Castilloa elastica, the Panama Rubber, was introduced to the 

 Malay Peninsula by the Botanic Gardens of Singapore, in 1876. 

 The climate is, however, unsuited for this plant, and it usually falls 

 a victim to the attacks of the beetle (Epepseotes luscus). 



Manihot Glaziovii, Ceara Rubber, was introduced also by the 

 Singapore Botanic Gardens, and plants were planted in Perak by 

 Mr. Murton, in 1876. 



Mr. MURTON did not believe in the suitability of the plant for 

 this climate, as prolonged wet destroyed it, and he pointed this out 

 in his Annual Report in 1878. In spite of this, a mania arose for 

 planting it some years later, with the expected result of its perish- 

 ing. Good trees, however, persist in many parts of the Peninsula and 

 in Borneo, but no one now would attempt it on a large scale. One 

 big tree in the Singapore Botanic Gardens fruits constantly and its 

 seeds have been sent to many parts of the Peninsula and to other 

 parts of the Peninsula and to other parts of the world and the large 

 tree at Kuala Kangsa flourish still or did till quite lately but pro- 

 duces too little latex. 



H ancornia speciosa, the " Mangabeira" Rubber of Pernambuco 

 was introduced by the Singapore Gardens in 1882. It perished 

 however, and attempts to procure it again have failed. It is appa- 

 rently a very troublesome plant, both seeds and plants travelling 

 badly. It is an inferior Rubber and is suited only for dry regions. 

 I have seen it on the sandy heaths of Pernambuco, where it grows 

 as a small tree like a birch. 



Mascarenhaisia elastica was introduced by the Botanic Gardens, 

 being received from Kew in 1898. It grows steadily, but not very 

 fast except at first. It flowered early and fruited this year. 



Kickxia (Funtumia) africana was introduced from Kew, by the 

 Singapore Gardens in 1897, an( ^ Kickxia elastica^ the following year. 

 The latter has not proved much of a success in any part of the Pen- 

 insula, being much attacked by the caterpillar of Caprinia conchy- 

 lalis. 



Landolphias. — A large number of the Rubber vines of Africa have 

 been introduced by the Botanic Gardens, Singapore, chiefly received 

 from Kew and the better class ones distributed to various parts of 

 the Peninsula, Borneo, etc.

Willoughbeias, etc., the Malayan Rubber vines, were brought into 

 cultivation by MuRTON, Cantley and myself and widely distributed 

 to all, who would try them; About a dozen kinds were cultivated
