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

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

 sand, and w^et thoroughly by pouring on boiling water 

 — to prevent trouble from insects and to heat the soil. 

 When the soil lias cooled sufficiently but is still warm, 

 sow the seeds verv thinly in the boxes, so that the 

 plants mav Ik- 1 in", apart". Cover seeds very slightly

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

 tjrniiiiKitii.n appear before the leaves, sift on more

 ,sli-niii^, siocky 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 weakest 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 geniis 

 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 Petroselinum, 

 Anethum, Imperatoria, Tommasinia, Pastinaca, Tied- 

 mannia, Lomatium. 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 tliis vi.w 

 we agree, and the cult, species are referred lc> tlii^ i,. nn^

PEOMUS (said to be a Chilean name). Syn., Bold(-)a, 

 Ilol,!,„. .]fn,iu,nncew. A genus of one specii's, the 

 Chilraii Holdo. a small tree of considerable economic 

 intirrst. II liiis iN.'fodinglv h.ird wood, vrhich is used 



mental value, being evergnin and tragrant tliron-lioiit. 

 The fls., which are not very showy, are white, 'jin. 

 across, and borne in small panicles, each bnimh 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; 

 ilisk investing the calyx-tube pilose within; stamens 

 female fls. smaller, the lobes more inequal.
