Prominent (diminuitive = prominulous)

Title

Prominent (diminuitive = prominulous)

Definition

Raised above the surface; e.g., the veins of a leaf or a seed.

Notes

The differences among salient, prominent, prominulous, plane, and submerged are based on the degree of elevation, e.g., between the top of a vein and the surface of the organ of which it is a part. These features grade into one another but generally speaking a salient vein is one that projects 0.5 to several millimeters above the surface, a prominent vein is one that is distinct and raises between 0.1 and 0.4 mm above the surface, and a prominulous vein is one that is raised so little that it is only perceived when a finger nail is run along the blade at a right angle across it. If nothing blocks the fingernail, the vein is plane and if a depression is perceived it is impressed. If a vein is not seen, it is said to be submerged in the tissue. In neotropical Lecthidaceae, this terminology is mostly applied to the the veins of leaves and seeds.
