 dals in the 7"' internode. Interarticular pores to the 1 1"' internode. 

 Stem proximally narrower. The joints, especially the distal ones, 

 markedly pentagonal. Every second internodal joint provided with 

 an unbroken ring-crista. The infranodal face of the nodal joint lobate. 

 The sLipranodal joint somewhat incised by the cirrus socket. The 

 nodal joint a little thicker than the other joints. No distinct inter- 

 cirral tubercle.
