|discussion=<p><i>Crataegus cupressocollina</i> is found through much of the Cypress Hills, where it may be common, and in a restricted area in the Bear's Paw Mountains, Montana. The species is distinctive in its tall, willowy, upright habit, leaf form, relatively long, slender thorns, and two to five year-old orange-brown bark. The flowers differ from those in ser. Douglasianae in their white anthers. The ripe fruit of <i>C. cupressocollina</i> is glabrous and plum red to purple-brown in late August, after which it ripens to a glossy purple-black. The large, pendulous clusters of fruit at once draw attention, as do the reddish tips of the sepals and the soft red-brown of the often nearly eglandular bracteoles when in flower. The colorful expanding bud scales are also rather striking. <i>Crataegus cupressocollina</i> is the first to flower of sympatric species.</p>
