vdns iu pinnate groups, 2-4 veinlets on a side.—H k . Sp. 6. p . 6.
Hab. West Indies and Guatemala to Brazil.—A very variable plant. In seedlings tbe
veins are often simple or once forked, and quite free, P. reptans of authors is the loose
straggling, and P. asplenioides the more erect larger form. P. asterothrix, Hk., is probably
another form, with broad deeply-lobed pinnæ and 4-6 veinlets on a side, and a
more villose rachis ; and G. gracilis, Moore, apparently also belongs here.

f r . 3-4 ft. 1., 1 ft. or more br. ; pinnæ very numerous, 8-10 in. 1., I J - I J in. br.,

both sides naked ; vdnlets prominent, 20-26 on a side ; sori close to the main
vein.—H k . Sp. 6. p. 7.
Hab. Society Isles and Fiji.—G. longissima, Brack., Hk. I. c., from Tahiti, is probably
a larger form of the same plant ; but in,our specimens from the author, whioh have pinnæ
18 in. 1., the rachis is muricated. G. glandulifera. Brack,, from Samoa, which we have
not seen, appears to be closely allied ; and we have a similar plant from the New
Hebrides from Mr. C. Moore.

scaly ; f r . lJ -2 ft. 1., 8-12 in. br. ; pinnæ 4-6 in. 1., |-1 in. br., cut about
halfway down into blunt, falcate, sliglitly crenated lobes about 2 lin. br. ; lower
pinnæ gradually reduced ; texture firm-herbaceous ; rachis and both sides
naked ; veinlets 6-8 on a side ; sori in rows near the midrib.—H k . Sp. 5. p . 7.
G. Forsteri, Moore.
Hab. New Zealand.—Very near P. tetragonum, from which it differs principally by
the lower pinnæ being gradually reduced.
79. P . (Goniopt.) unitum, H k . ; St. 1 - lJ ft. 1., slender, naked ; f r . 2-3 ft. 1.,
1 ft. br. ; pinnæ 4-6 in. 1., j - J in. hr., the apex acuminate, the edge b lu n tly

the main veins.—H k . Sp. 6. p . 6.

the forma of P. tetragonum.

villose ; f r . 1-3 ft. 1., 1 ft. or more br. ;
J-1 in. Vr., the lowest narrowed a t the base and sometimes stalked, cut from a
falcate ; veinlets 12-16 on a side.—H k . Sp. 6.
Hab. Cuba and Panama, southward to Brazil and Peru.—Judging from tbe figures
quoted, this is P . androgynum of Lamarck ; and if so, that name has priority. I t varies
greatly in the breadth of the pinnæ and depth of the lobes. A full account of the forms
will be found iu Fde’s Ferns of the Antilles ; and our a apparently includes his tenera,
leptocladia, pyramidata, Féei, tetragona (five varieties), quadrangularis, Guadalupensis,
and hastata. Our ? is placed by Mettenius iu his latest publication in Aspidmm.
