Gutta-Percha of Banka. 



(Compare Nos. 4-1G of the List of Hr. Ten Brummeler. ) 



Teijsmann and Binnendijk, Nat. Tijdsehr., Pt. VI, p. 



(i) Dadauw.— Messrs. Teijsmann and Binnendijk enumer- 

 ate three sorts of Dadauw, viz., Dadauw of Seroja 1st 

 sort, Dadauw 2nd sort, and the Marawang Dadauw. The 

 first, according to them, is the product of Isonandra 

 Gutta Hk. According to information from Resident Schaap, 

 the seeds of this lastnamed plant resemble those 

 of the Sawo (Mimusops Bojeri Dc). From the dried 

 kernel and edible substance is obtained, as in the case of 

 the Sapiri (?), and the gutta itself, brown in color, is 

 worth 15 dollars per pikul. Regarding dadauw 2nd sort 

 nothing is stated ; the Marawang dadauw however yields, 

 according to Teijsmann and Binnendijk, a very bad brittle 

 gutta. The herbarium of these three varieties of dadauw 

 plants received from Resident Schaap is not in our Museum. 

 On the other hand we possess four dried plants from Banka 

 under this name, which represent perhaps four, at any rate 

 three, very different varieties. Only one of them collected by 

 Dr. Crookewit shows an agreement with the specimen 

 lately sent to us by Resident Ecoma Verstege. The speci- 

 mens of Getah dadauw in our Museum equally prove that 

 the name dadauw in Banka is a very common name and 

 that no particular species is designated thereby. Two 

 specimens in particular appear to be very bad and brittle. 

 Three other pieces on the other hand are evidently gutta 

 of superior quality. 



(ii) Njato. — Banka. — Enumerated by Teijsmann and Bin- 

 nendijk.' Regarding the gutta nothing is said. 

 Herbarium of the Public Botanic Gardens: — 

 (iii) Njato. — Banka. — Specimen in the Herbarium sent 

 by Resident Ecoma Verstege. The product, which is ob- 

 tained only in small quantity from the tree, is used solely 

 for making birdlime, while the wood serves for household 

 furniture and for making the oars of prahus. 



(iv) Njato darat (from Batoe Roesa), Njato riengoeng, 

 Njato pisang (from Djeboes), Njato teroen.— Dried speci- 

 mens of the varieties of Njato here mentioned are in 

 the Herbarium ; Njato teroen alone appears to be the 

 same as the abovementioned Njato of Resident Ecoma 

 Verstege. The name N/a.toh thus appears to have, like 

 Dadauw, a very general signification ; under this name are 

 without doubt grouped very different plants. 



(v) Kolan or Koelan. — This is probably the same as some 

 of Nos. 4,8,9,10, 12.15, 1G. of the List of Hr. Ten Brum- 

 meler. Not all however, as the description there given 

 makes it most probable that this Koelan is the product 

 of not one but two trees with differently colored bark. The 



Koelan of Banka, of which several plants are in our Herb- 

 arium and very fine specimens of gutta in the Museum, 

 for which we have to thank in great part Resident 

 Ecoma Verstege, is undoubtedly the Keratophorus Zeerii 

 mentioned above sub 1. The gutta appears to me to be 

 of good quality. The product sent to Messrs. Teijsmann 

 and Binnendijk in the year 1854 under this name was 

 certainly derived from another plant which yielded an in- 

 ferior gutta. I may here further remark that the Koelan, 

 according to the information furnished by the Resident, 

 grows as well in moist as in dry soil, that the tree pro- 

 duces a large amount of gutta, that the fruit is eaten 

 and the gutta is used for making the handles of billhooks 

 and for buckets, whilst the wood serves for household 

 furniture and the oars of prahus. 



(vi) Ketiau. — That this is the same as No. 7 of the List 

 of Hr. Ten Brummeler is rendered improbable by the 

 comparatively high value of this product, which does not 

 correspond with the low value attached to it by Messrs. 

 Teijsmann and Binnendijk. 



(vii) Katijau. — This plant, a specimen of the sap of 

 which has been sent by the Resident, is probably the 

 same. Regarding the gutta it is only stated that the tree 

 produces little and slowly. 



(viii) Djeloetoeng. — Perhaps the same as djiloetoeng No. 

 13 of the List of Hr. Ten Brummeler. The treo yields 

 gutta plentifully, but this is used only as birdlime, whilst 

 the wood serves for the making of coffins and the fruits 

 are eaten. 

 Specimens of gutta in the Museum: — 

 (ix) Getah-pertja No. 2. — A specimen of gutta collected 

 by Teijsmann. Evidently of bad quality, 

 (x) Balam tembaga. — Do. 



(xi) Getah-pertja. — Do. The gutta black and very hard. 

 (xii) Getah broehi, Getah Poedock, Getah djeloetoeng, 

 Ketiauw, Getah. Kajoe harkit, Getah mental-, Getah Kajoe 

 bitJ.it, Getah Kajoe belamjiran. — Billiton. — Among these 

 different varieties of gutta-percha there is little, judging 

 from external appearance, deserving of special remark. 

 Of none of these varieties do we possess any herbarium 

 except of Ketian, which is according to Teijsmaun the 

 Keratophorus tongipefatus T. and E. Further, I find an 

 indication to the effect that Getah djeloetoeng is the pro- 

 duct of Alstoni spec. We possess two specimens of Getah 

 djeloetoeng however of very different appearance, but both 

 without doubt of bad quality. Besides the herbarium of 

 Ketian derived from Keratophorus longipetalus I find it also 

 stated that this gutta is the product of Sideroxylon glabrescens 

 Miq. The two specimens in the Museum resemble each other 

 greatly ; it is however not possible to discover which gutta 

 is the product of the first and which of the second of the 

 plants named. Of getah poedoek also one specimen is very 

 dark in color. 



Gutta Percha of Java. 



(Compare gos. 1,2,$; 20, SO, SI, and. 32 of the. List of Hr. 

 Ten Brummeler.) 



(i) Karet andjieng. — Bantam, Samarang. — This is the plant 

 described by Hasskarl as Qhrysophyllum rhodoneurum. Re- 

 garding its product very little is yet known. 



(ii) Karet moending. — Bantam. — Kakosmanthus makro- 

 phyllus Hasskl. According to Teijsmann this tree yields a 

 dirty-white elastic gutta, which when fresh and after the 

 watery particles have been evaporated by heat can be 

 kneaded and stretched into all shapes. It is not soluble in 

 hot water, but is very smooth and soft, so that it can be 

 drawn out into the finest threads ; in this state it is some- 

 what sticky but can be worked very well with the bare 

 hands. After the lapse of time it loses this stickiness for 

 the most part, and becomes a firm mass, which is, however, 

 softer than that of Isonandra gutta. It has also not that 

 woody appearance and is not so liable to split but is much 

 more coherent. " If it is gathered in quantity, so that 

 woody and other foreign matters get mixed up with it, it 

 will probably have more agreement with the gutta of 

 Isonandra gutta, so that this u* »■ product mag be regarded as 

 a fine sort of t/ittta." ,vc. Since Teijsmann wrote this in 1S50 

 (Nat. Tijdsehrifl voor N. I., Pt. I, pp. -17i;. 177' it appears 

 that nothing further has been recorded regarding this 

 variety of gutta, which, as appears from the foregoing:, is 

 far better known as regards its botanical origin than most 

 of the other gutta-producing plants. Now however that
