MYRTACEvE. XIV. EUCALYPTUS. 



SUBTRIBE II. EUI.EPTOSFE'RME;E (from cu, well, and lepto- 

 spermum ; this subtribe contains plants agreeing with Leptospcr- 

 mum in the free stamens). D.C. prod. 3. p. 216. Stamens free. 

 XIV. EUCALY'PTUS (from , cu, well, and KaXvirro, 

 kalyplo, to cover, as with a lid ; in reference to the limb of the 

 calyx covering the flower before expansion, and afterwards fall- 

 ing off in one piece, in the shape of a lid or cover (f. 118. 6.). 

 Lher. sert. angl. 18. D. C. prod. 3. p. 216. 



LIN. SYST. Icosandria, Monogijnia. Tube of calyx perma- 

 nent, obovate or globose (f. 118. a.), cup-shaped; limb in the 

 form of a lid, entire, cut round regularly at the base, and falling 

 oft' in one piece (f. 1 18. i.). Petals wanting. Stamens numerous 

 (f. 118. rf.), free. Capsule 4-celled (f. 118. c.), or only 3-celled 

 from abortion, opening at the apex, many-seeded. Tall trees, 

 natives of New Holland. Leaves quite entire, coriaceous, 

 usually alternate, rarely opposite, very variable even in the same 

 tree, quite glabrous except in a very few of the species. Pe- 

 duncles axillary, bearing an umbel of from 3-15 flowers. Flowers 

 white. The operculum of the calyx in some, according to Mr. 

 Brown, (gen. rem. p. C8.) is double, the outer in the form of a 

 calyx, and the inner the form of a corolla. There are about 100 

 species in New Holland (R. Br. gen. rem. p. 15.), of which 

 hardly a half are rightly known. In Van Dieman's Land a 

 manufactory has been established for the preparation of extract 

 of tannin from the bark of various species of Eucalyptus. A 

 considerable quantity of the substance has been recently im- 

 ported into England, and it has been said by tanners to be twice 

 as powerful in its operation as oak-bark.
