200 Obder 1.— RANUNCULACE-^. 



Order I. RANUNCULACE^. Crowfoots. 

 Serbs (or woody climbers) with a colorless, acrid juice. Leaves mostly dividad, 

 exstipulate, with half-clasping petioles. Calyx. — Sepals 3-15, green or petaloid, 

 distinct, hypogynous. (7oroi/a.— Petals 3-15, distinct, hypogynous, sometimes 

 irregular or none. Siamens co, distinct, hypogynous, Anthers adnate, opening 

 lengthwise. Ovaries 00 or few, simple, distinct, the cell 1 — oo -ovuled. Fruit 

 either dry achenia, or folhcles, or baccate, 1— CO -seeded. Seeds anatropous with a 

 straight, minute embryo in horny albumen.

 Genera 43, species about 1000, mostly natives of cool, damp climates, those of the tropical 

 reprions growing only upon the mountains, and in their proper localities abundant. 



PuoPKRTins. Nearly all the ffenora possess acrid and more or less narcotic properties, some 

 of them being highly prejudicial to animal life. These qualities are dissipated by a boiling beat 

 or by drying, or heightened by spirits and sugar. The species of Ilelleborus and Aconitum are 

 highly poisonous, but medicinal when rightly used. This order is rich in ornamental cultivated 

 plants.
