10 A. RE' PENS (Lin. spec. 875.) hairy; leaves pinnate ; leaflets 

 oblong, terminal one sessile ; spikes nearly sessile ; petals 3 times 

 the length of the calyx ; bracteas length of flowers ; stipulas 

 length of the internodes of the stem, and almost covering it; 

 roots creeping ; fruit hispid. I/ . H. Native of Armenia. 

 Like A. Eupatbrla, but the stems are thicker, the spikes more 

 dense, the flowers sessile, and the fruit larger. 



Creeping-rooted Agrimony. Fl.Jul. Aug. Clt. 1737. PI. 2 ft. 



Cult. Plants of easy culture. They will grow in any com- 

 mon soil, and are readily increased by dividing at the root.

 10-12-cleft. Tube of calyx oblong, with a 5-cleft bractless 

 limb. Petals 5. Stamens 5-10. Carpels 2. Styles terminal. 

 Akenia usually solitary from abortion, inclosed in the globose 

 tube of the calyx, thin, membranous. Seed pendulous. An 

 evergreen herb, with interruptedly impari-pinnate leaves ; leaflets 

 dentately serrated, lower ones small, outer ones large. Flowers 

 small, yellow, in fascicles or few-flowered corymbs.

 of Italy and Carniola, in humid places. Agrimonia agrimo-

Cult. See Agrimonia for culture and propagation. 



XX. BRAYE'RA (in honour of Dr. Brayer, the discoverer 

 of the plant). Kunth, in Brayer, not. 8vo. 1824. Paris, diet,

LIN. SYST. Dodecandria, Digynia. Calyx permanent, with a 

 turbinate tube, which is silky on the outside; limb 10-parted, 

 outer segments accessory, large, and oblong ; the 5 inner ones 

 spatulate and shorter ; throat pervious. Petals 5, scale-formed, 

 small, linear, deciduous. Stamens 15-20, nearly equal, shorter 

 than the petals. Carpels 2, free, in the bottom of the calyx, 

 1-2-ovulate. Styles exserted, crowned by subpeltate crenately 

 lobed stigmas. Seed solitary, pendulous. A tree. Peduncles 

 branched, and clothed with soft hairs, flexuous, and bracteate ; 

 flowers 4 together ; bracteas roundish-elliptic. Leaves un- 

 known. 



1 B. ANTHELMI'NTICA (Kunth, 1. c.) T? . F. Native of Abys- 

 sinia, where it is called cotx or cabotz. The flowers of this tree 

 are the most powerful anthelmintic known. Upon the authority 

 of Dr. Brayer 2 or 3 doses of the infusion are sufficient to cure 

 the most obstinate case of taenia. 



Anlhelminlic Brayera. Tree. 



Cult. The tree will possibly thrive well in a mixture of 

 loam and peat, and cuttings will most probably root in sand un- 

 der a hand-glass. 



Tribe II. 



NEURA'DE^E. Calyx 5-cleft (f. 74. a.\ with a short tube, 

 adhering to the ovaries; lobes cut, valvate in aestivation. Petals 

 5 (f. 74. 6.), inserted in the bottom of the calycine lobes. Sta- 

 mens 10. Styles 10. Carpels 10, connected into a 10-celled 

 capsule (f. 74. c.), which is depressed at the apex, and girded 

 by the echinated calyx. Seeds solitary in the cells, bony, ob- 

 liquely pendulous. Embryo curved, with an oblique radicle and 

 oblong cotyledons. Decumbent, frtiticose, tomentose herbs, with 

 sinuately pinnatifid leaves, and small solitary axillary flowers. 

 Seeds germinating in the capsule.
