(Lotzea, Klotzsch and Karsten ; — Asplenii sp. Auct ; — Scolopendrii sp. ;— Allantodeae. sp. Aiict ; — Callipteridis sp. Sory ; — He- 
mionitidis sp. iSwa7'tz ; — Anisogonii sp. Hooker ; — Microstegise sp. Fresl j— Hypochlamydis sp. Fee ; — Athyrii sp. Auct.) 
Sori indusiatc, linear all or the lowermost only double, i. e., the receptacles occupy both sides of the veins. Indusium narrow, 
membranaceous, plane or fornicate ; in the double sori affixed in pairs back to back on opposite sides of the same venule, orfe opening 
anteriorly, the other posteriorly ; in the simple sori, as in Asplenium. Veuis simple or forked from a central costa ; venules direct free. 
Fronds herbaceous or coriaceous, simple pinnate or variously compound. Rhizome short, erect, rarely sub-arborescent. (The 
limit between Asplenium and the present genus is not very definite, in consequence of some species having but few of the double sori, not- 
withstanding which Diplazium has been almost universally admitted since the time of Swartz, by whom it was founded). (Moore.) 
1. Diplazium lasiopteris. (Kunze.) Caudex creeping with wiry roots compactly scaly at the apices of the branches, stipites a 
span and more long, brown scaly and hispid, fronds 8 to 12 inches long ovato-lanceolate acuminate membranaceous pinnate, pinnatifid 
at the apex pinnse 2-5 inches long, to | inch wide, sessile from an obliquely truncated auriculate base linear-lanceolate acuminate more 
or less deeply pinnatifid, segments falcate more or less serrated and generally with an incurved acumen, hairy above, glabrous below, 
except on the costa, veins pinnated in each segment, veinlets simple or rarely forked, nearly all soriferous, lower ones double. Kunze Fit.

(Asplenium Thwaitesii (C. P. 134.3) a specimen of which has been forwarded me by Mr. Thwaites from Ceylon seems hardly 
distinct— the large bi-pinnate species (C. P. 3100) is quite distinct from this). 
Pulney Hills— very abundant about Poombarry. — Nilgiris, near Ootacamund rare.

2. Diplazium syhaticum. (Presl.) Caudex stout erect woody sending down very stout unbranched vermiculate fibres, pale- 
aceous at the summit with rather large almost black subulate scales ; stipes a span to a foot long stout scaly only at the base, fronds 
feet long ovato-lanceolate sub-membranaceous, pinnated, pinnatifid at the apex, pinnre below petiolate horizontally patent from a 
generally truncated base elongate oblongo-lanceolate acuminate sub-falcate entire or sub-sinuate or sub-pinnatifido-lobate rarely sub-auri- 
culate at the superior base, lobes rounded entire or serrated, veins fasciculato-pinnate in the lobed pinn^ each fascicle corresponding to 
a lobe, sori very slender, lower ones or more double. Hooker Sp. Fil. iii. 248. — Presl. Rel. Ha^nk. i, p. 42. 
Nilgiris— abundant down the Sisparah ghat. 
PLATE No. CLXI. 
3. Diplazium dilatatum. (Blume.) Caudex stout woody erect, stipes stout 2 feet and more long below paleaceous with lan- 
ceolate acuminate scales, fronds glabrous very large membranaceous or coriaceo-membranaceous tri-pinnate below with the pinnules often 
deeply pinnatifid (hence sub-tri-pinnate) pinnate above, and pinnatifid at the apex ; pinnaa more or less petiolate, again pinnated or 
pinnatifid with the pinnules or segments from simply crenated or even entire to deeply pinnatifid, very variable in size, veins pinnate 
simple or forked never imiting, sori narrow linear not extending to the margin, lower ones double, Blume En. PI. p. 194 ; — Asplenium

(This and the last species are both very variable, it is doubtful if the two are really distinct.)
