A species ambiguous in its relations. Blume places it next to his Barringlonia 
racemosa, which is numerous in synonyms, the chief of which is his var. elongata, the 
type of this genus. Miquel’s description of this species is а mere repetition of Blume's 
unsatisfactory diagnosis. It appears to me to belong to Megadendron, not only on 
account of the country of its origin, but its general habit, its long pointed cuneated leaves, 
suddenly rounded at base upon an extremely short petiole, a terminal long raceme, 
with an erect thickened rachis—characters peculiar to the genus to which I have assigned 
it. Blume and Miquel refer it to the Barringtonia acutangula, Spanaghoe, a species 
known by name only, without any given character, and evidently unknown to them. 
Blume states that the leaves in this species are 4-10 in. long, 11—41 in. broad, on petioles 
only 2-3 lines long. Хо other dimensions are given. 
10. CHYDENANTHUS. 
This new genus! is founded upon a plant which differs from all others of the family in 
having a branching panieulated inflorescence, and which was originally described by 
Blume in 1826 under the name of Barringtonia or Stravadium excelsum. It is a native 
of Java, a lofty tree, with broadly spreading branches and long pointed leaves; the 
terminating panicle, longer than its large leaves, has alternate branches, presenting at 
rather short intervals alternate very prominent nodes, each having articulated upon it a 
sessile ebracteated flower of moderate size: the calyx is peculiar, of a cup-shaped form, 
with an almost entire margin, broadly open in the bud; it has 4 oblong petals, attached 
by their claws to the staminiferous tube as in the other genera; there is a peeuliarity in 
the staniens in having most of the filaments antheriferous, while the 2 or З inner rows 
are reduced to the form of slender barren pointed hairs: the inferior ovary is cylindrical, 
8-grooved, 2-locular, with a single ovule erect in each cell : the fruit, according to Blume, 
is like that of Stravadium in form.
