SpeciesWoodVesselsWood ParenchymaXylemFibresAtalantioxylon indicum LakhanpalDiffuse porousVessels medium to large in size, up to 350 µmAxial parenchyma absent or extremely rare, paratracheal parenchyma scanty, forming few cells around the vesselRay width 1 to 3 cells; all ray cells procumbent, 4-12 mmNon-septateAtalantioxylon thanobolensis sp. nov.Diffuse porousVessels small to medium in size; tangential diameter 45-134 µm; radial diameter 67-180 µm; solitary and in radial multiples of 2-5, evenly distributed over 24-30 mm2Parenchyma paratracheal, terminal and apotracheal; apotracheal diffuse; paratracheal sparse, present as few cells around some of the vessels; terminal parenchyma forms 2-3 seriate continuous lines demarcating the growth ringXylem rays fine to medium 1-3 (mostly 2) seriate, over 5-7 mm2; 8-34 cells 80 -550 µm long separated by rows of fibers. Rays cells polygonal in tangential section often with dark content; ray tissue homogeneous made up of procumbent cellsNon-septate
