XIPHOPTERIS serrunata, Ks. 
Serrated Xiphopteris. 
X1PHOPTERIS serrulata ; caudex a slender, scaly, more or less ascending and 
rooting rhizome ; fronds small, subhispid, tufted, on short stipites, two to 
four or six inches long, more or less curved or flexuose, linear, attenuated 
below, deeply pinnatifid, the segments subovate or dentiform ; fertile ones 
bearing the sori on the changed, caudate, and generally more or less entire, 
usually falcate extremity, the very apex sometimes sterile and pinnatifido- 
serrate ; veins solitary in each lobe, soriferous in the fertile portion, sori 
soon confluent. ’

all travellers. Mauritius, on the trunks of trees, Bouton, in Herb. Nostr. ; 
Bojer also records it as a native of Bourbon and Madagascar, which is quite 
likely. Sandwich Islands, Menzies, in Herb. Nostr. Juan Fernandez,

There is a peculiarity in Xzphopteris, besides the altered form 
of the portion of the frond which bears the fructification, that 
induces me to retain the genus; but in regard to the species, it 
seems to me that the two forms serrulata and myosuroides 
gradually pass into each other, and are often seen on the same 
frond. Others may think my X. Jamesoni (‘Second Century of 
Ferns,’ t. 14) not more worthy of specific distinction. I have 
stated my views on the subject, and the habit of the plant indi- 
cates something peculiar. In respect of Xzphopteris setosa, 
Kaulf. En. Fil. App. p. 274 (Grammitis, Pr., Polypod. Metten., 
Grammitis myosuroides, Raddi, not of others), I should be dis-
