Wilkin 



A tree 3-5™ high with long horizontal 

 branches forming a flattened crown, trunk armed with numerous long, 

 often compound, thorns. Bark on the scaly trunk gray, that of the 

 branches smoother and lighter. Twigs glabrous, slender, olive or 

 russet, armed with many stout 4-6''" long dark gray thorns. Leaves 

 spatulate, 5-9 ^'" long including the very short petiole, 2^ '"' wide, acute 

 or obtuse at apex, gradually tapering into the short grooved winged 

 petiole, glabrous, dark green above, much paler beneath, thin for the 

 'I g^oup, the 3-5 pairs of prominent veins impressed above, obtusely 



serrate above the middle, seldom lobed. Flowers about 14"^™ wide, in 

 large compound many-flowered glabrous corymbs, appearing the first 

 week of June; calyx obconic, glabrous, the narrow entire lobes reflexed 

 after anthesis; stamens about 10, anthers pink; styles 2-^. Fruit in 

 large compound clusters on drooping pedicels, oblong, le-iS"'"" long, 

 fnll and rounded at the ends, dull red, capped by the reflexed calyx 

 lobes, ripening early in October, persistent until late in winter; flesh 

 firm, bitterish ; seeds generally 2, sometimes 3, deeply grooved on the 

 rounded back. 



The species above proposed was collected in both flower and fruit at 

 Mansfield, O., by E. Wilkinson, who has permitted me to associate his 

 name with the plant; collected also in fruit by IV. W. Ashe. It differs from 

 the typical cockspur thorn in the longer, thinner, and more pointed leaves, 

 and deeply impressed veins. It is more closely related to C Canybi Sarg, 

 (Box. Gaz. 31:3. igoi) which it much resembles in the shape of the leaves, 

 and the impressed veins, and from which it is separated by having longer, 

 stouter thorns, thicker foliage, smaller fruit, and fewer differently colored 

 anthers, 



Crataegus habilis, n. sp.— A tree 4-6" high with numerous spread- 

 ing and ascending branches forming an oval crown. Trunk sparingly 

 armed, its bark scaly, trunk dark gray or brown, that of the branches 

 smoother and lighter- Twigs ascendmg, glabrous, thick, soft, oliva- 

 ceous or chestnut-brown, sparingly armed with stout chestnut thorns 

 3-4"^ long. Leaves thin but firm, dark green above, paler beneath, 

 the blades broadly oval, 4-5 "™ long, 3-4 '"^ wide, abruptly acute at apex, 

 J'ounded or truncate at base, with 4-6 pairs of shallow notches, sharply 

 but finely serrate, glabrous below on unfolding, pubescent above with 

 short hairs, soon glabrous, fading to lemon yellow and falling late in 

 September or early in October; petiole about 2"*° long, slender, nearly 

 terete, grooved above, at first pubescent, soon glabrous. Flowers 

 16-^20^"^ wide, borne in small 3-4'"^ wide, nearly simple pubescent 

 cymes, cup-shaped, appearing the second w^eek in May when the leaves
