    There are at least 25 species of Townsendia, all in Western North America.  Determining the exact species of Townsendia is, as Intermountain Flora puts it, "notoriously difficult", because they share many similar characteristics and the characteristics are variable. 

    The Townsendia genus was named by William Jackson Hooker in 1833 for David Townsend of West Chester, Pennsylvania.  Townsend was a banker active in civic affairs and he was a very talented amateur botanist.

Townsendia annua
Townsendia annua
Asteraceae (Sunflower Family)

Semi-desert, foothills. Woodlands, openings. Spring.
Canyons of the Ancients National Monument, April 27, 2005.

This delightful miniature is often found on hot dry hills and occurs in patches of just a few plants or in massive colonies.  It ranges from an inch to seven inches tall and most often occurs with just a single, upright stem as shown at left or, less often, in a sprawling mat as shown on the next Townsendia page.  Leaf and stem of this annual are hairy and basal leaves are commonly dry by flowering time.

Bassett Maguire (1904-1990) collected the first specimen of this plant for science in 1936 in Cottonwood Wash near Bluff, Utah, but it was not until 1957 that John Beaman (1929-) described and named the plant. 

Townsendia glabella
Townsendia glabella
Asteraceae (Sunflower Family)

Foothills. Woodlands, openings. Spring.
Mesa Verde National Park, April 26, 2007. 

This Townsendia is a rare Colorado endemic, occurring in just a few southwest counties.  In 2007, Mesa Verde National Park purchased a small parcel of land on its northeastern flank to protect one of the few locations of this plant.  T. glabella occurs only on the Smokey Hill Member of Mancos Shale, Oyster Beds.  Click for more information.

Asa Gray named and described this plant in 1881.

Townsendia incana
Townsendia incana (Easter Daisy)
Asteraceae (Sunflower Family)

Semi-desert, foothills. Woodlands, openings. Spring.
Top of Yellow Jacket Canyon, Canyons of the Ancients National Monument, April 4, 2007.

This very handsome, definitely cute, Asteraceae is one of our favorites.  Few plants have such bright, large, and numerous flowers in relation to the height and width of the leaves and stem.  Ray flowers are brilliant white but are often tinged with pink or lavender, especially on the back side.  Leaves are crowded, hairy, and taper.  Flowers often barely exceed the leaves.

Townsendia incana is quite common and once one gets to know its habitat of open sandy soils, it is easy to find.  Of the seven main species of Townsendia in the Four Corners area, T. incana is by far the most common. 

Thomas Nuttall collected the first specimen of Townsendia incana "On the Black Hills" (Nuttall's words as quoted in Intermountain Flora) on his trip with the Wyeth Expedition of 1834-1837.  The first member of the Townsendia genus was collected a decade earlier in Saskatchewan by John Richardson (for whom our very common and lovely Geranium richardsonii was named). 

"Incana’ is Latin for "hoary", and refers to the "conspicuously white-hairy stems, much whiter than the leaves...." (Intermountain Flora). As noted at the top of this page, the genus is named for David Townsend of West Chester, Pennsylvania, an avid and expert amateur botanist.

Townsendia leptotes
Townsendia leptotes
Asteraceae (Sunflower Family)

Foothills to alpine. Woodlands, openings. Spring, summer.
Lone Mesa State Park, April 26, 2009.

This Townsendia is normally a species of the high montane, sub-alpine, and alpine elevations, but in Lone Mesa State Park it is found from 7,600 to 7,800 feet on Mancos Shale where it is massively abundant in the spring.  Leaves of this species of Townsendia are narrow, up to two inches long, sparingly hairy, and sometimes surpass the flower heads, which are no more than one inch across.  This species of Townsendia surpasses all others shown on this page for massive displays of flowers.

In 1880 Asa Gray named this plant T. sericea variety leptotes from a specimen collected by Charles Parry in Middle Park, Colorado in 1864.  George Osterhout renamed it T. leptotes in 1908.  "Leptotes" is Greek for "delicate".
