PARK AND CEMETERY. 
Valeriana is a 
large genus of 1 50 
species distributed 
over Europe, Asia, 
Africa, and Amer- 
ica. V. edulis is 
used as a food by 
the Digger Indians. 
V. scandens is a 
South Florida clim- 
ber, V. rotundiloba 
is Chilian, and there 
are five or six other 
American kinds. 
The most of those in gardens however are European. 
V. Phu from the Caucassus has a variegated form. 
Two are British; V. officinalis occupies very differ- 
ent stations and varies greatly in size. 
Centranthus has 8 species mostly from Mediter- 
ranean regions, but C. ruber and its white variety is 
found in England, and thrives especially in old 
chalk pits and similar places on the Kentish side of 
the lower Thames. 
Fcdia cornucopia is a monotypic annual from 
Mediterranean regions bearing reddish, pink or rose- 
lilac flowers, with several names for the different 
forms. 
Valenanella , one species of which is known as 
“Cornsalad” has about 55 species natives of North 
America, North Africa, temperate Asia and Europe. 
V. longiflora Nuttallii is an Arkansas plant said to 
be worth cultivating. 
Dipsacus is the type of another tribe. They 
are known as “teasels” and have a dozen or so of 
species two of which have naturalized in the United 
States. 
Scabiosa has 110 species of annual and peren- 
nial herbs. Several of the best are in gardens, the 
East Indian S. atropurpurea in variety being one of 
the most familiar. The British “field scabious,” 
S. arvensis, with various shades of purple and whit- 
ish flowers is a pretty plant whose blossoms turn 
bright green when exposed to tobacco smoke. 
Morina in 8 species from Central and Western 
Asia, and Cephalaria in 26 species from Europe, 
Western Asia and Africa, are other genera of the 
tribe. C. Tartarica with light yellow flowers is a 
good species for those who desire a plant of five or 
six feet high, which may be planted in the centre 
of a round bed and surrounded by Scabiosa Cau- 
cassica for instance. 
Calycerece is a small tribe of three genera some 
of whose 20 species often ascend to great elevations 
on the southern Andes, and are scarcely at all 
known in cultivation. 
Vernonia “iron weeds” have 500 species from 
North and 
South America, 
tropical Asia 
and Australia. 
Some grow on 
the ground and 
attain a height 
of eight or ten 
feet. The dry 
ground species 
are commonly 
smaller. Four 
or five species 
are in gardens 
mostly with flowers in some shade of purple. 
Stokesia cyanea is a monotypic plant found from 
S. W. South Carolina to E. Louisiana. It is a low 
growing perennial with handsome blue — purple 
flowers in late summer. Hardy at many parts north. 
Ageratmn has 25 species of tropical or sub- 
tropical American perennials or annuals. A Mexi- 
canum has become a cosmopolitan and pestiferous 
weed in the Eastern tropics, and the despair of 
many coffee planters. There are however many 
handsome dwarf and variegated forms in gardens. 
Stevia has 80 or more species, all American. 
Eupatorium has 560 species scattered over the 
tropical and temperate regions of the world; Aus- 
tralia however has but one species. E. ccelestinum 
sold as “hardy Ageratum” is a good perennial gar- 
den plant with flowers resembling the greenhouse 
Ageratums. It is a Fiorida and Texas species, but 
has escaped from g irdens and become wi'd in some 
parts of New Jersey.
