+Laburnocytisus adamii anagyroides" + "Chamaecytisus purpureus". +"Laburnocytisus adamii" is a legume, a member of the pea family Faboideae (or Papilionaceae, formerly Leguminosae). Only one cultivar, 'Adamii' (formally designated as +"Laburnocytisus" 'Adamii'), is known to have arisen from this graft. Most of the tree's branches resemble the laburnum in their foliage, which has three leaflets (3-palmate) and 3–6 cm long, yet also with dense clusters of broom-like shoots, also with three leaflets, but only 1 cm long and a darker green. It flowers in late spring or early summer; some branches have long (20–30 cm) racemes of yellow laburnum flowers, while others produce
Colour centre the recognition of shapes, motion, and colour. V1 has multiple areas that are colour-sensitive, which indicates that colour processing is not limited to one area. According to a paper by Dr Robert Shapley, V1 has an important role in colour perception. fMRI experimental results showed that V1 has two kinds of colour sensitive neurons: single-opponent and double-opponent cells. These cells are integral in the opponent process of interpreting colour signals. Single-opponent neurons respond to large areas of colour. This is advantageous for recognizing large colour scenes and atmospheres. In comparison, double opponent cells respond to patterns, textures, and colour boundaries.
