T. (rEXTAPiEKA) rriiiFOLiA, Prcsl. Tcgu and Tenasserim. 



Len.

 J-f inch across.

 coloured. 



* * 2\ltfs 4- or ^-cornered, all the angles expanded into equal wings. 



T. ALATA, Eoth. All over Pegu and Martaban. 



Pentaptera tomentosa, Eoxb. 

 T. elliptica, Willd. 



Htouk-kyan. 



All parts more or less greyish tomentose. Leaves strongly net-veined beneath, 

 the petiole short, fimiished with 2 stalked turbinate glands. 



T. CRENULAiA, Kotli. Arakau, Pegu Range, and Tenasserim up to 2000 feet. 



Fentaptera glabra, Eosb. 

 T. Arjana, Bedd. 



Htouk-kyan. 



All parts glabrous. Leaves not prominently net-veined beneath, the petiole 

 short, ■with 2 stalked turbinate glands. Spikes panicled, like the calyxes, puberulous 

 or almost tomentose. 



var. macrocarpa, Wall. 



As preceding, but the panicled spikes and outside of calyx quite glalirous. 



Several Terminalias afford splendid timber. T. crenulata, the Htoiik-yan (or Arjun 

 in India), is an admirable brown -wood, weighing 70 lbs., and of the largest scantling. 

 Kurz (following Brandis) says 58 lbs., which I am conficlent is an error. T. tomentella, 

 or Mpun-gfih, is an equally fine wood, vei-y similar, and weighing 64 lbs. It is procurable 

 of the largest scantling ; and the yellowish sap wood is in large trees scarcely inferior 

 to the dark brown heartwood. T. pijrifolia or Len yields a poor timber, but is a 

 highly oi-namental and umbrageous tree, deserving of planting along roads and as an 

 ornamental tree round houses. 



Myrobalans are the dried unripe fruit of different species of Terminalia, and are 

 classed as Chobulic {T. chehula), Citrine {T. eitrina), Belleric {T. lelleriea), and Emblie 

 {Embliea officinalis). Good myrobalans yield 40 per cent, of tannic acid, but if 

 allowed to' ripen before being gathered are very deficient in tannin. Owing to the 

 expense of grinding the myrobalans in England, Mr. Christy' remarks : " If a properlj' 

 prepared extract of these different varieties could be obtained in India, there would 

 be a very large demand for it by the tanners of England." To prepare the extract'' 

 the raw material, either myrobalans, barks or other products, must be ground or 

 pulverized and macerated in sufficient cold water just to cover it for 24 hours. 

 The first solution should now be pumped off and used with a fresh charge, and 

 this may be repeated four times. The liquid fully charged with tannin may now be 

 concentrated. This is recommended to be done in copper or earthen vessels, iron 

 being wholly inadmissible, but the concentration could equally well be carried on 

 in India (save in the rains) in open shallow brick pans which, if asphalted, would 

 form most efficient evaporating pans by the sun's heat alone. If artificial heat is 

 used, it must be carefully regulated and the specific gi-avity recommended for such
