PENTSTERIA. A synonym of Torenia (which 

 see). 



PENTZIA (named by Thunberg, in honour of his 

 pupil, Charles John Pentz). ORD. Composites. A. genus 

 comprising ten species of small, hoary, pubescent, glandu- 

 lar, or glabrous, greenhouse shrubs, indigenous to South 

 Africa. Flower-heads yellow, homogamous, corymbose at 

 the tips of the branches, or solitary on long peduncles; 

 achenes glabrous, often glandular ; involucre ovoid or 

 hemispherical ; receptacle flat or convex. Leaves alter- 

 nate, often small, cuneate, toothed, incised or dissected. 

 For culture of P. flabelliformis, probably the only species 

 introduced, see Tanacetum. 

 P. flabelliformis (fan-leaved). fl.-Jieads yellow, disposed in a 



simple corymb. May to August. I. deltoid, serrated at apex, of 



a pale hue. h. 24ft. 1774. (B. M. 212, under name of Tanacetum 



jlabelliforme.) 



PEONY. See Pseonia. 



PEPERIDIUM. A synonym of Reiiealmia (which 

 see). 



PEFEROMIA (from Peperi, Pepper, and omoios, 

 similar ; in allusion to its close relation to that plant). 

 Pepper Elder. Including Micropiper. ORD. Piperacece. A 

 vast genus (nearly 400 species have been described) of 

 mostly stove, annual or perennial, herbaceous plants, 

 usually fleshy and creeping, broadly dispersed over the 

 warmer regions of the globe, but mostly American. 

 Flowers minute, variously disposed, scattered and 

 crowded ; perianth wanting ; stamens two. Leaves 

 alternate, opposite, or verticillate, entire, slightly 

 fleshy, succulent, or slender and membranous, often 

 pellucid-dotted ; stipules none. Peperomias are very 

 interesting, small - growing, ornamental-leaved plants, 

 suitable for culture in small pots ; some of the species 

 that are of trailing habit are also well adapted for hang- 

 ing baskets. Although, properly, the species describu.l 

 below are stove subjects, they may be placed in vases for 

 the temporary decoration of the sitting-room, as their stout, 

 succulent leaves enable them to successfully withstand the 

 change. They should be grown in good, fibrous peat and 



Peperomia continued. 



loam, with the addition of some silver sand. Shade 

 from sunshine throughout the summer is requisite ; but 

 an abundance of light should be allowed in dull weather, 

 and shading dispensed with altogether in winter. Pro- 

 pagated by cuttings, and by seeds when obtainable. 

 Cuttings consisting of short pieces of the shoots, or 

 single joints with a leaf attached, root readily in spring, 

 if inserted in pans of sandy peat ; these should be 

 plunged in a propagating house, but not in a frame : 

 they are liable to damp off if confined. Keep shaded, 

 and only a little moist, until roots are formed. Even 

 when established, Peperomias do not require so much 

 water as many stove subjects. The species described 

 below are grown for the beauty of their foliage. They 

 are perennials except where otherwise specified.
