JACK'S LETTEKS TO WALLICH, 1819-1821. 255 



Argostemtna humile, Benn., was obtained by Jack in 

 Penang and sent to Wallich. Wallieh described the plant in 

 Bennett's Plantae Javanicae Kariores p. 94, and distributed 

 Jack's specimens under his number 8391. 



Mussaenda glabra, Yahl, is probably the Penang plant 

 which Jack calls M. frondosa (letters p. 155). 



Lucinaea Morinda, DC, is Jack's Morinda polyspermia 

 (Malay. Misc. i. Xo. 5, p. 1-4) from Singapore. He mentions 

 it in his letters (p. 194). 



Timonius Koenigii, Blume, is the Helospora favescens 

 of Jack described in the Trans. Linn. Soc. xiv. p. 127, from 

 Sumatra. 



Urophyllum glabrum, Wall., is a name which Wallich 

 gave to a plant described in MS. by Jack for him, Jack had 

 proposed to call it Patisna glabra or Wallicliia glabra (letters 

 pp. 196 and 218), and Wallich published the description in 

 Carey's and his revision of Roxburgh's Flora Indica, ii. p. 186 

 altering the generic name. Urophyllum glabrum was obtained 

 by Jack in Penang, and found again later at Tapanuli, 

 Sumatra. 



Urophyllum villosum, Wall., was found by Jack in 

 Penang and described along with the last. It is mentioned 

 incidentally in Jack's letters (p. 196). 



Lecananthus erubescens, Jack, was described in the 

 Malay. Misc. ii. Xo. 7, p. S3 from the country behind Ben- 

 coolen. 



Randia amsophylla, Hook, f ., was described by Jack in 

 Carey and Wallich's revision of Roxburgh's Flora Indica ii. 

 p. 461 from Penang as Gardenia anisopliylla. In Wallich's 

 Catalogue it appears as Gardenia 1 ? anisopliylla Xo. 8399. It 

 is a common tree in Penang. It is mentioned in his letters 

 (p. 220). 



Scyphyphora hydrophyllacea, Gaertm. was referred to 

 in one of Jack's letters (p. 219) as found in Singapore; and in 

 the Malay. Misc. i. Xo. 5, p. 12 he described it as Epithinia 

 malayana. 



Guettarda speciosa, Linn., is mentioned in Jack's letters 

 (p. 175) as a Penang plant. 



Ixora petidula, Jack, was described in the Malay. Misc. 



i. Xo. 5, p. 11 from Penang; and it is probably one of the 

 species referred to in his letters (p. 171). See also p. 228.

 ii. Xo. 7, p. 82 from the west coast of Sumatra. It is men-
