Crataegus rivularis

Nutt.

Rosaceae


The taxonomy of Crataegus species has historically been very confused, with over 1,200 different species recognized by some authors in the past. This number has been gradually and very significantly reduced, especially since the publication of several regional studies carried out since the late 1980’s, and current thinking is that the final number could be below 150 distinct species[

]. Many of the genera that were included in this database prior to 2017 will now be treated as synonyms or subspecies, and it is likely that a number of other currently accepted species will also receive that fate once a complete revision of the genus (underway in 2015) has been published.

Many Crataegus species are very variable with regard to fruit size and quality. Seedlings, even if obtained from a good fruiting form, can often be disappointing - though they can also be an improvement on the original form. The most reliable way of obtaining a good fruiting form is by grafting from a known good tree, or obtaining a named cultivar from a reliable source[

Medicinal

Other Uses

The wood of Crataegus species is generally of good quality, though it is often of too small a size to be of much value. It usually has a red-brown heartwood with a thick band of lighter-coloured, usually pale sapwood. The wood is heavy, extremely hard, tough and close-grained. Where wood of suficient diameter is found it is often greatly prized for use in turnery, and has traditionally been used for purposes such as making tool handles, mallets and other small items[

Propagation

Seed - this is best sown as soon as it is ripe in the autumn in a cold frame, some of the seed will germinate in the spring, though most will probably take another year. Stored seed can be very slow and erratic to germinate, it should be warm stratified for 3 months at 15°c and then cold stratified for another 3 months at 4°c[

]. If you are only growing small quantities of plants, it is best to pot up the seedlings as soon as they are large enough to handle and grow them on in individual pots for their first year, planting them out in late spring into nursery beds or their final positions. When growing larger quantities, it might be best to sow them directly outdoors in a seedbed, but with protection from mice and other seed-eating creatures. Grow them on in the seedbed until large enough to plant out, but undercut the roots if they are to be left undisturbed for more than two years.
