Conifers  - Conifers are gymnosperms such as pine, hemlock and spruce and they do not have vessels.  They have tracheids.  There are two types of conifer wood: resinous and non-resinous.  Conifer wood is made up mostly of tracheids and fiber tracheids, from a volume basis.  Conifers have tracheids with pits.  There are four basic types of wood, ring porous, diffuse porous, (simi-diffuse), conifer without resign ducts and conifers with resign ducts.  And then there are palms.
