A large deciduous tree ; branchlets four - sided and channelled, with 

 large quadrangular pith. Leaves oval or obovate, blade 1-2 ft. long, 6-12 

 in. broad, petiole 1-1 J in. long, in seedlings and coppice-shoots the leaves 

 much larger, 2-3 ft. long; upper side rough, under side clothed with 

 dense stellate, grey or tawny tomentum ; main lateral nerves prominent, 

 8-10 pair, with 2 or 3 large branches near the edge of leaf, joined by 

 numerous parallel transverse veins. Flowers white, on short pedicels, 

 in large erect terminal cross-branched cymose panicles 1-3 ft. long, with 

 short lanceolate bracts. Fruit subglobose, more or less indistinctly 4-lobed, 

 J in. diam., the thick spongy pericarp consisting of a dense felt of branched 

 hairs ; the nut uneven, with 1, 2, 3, rarely 4 seeds, and a central cavity 

 having the appearance of a 5th cell. When the seed germinates, the outer 

 wall of each cell comes off bodily like a round, concave cap. The inflated 

 calyx, enclosing the fruit like a bladder, is generally ovoid, sometimes de- 

 pressed, reticulate, and more or less crumpled or irregularly plaited, 1-1 J 

 in. diam.
