Adenophyllum porophylloides, San Felipe Dogwood

San Felipe Dogwood has small but pretty flowers of yellow, orange and red-orange. The flowers contain numerous resin glands on the phyllaries and leaves, which emit a rather unpleasant odor. Adenophyllum porophylloides San Felipe Dogwood fruits are small achenes with pappus scales composed of basally fused bristles. This species blooms from March to June and again from October to December with ample summer rainfall. Adenophyllum porophylloides San Felipe Dogwood are small native subshrubs with a woody base and multiple erect slender stems and branches. Leaves are green and pinnately lobed with small oil glands at base of each lobe at tip. Adenophyllum porophylloides San Felipe Dogwood or San Felipe Dyssodia is found in AZ, CA and NV and prefers elevations from50 to 4,000 feet and is found in washes, mesas, and dry rocky slopes in deserts, open scrub and woodlands. It is found in both Sonoran and Mojave Deserts. Adenophyllum porophylloides

Synonyms: (Dyssodia porophylloides)

Status: Native

Duration: Perennial

Size: 8 to 20 inches (20-50+ cm.) or so.

Growth Form: Subshrub; has thick woody base; plants erect or ascending, multiple stems, stems without surface ornamentation such as hairs, scales or bristles, (glabrous); stems and branches slender; plants with disagreeable odor, aromatic to some.

Leaves: Dark green; basal leaves are arranged opposite along the stem and the upper (cauline) leaves are alternate; the leaves are somewhat thick and pinnately lobed, these lobes are narrow and 3 to 5 parted; leaf shapes variable from linear to cuneate or oblanceolate; the leaves have very small but prominent secretory oil or resin producing structures (glands) located at the base of each lobe on the tips.

Flower Color: Yellow; becoming orange or red-orange with age; the flower heads, ½ x 1 inch, (1.3-2.5 cm) are in corymbose arrays on the tips of supporting stalks (½ inch to 3 inches (20-80 cm)) called peduncles; the flower heads may have both ray florets, (10 to 14 per head) whose corollas are yellow becoming red-orange; and disk florets, (25 to 40 per head) which have yellow-orange corollas; there are 12 to 20 bracts or phyllaries surrounding the flower heads (involucre), these lanceolate phyllaries have resin glands; the fruit is a brownish cypsela with basally fused (connate) straight stiff hairs (bristles).

Flowering Season: March to June and again from October to December, with ample summer rainfall.

Elevation: 50 to 4,000 feet (15-1,200 m) .

Habitat Preferences: Washes, mesas, dry, rocky slopes in deserts, alluvial fans, open scrub and woodlands; found in both Sonoran and Mojave Deserts.

Recorded Range: San Felipe Dogwood is relatively rare in the United States where it is limited in distribution to AZ, CA and NV. This species is also native to northern Baja California, Baja California Sur and northwestern Sonora Mexico.

North America & US County Distribution Map for Adenophyllum porophylloides.

Genus Information: In North America there are 4 species and 4 accepted taxa overall for Adenophyllum. World wide, The Plant List includes 62 accepted species names and includes a further 10 of infraspecific rank for the genus Adenophyllum.

The genus Adenophyllum was published in 1807 by Christiaan Hendrik Persoon.

In the Southwestern United States: Arizona has 4 species of Adenophyllum, California and Nevada each have 2 species, New Mexico and Utah each have 1 species and Texas has 0 species. All data is approximate and subject to taxonomic changes.

Comments: San Felipe Dogweed is both a Mojave and Sonoran deserts species. Through its numerous resin glands this species emits a pungent rather unpleasant odor although it is aromatic to some.

At a quick glance San Felipe Dogweed looks superficially like its closely related cousin Odora, Porophyllum gracile, which has significant differences in the flower head. They both also have strong disagreeable odors.

Importance to Wildlife, Birds and Livestock
Adenophyllum porophylloides may likely be eaten by birds and small mammals.

Special Value to Native Bees, Butterflies and Insects
Adenophyllum porophylloides flowers may be visited by butterflies, bees and other small insects.

Etymology:
The genus Adenophyllum (Adenophyl'lum, adenophyllus:) is from the Greek word for "gland-leaf" or "having glandular leaves". The genus Adenophyllum was published in 1807 by Christiaan Hendrik Persoon.

The specific epithet, phorphylloides (porophyllo'ides:) mean "with leaves like those of Porophyllum". Porophyllum (Porophyl'lum:) is from the Greek "poros", "a passage or pore," and phyllon, "leaf," thus literally "pore-leaf," because of the translucent glands dotting the leaf which give it a punctate appearance.
