acuminate, entire or occasionally glandular-toothed, tipped with dark 

 glands, reflexed after anthesis; stamens 20; anthers pale yellow; styles 

 3-5, smrounded at the base by a narrow ring of pale tomentum. Fruif 

 ripening at the end of October, on stout pedicels, in few-fruited clusters,

 calyx very prominent, with a long tube, a deep narrow cavity, and lobes 

 reflexed and deciduous from the ripe fruit; flesh thin, dry and yellow; 

 nutlets usually 4 or 5; bright red-brown, narrowed and acute at the 

 ends,' ridged on the back, with a high doubl}'- grooved ridge, 6-7 mm. 

 long and about 4 mm. wide. 



An arborescent shrub 3-5 mm. high, with numerous erect stems 

 sometimes forming thickets and slender only slightly zigzag branchlets 

 marked by occasional large pale lenticels, dark orange-green when they 

 first appear, soon becoming purplish, bright reddish-brown and lustrous

Bucks county: Dry hillsides near Sellersville, C. D. Fretz (Nos. 145, 

 type!, 127, 136 and 181), May and October, 1901. 



In No. 181 the fruit is described by Dr. Fretz as "greenish or slightly 

 red." The fruit of No. 136. which is 1.1-1.2 cm. in diameter, is de-

 prove distinct.

Leaves broadly ovate, acute, full and rounded, truncate or abruptly 

 cuneate at the wide entire base, slightly doubly serrate above, with 

 straight glandular teeth, and divided into 4 or 5 pairs of short acute 

 lateral lobes, when they unfold yellow-bronze color and sparingly 

 villose on the midribs and veins below, more than half-grown when the 

 flowers open about the 20th of May and then membranaceous and very 

 smooth on the upper and paler on the lower surface, light yellow-green

 with stout yellow midribs and 4 or 5 pairs of slender primary veins 

 arching obliquely to the points of the lobes ; petioles slender, grooved 

 on the upper side, slightly wing-margined at the apex, glandular, with 

 occasional minute glands, and 2-2^ cm. in length; on vigorous shoots 

 leaves ovate-deltoid, truncate to subcordate at the base, more deeply 

 lobed, the sinuses of the lowest lobes often extending more than half 

 way to the midribs, and 5-6 cm. long and broad, with stout conspicu- 

 ously glandular petioles broadly wing-margined below the middle and
