 ebeneoiis glossy decickiously scaly, fronds about a s])an long 

 deltoidly lanceolate glabrous on both sides and perfectly free 

 Ironi ])o\vdery substance beneath pinnate the ajiex deeply 

 l)innati(id and acuminate, pinnic u])))er ones lanceolate pin- 

 natifid, the rest broader and bipinnatifid, lowest pair very 

 broad at the base with their lowest inferior segments for pin- 

 nules) much longer than the rest, the margin crenated some- 

 times in the barren portions ciliated, involucres brown scariose 

 reniform close but generally distinct sometimes confluent and 

 then less ciliated but lobed and jagged. (Tab. LXXVIII. B.) 



Hab. Simla, Ludj/ Dalhousie, Mr. Edyetvorth. Mokargavi, Kuniaon 

 4500 feet of elevation, 3Iessrs. Strachey and Winterhottom. — Did I possess 

 only a solitary specimen of this, or were the specimens any of them mixed 

 up with Ch.farinosa, 1 should have been disposed to consider it a powder- 

 less variety of that species : but there is not a trace upon any of my speci- 

 mens of that pulverulent substance seen more or less copiously upon all 

 ixue farinosa, and these have been found by three different persons at diffe- 

 rent periods, yet only in two localities. I venture therefore to ofler it as dis- 

 tinct. Its fronds are of a thin membranaceous texture, turning pale olive- 

 brown in drying, and the fructifications present nearly the same variations 

 in the involucre that we see in Ch. farinosa. It naturally ranks with that 

 species, though here artificially placed in another section. 



7. Ch. pteroides, Svv. ; caudex thick creeping scaly, stipes 

 1 — 2 feet long and as well as the rachises (which are woolly at 

 their axils with slender scales) stout ebeneous glossy, frond 

 ample glabrous 1 — Ig- foot long tripinnate, pinnae and pin- 

 nules distant, the latter pctiolulate often an inch long cordate 

 elliptical obtuse crenate opaque brown when dry, involucres 

 copious contiguous yet distinct subrotund membranous brown 

 extending over the whole margin. — (Tab. CI. A.) Siv. Si/n.

Hab. Cape of Good Hope, abundant, in rocky mountainous places, from 

 1000 — 3000 feel of elevation. Summit of Mount Gcde, Java, Blume. — We 

 have here a Fern very distinct from any other Cheihmthes, so distinct, that 

 it needs no elaborate description for distinguishing it ; with the true in- 

 volucres, indeed, of that genus, but with the habit altogether of certain 

 species of Pteris or Allosorus common at the Cape. The plant has conse- 

 quently vacillated between Adiantum and Pteris and Cassebeera and Chei- 

 lanthes, according to the views of respective authors. — An authentic speci- 

 men of the Java plant, from Dr. Blume, shows that that is identical witli 

 the Cape ]>lant, as are the Ch. mulli/ida and hirla of Java with those 

 respective plants of South Africa,
