HooKEBiE^a:. — JT. lucens never changes : in winter and summer 

 it is alike "beautiful. It is now fruiting pretty freely. 



FoxTiifALE^. — _F. antipyretica fails. 



Hepatic-^;. — Riccia Jluitans grows in a very interesting way. 

 Targionia Jiypophylla is gone. The March(mti<Jd grow too freely. 

 Jungermannim : I have had twenty-seven species ; some of them, 

 e. g. tT". tomentella, «/". ciliarisy J. spinulosa and J", asplenoides, are 

 as beautiful as any plants in the case. Some of the species fruit 

 profusely, pouring out a stream of silvery translucent fruit-stalks, 

 tipped with little snining ebony heads, which, when expanded, 

 show very remarkable hygrometric properties. J", nemoralis is 

 covered with little dark-coloured gemmae. 



Sartramia Salleriana grew last autumn with a Jfringe of Hyme- 

 nophyllum^ with which it was collected near Loch Lomond, and 

 was as round and as finelv in fruit as a bush of Mistletoe.

 has long been a matter of doubt, and indeed continues to the pre-

 by some regarded as exalbuminous, while others represent the 

 embryo as lying in the axis of copious albumen.
