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
Largest known prime number the progression of the largest known prime number in ascending order. Here M = 2 − 1 is the Mersenne number with exponent "n". The longest record-holder known was M = 524,287, which was the largest known prime for 144 years. No records are known before 1456. GIMPS found the fourteen latest records (all of them Mersenne primes) on ordinary computers operated by participants around the world. A list of the 5,000 largest known primes is maintained by Chris K. Caldwell, of which the twenty largest are listed below. Largest known prime number The largest known prime number () is
