be a Grammitis, which is characterized by Mr Brown as ha- 
ving the sori, “ venula unica insidentes, axi obliqui.” 
Whether or not the Grammitis graminoides of Swanrvz, 
above cited, be the same with the individual here figured, it is 
~ not easy for me to say. Its habit is similar; but it does not 
attain to more than half the size of the Tanitis graminifolia, 
not exceeding two inches in height, and it has the line of cap- 
gules very much shorter, forming an oblong cluster, “ costam. 
mediam seu nervum terminans.” I am, however, still much 
inclined to consider that plant as a small state only of the pre- 
sent; and if so, it unquestionably is not a Grammitis. 
The specimen here delineated was given to me, along with 
many other rarities, particularly of the Fern tribe, from the 
island of St Vincent’s, by my moend the Reverend Lanps-
