Ternstrcemiacece are next considered. Hurt/a Celebica, Rwdt. MSS., 

 is a new species ; Gordonia Wallichii^ De Cand,, is transferred to Schima, 

 as is the 8. Wallichii of Korthals. 



Sauraujea are considered as a distinct family from Ternstrosmiacece. 

 No less than ninety-seven species are characterized ; but these include 

 the discoveries of others besides Reinwardt. 



Sapotacece. — This family is of peculiar interest, as including the now 

 celebrated though only recently discovered Gutta Percha (" rectius verb 

 Getah-Pertja "), and our excellent friend gives a valuable catalogue of 

 the Sapotacece, (with characters and remarks,) of the genera and species 

 of the Malay Archipelago, known to yield substances analagous to 

 Gutta Percha ; and he strongly urges inquiry to be made as to the rela- 

 tive value of the respective products. The species are as follows : 



I. Chry sophyllam lanceolatum, De Cand. 2. C. rhodoneurum^ Hasskl. 

 3. Sideroxylon nitidum, Bl. 4. S. attenuatum, De Cand. 5. S.? chry-

 and with the same points of distinction from the Singapore plant, but 

 unfortunately without flowers. 8. /". puberula, Miq. 9. I. dasyphylla,

Myrtacea. — Under Melaleuca Cajeputi, the question is considered 

 whether the green colour of the oil is natural to it, or due to the copper 

 vessel in which it has been distilled ; and this seems to be set at rest 

 by the experiment of Reinwardt, who distilled the leaves in water in a 

 copper vessel lined with tin, when an oil was obtained, " fere limpidum, 

 subflavescens, sed non viride." Interesting information is given re- 

 specting the Clove (Gary op hy Hits aromatica, Linn.), and allusion is made 

 to the many errors of authors regarding its history, especially of Mr. 

 Crawford in his work on the Indian Archipelago, a subject that will be 

 more fully treated on in the * Travels of Reinwardt/ about to appear. 

 Barringtonia is represented by four species. The fasciculus closes with 

 Dilleniace/P, but affording nothing new. The plates, three in number,
