A shrub or small tree, branches slender. Leaves 3-5 by 1-1} in., green when dry 
with pale midrib nerves and sometimes margins ; petiole 1-4 in. ; stipules 4 in. and 
less, ovate, acute or with subulate points. Cymes very variable, rarely sessile; 
branches opposite, usually long, spreading, slender and trichotomously divided at 
the top with short divisions ; bracts, bracteoles, and flowers very small. Calyx-teeth 
triangular. Corolla-tube short, throat villous. Fruit lin. sometimes truncate, not

of the Western P. bisulcata. Kurse Martaban specimens have much shorter and 
stouter cyme-branches than the Khasian.
