leonardi Barcelona & Pelser
This species was named in honor of Leonard Co, an avid botanist who
devoted much time to the study of the flora of the Sierra Madre
Mountains on Luzon. It was described in the following publication:
Barcelona, J. F, P. B. Pelser, E. Cabutaje, and N. A. Bartolome.
2008. Another new species of Rafflesia
Luzon, Philippines: R. leonardi.
Blumea 53: 223-228.
This species most resembles R.
but it differs in the size of the flower and in its central disk which
is nearly flat on it surface and devoid of prominent processes. Until
recently it was only known from the Cagayan valley in northern Luzon.
As described below, the range has now been extended to
The name R. banaoana was published by Pastor Malabrigo, Jr. (University of the Philippines Los Baños) for a Rafflesia found in the Balbalasang-Balbalan National Park in Kalinga, Luzon:
Malabrigo Jr., P.L. 2010. Rafflesia banaoana (Rafflesiaceae): Another new species from Luzon, Philippines. Asia Life Sciences Supplement 4: 139–146.
This Rafflesia has since been carefully evaluated and found to be conspecific with R. leonardi. The reasoning for this is fully explained in the following publication:
Barcelona, J. F., E. S. Fernando D. L. Nickrent, D. S. Balete, and P. B. Pelser. 2011. An amended description of Rafflesia leonardi
and a revised key to Philippine Rafflesia
(Rafflesiaceae). Phytotaxa 24: 11-18. For a pdf file of this article, click HERE
