Eugenia lacustris C. B. Rob. in Philip. Journ. Sci. 4 (1909) Bot. 377. 
This is not the oldest use of this name, as in Chodat and Hassler’s Plantae 
Hasslerianae , 31 it is applied to two different species. While it would not have 
been given to the Philippine plant, had the facts been known in time, there 
seems no sufficient reason for displacing it, as in both of the Paraguayan eases, 
it can not be considered more than a nomen subnudum. Both have localities 
and collection numbers assigned, beyond this the first has only “Frutex 4-6 m. 
petala persicina,” and the second “Frutex 2-3 m. petala alba.” In the Plantae 
Hasslerianae, some ten species of Eugenia are indicated as new under names 
previously employed. 
Eugenia lutea sp. nov. %Jambosa. 
Arbor, Eugeniae jambos Linn, affinis : inflorescentiis corymboso-pani- 
culatis, divaricatis; floribus luteis, tetrameris, longe pedicellatis, calycis 
lobis conspicnis, persistentibns, petalis liberis, disco bene evoluto: foliis 
petiolatis, coriaceis, elliptico-lanceolatis yel oblongo-lanceolatis basi acntis 
decurrentibnsque, venis ntrinque 5 ad 9. 
Inflorescence terminal, corymbose-paniculate, 12 to 15 cm long, 11 
to 12 cm wide at the apex, trichotomous or some of the branches aborting, 
9- to 12-flowered, the peduncle 2.5 to 3.5 cm long, the ultimate pedicels 
16 to 30 mm long, 1-flowered; buds just before anthesis yellow, turbinate, 
2 cm long, 1.5 cm long to the base of the calyx-lobes and there 1.2 cm wide ; 
calyx-lobes 4, overlapping at the base, the outer pair 4 to 4.5 mm long, 
10 mm wide, the inner pair 7.5 mm long, 15 mm wide, all broadly rounded 
at the apex; petals 4, free, 10 to 15 mm long, 15 to 16 mm wide; disk 
well developed, circular in outline; filaments numerous; style (in fruit) 
up to at least 4 cm long : fruit urceolate, excluding the calyx-lobes, these 
persistent, suberect or spreading, incurved, coriaceous, their bases about 
1 cm above the insertion of the styles. 
A tree, about 20 m high, with a trunk 40 cm in diameter, the ultimate 
branches terete, with pale-cinnamon or yellowish bark ; petioles 1 to 2 cm 
long, lamina coriaceous, elliptic-lanceolate or oblong-lanceolate, 13 to 20 
cm long, 3 to 8 cm wide, the bases acute and decurrent, the apices probably 
shortly acuminate, both surfaces brownish or olivaceous, but the upper 
more shining; primary lateral veins on each side of the midrib 5 to 9, 
projecting moderately from the lower surface, nearly level with the upper, 
the midrib impressed on the upper and distinctly projecting from the 
lower surface, the veins in the basal half or two-thirds not uniting except 
by minor anastomoses and therefore not forming a definite submarginal 
vein.

Eugenia lutea seems to find its nearest ally among species of extra-Philippine 
distribution in E. jambos Linn., but more nearly approaches others supposed to 
Bull. Herb. Boiss. II 7 (1907) 806, 807.
