The Rose Family is fairly diverse, encompassing not only roses, brambles and sweet briars, but many of the 'berries' such as strawberry, raspberry, loganberry, etc. But it also includes meadowsweet,, avens, agrimony, burnets, lady's-mantles, pirri-pirri-burs and the cinquefoils and tormentils.

The latter form the Tormentil Complex, being hybrids between Tormentils and Cinquefoils. There are only four known hybrids, and only one of those possesses a common name, Hybrid Cinquefoil.



[ALCHEMILLA] Lady's-mantles

Dandelions (as well as Brambles (Rubus, Hawkweeds (Hieracium) all have hundreds of species. They are all apomictic (or agamospermic - asexual reproduction via seeds), capable of the production of viable seeds without self-fertilization or cross-fertilization and are entirely female in origin. Plants growing from these seeds are clones. This process results in a wide spectrum of hybrid microspecies, most looking very similar. All or most species of Dandelion are hybrids which reproduce asexually - only a handful reproduce by sexual means. Hawthorns (Cratageous), Rowans & Whitebeams (Sorbus), Meadow-grasses (Poa) and Lady's-mantles (Alchemilla) are also apomictic with dozens of very similar hybrid species.

OTHER POTENTILLAS
There are a number of other Tormentils and Cinqufoils with no known hybrids. These are listed here: Hoary Cinquefoil, Shrubby Cinquefoil, Grey Cinquefoil, Russian Cinquefoil, Mountain Cinquefoil, Ternate-Leaved Cinquefoil, Marsh Cinquefoil, Sulphur Cinquefoil, Brook Cinquefoil and Rock Cinquefoil. Most of these are unlikely to get any other entries in this tome, for, with the exception of one or two, they must appear very similar to anyone but an expert.

There are two hybrids which cannot be placed in the above chart because one or more of their parents are not native to the UK, namely:
S. × multiflora × thunbergii (Spiraea × arguta) [Bridal Spray/Bridal Wreath]
S. cantoniensis × trilobata (Spiraea × vanhouttei) [Bridal Wreath]
Both are popular cultivars planted as garden plants, and both sometimes share the same common name 'Bridal Wreath'. Both have panicles of large white flowers.

Spiraea × arguta is a cross between S. × multiflora (which is itself a hybrid between S. crenata and S. hypericifolia) and S. thunbergii, hence the two '×'s in its expanded 'latin' name.
