HYDRANGEA FAMILY. _Hydrangeaceae._

Shrubs or trees, with opposite leaves and no stipules. The flowers are

in clusters and usually perfect, but sometimes those at the margins of

the clusters are without pistils or stamens and larger than those in

the middle; the calyx usually with four to ten sepals, and in sterile

flowers often conspicuously enlarged; the petals four to ten; the

stamens eight to many; the ovary wholly or partly inferior; the styles

separate or united, sometimes lacking; the fruit a capsule. Many very

ornamental garden shrubs, such as Deutzia and Hydrangea, are included

in this family.

There are several kinds of Fendlera, natives of North America; shrubs,

with white or pink flowers, with four sepals and four petals, the

latter with claws. The eight stamens have two-forked filaments and the

ovary is partly inferior, with four styles.

Spring

Among the many beautiful plants to be found in the Grand Canyon one of

the most conspicuous is the Fendlera. It is a tall, handsome shrub,

growing along the upper part of Bright Angel trail, and in May it is

covered with charming white blossoms. These flowers measure an inch

across, and have cream-white or pale pink petals, narrowing to a claw

at the base, and purplish sepals, and they grow in clusters of three

or four, mixed with pink buds, on the ends of short branches. The

small oblong leaves have three nerves and the wood is tough and gray,

with deeply furrowed bark. Though their scent is rather unpleasant,

the flowers are lovely and look just like some novel variety of

fruit-blossom, but this resemblance is deceptive for they produce

nothing but dry pods.

There are a good many kinds of Philadelphus, natives of North America,

Asia, and Europe; shrubs, with large, white or cream-colored

flowers; the calyx top-shaped, with four or five lobes; the petals

four or five; the stamens twenty to forty, inserted on a disk; the

ovary inferior, with three to five styles; the capsule top-shaped,

containing many oblong seeds. These plants were named in honor of King

Ptolemy Philadelphus. They are often called Mock-Orange, because the

flowers often resemble orange-blossoms. The commonest name, Syringa, is

confusing, because that is the generic name of the Lilac.

_Philadélphus Califórnicus_

=White

Summer

Cal., Oreg., Wash.=]

In June and July, in the high Sierras, up to an altitude of four

thousand feet, this lovely shrub forms fragrant thickets of bloom. It

looks very much like the familiar garden Syringa and the smell is just

as delicious. The bush is from four to twelve feet high, with smooth,

pale, woody stems, dark-green leaves, sometimes slightly toothed,

very smooth and shiny, and pretty flowers, in clusters at the ends of

the branches. They are each about an inch across, with four or five,

cream-white petals, rolled in the bud, and a golden center, composed of

numerous, bright-yellow stamens.

_Philadélphus microphýllus_

=White

Summer

Ariz., Cal., New Mex.=]

A small shrub, not nearly so handsome as the last, from two to three

feet high, with slender, pale-gray, woody stems, branching very

abruptly. The small leaves are smooth and very bright green on the

upper side, but the under side is very pale and covered with close

white down. The flowers are much smaller than the garden Syringa, with

white petals and numerous yellow stamens, the calyx reddish outside and

downy within, and have a delicious smell, like lemon-blossoms. This

pretty little shrub may be found growing in small shady canyons, in

northern Arizona and elsewhere in the Southwest.
