The genus Cycas (Cycadaceae) in the Philippines

Abstract

The genus Cycas is reviewed for The Philippines. Ten species are enumerated, with five described as new (Cycas saxatilis, C. aenigma, C. vespertilio, C. nitida and C. lacrimans). C. wadei, C. curranii and C. saxatilis are placed in the new Section Wadeae. Lectotypes are chosen for Cycas circinalis subsp. riuminiana var. curranii forma graminea J.Schust. and Cycas circinalis subsp. riuminiana var. curranii forma maritima J.Schust. The species are placed within an infrageneric classification previously outlined. Distribution of all taxa is mapped, conservation status is discussed and a key to species provided. Previous recordings of C. circinalis and C. rumphii from The Philippines are discussed. © 2008 Royal Botanic Gardens and Domain Trust.
