IIEMIOXITIS. 191 



length as their stipites very coriaceous thick rigid glossy obo- 

 vatc cuneato-attenuate at the base entire the margin slightly 

 recurved and thickened, costa and venation internal very ob- 

 scure, veins anastomosing forming oblique oblong areoles not 

 extending to the margin with no free included veinlets ; fer- 

 tile fronds 4-5 inches long 1 .7 line wide thick coriaceous sub- 

 semitcrete, sori sunk in a deep furrow on each side the tbick- 

 ened but obscure costa. — Hook. Ic. PI. t. 99G {or Cent, of 

 Ferns, t. 96). Schizolepton, Moore, Ind. Fit. p. 344. 



Ilab. Borneo, near Sarawak, Thos. Lohb. — A most remarkable and very rare 

 Fern with quite the liabit of Drymoglossttm, but with very coriaceous rather than 

 fleshy fronds, no free veinlets in the areoles, and with sori sunk in a groove. 

 Surely those who sanction Tanitis lanceolata being placed in Drymoglossnm may 

 well allow this to remain there. 



11. Hemionitis, Linn. 



(Hook. Gen. Fil. tab. LXXIV. B, Dictyocline, Moore. 

 Anetium, SpUtg. Acrostichnm, Linn., in part. Antropbyum, 

 in part, Fee.) 



Sori linear, elongated, mostly superficial, uniformly ana- 

 stomosing always on the veins and sometimes sparsely scat- 

 tered in the areoles (Anetium, SpUtg.). Veins cojMously 

 anastomosing and soriferous. — Fronds simple, pahnato-pinna- 

 tifid or pinnate. 



§ 1. Sori confined to the veins. Hemionitis. — Sp. 1-4. 



1. H. lanceolata, Hook.; caudex stout as a man's thumb 

 in one of my specimens, ascending scarcely repent, its apex 

 paleaceous with sul)ulate small scales, stipites subfasciculate 

 8-10 inches long bright castaneous very glossy stout, fronds 

 firm-coriaceous submembranaceous opaque 6-10 inches long 

 lj-2^ inches wide below the middle, simple broad-lanceolate 

 acuminate narrowly marginate obtuse or cuneato-attenuate 

 at the base, costate, costa very prominent beneath, venation 

 uniform, costules none, areoles oblong obliquely patent hexa- 

 gonal smaller towards the margin, sori copious anastomosing 

 like the veins. — Hook. Id Cent, of Ferns, t. 55. 



Hal). Fiji l%\mA%, Milne, Seemann, n. 716.— A verj' handsome species which 

 has some resemblance to a simple-fronded form of Grammitis ( Dictyor/ramme) 

 pinnata {Hemionitis elongata, Brackenridgo), which indeed bears simple fronds 

 when young, but such are always linear-lanceolate, destitute of sori, and small ia 

 comparison to tliese fronds, which abound in fructification ; and the venation is 

 quite different in the two.
