parva angusta septicicle dehiscens polysperma. Semina minutius- 

 cula reticulata areola obliqua foveolata. 



Arbor v. frutex ramulis subteretibus. Folia membranacea. 

 Stipulse latne cleciduae in dentibus triangularibus bifidae. Flores 

 inter minores in cymis unilateralibiis subcorymbosis terminalibus 

 sessiles. 



The genus clearly finds a place in the tribe RondeletiecB, but it 

 is distinct from the rest of this tribe in the basal insertion of the 

 stamens, the bifid stipules, and the combination of contorted 

 aestivation with petaloid development of one or more of the calyx- 

 lobes. Fallasia seems to be the nearest ally, but in Pallasia the 

 aestivation is imbricate, and the stipules entire.

NOTE ON LEUCOBBYUM. 



By E. M. Williams. 



I CAME across lately in some woods near Fawley, Hants, 

 many unattached cushions of moss. Some of these cushions 

 were sent to a competent authority, who pronounced them to be 

 abnormal growths of Leucobryum glaucum. As there appear to 

 be but few previous records of the occurrence of these double 

 discs of moss in England, a short description of them and of their
