needle-shaped
Like a pine
Needle-shaped describes something long, slender, and pointed like a sewing needle.
The term appears most often in botany for leaves like those of pines and firs: needle-shaped leaves help conifers conserve water.
It also describes crystals, cells, or other objects with this elongated, tapering form.
