Jambavam), a large tree with light gray bark. Leaves elliptic - 



lanceolate, acuminate, coriaceous; secondary nerves running 



closely parallel and meeting in one 

 just inside of, and parallel to the 

 margin. When held up to the light 

 small transparent dots are seen: these 

 are marks of a volatile oil contained 

 in glands: when the leaves are bruis- 

 ed, the scent of that oil will be noticed. 

 Flowers in their morphological struc- 

 ture are like those of the Guava, the 

 deciduous petals and the slender hla- 

 ments of the numerous stamens being 

 particularly noticeable. The latter 

 make the flowers showy (compare 

 the flowers of Acacia, page 42). In- 

 florescence cymose on the previous 

 year's wood. Fruit a one-seeded 

 berry, edible. 



3. Several species of the genus 



Eugenia are found on the hills; the commonest in the plains are 



E. corymhosa (Kan. Kuntala; Mai. 



Neral), E. zeylanica {Kan. Gudda- 



panneralu, fig. 49) both yielding a 



very good fuel-wood. The fruit of E. 



malaccensis (Rose-apple) is eaten, and 



from the E. cm^yoplujUata we obtain 



the well-known spice, Cloves (fig. 51). 

 4. The Blue Gum Tree {Euca- 

 lyptus globulus) and other species of 



the genus Eucalyptus, indigenous in 



Australia, are now cultivated in India, 



chiefly on the hills, on account of 



their rapid growth, producing a great 



quantity of fuel. The leaves are 



opposite, sessile, cordate, glaucous- 

 gray, and horizontal in saplings, but alternate, petiolate,
