What type of rock has little to no grain development and has a vesicular texture?

Obsidian - volcanic glass - is one type of rock that would fit that description. It is glassy (grainless) and frequently has pockets of trapped air bubbles in it.

Is pumice has no grain?
Pumice is so fine grained, it actually doesn't have a grain--because it is a natural volcanic glass. The rough texture is caused by the vesicular nature of the rock--trapped pockets of gas bubbles with sharp glassy edges.
What else does rock texture include besides grain size and arrangement?
Grain shape.
What is obsidians grain shape?
Pure obsidian actually has a glassy texture (grain), with no discernible crystalline structure.

How does texture affect grain size in rock?
It doesn't. The grain size effects the texture. If a rock has a small grain size, it will have a smooth texture. If the grain size is large, such as pebbles, the texture will be rough. For example, siltstone is one of the smoothest rocks because it contains silt particles, which are .0004cm to .006cm. Conglomerate though contains various particles including cobbles and boulders, which are from 10cm to 100cm.
