JACK'S LETTERS TO WALLICH, 1819-1821. 253 



Marumia nemorcsa, was collected by Jack in Sumatra 

 and on Pulau Xias, and was described under the name of 

 Melastoma nemorosum in Trans. Linn. Soc. xiv. p. 8. 



Dissochaeta bracteata, Blume, was described by Jack 

 from Penang in the Trans. Linn. Soc. xiv. p. 9 as Melastoma 

 bracteatum. 



Dissochaeta pallida, Blume, was obtained first in 

 Penang (letter p. 163) but was described after lie had got it 

 elsewbere (Trans. Linn. Soc. xiv. p. 12), under the name of 

 Melastoma pallidum. Wallich distributed specimens under 

 Xo. 4049 collected by Jack in Penang. 



Dissochaeta celebica, Blume, is very probably Jack's 

 Melastoma fallax from Sumatra (Trans. Linn. Soc. xiv. p. 13). 



Dissochaeta gracilis, Blume, is Jack's Melastoma 

 gracile from Sumatra (Trans. Linn. Soc. xiv. p. 14). 



Anptectrum divaricatum, Triana, is Jack's Melastoma 

 glauca from Penang (Trans. Linn. Soc. xiv. p. 14). In his 

 letters (p. 234) he writes of it. 



Pogonanthera pulverulenta, Blume, is Jack's Melas- 

 toma rubicundum and pulverulentum from Singapore and 

 Sumatra, as well as the islands off the west coast (Trans. Linn. 

 Soc. xiv. p. 19). 



Anplectrum viminale, Triana, is Jack's Melastoma 

 viminale from Sumatra (Trans. Linn. Soc. xiv. p. 16). 



Pternandra coerulescens, Jack, was found in Penang 

 and described in the Malay. Misc. ii. Xo. 7, p. 61. 



Pternandra capitellata, Jack, was named and very 

 briefly diagnosed in the addenda prefixed to Malay. Misc. ii. 

 Xo. 7 (p. iii). He had found it at Moco-moco, Sumatra. In 

 the Flora of British India ii. p. 537 it is said to have been 

 found b'y Jack in Penang: but the authority for this is un- 

 known to me. However it is a common species of Penang, 

 which Sir George King regarded as but a variety of the last. 



Kihessa simplex, Korth., appeared as Pternandra eclii- 

 nata in Wallich's Catalogue Xo. 4078, and is named in the 

 Malay. Misc. ii. Xo. 7, p. iii, the locality being recorded as 

 Kataun. Griffith on p. 310 of the Calcutta Journal of Xatural 

 History, iv. says Kataun in Malacca; but it is without doubt 

 Pasar Katahun, a days journey northward up the coast from 

 Bencoolen. 



Memecylon caeruleum, Jack, was found in Penang 

 (letters p. 184) and described in the Malav. Misc. i. Xo. 5, p. 

 26. 



Memecylon paniculatum, Jack, was described from the 

 island of Pulau Bintangor and the Sumatran coast at Tapanuli 

 in the Malay. Misc. ii. Xo. 7, p. 62. 



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