Examples of "pinnatifid"
The fern has a 20–30 cm high trunk. Its 2- or 3-
fronds are 0.5–1 m long and 30–45 cm wide.
Hairs, where present, are unbranched and branched, from whitish to brown in color. The leaf blades range from
in cutting, bearing free veins which usually end in hydathodes on the upper surface of the leaf. Sori are borne beneath pinnae or lobes, sometimes slightly sunken into the leaf tissue, usually in two rows but rarely in one. The sori are circular to elliptic in shape; the sporangia lack hairs.
The fern has a wiry, creeping rhizome, with adpressed, reddish brown hairs. Its 3- or 4-
fronds combine a 2–7 cm long stipe with a triangular-ovate lamina 4–6 cm long and 2–5 cm wide.
"Prionosciadium bellii" is a biennial herb up to tall. Leaves are up to long,
with tapering lanceolate segments. Flowers are reddish-purple or greenish-yellow. Fruits are oval, up to long.
"Achillea abrotanoides" can reach a height of about . The stem is subglabrous to tomentose. The leaves are grey-green, hairy,
or bipinnatifid and alternate, about long. This plant blooms from June to August, with many-stellate white flowers.
"Achillea clavennae" can reach a height of about . The leaves are silvery silky-hairy,
, cut into some lobes, alternate, about long. This plant blooms from June to August, producing many loose clusters.
"Rhaponticum" species are perennial herbaceous plants with simple, rarely branched stems. The leaves are simple to
. The inflorescence is on the apex of the stem. The fruit is an achene with a hairy pappus.
It is a large species with deeply
foliage fronds. The nest fronds resemble the leaves of oaks, hence the common name. The sori are either scattered or arranged in two regular rows in between the secondary veins.
The leaves are petiolate with a length of . The basal leaves are oblong, oval, lanceolate, lyrate,
to dentate, long, wide. The cauline leaves are much reduced and are short petiolate to sessile but not auriculate-clasping.
"Polypodium virginianum" is a small rhizomatous fern with narrow leaves 8–40 cm long and 3–6 cm wide borne on smooth, scaleless petioles (3–15 cm). Leaves are evergreen, oblong and
with acuminate tips.
The simple leaves are alternate or sometimes whorled. They have petioles and are not enclosed by a sheath. The leaves are usually lobed or
(i.e. consisting of several not entirely separate leaflets), or much divided. There are no stipules.
The prostrate shrub typically grows to in height and has non-glaucous branchlets. It has simple linear flat leaves that have an
shape and are long and wide.
Perennial with woody stock. Leaves in a basal rosette,
with rounded lobes; margins subspinose. Scape up to 80 cm, with a few small bracts. Inflorescence a dense corymb of up to 20 heads. Heads densely tomentose.
The plant is high. Radical leaves are × , oblanceolate, Iyrate-
, acute, upper surface puberulous, lower surface glabrous; petiole long; cauline leaves: lower ones similar to radical leaves or acuminate; upper ones sessile, lanceolate, acuminate-caudate.
Leaves alternate and variable in shape, simple or
, the leaf margins wavy. 12 to 20 cm long. Leaf venation is clearly seen above and below the leaf. Leaves are characteristic and easily identified as part of the Protea family.
"Woodsia neomexicana" has stems that are largely obscured by the persistent bases of scales and dead leaf bases. Leaves are up to 30 cm long, pinnate with
pinnules (leaflets) with scattered hairs.
"Asplenium × wherryi" is a small, evergreen fern. The fronds are monomorphic, showing little or no difference between sterile and fertile fronds. The dark-colored stipe (the stem below the leaf blade) is up to long, while the rachis (the central axis of the leaf) is green. The leaf blades are lance-shaped, cut into ten to sixteen pairs of pinnae. The leaf blades are bipinnate at the base (with pinnae fully cut into pinnules), becoming pinnate-
(with lobed pinnae) in the middle of the blade and merely
(cut only to lobes) near the tip. The spores are abortive and the species is presumed to be triploid.
Members of the family have the following characteristics, being distinguished by having strongly dimorphic fronds, with the fertile fronds different from the sterile fronds. The rhizomes are long- to short-creeping to ascending, and sometimes stoloniferous (Matteuccia and Onocleopsis). The leaves are strongly dimorphic and the petioles have two vascular bundles uniting distally into a gutter-shape. The blades are
. The veins are free or anastomosing, lacking included veinlets. The spores are reniform, brownish to green. The sori are enclosed (sometimes tightly) by reflexed laminar margins, also with membranous, often fugacious true indusia.
"Brassica napus" grows to 100 cm high with lower leaves
and glaucous and the upper leaves clasping the stem. The flowers are yellow and about 17 mm across. "B. napus" differs from "B. nigra", but can be distinguished by the upper leaves which do not clasp the stem, from "B. rapa" by its smaller petals which are less than 13 mm across.
The sterile and fertile fronds of "Onoclea sensibilis" are quite different from other ferns. The bright, yellow-green sterile fronds are deeply
and are typically borne at intervals along a creeping rhizome. They grow to about long, with a long, smooth stipe.
