Pinus johannis
Introduction
The validity of this species is in question. For example, Farjon and Styles (1997) consider it a variety of P. cembroides (subspecies cembroides var. bicolor). On the other hand, it is considered a valid species by Price et al. (1998), and forms a separate lineage from P. cembroides in chloroplast DNA trees (Gernandt et al. 2003).
