Nectar is a secretion, typically of flowers, that is composed primarily of carbohydrates, that attracts pollinators such as insects and hummingbirds.
Needle-like leaves are true leaves that are the shape of needles and are typical of pines and firs.
Netted vein leaves are typical of dicot plants. This means that the veins in the leaves are not parallel. They may be pinnately netted or palmately netted. If they are pinnately netted they will have one main midvein and many side branch veins (secondaries). Palmately netted veins will contain several main veins originating from the petiole with many side branch veins.
