inserted on all parts of it.Two-faced, bifaria, springing only on the two opposite sides of the

branch.Scattered, spnrsa, growing without certain order.

Crowded, covferta, numerous almost hiding the whole branch or stem.Imbricated, imiricata, covering half of each other,fascicled, fasciculata, many from the same point at the joint of the

branches.Two-fold, three-fold, five-fold, &c, Una, terna, quina, ©V. according

to the number at the joints of the branches.Confluent, covflt/enfta, cohering together at the base.Approximated, approximata, coming very near each other.Remote, remota, distant from each other'.Opposite, opposita, placed cross-wise by pairs.Decussated, decussata, so disposed oppositely, that the branchf s, as
