they are more likely to be found in such specimens as are just beginning to turn brown m their fructification, 
than in others more advanced. 
2169. Acrostic hum. Said to be formed from the words ocy^po? g-ixo?, the commencement of a verse, and to 
have been so called because the reverse of their leaves indicates traces of lines, resembling the beginning of 
lines of poetry. These are fine, chiefly tropical, ferns, one of which, A. aureum, sometimes grows to the 
height of five or six feet. 
2170. Hemionitis. Said by Dioscorides to be so called from the resemblance of its nature to that of a mule, 
ri/u,iovoi ; it was always considered sterile, bearing neither flowers nor fruit. 
2171. Gymnotiiamma. Named by Desvaux from yv/xvo?, naked, and y^a./ui.f/.ci, writing, in allusion to the 
disposition of the naked sori ui)on the forked veins of the frond, whence they seem to resemble Roman letters. 
The species have been separated from Hemionitis and Acrostichum. 
2172. Meniscium. From ij.yiv/i, the moon ; the sori are crescent-shaped. These ferns are remarkable for the 
arrangement of their veins. The little veins which unite the transverse veins of the sterile frond are usually 
at right angles, and generally united with each other by a little branch which sets off from one or other of 
their angles. In the fertile fronds the veins on which the sori are placed are either curved or straight. 
2173. Xiphopteris. Divided from Grammitis by Kaulfuss, who seems to have named it from |/<po?, a sword, 
and sTTE^til, a fern, on account of the sword-like form of their fronds. 
2174. Ceterach. The name employed by the Arabian and Persian physicians for this plant was Chetkerak. 
{Gaxoph. Ling. Pers. p. 377.) They employed the plant in obstructions of the viscera, for the jaundice, and 
for disorders of the spleen. 
2175. Polypodium. From TtoKus, many, and -xa; ro^og, a, foot, on account of the multitude of the roots which 
form close entangled patches. Many of the species of this genus are noble plants. They are mostly epiphytic
