JACK'S LETTEES TO WALLICH, 1819-1821. 251 



occurring in the Malayan Peninsula and Sumatra. In his 

 letters he writes of rinding it in Penang (p. 165) and on the 

 Silebar river, Sumatra (p. 205). 



Calycopteris floribunda, Lamk., is mentioned as a 

 Penang plant in his letters (p. 184). 



Quisqualis densiflora, Wall., was described by Jack 

 under the name of Splialanthus confertus in the Malay. Misc. 

 ii. Xo. 7, p. 55, no locality being given. 



MYRTACEAE. 



Leptospermum sp. is the identification given of Jack's 

 Glapliyria sericea from Pulau Pinang on the west coast of 

 Sumatra (not the British Penang). Jack described it in 

 Trans. Linn. Soc, xiv. p. 129. By an oversight it was in- 

 cluded in the Flora of British India. 



Leptospermum sp. would be the 'identification of his 

 Glaphyria nitida from G'unong Bengkok, described in the same 

 place p. 128 and in the Malay. Misc. ii. No. 7, p. 6. 



Melaleuca leucadendron, Linn., is named by Jack in 

 his letters (p. 160) as obtained in Penang; he uses Eoxburgh's 

 name M. Cajuputi. 



Rhodamia trinervia, Blume. It appears that Jack had 

 obtained from Sumatra this plant and also its variety specfa- 

 bilis. He refers to them in his letters (p. 222) and in the 

 Malay. Misc. ii. Xo. 7, p. 48. 



Eugenia Jambos, Linn., was collected by Jack in 

 Penang; and W allien distributed the specimens as Xo. 3615 

 of his Catalogue. 



Eugenia caryophyltata, Thunbg., was mentioned by 

 Jack as cultivated in Penang (letters p. 152). 



Barring tonia speciosa, Forst., is mentioned in Jack's 

 letters (p. 174) as a plant of Acheen. 



Barringtonia racemosa, Eoxb., is mentioned in Jack's 

 letters p. 175) as a plant of Penang. 



Barringtonia macrostachya, Kurz, was described by 

 Jack (Malay. Misc. i. Xo. 1, p. 47) as Careya macrostaclii/a, 

 from Penang. 



MELASTOMACEAE. 



Melastoma malabathricum, Linn., attracted Jack's at- 

 tention in Penang during his first days there (letters p. 152) ; 

 and afterwards he paid great attention to the order to which it 

 belongs. In describing it in the Trans. Linn. Soc. xiv, p. 4, 

 he gives the localities as " Sumatra and the Malay islands." 

 Under M. malabathricum he included the very closely allied 

 M. polyanthum, and appears to have described the latter rather 

 than M. malabatliricum under the name of " malabathricum."
