Species, genera & family pages of‎‎‎ Loranthaceae are now with images. I request you to pl. go through & point out mistakes, if any. I hope this will aid in identifications in future. If anybody can send images of other species of this family (for incorporation in the website), if any, or can identify unidentified images, it will be really nice.
