species, of which only two kinds were yet known, and those of very limited 

 geographical range, witli simple (undivided) fronds, and from which it is abun- 

 dantly distinguished in form, texture, and fructification, was discovered by my 

 valued correspondent, a great lover of Ferns, the Rev. C. S. P. Parish, Chaplain 

 at Moulmein. It inhabits, as far as yet known, only one spot on the said moun- 

 tain, a large mass of rock, about 200 feet lielow the summit, very difficult of access, 

 and in some lime, the result of the continued filtering and dropping of the 

 rains from a cave above. There it is " tolerably abundant over the sjjace of a 

 few feet, as Woodsia hyperhorea grows on the eastern precipice of Snowdon, in 

 company with Cheilanthes farinosa and other interesting Ferns, but nowhere 

 else has it been seen at all." 



The Adiantum Philippense, L., which I have, following all preceding botanists, 

 placed in tliis group (see p. 3 of this volume), is figured by Petiver, the original 

 authority for the plant as pinnate, and I have little doubt but it may be safely 

 referred to J. lunulatum, Sw. 



After Pellaea rotundifolia, j). 136 of this Volume, insert — 

 7*. Pelleea Bridyesii, Hook. ; caudex short thick creeping 

 entangled bearing the fronds from the apex clothed with 

 copious subulate ciliated scales, fronds 4-6 inches long ob- 

 long-lanceolate firm coriaceous very glaucous pinnated, pinnee 

 almost invariably opposite (15-21) broad-elliptical cordate 

 short-petiolate very obtuse opaque, the two halves when dry 

 reflected upon each other, veins sunk obsolete, the margin 

 entire with a very slender but not incurved white cartilaginous 

 edge, sori linear on the veins confluent and forming a 

 broad line parallel and a little distance from the margin, in- 

 volucre none (and no inflection of the margin upon the sori), 

 stipites and rachis dark purple-brown glossy. (Tab. CXLII. 

 B. in Vol. III.) 



Hab. Mountains, interior of California, Bridges. Sierra Nevada, Wm. Lobb. — 

 This is a very remarkable Fern, with much in the habit and in the nature of fructi- 

 fication of Pellaa (Platyloma, /. S'm.) paradoxa, falcata, and rotundifolia, of a sin- 

 gularly glaucous hue, and quite destitute of involucre. In short, as far as the sori 

 are concerned, one can hardly see why it should not range %vith Gymnogramme, 

 especially with Gymn. (Pterizoma, Fe'e) reniformis. In the dried state every 

 pinna has the two halves bent back, so as to meet behind {dorso conduplicata). 

 A few of the lowest ones are usually sterile, and nearly orbicular. The species 

 is the more interesting as coming from a country so widely remote from the 

 locality of the allied species above alluded to. It has indeed fewer traces of 

 a real involucre, or indusiura, than those, and tends to confirm the views of Mr. 

 Brown respecting his Adiantum paradoxum (our Pellcea paradoua), namely, that 

 it is an Adiantum with a continuous sorus, but that sorus not inflexed, as in 

 most of the true Adianta, but patent, as in the species now under consideration. 

 Nevertheless, specimens of the closely-allied Pelleea paradoxa and PelUvafalcata 

 do exhibit, in an immature state, the presence of an involucre, though narrow 

 and eventuallv obsolete.
