Answer 2

These plants are parasites:
Cassytha, Laurel Dodder (Lauraceae-Laurel Family)
Cuscuta, Dodder (Convolvulaceae-Morning Glory Family)
Orobanchaceae (Broomrape Family)
Striga (Witchweeds-Broomrape Family)
Orobanche (Broomrapes-Broomrape Family)
Sandalwood Parasites
Loranthaceae (Showy Mistletoe Family)
Santalaceae (Sandalwood Family)
Viscaceae (Christmas Mistletoe Family)

"Two main types of parasitic plants can be distinguished: stem parasites and root parasites. Stem parasites occur in several families, and pathogenic members include some mistletoes (see below) and dodder (Cuscuta). Root parasites are more common and are found in diverse taxonomic groups. Some of the most economically important root pathogens are in the Orobanchaceae. Parasitic plants may also be classified as holoparasites, hemiparasites, obligate parasites, or facultative parasites (Figure 3). Facultative parasites contain chlorophyll and can be grown to maturity without hosts. Obligate parasites, on the other hand, require a host for maturation. Hemiparasites contain chlorophyll when mature (hence are photosynthetic) and obtain water, with its dissolved nutrients, by connecting to the host xylem via the haustorium. Holoparasites lack chlorophyll (and are thus nonphotosynthetic) and must rely totally on the contents of the xylem and the phloem of the host. All holoparasites are obligate parasites. Although these definitions imply absolute and discrete categories, some parasitic plants are intermediate between the hemi- and holoparasitic condition, e.g. Cuscuta (dodder)."

Besides illustrations, there's also a table included on the above site which lists the parasitic plant, its host, & where they are located.

Good Luck! Hope this is helpful.

Answer 3

Both sites are informative, but the one that ANGEL has as her source has a lot more information.
Very interesting.
Sorry, but I do not have a source for you.
