foot long, with stipes nearly half their length. They are lateral, indistinctly articulated with a slender creeping- 
rhizome. This plant was introduced in 1851, and was then referred to B. Bombeyanum, Fee. 
8. E. STincxrM, T . M. (Acrostic-hitm, BadcU ; Olfersia, Bred). — A delicate little stove species, 
received from "Wentworth, which we refer to A. slrictum of Eaddi, a native of Brazil. Fronds small ; the sterile 
ones four or five inches long, linear-lanceolate, narrowed above in a long point, and below into a short scaly stipes, 
the irpper surface clothed with silvery scales, the lower more densely with tawny scales, the scales lanceolate, and 
strongly ciliate. The fertile fronds are linear oblong-ohtuse, narrowed below in a long slender stipes, which is 
twice their length, and almost equalling the barren fronds ; upper surface densely lepidote with ferruginous scales, 
lower with a scaly midrib. 
9. E. HiHTUM, 31. and II. (Acrostiohum, Swartz ; A. vestitum, Zowe ; A. Loweanum, Iuwzo 
Herb-, Olfersia vestita, and 0. I’aleacea, Brest). —An evergreen warm greenhouse Fern, from Madeira. 
Sterile fronds linear-lanceolate, about a foot long, acute at the apex, attenuated at the base, and densely covered 
throughout with ciliated scales. Fertile fronds lanceolate, about a foot long, rather obtuse at the apex, attenu- 
,atcd at the base. Stipes elongate, and densely scaly. Fronds lateral, articulated near the base, with a short 
creeping scaly rhizome. 
XXII. STEXOCIIL^ENA, J. Smith. 
Sori amorphous, clenselj' covering the under surface of the fertile fronds. JUns (sterile) simple or 
forked, external; venules parallel, their apices exserted, forming cartilaginous serratures, or conniving 
and forming a thickened margin. Raehis-like part of rhizome, sometimes producing abnormal tripin- 
natifid sterile fronds. Fronds pinnate, or hipinnate, 
from one to four feet long, glabrous or squamose. Pin- 
nules (fertile) linear, narrow, the margin membranous, 
revolute and indusiform. Fhizome creeping. — Name 
derived from stenos, narrow, and chlainct, a cloak; allud- 
ing to the narrow membranous margin of the fertile 
pinnee. 
The species of this genus have a distinct and peculiar 
aspect, and form a very natural group. In habit they 
resemble Pohjhotrya, having a creeping scaly rhizome. 
The narrow linear segments of the fertile frond, with their 
indusiform margins, are analogous to what occurs in 
Lomaria ; but they differ materially from that genus in 
the margin being revolute, whereas in Lomaria it is 
jilane, and usually the axis of an indusium. Fig. 23 
represents a pinna of the sterile frond, with part of a 
pinna of the fertile frond of Stenochlvena scandens (med. 
size); for the latter we are indebted to Mr. Henderson, 
gai’dener to Earl Fitzwilliam, at Wentworth House, 
Yorkshire. 
1. S. SCANDEXS, J. Smith (Acrostichum, Linnwus\ Lo- 
M.VRiA, WilMenow, Olfersia, Brest \ Oxoclea, Swartz).— An. 
elegant evergreen stove Fern, with a scandent habit of growth, 
native of the East Indian and Malay Islands, and the Cape of 
Good Hope. Sterile fronds glabrous, shining, lanceolate, pinnate, 
somewhat pendulous, from three to four feet long ; pinnae linear- 
acuminate, cuneatc at the base, rather membranous, nearly a 
foot long, with a serrated cartilaginous margin ; veins simple 
or forked, parallel, connected at the base by arcuate costal veins, 
forming a row of long narrow areoles close to the midrib. Fertile 
fronds biplnnato; pinnse six to eight inches long; pinnules linear, 
narrow, and sporangiferous on the under surface. Both kinds 
of fronds are lateral, adherent to a scandent slender green 
rhizome, which is covered with long narrow scales, attached by their centre.
