The coiled “fiddlehead” of fern leaves are rooled-up leaf buds. Fiddleheads are formed by a pattern of growth called
circinate vernation, as shown in this Blechnum fern.
Fern sporangia . Most ferns have sporangia aggregated into clusters, called sori, on the undersides of the leaves.
In some ferns, such as the marginal wood fern (Dryopteris marginalis), each sorus is covered by a flap of leaf tissue
called an indusium.
Grows upon another plant (such as tree) non-parasitically or
sometimes upon other objects ( such as a building or telegraph
wire). Derives its moisture and nutrients from the air and rain and
sometimes from debris accumulating around it.
Equisetum (Equisitophyta)
1.Its stem is the dominant photosynthetic organ of the plant body.
2.The conspicuous feature of the stem is the series of joints formed by a
whorl of small leaves.
3.The leaves are fused along most of the length of the stem, but their
brown tips give the appearance of a collar around the stem at the joints.
Strobili, or cones, are aggregations of closely packed sporangium-bearing
branches or leaves.
Gemmae cup
This is a type of thallose liverwort. During sexual
reproduction, spores produced in the capsule germinate to
form independent male and female gametophytes. Marchantia
also reproduces asexually by fragmentation and gemmae.
Pinophyta (common name: conifers)
 The leaves are scale-like.
 No fascicles.
Nephenthes sp.
Derive some or most of their nutrients (but not
energy) from trapping and consuming animals or
protozoan, typically insects and other arthropod.
Carnivorous plants appear to adapt and grow in
places where the soil is low in nutrients.
