6. Arthrophyllum, Blume.

 the -lower large and compoundly pinnate, the uppermost opposite and

 rachis ; stipules forming a ligule within the petiole. Inflorescence a 

 terminal compound umbel, the terminal umbellules peduncled ; bracts 

 very small ; pedicel not jointed under the flower. Calyx-teeth 5, small. 

 Petals 5, valvate. Stamens 5. Ovary 1-celled, 1-ovuled ; style short,
