4-6-8 or 10 inches long rarely exceeding i an inch wide, 

 from a broad dccurrent base cbMigato-oblong acute or ob- 

 tusely acuminate, tiie margin slightly tliickened, venation evi- 

 dent often slightly prominent and distinct (except the vcinlets) 

 on the under side, costules or rather primary veins horizontal 

 flexuose forming a series of large costal soriferous areoles and 

 a second lesser series, secondary veins forming a network of 

 small areoles including free veinlets, sori large copious sub- 

 oval sunk into a hemispherical cavity (forming a pustule or 

 pouch on the upper side, the mouth with a distinct elevated 

 rim) arranged in a single series on nearly the whole length of 

 every segment and close to the costa. — Bl. Fil. Jav. p. 159.

 the P. nigrescens of Bhime ; but surely no two plants can be more distinct. 

 Bhime calls this, "Filix iiiagnifica, 4-pedalis vel saepius orgyalis et ultra:" — the 

 texture, form, etc., are quite difFereiit in the two. The cavities for the reception 

 of the sori do not form the perfect sac or i)ouch which we see in P. nigrescfiiis ; 

 but, in an old state, when the sori have fallen away, there is a perfectly hemi- 

 spherical cavity with a raised edge, as complete as if it were turned by an instru- 

 ment and as smooth within as a tea-cup. 



369. p. (Phymatodes) nigrescens, Bl. ; caudex stout creep- 

 ing partially clothed with ovate appressed at length decidu- 

 ous scales, stipites 1-H foot long, fronds membraneous (sub- 

 carnose when recent) blackish-green when dry 2-3 feet long 

 oblong acuminate cuneato-decurrent at the base deeply pin- 

 natifid with obtuse sinuses, segments 3-23 10-12 inches long 

 1-2 inches broad (terminal one the largest) oblongo-lanceolate 

 very finely acuminate entire, venation very distinct, primary 

 veins rather than costules forming large angled costal areoles 

 soriferous in the centre, the secondary veins form a copious 

 network of small areoles which include close-placed free 

 veinlets, sori large sunk into a deep cavity or pouch which is 

 very prominent on the ujiper side arranged in a single series 

 much nearer the costa than the margin. — Bl. Fil. Jav. p. 101.
