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



Jack's specimens Wallich founded Congea Jackiana, a name to 

 be found in his Catalogue Xo. 1735. 



Avicennia sp. An Avicennia is mentioned under the 

 name of A. resinifem, in Jack's letters (p. 220) as occurring at 

 Bencoolen ; and mentioned again under his description of 

 Pijrrliantlius. 



LABIATAE. 



Ocitnum Basilicum, Linn., was recorded as collected by 

 Jack at Penang in Wallich's Plantae Asiatieae Eariores ii. p. 

 13, and occurs in Wallich's Catalogue as No. 2713. Sir David 

 Prain's remarks (Journ. Asiatic Soc. Bengal, lxxiv. p. 7<>2) 

 may be referred to as showing that Wallich's 2713, is some- 

 thing unusual. 



NEPENTHACEAE. 



Nepenthes ampul/aria, Jack, was brought to Jack from 

 Singapore by Parties (letters p. K>3). and then was found b) 

 Jack himself in the same place (letters p. ITS) and also at 

 Ehio. Jack put a description into print but did not publish 

 it : it would have formed part of his third paper in the Malayan 

 Miscellanies, had he not withdrawn it. Sir William Hooker 

 in 1835 reprinted and published this description in the Com- 

 panion to the Botanical Magazine, i. p. 211. 



Nepenthes Rafflesiana, Jack, was likewise collected in 

 Singapore first by Eaffles (letters p. 103), and then again by 

 Jack (letters p. 178). Jack's description was similarly put 

 into print but withdrawn from his third paper in the Malayan 

 Miscellanies : and similarly also published by Sir William 

 Hooker in 1835 in the Companion to the Botanical Magazine, 

 i. p. 2 70. 



Nepenthes phyll amphora, Willd.. was obtained by 

 Jack, in Bencoolen, and other parts of western Sumatra : he 

 mentions finding it at Bencoolen in his letters (p. 186). lie 

 described it in print for the third paper of his Descriptions of 

 Malayan Plants and the reprinting and publishing were done 

 in 1835 by Sir William Hooker in the Companion to the 

 Botanical Magazine i. p. 271. 



Nepenthes gracilis, Korth. is assuredly the A. distilla- 



toria of Jack, described very briefly along with the last from 

 Singapore and Malacca. It is possible that Eaffles first got it 

 in Singapore (letters p. 163). Macfarlane, in Das Prlanzen- 

 reich, iv. Xo. Ill, p. 59, quotes a specimen collected by Jack.. 



CYTINACEAE. 



Rafflesia Arnoldi, E. Br., was found first by Eaffles and 

 Arnold, before Jack joined the service at Bencoolen. Jack, 

 later found it to be by no means rare in the country behind
