deciduous from the ripe fruit; flesh thin and yellow; nutlets usually 

 3, full and rounded at the base, rounded at the narrow apex, ridged 

 on the back, with a high narrow ridge, about 7 mm. long and 4 mm. 

 wide. 



A tree-like shrub sometimes 3 m. high, with stout erect stems covered 

 with ashy-gray bark, and stout slightly zigzag branchlets marked by 

 small pale lenticels, dark red-brown when they first appear, light red- 

 brown and very lustrous during their first season, becoming dark gray- 

 brown the following year, and occasionally armed with short stout 

 nearly straight bright red-brown shining spines.

 Rare. 



This species is named for Isaac Shoemaker Moyer, A.M., M.D. 

 (1838-1898), long a practicing physician at Quakertown in Bucks 

 county, deeply interested in botany, ornithology and entomology, 

 and the author of a flora of Bucks county published in 1876 in 

 General W. W. H. Davis' History of Bucks County. 

 12. Crataegus saturata n. sp. 



Leaves oblong-ovate, acuminate, cuneate or rounded at the base, 

 finely doubly serrate, with straight glandular teeth, and divided into 

 4 or 5 pairs of short acuminate lateral lobes, slightly tinged with red 

 when they unfold, nearly half-grown when the flowers open about the 

 20th of May and then membranaceous, glabrous wath the exception of 

 a few short scattered hairs toward the base on the upper side of the 

 midribs and glabrous below, and at maturity thin but rather rigid in 

 texture, glabrous, very smooth and dark blue-green on the upper and 

 pale on the lower surface, 4-6 cm. long and 3-3.5 cm. wide, with thin 

 midribs, and very slender primary veins extending obliquely to the 

 points of the lobes; petioles slender, slightly wing-margined at the 

 apex, sparingly glandular, with often persistent glands, 2-2.5 cm. 

 in length; stipules linear, lanceolate to linear-lanceolate, glandular, 

 with minute long-stalked glands, fading rose color, mostly deciduous 

 before the flowers open ; leaves on vigorous shoots thicker, much more 

 deeply lobed, with broad acute lobes, and often 6 cm. long and nearly 

 as wide. Flowers about 1.4 cm. in diameter, on short slender glabrous 

 pedicels, in usually 4-6 very compact corymbs, with linear acute gland- 

 ular bracts and bractlets; calyx-tube broadly obconic, the lobes wide, 

 acuminate, usually entire, glandular, with stipitate glands, and reflexed 

 after anthesis; stamens 5-7; anthers rose color; styles 3 or 4, sur- 

 rounded at the base by a narrow ring of pale tomentum. Fruit ripening
