I don't know about 'treillis' rivers, but the Loire river seems to me to be dendritic (in the sense of arborescent)
Dendritic pattern
Dendritic because the rivers cross a gradual slope over one basic type of rock.
The Amazon River is an example of dendritic drainage, which resembles the branching pattern of tree roots. Dendritic drainage patterns are common in areas with uniform rock structure and slope, where rivers and streams flow in multiple directions.
the Nile river has a dendritic pattern because it has a tree like drainage pattern created if rivers cross a gradual slope over one basic type of rock.
The dendritic pattern develops where the river channel follows the slope of the terrain. The stream with its tributaries resembles the braches of a tree , thus the name dendritic. It also flows underneath a rock that is the same hardness.
There are seven major rivers in India and well over 100 small rivers in India.
Narmada River
Rivers between India and the rest of Asia are Indus river, Ganges river and Brahmaputra river.
