Bitten-flomered Eugenia. Shrub. 



N. B. There are numerous names of species in Roxburgh's 

 Hortus Bengalerisis, but all without descriptions. 



Eugenia villosa, Poir. suppl. 3. p. 124. or My'rtus villosa, 

 Spreng. syst. 2. p. 487. is obviously the Monimia rotundifolia, 

 Pet. Th. or Ambora tomentosa, Bory ; a plant belonging to 

 Urticece. 



Eugenia violacea, Lam. diet. 3. p. 200. is evidently a Rubia- 

 ceous plant, and perhaps an Exdra mixed with the leaves of a 

 species of Syzjjgium in M. Jussieu's herbarium. 



Cult. For culture and propagation see Jambosa, p. 869. 



XXXIV. JAMBO'SA (altered from Schambu, the Malay 

 name of one of the species). Rumph. amb. 1. p. 121. D. C. 

 prod. 3. p. 286. Jambos, Adans. fam. 2. p. 88. Eugenia spe- 

 cies, Swartz, Kunth. 



LIN. SYST. Icosandria, Monogynia. Tube of calyx turbinate (f. 

 124. a.), attenuated at the base, having the throat drawn out be- 

 yond the ovarium, dilated and obovate ; limb 4-cleft ; lobes round- 

 ish. Petals 4, inserted in the throat of the calyx, broad, concave, 

 obtuse. Stamens very numerous (f.124. b.\ longer than the petals, 

 free, straight. Style filiform ; stigma simple, acutish. Ovarium 

 many-celled, many-ovulate. Fruit 1-2-seeded, fleshy from the 

 large baccate calyx, umbilicate at the apex. Seed angular. Co- 

 tyledons fleshy, thick, with conferruminated margins. Radicle 

 almost cylindrical, hidden between the cotyledons. Indian trees, 

 with opposite leaves, standing on short petioles, and full of 

 pellucid dots. Cymes lateral and terminal, few-flowered, sim- 

 ple, much shorter than the leaves ; pedicels lateral, opposite, and 

 one terminal. Flowers large, bractless, articulated on the tops 

 of the pedicels. Fruit large, eatable. The greater part of the 

 species being cultivated for the sake of their fruit are therefore 

 difficult to extricate from confusion. 



1 J. VULGA'RIS (D. C. prod. 3. p. 286.) racemes cymose, ter- 

 minal ; leaves narrow-lanceolate, attenuated at the base, acumi- 

 nated at the apex. Ij . S. Native of the East Indies, and now 

 cultivated in all the regions within the tropics. Malacca-

 Leaves 6-7 inches long and 1 to 1^ inch broad. Fruit ovate- 

 globose. Flowers white. The Jamsorade or Rose-apple is a 

 branching tree, about 20 feet high. The fruit is pear-shaped, 

 about the size of a medlar, white, red, or rose-coloured, and 

 ripening from September to December. There are several 

 varieties differing in the size and colour of the fruit. It is not 

 so much esteemed as the Malay-apple : it is however neverthe- 

 less excellent, resembling in appearance and flavour a Brussels 

 apricot. To grow the fruit in this country, it requires a hot 

 and moist atmosphere.
