is it a shrub or a tree?

Small tree!

May be Syzygium cumini (L.) Skeels as per comparative images at Syzygium & as per checklist of Nepal.

Is the flowering period ok. It has not yet flowered.
Syzygium cumini

Check with observations in efi site.

Flora of Bhutan gives flowering as Feb. to August. I think this may be both flowering and fruiting time.

On checking with keys in Flora of Bhutan at Syzygium, there is another closely related species as per keys at
Calyx tube 4—5mm, cup suddenly contracted into stalk-like base; stamens 4— 7mm…………………………………………………………………………….. 8. S. venosum
Calyx tube funnel-shaped, tapering and not suddenly contracted into stalk-like base ……………………………………………………………………………… 10. S. cumini
Flora of Bhutan mentions, Fl. -Fr. time as June to November. So S. venosum is possible. It also gives its habitat as Warm broad-leaved forests and river banks in dry valleys, 300- l410m, while for S. cumini it gives Subtropical and warm broad-leaved forests, 200— 1580m. February —August.
However, I am unable to decide based on the above keys.
Complete description of S. venosum is as below:
Tree 6- 25m. Leaves leathery, elliptic to obovate, 8 — 12 x 2.5 — 6cm, abruptly acuminate or caudate, base attenuate, glossy above, veins numerous, slender, weakly prominent on both surfaces, intra-marginal vein conspicuous; petiole 1.1 2cm. Cymes terminal and axillary, 4 — 8cm diameter, many-flowered; peduncle 2 —6cm. Flowers sessile. Calyx 4—5 x 4—5mm, cup abruptly narrowed into stalk like base, very shallowly lobed. Petals white, -4mm, shed together as flowers open. Stamens cream, 4 – 7mm. Style c 4mm. Fruit obovoid, c lcm, fleshy when ripe, pinkish crimson.
Complete description of S. cumini is as below:
Tree to 25m. Leaves coriaceous, elliptic, sometimes ovate or obovate, 6— 13 x 3—6cm, acuminate, base cuneate, veins numerous, intra-marginal vein +/-conspicuous; petiole 1.5—2cm. Cymes borne in axils of older and fallen leaves, c 8cm diameter, many-flowered; peduncle 0.5 — 10cm. Flowers sessile. Calyx funnel-shaped, tube 3 — 5 x 2 — 3mm, tapering into stalk-like base, lobes shallow, persistent. Petals creamy, 2mm, shed as a cap. Stamens 2 — 5mm. Style 2 — 4mm. Fruit obliquely obovoid, l x O.6cm, crimson, becoming black when ripe.
Recently published book the Dept of Plant Resources, Govt. of Nepal
has added following sp also besides listed in the ACFPoN :
S. formosum
S. kurzii
S. nervosum

Question is how to verify with the keys as other aspects look similar.

For me it is even difficult. Just I can guess.

can the book be purchased? is there website for it? r
could you please give citation for the book including ISBN and full name of book, authors, publisher etc

Yes …! around INR 500 each and less.

we need to figure something out, will ask …

…OK !

Same plant on 19 January 2020 !
5 images- 6 to 7 mb each.

Thanks, …, What do you say about the id as per key?

Not yet sure …!

Pl. check the calyx of S. cumini also.

ACFPoN says : Fruit red to black, ellipsoid to pot-shaped, 1-2 cm, 1-seeded; persistent calyx tube 1-1.5 mm. Fl. Feb-Mar or Apr-May, fr. Jun-Sep.

Secondary forests on level areas, wastelands, streamsides; below 100 to 1200 m.

I think this confirms it as S. venosum
Calyx tube 4—5mm, cup suddenly contracted into stalk-like base; stamens 4— 7mm ………. 8. S. venosum
Calyx tube funnel-shaped, tapering and not suddenly contracted into stalk-like base ….. 10. S. cumini

Thank you …! I was with the same opinion !
