 ssepe muscis hepaticisque mixta. Caulis 2 cm. longus, vage 

 ramosu?. Folia recte patentia vix imbricata, late ovata, apice 

 rotundata; lobulus folio 3 brevior, oblongo-cylindricus, apice

This is one of the most remarkable plants of Colenso's 

 gathering ; I had found many years ago sterile plants mixed 

 with other New Zealand Hepaticae, but was uncertain as to their 

 affinity, the shape of the lobule being very different from that ot 

 other Lejeunea. The small size of the plant and the absence of 

 nearly all rufous colour remove it somewhat from the rest ot 

 liOpholejeunea, to which it, however, doubtless belongs on account 

 of its perianth, which in place of the usually lacerated marginal 

 wings has flat leafy scales, somewhat hooked at apex ; the upper 

 half of the perianth is bristling with them.
