Gen. 32. Ceratopteeis, Brong.
Sori placed on two or three veins which ru n down tlie frond longitudinally',
and are nearly parallel both with the edge and midrib. Caps, scattered on
the receptacles, sessile, subglobose, with a ring which is either complete,
or more or less p a rtia l or obsolete. Invol. formed of the reflexed margin of the
frond, those of the two sides meeting against the midrib. A very anomalous
genus, regarded hy some as a distinct suborder and placed by others in Polypodieae.

when young, bi- or tripinnate, with narrow linear segm. when mature, fertile ones
bi- or tripinnate ; ult. segm. podlike.—Hk . Sp. 2. p . 236.
Hab. Throughout the Tropics in quiet waters; Mexico and W. Indies southward to
Brazil ; Punjaub southward to Tropical Australia, Madagascar, Angola, West Tropical
Africa,—Parkeria pteroides, Hk. Gr. Ic. t. 97, is the form without a ring to the capsule.
Gen. 33. L omaría, Willd.
Sori linear, continuous, parallel with the midrib and occupying the whole or
nearly the whole of the space between it and the edge. Invol. membranous,
formed of the revolute edge of the frond. Fronds dimorphous, usually once
pinnatifid or pinnate, rarely simple or bipinnate. Veins free, except casually in one
species. A considerable genus, closely connected with Blechnum, most o f the species o f
which resemble one another closely in habit and cutting, which has its head-quarters
in the South Temperate Zone, with outliers all over the world. T a b . IV. f. 33.

of the distance from the top, narrowed very g radually downwards, the point
acuminate, the margin cartilaginous and wavy ; texture coriaceous, veins inconspicuous
; fertile f r . as long h u t only 4 in. br. ; sori occupying the whole space
between the midrib and margin.—Hk. S p . 8. p. .3. F . E x . t. 49. L. Cumingiana,

on each side, which are often 6-9 in. 1., n early 1 in. br., and suddenly decurrent
a t the base, the fertile pinnæ often numerous on each side, erecto-patent, 6 in. 1.,

Hab. a, S. Australia, Van Diemen’s Land, and Philippines.—¡3, Neilgherries and
Ceylon eastward and southward to Fiji and New Zealand.—Tbe two supposed species
were at first believed—Patersoni to be always simple, and elongata to be always pinnate ;
but the Australian one has now been traced into a pinnate form, and tbe Polynesian
into a simple form in the fertile state, and in each case I cannot find any character to
distinguish these from the other supposed species. As in most of others, the fronds are
occasionally in part sterile and in part fertile. The pinnæ are fewer and more distant
from one another than in any of the species that follow, and their decurrent base is
broader and more conspicuous.
