C. PAPiLLosA, Euetz. — In 1893 were visited Heigham Sounds, 

 E. Norfolk, and a more extended examination of the Charas 

 orowing there led us to think that the plant we have recorded 

 under this name is a hybrid between C. hispida and C. contraria.

Stem slender, weak. Cortex imperfectly diplostichous, or some- 

 times quite rudimentary and consisting of single cells, but little 

 larger than the stipulodes, above and below each branchlet. Spine- 

 cells, when developed, short spreading or papillate. Stipulodes in 

 a double row, small, oval. Whorls of usually 6-8 spreading 

 branchlets. Branchlets of 4-6 segments, the ultimate segment 

 very short ; cortex rudimentary, represented by a ring of cells 

 at each fruiting node, the anterior cell often lengthening and 

 projecting below the antheridium. Bract-cells usually 6, anterior 

 1-11 times as long as the fruit, posterior very short. Fruits
