PETUNIA 



PEUMUS

inches apart each way; but on fertile soil, and particu- 

 larly with the larger-growing forms, the distance may 

 be as much as 15 to 18 inches. Young petunia plants are 

 very susceptible to frost. It is well to pull out some of 

 the least desirable plants as they grow and begin to 

 crowd. The stronger common strains of petunia are 

 likely to self-sow or volunteer (come up themselves in 

 the spring from seed). Fancy kinds are sometimes 

 propagated by cuttings or slips from plants carried over 

 winter, after the manner of geraniums. The best double 

 strains particularly are often perpetuated by cuttings. 

 There are no special insects or diseases attacking the 

 petunia. 



Winter bloom is easy to secure from petunias under 

 glass. Best, or at least quickest, results are secured 

 from cuttings; these may be taken from good shoots in 

 late September or early October from selected outdoor 

 plants, and bloom should be secured by February 1. 

 If plants are grown from seeds, the sowing should take 

 place in late summer, for seedlings grow slowly in the 

 short days of fall and winter; the seedlings should be 

 handled in pots. Sometimes old plants that are not 

 spent are lifted in the fall and cut back, and the new 

 growth will give good winter bloom. Petunias under 

 glass require cool treatment, a night temperature of 45 

 to 50 suiting them well. A somewhat warmer treat- 

 ment than that given carnations may be expected to 

 produce satisfactory results. 



axillaris, BSP. (P. nyctaqiniflbra, Juss. Nicotiana 

 axillaris, Lam.). Fig. 2879. LARGE WHITE PETUNIA. 

 Tall and relatively stout, usually growing erect: Ivs. 

 large and rather thick, oval-oblong, upper ones nearly 

 or quite sessile and the lower ones narrowed into a dis- 

 tinct petiole: fls. dull white, long-tubed (the tube 3 or 

 4 times the length of the calyx), fragrant at evening. 

 Argentina. B.M. 2552. Frequently seen in old gar- 

 dens, and also escaped. 



violacea, Lindl. VIOLET-FLOWERED PETUNIA. Sts. 

 slender: Ivs. oval or ovate, sessile or very short-stalked: 

 fls. smaller, broad-tubed (the tube twice or less the 



length of the 

 linear calyx- 

 lobes), rose-red 

 or violet, the 

 limb relatively 

 short. Argen- 

 tina. B.R.1626.

 Common petu- 

 nia, probably a 

 hybrid deriva- 

 tive of the two 

 E receding. For.

 173 (asP.nycta- 

 giniflara viola- 

 cea). B.M. 3556. This type is remarkably variable, but 

 it differs markedly from either parent: from P. axillaris 

 in its broader tube and many colors; from P. violacea in 

 its longer tube, wider limb, and many colors; from both 

 in its much larger and multiform fls. and more stocky 

 growth. In some of the strains, the fl. is very broad 

 and open, measuring 4 or 5 in. across. There are types 



with the fls. deeply fringed; others with star-like mark- 

 ings radiating from the throat and extending nearly or 

 quite to the margin of the limb; others with full double 

 fls. The colors range from white to deep red-purple, 

 and variously striped and barred. There are forms of 

 very dwarf and compact habit. L H. B.

PEUCEDANUM (ancient Greek 

 name). Umbettiferas. There are many 

 views as to the limits of the genus 

 Peucedanum, which is equivalent to 

 saying that it has no natural limits. 

 Bentham & Hooker made it a most 

 complex group, comprising about one 

 hundred Old World and New World 

 species, and including such genera as Petrqselinum, 

 Anethum, Imperatoria, Pqlycyrtus, Tommasinia, Pasti- 

 naca, Tiedmannia, Lomatium. Coulter & Rose, Ameri- 

 can monographers ("Monograph of the North Ameri- 

 can Umbelliferae," United States Department of Agri- 

 culture, 1900), remove the American species and 

 accept Rafinesque's genus Lomatium, where these 

 species may be found (page 1903, Vol. IV). The par- 

 snip has been included in this genus as P. sotivum, 

 Benth. & Hook., but is here kept distinct under Pas- 

 tinaca. Various species of Peucedanum may be trans- 

 ferred to grounds in Europe, or the countries where 

 they grow, but they are not" known as horticultural 

 subjects. 



PEUMUS (Chilean name). Syn., Boldda, Boldea, 

 Rinzia. Monimidcex. The Chilean boldo, a small tree 

 of considerable economic interest. 



Evergreen tree or large shrub of 1 species, P. B61dus, 

 Molina (P. frdgrans, Pers. Ruizia frdgrans, Ruiz & Pav. 

 Boldda frdgrans, Gay): dicecipus: male fls. with 10-12 

 perianth-lobes, overlapping in 2-3 series, the outer 

 ones herbaceous or membranous, the inner ones more 

 petal-like; stamens numerous; female fls. smaller, the 

 lobes more unequal, after anthesis circumscissile above 

 the disk-bearing base and deciduous: drupes 2-5 or 

 rarely solitary, stipitate on the receptacle; seeds pendu- 

 lous: the tree attains a height of 20 ft., with Ivs. oppo- 

 site, leathery, very rough and warty, ovate or ovate- 

 elliptic, short-petioled, obtuse. Chile. B.R. 31:57. 

 The tree has exceedingly hard wood, which is used for 

 making many kinds of implements; it also makes a 

 charcoal said to be prized by smiths above all others. 

 The bark is used in tanning and dyeing. The Ivs. are 

 used in medicine. The frs. are edible; they are small 

 berries, sweet and aromatic. Finally it has some orna- 

 mental value, being evergreen and fragrant throughout. 

 The fls., which are not very showy, are white, ^in. 

 across, and borne in small panicles, each branch of which 

 is parted into three. It has been advertised in S. Calif.
