'''Näivekasvit''' (''Orobanchaceae'') on 25 sukua ja niissä noin 200 lajia sisältävä ''loisia tai puoliloisia. Heimo on kosmopoliittinen ja sitä esiintyy Pohjois-Amerikassa sekä osassa Uutta Seelantia. Trooppisessa Afrikassa ja Amerikassa esiintyy vain muutama laji.

Loisivat lajit, kuten Luounais- ja Etelä-Suomessa harvinaisena kasvava haustorioita'', jota tunkeutuvat isäntäkasvin solukkoon ja imevät sieltä ravinteita.

Suomessa esiintyviä näivekasvisukuja ovat:
*''Bartsia'' &ndash; punakot (puoliloisia)
*''Euphrasia'' &ndash; silmäruohot (puoliloisia)
*''Lathraea'' &ndash; suomukat (loisia)
*''Melampyrum'' &ndash; maitikat (puoliloisia)
*''Odontites'' &ndash; sänkiöt (puoliloisia)
*''Pedicularis'' &ndash; kuusiot (puoliloisia)
*''Rhinanthus'' &ndash; laukut (puoliloisia)

'''Orobanchaceae''', or the '''broomrape''' family, is a family of order ''sensu lato''. Together they are a monophyletic group, forming a distinct family.

This is a cosmopolitan family, found mainly in temperate Eurasia, North America, South America, parts of Australia, New Zealand and tropical Africa.

Except one genera, (''Lindenbergia''), all members of this family are holoannual or perennial herbs or shrubs growing on the leaves have been reduced to somewhat fleshy, sessile scales that are lanceolate, oblong to ovate.  The hemiparasitic species (transferred from Scrophulariaceae) are capable of photosynthesis, and may be facultative or obligate parasites.

Parasitic plants are attached to their host by means of haustoria, which transfer nutrients from the host to the parasite.  Only the hemiparasitic species possess an additional extensive root system. In most holoparasitic species there is a swollen mass of short, bulky roots or one big swollen haustorial organ, which may be simple or composite. 

The hermaphroditic flowers are bilaterally symmetrical and grow either in  calyx is formed by 2-5 united sepals. There are five united, bilabiate corolla. The upper lip is two-lobed, the lower lip is three-lobed. There are two long and two short pollinated by insects or birds (e.g. hummingbirds, as in ''Castilleja'').

The capsule with many very minute endospermic seeds. These are dispersed by the wind over long distances, which increases their chance of find a new host.

This family has tremendous economic importance because of the damage caused by genera such as ''Striga''.
