Lecture 21- pollination + rearing children: no food fo(cid:396) polli(cid:374)ato(cid:396)s= pi(cid:374)k lady"s slippe(cid:396). They have fake stammens and pseudopollen= the lure. There is a hinged petal, winged coffin with sex organs. Clamping saddlebags of pollen: white water lily= when they open up, they attract flies like crazy. As the night goes on the flower closes and the bugs are trapped. When it opens first as a female (cid:894)stig(cid:373)a (cid:271)elo(cid:449)(cid:895) a(cid:374)d s(cid:449)eet li(cid:395)uid att(cid:396)a(cid:272)ts i(cid:374)se(cid:272)ts. Whe(cid:374) it ope(cid:374)s it"s a (cid:373)ale and so the bugs take the pollen from the stemma with them. They are more attracted by the female open ones so they take the pollen there. Laurens have bashing stamens that pin down the insect under pressure and if you touch them they go up: bunchberry gro(cid:449)s i(cid:374) shady ha(cid:271)itat a(cid:374)d has a lot of lea(cid:448)es.
