Fig. 45. Asp. trich. ramosum. 



Ramosum, Wollaston (Fig. 45 and Appendix No. II). — A prettily 

 branched form, the frond tip dividing into several. This belongs 

 to the several forms of cristatum. 



Ramo-cristatum. — Several finds of this are recorded, in which 

 the characters of ramosum and cristatum combine to form heavy- 

 headed flat tassels of much beauty (see Appendix No. II). 



Troggyense, Lowe. — Found by Mr. Lowe in 1882 ; may be 

 described as a fertile form on incisum lines.
