| The drag-induced bending moments and stresses increased basipetally toward the base of the tree. |
| The hairs are oriented acropetally, while in the proximal part of the sac they grow basipetally, i.e., oriented toward the lemma-sac interface. |
| For example, young ponderosa pine needles first exhibit a lightening in color which turns light brown to reddish-brown at the tip and progresses basipetally along the needle. |
| In this context, Sell suggested that the enrichment axes flower basipetally while the inflorescence branches develop acropetally. |
