A shrub about 1 metre high, with slender nearly straight branchlets, dull red-brown and marked by pale lenticels when they 

 first appear, becoming dark purple at the end of their first season, and armed with numerous very slender straight spmes from 

 2 to 3 centimetres in length. Flowers the end of May. Fruit ripens early in October.

Crataegus steixata, n. sp. (Intricate.) 



Glabrous with the exception of the hairs on the upper surface of the young leaves. Leaves oblong-ovate acuminate abruptly 

 or gradually narrowed and concave-cuneate at the base, finely often doubly serrate with .taught glandular teeth, and divided 

 into four or five pairs of acuminate spreading lateral lobes ; about half-grown when the flowers open and then thin, yellow-green 

 and slightly hairy above and glabrous below, and at maturity thick, yellow-green, and lustrous on the upper surface, paler on the 

 lower surface, from 3.5 to 4 centimetres long and about 2.5 centimetres wide, with slender midribs and thin primary veins ex- 

 tending obliquely to the points of the lobes ; petioles slender, slightly wing-margined at the apex, from 1.5 to 2.5 centimetres in 

 length ; leaves on vigorous shoots broadly ovate, acute, abruptly cuneate at the wide base, thicker, more coarsely serrate, more 

 deeply lobed, from 5 to 6 centimetres long and from 5 to 5.5 centimetres wide, with stout wing-margined glandular petioles. 

 Flowers cup-shaped, from 1.6 to 1.8 centimetres in diameter, on short slender pedicels, in compact from three- to five-flowered 

 corymbs; calyx-tube broadly obconic, the lobes separated by wide sinuses, slender, acuminate, entire or minutely glandular- 

 dentate near the middle ; stamens ten ; anthers creamy white ; styles from three to five. Fruit on slender erect pedicels, oval or 

 subglobose, dull reddish green, from 1.1 to 1.3 centimetres in diameter ; calyx prominent, with a long tube, a wide deep cavity 

 pointed in the bottom, and reflexed and appressed lobes ; flesh thin, hard and dry; nutlets from three to five, thin and rounded 

 at the ends, broader at the apex than at the base, rounded and slightly grooved on the back, from 5.5 to 6 millimetres long and 

 3.5 millimetres wide, the small hypostyle extending rather less than half the length of the nutlet. 



A shrub, from 2 to 2.5 metres high, with erect branches forming a compact head and slender only slightly zigzag branchlets 

 light orange-brown and marked by pale lenticels when they first appear, becoming light chestnut-brown and very lustrous in their 

 first season, and armed with stout straight spines from 2 to 3 centimetres in length. Flowers the first week of June. Fruit 

 ripens the end of September.

Crataegus shirleyensis, n. sp. (Anomalce.) 



Leaves ovate to oval or obovate, acuminate, cuneate or rounded at the entire base, sharply often doubly serrate with straight 

 glandular teeth, and slightly divided above the middle into small acuminate lobes pointing forward ; when they unfold slightly 

 tinged with red and covered above by soft white hairs and glabrous below, nearly half-grown when the flowers open and then 

 still hairy above, and at maturity thin, blue-green and smooth or scabrate on the upper surface, paler on the lower surface, from 

 4.5 to 5 centimetres long and from 2.5 to 4 centimetres wide, with slender midribs, and thin primary veins extending obliquely to 

 the points of the lobes ; petioles slender, slightly wing-margined at the apex, pubescent on the upper side early in the season, 

 soon glabrous, glandular with occasional deciduous glands, from 1.6 to 2 centimetres in length ; leaves on vigorous shoots abruptly 

 pointed at the apex, gradually narrowed and rounded at the base, more deeply lobed and often from 5.5 to 6 centimetres long 

 and 4 centimetres wide. Flowers 1.5 centimetres in diameter, on slender pedicels densely covered with long white matted hairs, 

 in small lax from five- to eleven-flowered hairy corymbs ; calyx-tube narrowly obconic, densely villose, the lobes gradually nar- 

 rowed from broad bases, acuminate, coarsely glandular serrate near the middle, glabrous on the outer surface, villose on the 

 inner surface, reflexed after anthesis ; stamens twenty; anthers pink ; styles three or four, surrounded at the base by a narrow 

 ring of pale tomentum. Fruit on long slender slightly villose pedicels in drooping clusters, subglobose to short-oblong, orange- 

 red, about 1 centimetre in diameter; calyx little enlarged, with a wide shallow cavity broad in the bottom, and closely appressed 

 lobes often deciduous from the ripe fruit ; flesh thin, dry and mealy; nutlets three or four, gradually narrowed and rounded at the 

 ends, broader at the apex than at the base, only slightly ridged on the back, from 5 to 6 millimetres long and 3 millimetres wide, 

 with obscure ventral depressions, the broad prominent hypostyle extending to below the middle of the nutlet. 



A shrub, from 2 to 3 metres high, with stout slightly zigzag glabrous branchlets light orange-brown when they first appear, 

 light chestnut-brown and lustrous at the end of their first season and dull gray-brown the following year, and armed with numer- 

 ous stout straight lustrous ultimately gray spines, from 2.5 to 3.5 centimetres in length. Flowers the end of May. Fruit ripens 

 from the middle to the end of September. 



Massachusetts : roadsides, Shirley, Middlesex County, Evelyn F. Thayer, May 22, 1904, May 18 and 20, and September 17, 

 1906 (No. 3, type). 



This plant is entirely unlike any of the other species of eastern New England, and I refer it with considerable doubt to the 

 Anomahe Group on account of the shape of the leaves on vigorous shoots, which resemble those of the other plants of this group, 

 rather than on account of the slight depressions sometimes found on the ventral faces of the nutlets, as these are often entirely
