Gnetum montanum (Gnetaceae), a woody liana belinging Gymnosperm group, commonly found in Manipur forests. Ripe ‘fruits’ are attractively coloured, perhaps eaten by birds.
Gnetum montanum Markgraf, Bull. Jard. Bot. Buitenzorg, sér. 3. 10: 406. 1930.
Vines to more than 10 m tall; branchlets orbicular or compressed orbicular in cross section, smooth, sometimes wrinkled longitudinally. Petiole 0.8-1.5 cm; leaf blade usually oblong, sometimes oblong-lanceolate or elliptic, 10-25 × 4-11 cm, leathery or nearly so, lateral veins 8-13 on each side, base rounded or broadly cuneate, apex obtuse to acute. Male inflorescences lax, once or twice branched, 2.5-6 cm; peduncle 6-12 mm; male spikes 2-3 cm × 2.5-3 mm, involucral collars 13-18, each collar with (20-)25-45 flowers plus 10-15 sterile female flowers, basal hairs forming a dense, short cushion. Female inflorescences lateral, solitary or fascicled, main axis thin, with 3 or 4 pairs of branches; peduncle 2-3 cm; female spikes 2-3 cm × ca. 4 mm, enlarging to ca. 10 cm when mature, nodes each with 5-8 female flowers, basal hairs sparse, short. Seeds yellowish brown or reddish brown, cylindric-ovoid or cylindric, (1-)1.2-1.5(-2) cm × 6.5-9(-12) mm, 1.6-1.85 × as long as wide, base rounded, sometimes contracted into a stipe to 3(-5) mm, outer coat smooth or ± longitudinally wrinkled when dried, sometimes covered with silvery scales. Pollination Apr-Jun, seed maturity Aug-Oct.
The fibers from the bark of the stem are used in making gunny bags, fishing nets, and ropes; the seeds yield an edible oil, are eaten fried, and are used for making wine; the sap is used as a cold drink.
Thank you … for these wonderful pictures. Gnetum ‘s ‘fruits’ are all pulpy, does any other Gymnosperm have such pulpy seeds?
I don’t think that Gnetum fruits are pulpy rather the mesocarp is filled with very fine fibers. If you try to chew or handle you get all the “spiny” fibers on your mouth/body. But I have seen Hornbills and Barbets eats the fruits but no post dispersal predations is noticed so far in my observations.
Thanks for sharing your observations … I have not seen the fruiting at all so my inference is only from the pictures. But my question is does this kind of look of the seeds of Gynosperm occur in other species of Gymnosperms or is it unique to Gnetum species only?

btw, G. funiculare Kurz = G. funiculare Blume (FBI)
and G, funiculare Wight Ic. t. 1955 = G. scandens Roxb.
Encyclopedia of Flora and Fauna of Bangladesh (EFFB) mention three species of Gnetum found in Bangladesh
2. G montanum Mgf.
Synonym: G scandens
In Bangladesh it found in the forest of Sylhet and Chittagong District
3. G. oblongum Mgf.
Synonym: G. funiculare Wight (1955)
Encyclopedia of Flora and Fauna of Bangladesh (EFFB ), Vol-1 to 28 (6-10 Angiosperm_Dicot), (11-12_Monocot); (5_Bryophyte, Pteridophyte and Gymnosperm) is the updated version and this book flowed by FBI of Hooker and BP of David Prain

Unfortunately I have only century old lit., …, and revision, updation of species is a continuing process.
Dear … I am agree with you regarding revision update.
This time with fruits
