Descriptions of the Species. 
9 1 
41. P. robusta. Frond ovate oblong, two inches long, one inch broad, 
coriaceous, 3-pinnate ; lobes of pinnules not at the base but attached 
half-way up or more. 
42. P. pectiniformis. Frond lanceolate, pinnate, rigid, coriaceous, more 
or less clothed with adpressed woolly scales, pinnules linear. 
43. P. lancifolia. Frond lanceolate, glabrous, 2 -pinnate ; pinnules ovate 
or deltoid, with a narrow base ; indusium very broad. Texture herb- 
aceous. 
44. P. consobrina. Frond 3-to 4-pinnate, deltoid, about as long as 
broad, more than four inches each way. Stipe and rachis brown. 
45. P. Boivini Frond twice as long as broad, 3-pinnate or 
46. P. Namaquensis 2-pinnate, stem and rachis brown, except in P. 
47. P. involuta - leucomelas. A very closely connected group, 
48. P. hastata having no arbitrary characters distinguishing 
49. P. leucomelas J them. 
50. P. calomelanos. Frond 2-to 3-pinnate, deltoid ; stipe, rachis, and 
petioles, black and shining ; pinnules stalked, cordate, or deltoid, 
glabrous. 
51. P. Burkeana. Veins anastomosing (the only species in which they 
are so). Fronds pinnate or 2-pinnate. 
38. Pell/ea auriculata. Link. 
Plate XXXII. Nat. size. 
Crown tufted, paleaceous, with lanceolate rusty brown scales, 
or sometimes almost without scales. Frond herbaceous, lanceo- 
late, simply pinnate, or sometimes 2-pinnatifid, six to nine inches 
long, half to one inch broad, with a short brown-black soft naked 
or slightly scaly stipe, and a polished brown naked green-margined 
rachis. Pinnae about eighteen pairs, not regularly opposite, sessile 
or very shortly stalked, bluntly pointed, ovate or cordate-ovate, or 
sometimes with one or more lobes at the base, hastate, or cut 
nearly to the mid-rib ; barren pinnae more rounded than others. 
Indusium nearly a line wide, similar in texture to the frond. 
Crenate along its edge and the margin of the frond is also crenate- 
wrinkled. The crenations on the indusium appear almost like 
the separate indusia of Cheilanthes, but are only vein wrinkles, 
and not distinct lobes. 
This species is very various in cutting, and seems to include 
both Adiantum auriculatum, and Pteris confluens of Thunberg,
