tains a number of choice things. .Of course there are. several 
common species which grow throughout the Antillean.and South 
American tropics, such as Polypodium Phyllitidis and P. Plumula, 
Dryopteris trifohatum and D. macrophyllum, Nephrolepis acuta 
and J. exaltata, Asplenium serratum and A, cicutarium. But along 
with these are others by no means.so common, some. of which are 
deserving of special mention, - lenges 
The first of these in importance as well as interest is a new 
Gymnogramme belonging tothe sub-genus Se/liguea. Mr. Squires 
was particularly interested in collecting. ferns and other crypto- 
§@ms, and this species was gathered by him on the last day of the 
€xpedition, after all their other specimens were packed up. As 
Dr. Rusby says: «It was fired into a bale of paper on the fly, 
and dried itself. Two or three times afterward it was dropped 
aside and all but lost ; and it seems quite remarkable that it should 
have survived for a description.” Fortunately the specimens were 
finely fruited and.complete in every respect; and they enable me | 
to present herewith a full description of the plant. 
GyMNOGRAMME (SELLIGUEA) HETEROPHLEBIA N. sp. 
Rhizome wide-scandent, the younger part thickly clothed with 
long (14 in.) lanceolate acuminate bright brown.scales, the stipes 
Springing directly from the rhizome, the older portion of rhizome 
bearing short branches on which the stipes are tufted. 
Stipes single or two to three in a cluster from the same short 
branch of thizome, when single 34 to 1% in. apart, 14 to 1 in. 
long, clothed at base with same scales as rhizome. 
Rachis distinct from base to tip stramineous naked. Frond § 
-8 in. long, 7-144 in. broad, lanceolate-ovate point generally 
acuminate, but sometimes round and blunt, surfaces naked, edge 
€ntire or slightly wavy, lower part of frond shortly narrowed into 
Stipe ; color light brown, texture membranaceous. __ 
Veins of two kinds, primary ones raised, very distinct, running 
in wavy line from rachis two-thirds of way to edge. Also a finer 
Series forming irregular areoles between the main veins with oc- 
casional free veinlets included, exterior veinlets free and clavate 
just within the edge. : 
Sori extending in two series from base to tip, one sorus in
