JACK'S LETTEES TO WALLICH, 1819-1821. 247 



Aglaia odorata, Lour., is a common tree of cultivation 

 in Malaya, as Jack records (Malay. Misc. i. Xo. 5, p. 32). 



Aglaia sp. is the Lansium montanum of Jack found in 

 the forests near Bencoolen (Trans. Linn. Soc, xiv. p. 117). 

 Eumpf had used the combination; and Jack believed that he 

 had got Eumpfs plant. The name Lansium montanum is 

 sometimes referred to Steudel. 



Lansium domesticum, Jack, is the cultivated Langsat 

 which Jack described in the Trans. Linn. Soc. xiv. p. 115. 

 He defined a variety aqueum (L. aqueum), a superior race. 

 In his letters (p. 158) he names it as the " Dookoo." 



CELASTRACEAE. 



Paracelastrus bivalvis, Miq. (Microtropis bivalvis, 

 Wall.) , was obtained by Jack in Penang and described as 

 Celastrus bivalvis (Malay. Misc. i. Xo. 5, p. 19). He men- 

 tions it in his letters (pp. 165 and 218), first as related to 

 Celastrus and then as Celastrus bivalvis. 



Celastrus pauciflora, Wall., is the Pittosporea? serru- 

 lata of Jack from Penang which Griffith named Pittosporum? 

 serrulatum in the Calcutta Journal of Natural History, iv., 

 1844, p. 195. 



Celastrus lucida, Wall., is a plant, not a Celastrus, col- 

 lected by Jack in Penans: and distributed under this name by 

 WaUich (Cat. Xo. 4318). 



Hippocratea, sp. near H. obtusifolia, Boxb. is mentioned 

 in Jack's letters (p. 221) as having been found in Pulau Xias. 



Salacia sp. Jack found on Pulau Xias a Salacia which 

 in his letters is called Jolinia sumatrana, and would be one 

 of the two species referred to, without name, in the Malay. 

 Misc. ii. Xo. T, p. 92. 



Salacia sp. Jack had sent to Wallich a species of Salacia 

 under the name of Hypsagyne (letters 219 and 221) which 

 was obtained at Tapanuli earlier than the Salacia just named. 

 It may have been the second Salacia mentioned in the Malay. 

 Misc. ii. Xo. 7, p. 92. Of these two species the one, he wrote, 

 agrees very well both with 8. cliinensis and with Jolinia sola- 

 cioides (which is Salacia Boxburgliii, Wall.) ; and the other is 

 nearly related to Jolinia coromandeliana, Eoxb. (which is 

 Salacia yrinoidcs, DC.) 



AMPELIDACEAE. 



Vitis raeemifera, Jack, was described from Sumatra in 

 the Malay. Misc. ii. Xo. 7, p. 94. 



Vitis angustifolia, Wall, is recorded by Jack from Ben- 

 coolen (letters p. 208) under EoxburgrTs name of Cissus 

 angustifolia. 



R. A. Soc. No. 73, 1916.
