A native of the Molucca islands; from thence intro- 

 duced into the Botanic i,';irden at Calcutta as a species of 

 Mangosteen. Flowering time in Bengal June and July. 

 The fruit ripens about the beginniug^ of the c«)ol season. 



The trees in the Botanic garden are but small, being

 smooth, olive-coloured. Branches and branchlets oppo-

 of trees eight years old about ten feet. Leaves opposite, 

 short-petioled, oblong, entire, often pointed ; texture hard, 

 both surfaces polished, about six inches long-, and from 

 two to three broad. Petioles short, transversely wrin-

 order (Guttifero.) Stipules none. Flowers in small fas- 

 cicles, from the axills of one or two-year old branchlets, 

 peduncled, of a middling size, or nearly globular, greenish 

 white, inodorous. Calyx of from four to five or six un- 

 equal, round concave leaves, as long as the stamina, con- 

 tracted into a globe, with a small opening at the apex 

 when most expanded. Nectary in the male, a truncated 

 porous, yellow body, with five lobes projecting between 

 the insertion of the five filaments. In the hermaphrodite 

 are five yellow porous glands, alternate with the filaments 

 round the base of the germ. Filaments in both, are five 

 incurved, broad, flat bodies divided at the apex into six,
