Herbs, or shrubby plants, often with a milky juice. Leaves 

 alternate, without stipules. Flowers often showy, axillary and 

 terminal. Calyx-tube adherent to the ovary ; limb 5-cleft, per-

 celled, many-seeded capsule. 



An order embracing many splendid ornamental species, and distinguished 

 by acrid and narcotic properties. These are especially developed in the Lobe-

 Anthers 2-celled. Ovary 2 5-celled. Style furnished with 

 collecting hairs. Capsule crowned with the persistent calyx- 

 tube, opening with loculicidal dehiscence, many-seeded.

phylos), and Pyrola, fig. 21, and sometimes narcotic and poifonouf". as In the
