Fam. 74. LORANTHACEAE Yadorigi Ka Mistletoe Family 



Shrubs parasitic on shrubs and tree branches; leaves usually opposite, entire, sometimes minute and scalelike, without stipules; 

 flowers bisexual or unisexual, spicate or cymose (sometimes fascicled in axils), usually bracteate and bracteolate, the calyculus 

 (a modified calyx) inserted at base of the ovary, truncate on margin, or absent, the perianth of 1 or 2 whorls with 4-8 free or 

 connate lobes valvate in bud; stamens as many as and opposite the perianth lobes; ovary inferior, 1-locular, 1-ovuled; stigma 

 simple; ovules erect and adnate to the wall of the ovary; fruit a 1-seeded juicy, viscid berry, the seeds adnate to the pericarp, the 



endosperm fleshy, the embryo straight. About 30 genera, with about 1,500 species, mainly in the Tropics, a few in temperate 



regions.
