Flowers borne in terminal or less often lateral cymes, rarely upon the 
older branches, the individual cymes 3-5-flowered, 4-10 cm long, the 
peduncles and pedicels slender, the latter 7-32 mm long; pseudostalks at 
anthesis 5-6 mm long, calyx-tube about 3 mm long, turbinate, about 7.5 
mm in diameter at the base of the 4 lobes, the lobes slightly unequal, 
semicircular, 2.5-3 mm long, 5-6 mm wide at the base; petals 4, sub- 
orbicular, 8 mm in diameter, rounded at the apex; staminal disk well 
developed ; stamens numerous, the filaments exceeding 1 cm in length; 
the anthers 1.2 mm long; ovary 2-celled, each cell containing numerous 
small ovules, the ovarian wall just within the margin with a conspicuous 
row of oil-glands; fruit white to reddish, attaining a diameter of nearly 
1.5 cm, the pseudostalk usually reduced to about 1 mm, the calyx-lobes 
persistent, conspicuous. 
A tree 15-20 m high, with trunks about 25 cm in diameter, the 
ultimate branches covered with grayish or reddish bark; leaves borne on 
petioles 2-8 mm long, the lamina chartaceous, elliptic or oblanceolate, 
8-13 cm long, 3-4.8 cm wide, acute or shallowly cordate at the base, at 
the gpex acuminate, usually sharply, often conspicuously glandular-punc- 
tate; primary lateral veins on each side of the midrib 9-13, usually 
forming two definite submarginal veins. 
The original description of Myrtus tripinnata contained many errors, as Blanco 
liimself recognized before the publication of the second edition. In many ways 
the species suggested is Eugenia luzonensis Merrill, but one point seems to be 
conclusive as showing its difference from that species. The flowers are said to 
form a terminal umbel, whereas in E. luzonensis they are never entirely terminal, 
and only one collection has been found on which they are partially terminal. 
They are very widely paniculately disposed, the single flowers umbellate, sessile 
or subsessile, whereas those of the species here described as E. tripinnata, though 
not truly umbellate, might be roughly so characterized. They also are more often
