“…Affinities-The important features of the fossil, viz., diffuse porous wood, presence of vertical gum canals, vasicentric tracheids, almost exclusively solitary vessels, non septate fibres and broad xylem rays with heterogeneous ray tissue strongly indicate its affinity with Dipterocarpaceae (Hie, 199.1; Kribs, 1959;Metcalfe & Chalk, 1950;Miles, 1978;Pearson & Brown, 1932). The family can be divided into two groups (Ghosh, 1958) on the basis ofthe arrangement ofgum canals: (i) gum canals always in concennic rings (e.g., Shorea, Doona, Hopea, Parashorea, Pentacme, Balanocarpus and Dfyobalanops) and (ii) gum canals diffuse, solitary and in short tangential rows (e.g., Anisoptera, Dipterocarpus, Vatica, Vateria and Cotylelobium). As gum ducts in the present fossil wood are ofdiffuse type, it can be compared with the genera of second group.…”
