Trichomanes Henzaianum, Parish in litt. 



Hab. Detected by Mr. Henzai, and the Rev. C. S. P. Parish, 

 partially clothing the trunks of trees at Moulmein, 1859. 



Dr. Van Den Bosch, of Leyden, distinguished by his wri- 

 tings and admirable figures of Mosses, is now happily engaged 

 on a monograph, with numerous figures on the beautiful family, 

 among Ferns, of Hymenophyllacea. He has already given to 

 the world a valuable " Synopsis " of the group, with full de- 

 scriptions of new or critical species. Our present individual, 

 will rank near to TV. sublimbatum of Mueller, to which Van 

 Den Bosch refers, and probably quite correctly, my Java form 

 of Tr. muscoides, (Sp. Fil. i. p. 117). From that, however, 

 our plant may be known by its much smaller size, and different 

 form, greener color, more delicate texture ; but, above all, by 

 the involucre, of which the limb in T. sublimbatum extends to 

 the margin of the frond, while in our plant, the lobe of the 

 frond extends much beyond the involucre ; and has, indeed, the 

 appearance of half an involucre attached to the frond, as occurs 

 in not a few davalliaceous plants.
