JACK'S LETTERS TO WALLICH, 1819-1821. 249 



Connarus ferrugineus, Jack, was found in Penang. It 



was to it probably that Jack applied the name Connarus pani- 

 culata, Koxb., in his letters (p. 163). But after visiting Cal- 

 cutta in 1826 he used the name Connarus ferrugineus (letters 

 p. 197) and described it in the Malay. Misc. ii. No. 7, p. 37. 



Connarus semidecandrus, Jack, occurs in Penang; but 

 Jack did not detect it there. He described it from the west 

 coast of Sumatra (Malay. Misc. ii. No. 7, p. 39). It would 

 further seem to be " one of the species obtained in Singa- 

 pore, which are referred to in his letters (p. 197) : for Wal- 

 lich's Catalogue No. 8538 in part is it. 



Connarus grandis, Jack, was described from Tapanuli, 

 Sumatra, in the Malay. Misc. ii. No. 7, p. 40. 



Connarus villosus, Jack, was described from Sumatra 



in the Malay. Misc. ii. No. 7, p. 38. 



Connarus lucid us, Jack, was described from Sumatra in 



the Malay. Misc. ii. No. 7, p. 41. 



C nest is longiiolia, is a name used by Jack in his letters 

 (p. 197) for something that he got in Singapore and at 

 Tapanuli. 



C nest is emarginata, Jack, is a plant described from 

 Bencoolen in Malay. Misc. ii. No. 7, p. 43. 



Cnestis florida, Jack, is a plant from Pulau Nias and 

 Sumatra described in the Malay. Misc. ii. No. 7, p. 43. 



LEGUMINOSAE. 



Millettia atropurpurea, Benth. This common tree was 

 collected by Jack in Penang, and Wallich distributed the 

 specimens under the name of Pongamia atropurpurea (Wall. 

 Cat. No. 5910). 



Mezoneuron sumatranum, W. & A., was found by Jack 

 at Bencoolen, and is referred to under Eoxburgh's name of 

 Caesalpinia sumatrana. From the way in which Jack puts 

 a question mark after the word Caesalpinia, it seems that he 

 suspected Eoxburgh to have got the genus wrong (letter 

 p. 188). 



Cassia alata, Linn., is quite likely to have been the 

 plant to which Jack refers in his first letter from Penang 

 (p. 155). 



Saraca declinata, Miq., was described as Jonesia de- 

 dinata by Jack from Sumatra in the Malay. Misc. ii. No. 7, 

 p. 74. A reference in his letters (p. 216) indicates Bencoolen 

 as probably the locality where it was found. 



Afzelia retusa, Kurz, appears to be the Singapore plant 

 referred to in Jack's letters (p. 180).
