Topologically, an H tree has properties similar to those of a dendroid. A locally connected dendroid is called a dendrite. The capillitium is highly branched with brown dendroid elements. Dictyonema is a genus of dendroid graptolites in the order Dendroidea. The dendroid graptolites survived until the Carboniferous period. The plants are densely covered with dendroid stellate hairs and additionally with simple, unbranched hairs. Stems are generally frondose, but may rarely be dendroid. Most of the dendritic or bushy/fan-shaped organisms are classified as dendroid graptolites (order Dendroidea). Dendroid is malware that affects Android OS and targets the mobile platform.
