  8. C. Order Asparagales Iridaceae- iris family

  9. pollinia stigma anther cap stigma column P(3+3) A1-3 G(3) inferior with gynostemium C. Order Asparagales Orchidaceae- orchid family 800/20,000 cosmopolitan/tropical diversity 1) strongly mycotropic habit in terrestrial species 2) diverse in tropics and subtropics; many epiphytic 3) numerous tiny seeds with minute mostly undifferentiated embryo and no endosperm 4) bilateral corolla with labellum = lower lip (simple, sac or spur) [labellum is actually the upper petal but because of resupination, a 180° twist, it appears as the lower one] 6) pollinia - waxy or mealy masses under anther cap 7) gynostemium- stigma + styles + androecium = column 8) pollination involves many elaborate mechanisms 9) five subfamilies
