1923] Pearson: 3Iorc New Zealand Hepaticae 379 



branches narrowly pinnate, leaves very sq^^arrose, underleaves longer 

 than broad. Stephani, in his description, Sp. Hep., says: "appendix 

 subligulate, rotundate, connivent, lobule with large beak, underleaves 

 small, only a little broader than the stem, broadly obcuneate, lobes 

 apiculate; perianth obovate; bracts, lobe obovate-acute, lobule interior 

 margin coarsely lacerate, bracteole coarsely spinose. " 



F. rostellata Mitten, of which the original specimen was kindly 

 loaned to me by the Director of the Royal Botanical Gardens at Kew, 

 has leaves concave, not squarrose ; horizontally inserted, not vaginate, 

 larger cells with large trigones, ovate-oblong (1 mm. X -65 mm) ; 

 lobule very large, longly decurved, hooked with a long beak ; and has 

 underleaves with dentate margins; perianth obovate-oblong, laciniae 

 much larger and longer, 6 cells long, with beak very long. 



In F. Jacinaefiora, the minute lacinae with which the perianth is 

 clothed are unique, so far as observation goes. They are very minute 

 and numerous. I counted more than a hundred on the antical side 

 which are 3 cells long and 3 cells wide at their base, all pointing 

 upwards. The spores are also very singular, being regularly and 

 beautifulh^ tuberculate and having on their face 15 to 20 little circular 

 dots, which are more evident on the younger spores. The only capsule 

 I saw was hvaline with a short seta.
