16. NEVITJSIA A. Gray. 



Shrus, with spreading terete branches. Leaves alternate : blades membranous, simple, 

 doubly serrate : stipules slender. Flowers perfect, white, solitary or in open clusters. Hy- 

 panthium bractless, flattish. Sepals 5, petal-like, imbricated, spreading, incised-serrate, 

 persistent. Petals wanting. Stamens numerous, persistent, in several series : filaments 

 glabrous. Pistils 2-4, sessile. Style nearly terminal, stigmatose on the inner side. Ovules 

 solitary in each cavity, pendulous. Achenes drupe-like, with a thin fleshy epicarp and a 

 crustaceous endocarp. 



1. Neviusia Alabamnsis A. Gray. A branching shrub 6-15 dm. tall, with minutely 

 pubescent young foliage. Leaves numerous ; blades ovate to ovate-lanceolate, 2-7 cm. 

 long, acute or acuminate, doubly serrate, rounded or subcordate at the base, sparingly 

 pubescent on both sides or glabrous in age ; petioles 3-8 mm. long : pedicels slender, 

 1.5-2 cm. long: hypanthium minutely pubescent without: sepals leaf-like, obovate or 

 oblong-cuneate, 8-12 mm. long, sharply serrate above the middle : petals wanting: filaments 

 filiform-clavate, longer than the sepals. 



On cliffs, near Tuscaloosa and on Sand Mountain, Alabama. Summer. 



17. ALCHEMI'LLA L. 



Annual or perennial caulescent herbs. Leaves alternate : blades digitately lobed or 

 compound, petioled : stipules a dilation of the base of the petiole. Flowers perfect, small, 

 in open or congested cymes. Hypanthium urn-shaped. Sepals 4-5, valvate, augmented by 

 4-5 bractlets. Disk often almost closing the throat of the hypanthium. Petals wanting. 

 Stamens 1-4 : filaments very short, distinct. Pistils 1-4, sessile or short-stalked : style 

 lateral or basal, glabrous : stigma capitate. Ovule solitary, ascending. Achenes 1-4, 

 included. 



1. Alchemilla arv6nsis ( L. ) Scop. Annual, strigillose or somewhat villous. Stems 

 simple and erect or usually branched at the base, the branches ascending, 2-15 mm. long : 

 leaf-blades 3-parted, 4-10 mm. long, the segments cuneate, 2-4-cleft, the lobes obtuse : 

 stipules leaf-like, cleft or rarely nearly entire : flowers in sessile axillary clusters : calyx 

 greenish, 2-3 mm. broad : sepals shorter than the hypanthium, ovate, obtuse or obtusish. 



In sandy fields, Virginia to Tennessee, North Carolina and middle Georgia. Naturalized from 

 Europe. Also on the Pacific slope and in Nova Scotia. Early spring. 



18. AGRIMONIA L. 1 



Perennial pubescent and often glandular herbs, with erect stems. Roots sometimes 

 tuberous. Leaves alternate, with leaf-like stipules : blades unequally pinnate, the rachis 

 often bearing interposed small leaflets between the larger ones. Flowers perfect, in wand- 

 like racemes. Hypanthium persistent, campanulate or turbinate, more or less distinctly 

 grooved, armed above with hooked bristles. Sepals 5, converging. Petals yellow, 5, 

 longer than the sepals. Stamens 5-15, in one series : filaments distinct. Pistils 2, sessile, 

 included: style slender: stigmas 2-lobed. Ovule solitary, pendulous. Achenes 1 or 2, 

 included in the hardened accrescent hypanthium. Seed pendulous. AGRIMONY. 



Leaflets incised-toothed, the teeth few, salient or recurved. 1. A. incisa. 



Leaflets serrate, dentate or crenulate, the teeth several or many. 



Lower surfaces of the leaves, and racemes softly and closely pubescent. 



Roots not tuberous-thickened : leaves mostly with over 11 narrow leaflets. 2. A. parviflora. 



Roots tuberous-thickened : leaves mostly with less than 9 broader leaflets. 



Leaflets 3-5. 3. A.pumila. 



Leaflets 5-9 or rarely more. 4. A. mollis. 



Lower surfaces of the leaves, and racemes glabrous or with loosely spreading hairs. 

 Roots tuberous-thickened : fruit 2.5-3.5 mm. high, hemispheric, with few ascend- 

 ing bristles. 5. A. striata. 

 Roots not tuberous-thickened : fruit 6-12 mm. high, turbinate, with many radiat- 

 ing bristles. 6. A. hirsute. 



1. Agrimonia incisa T. & G. Stems shaggy-villous below the inflorescence, 3-11 

 dm. tall, simple or branching above, the branches ascending: leaves 5-16 cm. long; 

 stipules incised-laciniate ; leaflets 7-11 or fewer in the upper leaves, the blades firm, 

 cuneate, obovate or oblong-obovate, coarsely incised, the teeth salient or recurved, a main 

 pair and 1 or 2 smaller pairs of small leaflets on the rachis in each interval : racemes in-
