higher nodes. Most n + 2 and n + 3 nodes are reproductive.
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. U

inflorescence on the central axis, and without a regular pattern in the sequ...
