Canoe Camp, 150 ft. 
A very distinct plant in its foliage, which resembles that of some of the dwarf 
Pandanus, such as P. parvus, Ridl. The broad leaves with a spiny edge are remarkable 
in a Mapania, as are the large involucral leaves surrounding the capitulum. The only 
specimen is, unfortunately, in young flower.
