252 JACK'S LETTEKS TO WALLICH, 1819-1821. 



Metastoma polyanthum, Blume, appears to be the 

 Sumatran part of Jack's M. mdldbatltricum . 



Melastoma obvolutum, Jack, described in Trans. Linn. 

 Soc. xiv. p. 3, is sometimes referred to M. maMbathricum ; 

 sometimes mentioned apart. Jack got it at Tapanuli, Suma- 

 tra. 



Melastoma erectum, Jack, was described in the Trans. 

 Linn. Soc. xiv. p. 5 from Tapanuli, Sumatra ; but is doubt- 

 fully distinct from the above three. 



Melastoma saguineum, Sims, was described by Jack 



in the Trans. Linn. Soc. xiv. p. 6 from Penang, under Rox- 

 burgh's name of i¥. decemfidum, 



Medinilla alpestris, Blume, was described by Jack from 

 Gunong Bengkok, Sumatra, in the Trans. Linn. Soc. xiv. p. 

 28 under the name of Melastoma alpestre. hi his letters (p. 

 234) he mentions it. 



Medinilla rubicunda, Blume. was described by Jack 

 from Singapore (Trans. Linn. Soc. xiv. p. 18) as Melastoma 

 rubicund i urn. 



Medinilla eximia, Blume, was described by Jack from 

 Gunong Bengkok, Sumatra (Trans. Linn. Soc. xiv. p. IT) as 

 Melastoma eximiuni. in his letters (p. 233) he mentions it. 



Allomorphia exigua, Blume, was described in the Trans. 

 Linn. Soc. xiv. p. 16 from Penang as Melastoma e.viguum. 



Sonerila erecta, Jack, was found in Penang (letters pp. 

 160, 162) and described in the Malay. Misc. i. No. 5. p. 7. 



Sonerila paradoxa, Xaud., was found by Jack in Penang 

 (letters p. 162) and described in the Malay. Misc. i. No. 5, p. 

 9, as Sonerila moluccana, Koxb. 



Sonerila heterophylla, Jack, was obtained at Tapanuli 

 and at other places on the west coast of Sumatra; and it was 

 described in the Malay. Misc. ii. Xo. 7, p. 16. 



Sonerila spp. Two species are named (letters p. 186) as 

 having been obtained by Baffles on his Menangkabau trip : but 

 for some reason Jack did not refer to them again in his later 

 writings, probablv because they were left with Wallich (vide p. 



232). 



Phyllagathis rotundifolia, Blume, was collected by 

 Jack in the Musi country which is behind Bencoolen and was 

 described by him under the name of Melastoma rotunclifolium 

 in Trans. Linn. Soc. xiv. p. 12. 



Marumia stellulata, Blume, was described by Jack in 

 the Trans. Linn. Soc. xiv. p. 6 from the west coast of Sumatra
