CLUSIACE^. 417 



undivided embryo of a great number of Barringtoniece is found in 

 tlie GlusiacecB, These are ordinarily placed next beside the TeiTi,- 

 strcemiacece^ with which their affinities are so close that one might 

 include in one and the same family the Guttiferce and certain Tern- 

 strosmiacece. 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 Ternstrosmiacece have not a coloured latex, and the 

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

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

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

 TernstrcemiacecB and Myrtacece, 



UsES.^ — The Glusiaeece have a yellow or greenish, more rarely 

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

 evacuant, 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 

 Gareiniece, The best comes from Garcinia Morella ^ (fig. 354, 378), 

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

 varieties alone, whether in Ceylon,* in Siam or at Singapore,^ yield 

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

 and in the arts as a yellow colour.^ G, Xantliocliajmus^ (fig. 372-375),
