Nilgiris common in woods about Ootacamund. 
Very similar to the last species in oiitivard appearance, the venation hoivever is different, and the under-siirface of the frond is 
ahoays clothed with orbicular p)dtate scales. The venation is only to he detected by soaking the frond, it is then much more prominent than 
that of P. Wicjhtiana. The venation is more tluit of Phlebodium than of Pleopeltis, and there is sometimes a narrow areole formed near 
the costa within the large elongated areole ; this areole, however, is riot ahvays formed, the connecting veinlet being sometimes absent. ( Vide 
magnified figure of venation) the receptacles are situated on the converging ajnces of several veinlets.

10. Pleopeltis hemionitidea. (Wall.) Caudex creeping, scaly, furnished with wiry scaly fibrous roots, stipites very short (3-6 
lines long) scaly winged upwards, fronds 6 inches to U foot long, 1-2 inches broad, membranaceous sub-chartaceous, sub-transparent 
very dark shining green, broad lanceolate, gradually acuminated into a fine point at the apex and gradually attenuated at the base, entire 
glabrous, main costa slightly scaly beneath near the base — venation very prominent, costules and veins blackish, the former pinnate nearly 
horizontal, the latter forming about 5 series of sub-quadrate areoles, in which are inconspicuous free veinlets which are either simple or 
forked, but without clavate apices. Sori corapital rather large, forming one series between the costules, and these very irregular in shape 
and size, sub-globose or oblong, or even (by confluence) linear lying transversely with regard to the costa, parallel with the costules. Walt.

My specimens liave only a .single sorus between each of the costtdes situated in the 2nd areole from the costa, they are not pro- 
bahly in full seed. It is allied to " P. membranacea," but differs in having much darker green, more crisp fronds ; the veins form more regu- 
lar areoles than in that species, and both costules and veins are dark and 2u-omi?ient, the venules are very inconspiciious and are not as 
recurved nor are their apices as thickened as in " membranacea."

Sori non-indusiate, globose, cyclose or elliptic, superficial or immersed, buried amongst dense stellate pubescence ; the recejsitacles 
terminal or medial on the excurrent free or irregularly anastomosing veiulets. Veins internal obscure, pinnate prominent or unif(n-m, 
from a central costa venules anastomosing, sometimes transversely parallel, forming parallelogrammoid areoles with excurrent free or 
occasionally connivent or anstomosed veinlets, sometimes uniting in roundish or oblong hexagonal unequal oblique areoles with variously 
directed simple or divaricately forked veinlets, the veins of the fertile fronds when contracted less developed. 
Fronds simple or lobcd, rigid coriaceous opaque, clothed especially beneath with stellate hair-scales or sometimes even lanate ; 
the fertile often contracted, sometimes also more elongated, occasionally fertile at the apex only, and then there contracted, clotlied 
especially beneath with dense stellate pubescence. Sori uni-multi-serial, often crowded and confluent. Khizome creeping often elongated, 
or sometimes short, decumbent. The .species of Niphobolus may be known by having polypodioid sori buried amongst stellate hairs. 
(Moore). 
The venation of Niphobolus is very variable in different sjyecies. Presl. hasjormed 8 genera out of it. 
1. Niphobolus p)orosus. (Wallich.) Caudex creeping, subulato-paleaceous with ferruginous scales, stipites aggregated short scarcely 
any or 3-5 inches long, and then winged or margined to the base, fronds carnoso-coriaceous 6 inches to a foot and more long, \ an inch to 
inch wide, lanceolate or linear-lanceolate or even linear often finely acuminated, the margin quite entire (or rarely spuriously and 
very unequally pinnatifid with remote long and narrow segments) from near the middle gradually attenuated downwards to the caudex, at
