Subdivision of Arachis hypogaea L. holds two subspecies: A. hypogaea subsp. hypogaea and A. hypogaea subsp. fastigiata. Subspecies hypogaea has a central axis that never bears inflorescence and has laterals where vegetative branches alternate regularly with reproductive branches. The inflorescence is simple, seeds show dormancy and plants are late maturing (120 to 150 days depending on temperature and crop density). In general, these types branch profusely and have a runner or spreading bunch habit. In runners (prostrate) the stems trails over the ground, while in spreading bunch, the main stem is erect, while branches trails on the ground. The US market types Virginia and Virginia Runner and the distinct variety hirsuta belong to this group.
