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



Styrax serrulatum, Boxb., was collected in Penang by 

 Jack whose specimens were distributed under Xo. 4401 of 

 Wallich's Catalogue with the name S. Porterianum. 



OLEACEAE. 



Schrebera swietenioides, Roxb., is mentioned as 

 thought to be a plant of Mansilar, towards Tapanuli, Sumatra, 

 in Jack's letters (p. 198). 



Linoceira purpurea, Yahl., is the L. odoraia which Jack 

 described in the Mala}'. Misc. ii. Xo. 7, p. 96 from Natal and 

 Pulau Mosella. 



APOCYNACEAE. 



Leuconotis anceps, Jack, was described in the Trans. 

 Linn. Soc. xiv. p. 121 from Sumatra. 



Rauwolfia sumatrana, Jack, was described in the Malay. 

 Misc. i. Xo. 5, p. 22 from Bencoolen, and finds a passing 

 mention in his letters (p. 218). 



Tabernaemontana macrocarpa, Jack, was described in 

 the Malay. Misc. ii. Xo. 7, p. 80, from the country behind 

 Bencoolen. 



Wrightia dubia, Spring., was found by Jack in Penang 

 (letters 195) and apparently again at Bencoolen (letters p. 

 218). Wallich distributed Jack's specimens from Penang 

 under the number 1643 of his Catalogue and with the name 

 Strophanti} us Jackianus. 



Marsdenia volubilis, T. Cooke (Drer/ea volubilis, 



Benth.), is mentioned in Jack's letters (p. 222) as a Sumatran 

 plant under the name of Hoya viridiflora, B. Br. 



Hoy a spp. Two Sumatran species of " Hoya " are men- 

 tioned in Jack's letters (pp. 222 and 225) as Hoya grandifiora 

 and Hoya gracilis. It cannot be that the first named is Tylo- 

 phora grandifiora B. Br., for Jack's description does not fit 

 that Australian plant, although Jack seems to have thought 

 that it did. 



LOGANIACEAE. 



Fagraea auriculata, Jack, considerably interested Jack 

 on account of the great size of its flowers : he described it in 

 Malay. Misc. ii. Xo. 7, p. 82, from Singapore and Tapanuli, 

 Sumatra : and in his letters he mentioned it several times, first- 

 ly (p. 178) its discovery, then the despatch of notes on it to 

 Wallich (p. 215) and lastly (p. 226) its occurrence at Tapa- 

 nuli. 



Fagraea carnosa, Jack, was described in the Malaya. 

 Misc. ii. Xo. 7, p. 81, from Bencoolen.
