Small or moderate-sized trees: 

 deciduous. Twigs stout, round: 

 pith large, round, continuous, 

 pale. Buds solitary, sessile, glo- 

 bose, with some half-dozen rather 

 loose pointed scales, the end-bud 

 lacking. Leaf-scars in whorls al- 

 ternately of two large scars and 

 one small scar, and one large scar 

 and two small scars, round-ellipti- 

 cal, raised; bundle-traces a dozen

 terete pods, with thin ciliate
