preceding by its smaller leaves sharply spiculated, with fewer nerves and a longer 
petiole, a much shorter and stouter raceme. Its leaves are 5-6 in. long, 24-23 in. 
broad, on a petiole 8—5 lines long; the rachis of the raceme is 13 in. long, and bears 
alternate flowers 2-1 in. apart, on pedicels 2 lines long. The flowers had all fallen away, 
leaving some half-grown ovaries or immature fruits 7 lines long, crowned by 4 calycine 
lobes 3 lines long. 
4. STRAYADIUM. 
This genus is maintained by very efficient and unmistakable characters. It was 
established by Jussieu іп 1709! upon the Zsjeria Saamstravadi of Rheede’ and a few other 
species. It was acknowledged by Blume? and DeCandolle *, but rejected by Roxburgh 
and other botanists, who conjoined it with a group of species under a genus called 
Barringtonia, very different from the true Barringtonia of Forster; and hence have 
arisen the many complications that followed. Miquel attempted a monograph: of the 
family?, which has created still further confusion among the species. He enumerated 
under Barringtonia 17 species*, apportioning them into 2 sections, Butonica and 
Stravadium, after the example of Endlicher', by characters so loose that he quite 
disregarded them in the arrangement of his species, and he thus rejected Stravadium as 
а genus. Blume at a later period stil acknowledged Stravadium*, enumerating 
11 species, the first 6 of which only can be retained. The authors of the * Genera Plant- 
arum ' adopted entirely? the views of Miquel. 
We must attribute all these discrepancies to the entire disregard shown by most 
authors to the structure of the free portion of the calyx. Тһе difference is well marked 
in several cases, where this free portion is vesicular and entire in the bud, but is soon 
ruptured by the pressure of the petals into 2, 3, or 4 lobes, which are either very large or 
moderately small—characters constant in the genera Barringtonia, dgasta, and Butonica ; 
on the other hand, in Stravadium this calycine border is divided, even in the bud, into 
4 small rounded ciliolated sepals, somewhat imbricated in sestivation, as in Carya and 
Planchonia. Tt is easy, therefore, without the possibility of mistake, to detect at once 
any species of Stravadium, a genus distinguished by the presence of 4 free sepals in the 
calycine border, an ovary constantly 2-celled, with 2 suspended ovules in each cell, 
producing an oblong, subtetragonous, indehiscent fruit, which by abortion is 1-celled, with 
à single large seed that fills the cell, and that consists of an exalbuminous embryo, like 
that already described іп Butonica. se : 
We may regard the Eugenia acutangula of Linnzus as the type of the genus, with 
Which many other different species have been confounded by botanists under the name 
of Barringtonia acutangula.
