HYBRID CHARTS
This shows the hybrid charts of families of plants. [The hybrid charts themselves are embedded within the  Family Album pages, but that is of no concern]. For added convenience, those Family Album pages which have hybrid charts (not all of them do because some Families do not appear to have hybrids found in the wild) are all listed individually here.

The hybrid chart, example above, takes the form of a n × n square array, where the possible parents are both listed on the two royal-blue axes, x-axis and-axis. If a hybrid between two parents on the x- and y-axes exists, then the corresponding square within the body of the chart is highlighted green. Those squares without hybrids are in dark blue. The black square are on the negative-sloping diagonal; a hybrid cannot exist between two identical parents. Note that the diagram is symmetrical and that each hybrid appears twice, on either side of the black diagonal.

Where the hybrids have (English) names then these are shown in preference to the latin name, which will be of the form : first name × second name

In the (active) example above, clicking on non-empty squares results in the popping out of external pages from the BSBI (Botanical Society of the British Isles) website. Clicking on either a parent or a hybrid will result in a BSBI map of the distribution of the plant so called, where you will also see further details purporting to its name.

On the other hand, clicking on the key square (top left) will result in a list of ALL species with that first name, regardless of whether they hybridise. This is extremely useful in seeing all the possible species belonging to that particular sub-group, many of which will not yet be listed in this, the Wild Flower Finder website.
