SPIRAEA ARUNCUS. ( Gardening ). 
with Chrysobolanece , a tribe of 12 genera which are 
nearly all tropical. Chrysobololanus Icaco, and C. 
oblongifolius extend to the United States. 
Primus, is a large and familiar genus of 96 spec- 
ies, natives of Europe, sub-tropical and temperate 
Asia, and extending from temperate to tropical 
America. None seem to be truly African or Aus- 
tralian. Modern botanists sub-divide the genus 
into sections of which the Peach, the Apricot, the 
Plum, the cherry, the bird-cherry, and the cherry- 
laurels are typical. P. Caroliniana represents the 
latter, and it is a very handsome and popular ever- 
green in the states south of North Carolina, better 
adapted for standards than the “sweet bay,” and 
excellent as a hedge plant. P. lauro-cerasus, var. 
Caucasica, has been tried under north walls and en- 
dured for a time in Maryland or even further north- 
wards, but no variety of broad leaved laurel is to be 
relied upon where zero frosts occur. I have seen 
40 year old plants cut to the ground in middle Eng- 
land. P. ilicifolia is the Pacific coast expression of the 
cherry-laurel, P. lusitanica extends from Western 
Europe to the Azores. Most all the varieties are 
charming evergreens for southern points, with 
racemes of whitish flowers much like the bird-cher- 
ries. The double flowering and other forms of the 
peach, plum and cherry are among the most charm- 
ing objects in the gardens of the temperate regions, 
and nowhere are they finer than in the milder parts 
of the United States. Some varieties are short 
lived, but they are cheap, and should be replanted 
as often as they threaten to succumb. Upwards of 
100 forms of the genus are in cultivation, encum- 
bered by an endless synonomy.

Nuttalia is a monotypic genus from the Pacific 
States. 
Spirea is a large genus of at least 50 species and 
many varieties. They are European, Asiatic and 
American, herbaceous perennials, or shrubs, and 
in some few species at southern points sub-ever- 
green. Japonica in vars. Lindleyana and Canton- 
ensis are among these. 
Neillia is a closely allied genus of about a half 
dozen species from North America and the East 
Indies; N. opulifolia being often sold ss a spirea. 
Stephanandra has 3 species from China and 
Japan. S. flexuosa is in nurseries. 
Exochorda is in 2 or 3 species from Northern 
China, Persia, etc. E. grandiflora is a well-known 
shrub, sometimes reaching to 20 feet in diameter 
by 10 or 12 feet high. E. Alberti is unknown to 
me but in European gardens. 
Gillenia is an herbaceous genus in 2 species, 
both North American, G. trifoliata and varieties 
sometimes being called spireas. 
Kerria has 1 or 2 species from China with double 
and variegated varieties. K. Japonica is a well- 
known shrub, but often neglected for newer but 
rarely better things; it flowers twice a year. 
Rhodotypus also from E. Asia is monotypic; it 
is sometimes called a “white kerria.” and will also 
sometimes flower twice. 
Neviusia recently brought into nurseries is 
monotypic and a native of Alabama.
