 four principal lobes or branches, from half an inch 

 to an inch in breadth, and fi*om one to four inches 

 long-, attenuated at base, thence cylindrical till near 

 the tip, when they ag-ain slightly taper. In sub-

 membrane being* very thin and of a pale rose-colour. 

 3. lati folia. Frond twelve to twenty inches long-, 

 twenty-four inches wide in the widest part, rising- 

 from a minute stem, wedge-form, either simple or 

 forked, or once or twice regularly cleft in a palmate

 destitute of ramuli ; of a dark-red colour and soft, 

 but not very g-elatinous substance (very similar in 

 feel to Kallymenia reniformis) ; perfectly flat, the 

 stratum of g-elatine interposed between the mem-

 abundantly scattered over every part of the frond, 

 and to the naked eye resembles minute dark-red
