This is a list of Syzygium, from "Bengal Plants", meaning mainly covers the distribution in and around the 'Bengal during British era'.
Thank you.

My first question is - why the book "Bengal Plants" by Sir David Prain, published in 1903, didn't enlist Syzygium samarangense in any synonymous form?
Two decades later, in 1925, Dr. Haines, in his "Botany of Bihar and Orissa" listed one - Eugenia javanica Lamk., syn. E. alba Roxb.; JAMRUL, Beng. And he noted, " Cultivated only in the southern moisture districts, e.g. Cuttack, Fl. April, Fr. May, Native of Malacca."
So, who is this apparently lesser known stranger E. javanica Lamk.?
"The Plant List" says it is Syzygium samarangense - http://www.theplantlist.org/tpl1.1/record/kew-75559!
"KEW" says it is Syzygium aqueum - http://www.plantsoftheworldonline.org/taxon/urn:lsid:ipni.org:names:594758-1!
!!!!! Confusion confusion confusion !!!!!
A 2015 paper on revision of Syzygium ....., (NOT an Indian Paper) relates E. javanica Lam. with S. aqueum (Burm. f.) Alston.
My second question is - why should our JAMRUL be tagged with Syzygium samarangense??? The ground is, as per eFI -
Key characteristics: Trunk short, crooked, often branching from base; crown irregular; leaves opposite; flowers yellow-white;
... aqueum: 5–15 mm long leafstalk and 5–7mm long calyx, small fruits;
... samarangense: 3– 5mm long leaf stalk, 15mm long calyx and larger fruit; aromatic
... aqueum: 5–15 mm long leafstalk and 5–7mm long calyx, small fruits;
... samarangense: 3– 5mm long leaf stalk, 15mm long calyx and larger fruit; aromatic

!!!!! Confusion confusion confusion !!!!!
What the paper says?
Leaf subsessile, petiole ≤ 2 mm long; leaf base cordate; hypanthium apex abruptly constricted to pseudostalk;
fruit turbinate (in vivo) .......... S. aqueum (Burm. f.) Alston
Leaf petiolate, petiole > 2 mm long; leaf base cuneate, rounded or slightly cordate; hypanthium gradually constricted to pseudostalk; fruit pyriform to subglobose (in vivo) ................. S. samarangense (Blume) Merr. & L.M.Perry
And the paper also notes, ".... S. samarangense and S. aqueum are widely cultivated in the tropics ranging from India through ....... This is further complicated by some overlapping vegetative characters between the two species ......."
Thank you.
