urges all to care for each seed. Pill shallow boxes with 

 fine, light soil, say an even mixture of leaf -mold and 

 sand, and wet thorouKhly l.y iMiiiriTJi; on boiling water 

 —to prevent trouble fmiti ins.-cts .iml to heat the soil. 

 When the soil has coolol sullirii-ntly l.ut is still warm, 

 sow the seeds very thinly in tin- l.oxes, so that the 

 plants may be 1 in. apart. Covi-r s.-eds very slightly 



with a little sifted sand, and place a piece of slate or 

 glass on top of the boxes. If the white root points of 

 germination appear before the leaves, sift on more 

 sand, and watch closely. When the small leaves ap- 

 pear, remove slats and give plenty of light, to produce 

 strong, stocky plants. The soil may now need water, 

 which should be applied very gently, that the tiny seed- 

 lings may not be displaced. Later the larger plants 

 may be transplanted from seed-boxes into other boxes 

 or pots. As the wealsest plants frequently give the 

 finest blossoms, care should be taken to preserve every 

 plant until the blossoms appear.

 There are many views as to the limits of the genus 

 Peucedanum, which is equivalent to saying that it has 

 no limits. Bentham & Hooker made it a most complex 

 group, comprising about 100 Old World and New World 

 species, and including such genera as Petroselinttm. 

 Anethum, Imperatoria, Toramasinia, Pastinaca, Tied- 

 mannia, Lomatiura. Coulter & Rose, the latest Amer- 

 ican monographers (Monogr. of the N. A. Umbell., U. S. 

 Dept. Agric. 1900), remove the American species and 

 accept Rafinesque's genus Lomatium. With this vi.w 

 we agree, and the cult, species are referred to tliis i.'iiius

Lomatiums are all western American plants, of about 

 60 species, growing in dry .soil. They are stemless (or 

 nearly so) perennial herbs from tuberous or fusiform 



roots, and compou

PEtMUS (said to be a Chilean name). Syn., Boldfia, 

 Boldea. Monimidcew. A genus of one species, the 

 Chilean Boldo, a small tree of considerable economic 

 interest. It 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 lvs. are 

 used in medicine. The fniits 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, Hin. 

 across, and borne in small panicles, each branch of 

 which is parted into three. This tree has been adver- 

 tised in southern California. The male tree has been 

 cult, under glass in Europe, but scarcely outside of 

 botanic gardens and only for its economic interest. 



Generic characters: male fls. with 10-12 perianth- 

 lobes, overlapping in 2-3 series, the outer ones herba- 

 ceous or membranous, the inner ones more petal-like; 

 disk investing the calyx-tube pilose within; stamens 

 female fls. smaller, the lobes more inequal.
