200 Oedeb 1.— KANUNOTJLACE^. 



Order I. RANUNCULACE^. Crowfoots. 

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

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

 distinct, hypogynoua. CoroZia.— Petals 3-15, distinct, hypogynous, sometimes 

 irregular or none. Stamens CX), distinct, hypogynous. Anthers adnate, opening 

 lengthwise. Ovaries 00 or few, simple, distinct, the ceU 1— OO -ovuled. Fruit 

 either dry achenia, or follicles, or baccate, 1 — GO -seeded. Seeds anatropous with a 

 straight, minute embryo in horny albumen. 



lUnstrated in Figs. 10, 24, 132, 143, 162, 241, 242, 233, 291, 294, 867, S86, 415, 453, 236, 288, &o. 

 Genera 48, species about 1000, mostly natives of cool, damp climates, tliose of the tropical 

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



Pbopektibs. Nearly all the genera possess acrid and more or less narcotic properties, some 

 of Ihem being highly prejudicial to animal life. These qualities are dissipated by n boihng heat 

 or by drying, or heightened by spirits and sugar. The species of Helleborus and Acomlium are 

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

 plants.
