica Selanica Wight & Arn. In Borneo the concrete juices 

 of V. Balg/ngeran Korth. (Njuting Mabambong), V. Savgal Korth. 

 and V. Bassak, Bl. {Njiito) are also used. V. robusta Wight 

 & Arn., of India exudes a kind of incense which is burnt in the 

 temples under the name of Red or Doona. Shorea Twmbugaia 

 produces an analogous matter used to coat ships. S. Jala, Buch., 

 gives a sort of gum-lac. A kind of balm is still burnt at their 

 religious feasts extracted from Valeria lanceolata, Roxb. In short all 

 these trees have a juice possessing very homogeneous qualities, more 

 or less solidifiable, combustible, often odoriferous, resinous, balsamic, 

 furnishing oils, varnishes, tar, and sometimes camphorous substances. 

 This is to a certain point a distinctive character to add to those of 

 the JDipterocarpce. Their wood is hard, beautiful, fit for building 

 purposes. In Java and Borneo are especially employed Diptero- 

 carpus gracilis Bl., marginatus Korth., littoralis Bl., trinervis Bl., 

 rehisusl$L., Spanoghei Bl. ; in India that of Shorea robusta (vulg. Saul), 

 several Vaticas and Valerias : these are trees, like the Drgobalanqps, 

 often attaining a height of a hundred feet. The authors of the Florce 

 Sencgambice Tentamen say of the Lophira alafa (figs. 217-221) that 

 " the beauty of this tree, as to its foliage and flowers, ought to draw 

 the attention of horticulturists ; and would be a valuable acquisition 

 to our greenhouses, and to the inter-tropical colonies of Asia and 

 America."
