Rafflesia consueloae studied. The species is the smallest of all "Rafflesia", measuring an average diameter of when fully expanded. The disk surface of newly opened flowers of "R. consueloae" is described to as distinctly cream-white and usually without processes. It is reported that "R. consueloae" has bisexual flowers, the third species after "R. baletei" and "R. verrucosato" to be described as such in the Philippines, but it has not been established whether both sexes of each flower are functional. "Rafflesia consueloae"'s flowers do not exhibit the distinct odor found in "R. arnoldii" (nicknamed the "corpse flower") and most species of "Rafflesia", with
Rafflesia the largest "single" flower of any flowering plant, at least in terms of weight. "Amorphophallus titanum" has the largest "unbranched" inflorescence, while the talipot palm ("Corypha umbraculifera") forms the largest "branched" inflorescence, containing thousands of flowers; the talipot is monocarpic, meaning the individual plants die after flowering. Comparison of mitochondrial DNA (mtDNA) sequences of "Rafflesia" with other angiosperm mtDNA indicated this parasite evolved from photosynthetic plants of the order Malpighiales. Another study from that same year confirmed this result using both mtDNA and nuclear DNA sequences, and showed the three other groups traditionally classified in Rafflesiaceae were unrelated. A more
