JACK'S LETTEES TO WALLICH, 1819-1821. 259 



Fagraea fragrans, Eoxb., was found in an old garden at 

 Penang, and on the Kedah shore (letters pp. 178 and 215). 



Fagraea obovata, Wall., was found at Singapore (letters 

 p. 195). 



Fagraea racemosa, Jack, must have been found on the 

 Sumatran coast (letters p. 215) already when he got it on 

 Pulau Xias (letters p. 226). It was described in Carey's and 

 Wallich's revision of Eoxburgh's Flora Indica, ii. p. 35. As 

 Jack states in the Malay. Misc. ii. Xo. 7, that his total of 

 species of Fagraea was five, the other references to the genus 

 in his letters must refer to some of the above. 



CONVOLVULACEAE. 



Neuropeltis racemosa, Wall., is mentioned as a Penang 

 plant in Jack's letters (pp. 166 and 216). 



BORAGINACEAE. 



Cordia subcordata, Lamk., is mentioned as a Singapore 

 plant in Jack's letters (p. 179). 



SOLANACEAE. 



Datura arborea, Linn., a South American plant is men- 

 tioned in Jack's letters as at Bencoolen, where doubtless it was 

 in cultivation (letters p. 217). 



GESNERACEAE. 



Aeschynanthus grandiflora, Spreng. Jack (letters p. 

 228) says that he obtained Tncarvillea parasitica, Eoxb. at 

 Bencoolen: but in his published writings he does not refer to 

 it; and consequently it may be assumed that he had realised 

 some difference between his plant and Eoxburgh's. 



Aeschynanthus volubilis, Jack, was described as a 

 plant of Bencoolen in the Trans. Linn. Soc. xiv. p. -12. Per- 

 haps it is the plant mentioned in his letters (p. 237). 



Aeschynanthus radicans, Jack, was described as a 

 plant found in the interior of Sumatra, Trans. Linn. Soc. 

 xiv. p. -13. 



Didymocarpus reptans, Jack, was described from 

 Penang in the Malay. Misc. i. Xo. 5, p. 3, and in Trans. Linn. 

 Soc. xiv. p. 35. It may be the plant referred to in letters 

 (p. 162). In the Trans. Linn. Soc. xiv. p. 35 the locality 

 given is " with the proceeding," which is D. racemosa 

 from Tapanuli; but this Tapanuli plant is an intercalation, 

 and the " proceeding " intended is D. crinita, which is a 

 Penang plant.
