60 NOTES ON OtfTTA PERCHA. 



As regards Gutta jelutong, Mr. Treacher's description of 

 the Bornean trees entirely coincides with my knowledge of 

 it, and from an examination of imperfectly developed flow- 

 ers Dr. Beccari arrived at the same conclusion. 



The timber of the jelutong is sometimes used in Singa- 

 pore for making the Malay trompah or wooden sandals. 



Mr. Treacher in one place describes the fruit as " being 

 " a black pod like that of a bean ;" but a reference at the 

 foot of the page describes it as "2 J inches long, pear shaped, 

 " coming to a sharp point and attached by large end" — two 

 descriptions which appear to me diametrically opposed. 



I have not seen the fruit of the Alyocia, but it thus des- 

 cribed by the authors of the " Genera Plantarum" " Drupse 

 " v. baccse 2 v. abortu solitaria?, ovoidese v. oblongse'l — 

 " spermse v. moniliferso, articulis 2 rarius 3 — 4 oblongis 1 — 

 " spermes." 



I add also the general description of the genus for compa- 

 rison, from the same source : — 



u Frutices ssepius glabri. Folia 8-4-natim verticillata v. 

 "rarius opposita, coriacea, nitida, pennivenia venis lamen 

 " parum prominulis.''' Flores parvuli, gemini v. C3 T mosi, 

 cymis capitellatis fasciculatis v. breviter spicato-paniculatis 

 . axillaribus v. in axillis foliorum terminalium pseudo — 

 terminalibus. 



A specimen of what appears by Mr. Treachers descrip- 

 tion to be a Serapit has been sent from the jungle here to 

 Kew and Professor Oliver has identified it as a Chilocarpus. 

 Professor Dyer considers the Perak " Gutta Singgarip" 

 which is evidently one of the Bornean Manungans to be 

 identical with Wallich's Willughbeia martabanica. Later on, 

 referring to some specimens collected in Singapore he writes: — 



" The Gutta Singgarip plant that you have met with 

 " near the Boianic Garden is an interesting discovery. It is 

 " not, I think, the same as the Perak plant, though very 

 " close to it, — on the other hand it may be the same as one 

 " of Mr. Burbidge's Bornean species." 



Hundreds of young plants of at least five of these rubber- 

 producing climbers are now established in the Botanic gar-
