CLUSIACEM. '117 



undivided embryo of a great number of Barringtoniece is found in 

 the Clusiaceœ. These are ordinarily placed next beside the Tem- 

 strœmiaceœ, with which their affinities are so close that one might 

 include in one and the same family the Guttiferœ and certain Tem- 

 strœmiaceœ. The latter are distinguished by their alternate leaves, 

 or, in the exceptional types with opposite leaves, by their flowers in 

 clusters, with alternate pedicels, ordinarily hermaphrodite and very 

 rarely tetramerous, so that their sepals and petals are not decussate. 

 Further, the Temstrœmiaceœ have not a coloured latex, and the 

 embryo, often curved, has distinct and independent cotyledons, when 

 even they are not largely developed. Finally, the Clusiaceœ, scarcely 

 separable from the St. John's Worts, appear equally allied to the 

 Temstrœmiaceœ and Myrtacece. 



Uses. 1 — The Clusiaceœ have a yellow or greenish, more rarely 

 ■whitish latex, which contains an acrid resinous matter, often possessing 

 évacuant, sometimes stimulant and tonic properties. The most 

 celebrated, as well as the most active of these substances, is gum- 

 gutta, the production of which has been attributed to several 

 Garcinieœ. The best comes from Oarcinia Morella 2 (fig. 354, 378), 

 and it seems clear, from the most recent researches, 3 that its different 

 varieties alone, whether in Ceylon, 4 in Siam or at Singapore, 5 yield 

 the good gum-gutta used in medicine as a drastic and hydragogue, 

 and in the arts as a yellow colour." G. Xanthocliymus 1 (fig. 372-375),
