glossy green, dentate or serrate, especially near the apex, fading 

 in autumn with tones of yellow and brown : flowers which open 

 about the middle of April, solitary or in twos or threes : pedicels 

 pubescent, becoming glabrous or with a few hairs persistent : 

 3 mm -i cm long, bearing one or more narrow, caducous bractlets : 

 calyx obconic, sparingly pubescent, the divisions 3. 5— 5 mm long, 

 serrate or glandular-serrate, reflexed after anthesis : petals nearly 

 orbicular, 5-6 mm in diameter, the claw at the base relatively short 

 and broad : stamens normally 20, 3-4 mm long : styles 3-5, sur- 

 rounded at the base with pale hairs : fruit pyriform, 9-1 2 mm 

 high, 7-gmm w ide, the cavity about 4 mm wide, surrounded by the 

 persistent calyx lobes and remnants of the stamens : nutlets 3-5, 

 hard and bony, about j mm long, 3~4 mm measured dorso-ventrally, 

 the lateral faces nearly plane and the back grooved and ridged. 



Cratceg-us ?nunda, another form of the " flava group," with small, glossy 

 leaves and in aspect somewhat similar to C. uniflora, 1. c, is closely associated 

 with C. invicta above proposed, from which it differs in the less pubescent foli- 

 age and pedicels, more sharply cut and scarcely lobed leaves, less spiny branches 

 and rather larger fruit. 



The type material is preserved in the Biltmore Herbarium. 



Crataegus vulsa n. sp. 



A tree 4-6 111 tall with a trunk i-2 dm in diameter branching 

 i-3 m above the ground, the ascending or spreading branches 

 forming an oval, usually compact symmetrical head : or often a 

 large shrub with one or several stems : bark of the trunk or stems 

 gray tinged with brown, thin, fissured and scaly ; of the branches 

 smooth, the growth of the season glabrous, bright reddish-brown : 

 spines stout, either straight or slightly curved, 2.5-4 cm long, or 

 frequently of much greater size and compound on the trunk and 

 larger branches, chestnut-brown or gray : leaves ovate, oval or 

 round-ovate, the blades i.5-7 cm long, i-6 cm broad, glabrous or 

 with a few hairs along the veins and in their axils, sharply and 

 irregularly serrate and incisely lobed, acute at the apex, either 

 rounded or abruptly narrowed at the base and extending into 

 margined petioles 5 m m_ 2 .^cm long ; they are thin to firm in texture, 

 bright green, fading with decided tones of yellow and brown : 

 flowers produced in glabrous, compound, 3-10-flowered corymbs, 

 the lower branches arising from the axils of leaves, appearing in
