of Hymenoxys. The product is a rubber-like substance, which „does 

 not, however, compare favourably with many of the lower grades of 

 rubber already on the market. W. G. Freeman. 



H[illier|, T. M., East Indian Dragon's Blood. (Kevv Bulletin. 

 190b. p. 197—199.) 

 The resin known as East Indian Dragons Blood is obtained 

 from the Shells of the fruits of various species of Daemonorops, ciim- 

 bing rattan pahns. In the Malay Peninsula the product is yielded 

 by D. didymophyllus, D. micranthus, and D. propinqiius. In Su- 

 matra by D. Draco., and in Borneo by D. Draconcellus. The 

 ast four of the above species are the more important. 



„Drop Dragons Blood" is stated to be obtained froni species 

 of Dracaena. W. G. Freeman. 



H[illier], T. M., Ogea Gum. ("Kew Bulletin. 1906. p. 199—200.) 



Under the name „Ogea Gum" various resins are known from 

 Lagos, the Gold Coast and Southern Nigeria. The source 

 of specimens from the Yoruba country, Lagos, has been identi- 

 fied as Damella thiirifera, known as the Frankincense tree, and also 

 as Bungo or Bungbo in Sierra Leone. Another specimen of 

 Ogea gum from Lagos proves to be obtained from a species of 

 Cyanothyrsiis. It appears probable that various species of this genus 

 and the Damella yield the products passing under the collective 

 name of Ogea Gum, but further investigations are needed.

Evidence is brought to show that some, if not the greater part, 

 of the Persian gum of commerce is derived from Amygdalus leio- 

 carpa Boiss. W. G. Freeman.
