Fl, Boem. 3 : 



Perennial from a thick woody rootstock, branched, 

 ascending or erect, pubescent or glabrate. Stipules 

 mostly toothed ; leaves orbicular-reniform, 5-9-lobed, 

 more or less pubescent, the lower slender-petioled, 

 the upper sessile or nearly so, lobes broad, not deep, 

 serrate ; flowers about 2" broad, very numerous in 

 terminal and axillary peduncled often leafy corymbs; 

 pedicels filiform ; calyx glabrous, its lobes usually 

 4, ovate, acutish. 



In grassy places near the coast, Nova Scotia, Cape 

 Breton and eastern Massachusetts. Naturalized from 

 Europe. Duck's-foot. Padelion or lion's-foot. Syndow. 

 Great sanicle. Bear's-foot. Included in our first edi- 

 tion in A. vulgaris L. ; A, glomerulans Buser, and A. 

 filicaulis Buser, are related species of arctic and sub- 

 arctic America and Europe. May-Sept. 



Alchemilla alpina L., found on Miquelon Island, and 

 reported by Pursh (probably erroneously ) from the White 

 and the Green Mountains, a native of alpine and north- 

 ern Europe and Asia, is distinguished from the preced- 

 ing by its 5 oblong silky entire leaflets. 



18. APHANES L. Sp. PI. 123. 1753. 



Small annual herbs, with digitately parted, lobed and toothed leaves, and very small 

 apetalous flowers in axillary cymose clusters. Calyx-tube ellipsoid, contracted at the throat, 

 the lobes 4 or 5; bractlets as many as the calyx-lobes, or none. Petals none. Stamens usu- 

 ally only one, borne opposite one of the calyx-lobes; filament short; anthers introrse. Pistils 

 1-4, usually 2; style basal, slender. Achenes i or 2. [Greek, referring to the insignificant 

 aspect of these plants.] 



A genus of about twenty species, of the north temperate zone. Besides the following, 2 or 3 

 others occur in the western United States. Type species : Aphancs arvensis L, 



I. Aphanes arvensis L. Parsley-Piert, or Field 

 Lady's Mantle. Argentill. Fig. 2263. 



Aphanes arvensis L. Sp. PI. 123. 17S3. 



Alchemilla arvensis Scop. Fl. Carn. Ed. 2, i : 115. 1770. 



Annual, softly pubescent, branching at the base, the branches 

 usually slender, ascending, i'-6' high. Stipules toothed or 

 rarely entire ; leaves very short-petioled, pubescent, fan-shaped, 

 2"-s" long, deeply 3-parted, the lobes cuneate, 2-4-cleft, the 

 segments obtuse or acutish; flowers i"-ii" broad, in sessile 

 axillary clusters partly enclosed by the stipules ; calyx-lobes 

 usually 4, ovate, obtusish or acute. 



In dry fields. District of Columbia to Georgia and Tennessee 

 and in Nova Scotia. Naturalized or adventive from Europe. 

 Breakstone. Parsley-vlix. Parsley-breakstone. Firegrass. Bowel- 

 hivegrass. Colicwort. April-Sept. 



The plant of the southeastern states (A. australis Rydb.) has 

 smaller leaves and flowers than European specimens examined, 

 but does not appear to be specifically distinct from them. 



19. SANGUISORBA [Rupp.] L. Sp. PI. ii6. 1753. 

 Erect, perennial herbs, sometimes decumbent at the base, with alternate odd-pinnate 

 stipulate leaves and small perfect or polygamo-dioecious flowers in dense terminal peduncled 

 spikes. Calyx-tube turbinate, constricted at the throat, angled or winged, persistent, 4-lobed, 

 the lobes petaloid, concave, deciduous. Petals none. Stamens 4, inserted on the throat of 

 the calyx ; filaments filiform, elongated, exserted ; anthers short ; carpel enclosed in the calyx- 

 tube opposite the sepals. Style filiform, terminal; stigmas papillose; ovule suspended. 

 Achene enclosed in the dry angled calyx. Seed pendulous. [Latin, blood-staunching, from 

 its supposed properties.] 



About 10 species, natives of the north temperate zone. In addition to the following, 2 or 3 

 others occur in the western parts of North America. Type species: Sangiiisorba officinalis' 'L.
