The degree of rarity of members of the Apiaceae (Umbrellifeae) family in the Fergana valley

When studying each rare species of plant, the study of them on the basis of a certain order, that is, into a certain group, increases the efficiency. For example: a distributed area is a common, similar to a living environment, or a factor thatmultiplies in a similar way or, on the contrary, affects a decrease, etc. In this article, the generality of the families of plants was taken as a unit. The reasons for this are several: in plants belonging to the same family, basically the living environment, the distribution area and even the factor that affects the decrease will also be similar.
