of the support, where they assume a different closer stouter 
growth and produce flowers. 
l. H. Helix. Common Ivy.—The varieties of this are 
numerous and handsome. Flowering specimens, it is said, may 
be distinguished by the pedicels and calyx being clothed with 
6- to 8-rayed stellate hairs. But the names are almost suffi- 
ciently descriptive of the peculiarities of the garden forms, as: 
pedata, palmatu, rugosa, lucida, sagittefolia, minor marmo- 
rata, area margindta, argéntea margindta, ete. There 
are also green and variegated arborescent forms, and others 
with white, yellow, or black berries. 
2. H. Canariénsis, or Hibérnica. Usually known in gar- 
dens as the Irish Ivy.—Stellate hairs of the inflorescence with 
13 to 15 rays. Algeriénsis is one of the best green-leaved 
varieties referred here. Though the variegations are not so 
numerous and varied, there are some very desirable, generally 
of more robust and vigorous growth than in No. 1: pdllida, 
maculata, argénteo-marginata, Cavendishit, etc.; arboréscens 
and cordifélia are ‘Tree Ivies.’ 
3. H. Regneriana or Colchica. Giant Ivy.—Inflorescence 
furnished with 2-lobed scales, each lobe again divided into 7 
to 10 teeth. The leaves of this form are very large, thick 
and leathery. There is a variety, arbérea, both green and 
variegated. 
Orvsr LVI—CORNACE:. 
Shrubs; trees, or herbs. Leaves simple, alternate or opposite, 
deciduous or evergreen, exstipulate. Flowers usually small 
and inconspicuous, in terminal cymes or panicles, or amentaceous 
or capitate with a coloured involucre. Calyx-tube adherent to 
the ovary. Petals none, or 4 or 5, rarely more. Stamens 4 
or 5. Fruit drupaceous, 1- to 4-celled, or with 1 to 4 1-seeded 
stones. A small order of about seventy-five species, widely 
scattered throughout the world, but most abundant in the 
temperate regions of the north. 
1. CORNUS (including Benthamia). 
Shrubs, small trees, or herbs with usually opposite leaves 
and hermaphrodite tetramerous flowers with or without an
