80 Anthelia 



Comparison of fruiting specimens reveals another character common to both, namely 

 the fleshy perianth ; but the uniformly acrogenous female flowers of jf. albescens, 

 and the cladogenous flowers oiLep. reptans — to say nothing ofother important differ- 

 ences in the leaves, &c. — forbid their union in the same genus. Both the glaucous 

 hue and the terminal inflorescence are found in Anthelia, which is perhaps the near- 

 est ally of P/^wrocZfl^rt ; although Hygrobiella laxifolia also stands in very close 

 relation to it. There is no Cephalozia which much resembles it in either habit or 

 character, or that could possibly be mistaken for it. Of all the Jungermanidese it has 

 perhaps the most fleshy perianth, sometimes as many as eight cells in thickness below 

 the middle.
