and engineering work. All the species do not yield gutta-percha, as 

 Seen in the following summary grouped under-genera: 



I. Chrysophylluni: one species C. Roxhiirghii, "Starapple". Not 

 gutta producer. 



IL Sarcosperma: one species 5. panicidatiim. Not gutta producer. 



III. Sideroxylon: five species. None recorded as yielding gutta percha. 



IV . Isonandya: two species. 



V. Payena: nine species. Some yield gutta percha of inferior 

 quality. P. Maingayi, closely resembles in foliage the valuable Pala- 

 giuni Gutta. It yields a latex which however never hardens although 

 when freshly drawn it looks like good gutta. P. Leerii "White Gutta" 

 or "Getah sundek", of considerable importance as a gutta yielding 

 plant. P. Havilandi "Sinarum". Gutta as good as preceeding. P.lucida 

 most common species of this genus in the Peninsula, but does not 

 yield gutta. P. dasyphylla some accounts say it yields a poor gutta 

 used for adulteration purposes. although others doubt its possessing 

 even this value. P. sessilis, P. ohtusifolia , and P. selangorica. These 

 three species are but little known, and so far have not been reported 

 as yielding gutta percha. 



VI. Bassia: Seventeen species. None apparently yield goot gutta, 

 although B. nialaccensis , B. cuvtisii, and B. ynotleyana yield poor 

 guttas chiefly used for mixing with other kinds. 



VII. Palagimn: twelve species. P. gutta is the most important 

 gutta percha tree. It is locally known as "Gutta Taban" on "Taban 

 Merah", merah meaning red. P. gutta var. ohlongifoliuin yields the 

 important "Getah Tabah Sutra". Closely allied is P. oxleyanuni Pierre 

 {Dichopsis pustulata Hemsl.) giving an inferior gutta. It is called 

 "Taban Sutra" or "Taban Putih" and according to Wray "Taban 

 Chaia". P. obovaticni yield a gutta as to the quality of which observers 

 differ. P. Maiugayi "Getah Taban Simpor" P. Clarkeanuni, P.xantho- 

 chyvnimi, P. banca^ium, all appear to yield small quantities of' 

 inferior gutta. 



VIII. Mimusops: two species. M. Elengi, and M. Kauki both im- 

 portant trees but not gutta producers. 



For purposes of cultivation as gutta producers attention should be 

 confined to Palagiunt Gutta and its variety ohlongifoliuin which are 

 the most important, and P. oxleyanuni , P. ohovatum , and Payena Leerii. 



An account is given of the Steps taken to prevent the destruction 

 of the gutta forests and to provide for a permanent supply when 

 the rescues and plantations after some years can begin once more 

 to produce a regulär yield. W. G. Freeman.
