Does this have an explanation? Hybrid? Mutation? Convolvulus characteristic?
- Do 4-cotyledons germinants mean something specific?

The seedlings of, say, Morning glory have 2 cotyledons, but they are very deeply lobed, each one has 2 fingers. Still, they are distinctly one (i.e. clearly just 2 coty's)
Maybe your particular species has them so deeply lobed that they are now subdivided into 2 leaflets.
Flowering plants, called angiosperms, have embryos with one or two cotyledons. Those with one cotyledon are known as monocotyledons or monocots. Monocots include bananas, pineapples, and corn. Most bear leaves with parallel veins and flower parts in multiples of three. Angiosperms with two cotyledons are called dicotyledons or dicots. They produce leaves with a netlike pattern of veins and flower parts in multiples of four or five. Beans, squashes, and tomatoes are common dicots. Gymnosperms (nonflowering, woody plants) have embryos with two or more cotyledons, depending on the type of plant. Such needleleaf, cone-bearing trees as pines and hemlocks are gymnosperms.
Cotyledons have various functions. In some seeds, such as those of cereal grains, the cotyledon absorbs stored food from the endosperm (food storage tissue) of the seed. In other seeds, including those of peas and beans, the stored food is first absorbed by the developing embryo and then deposited in the fleshy cotyledons. When the seed of a pea sprouts, the cotyledons remain underground. In beans, however, the cotyledons appear above the ground and function briefly in photosynthesis .
Other cotyledons, such as those of morning-glories, resemble regular leaves in appearance and function.
2 have germinated from 10 that I sowed and both had 2 pairs of cotyledons (or 4 cots. if your prefer). I feel the coincidence is too big that both are mutations.
I will follow the plant and document it.
