===Plant Description===
 +
This native perennial plant is up to 1' tall, but more commonly ½' or less. It consists of a rosette of basal leaves, which sometimes produces an inflorescence on a short stalk during the spring. The basal leaves are up to 2" long and ½" across; they are oblanceolate, with smooth margins. There is a single prominent vein on the upper surface of each basal leaf, while the lower surface is white and hairy. There are small alternate leaves along the pubescent flowering stalk; they are narrowly lanceolate or linear. At the top of each stalk, a plant produces a few flower heads about 1/3" long that are either staminate or pistillate. These flower heads resemble compact tufts of white hair. Howell's pussytoes spread by means of horizontal stolons that are hairy and have small alternate leaves that are narrowly lanceolate or linear. This plant often forms small colonies.<ref name=":0">Illinois Wildflowers. Retrieved from

Plant Description

This native perennial plant is up to 1' tall, but more commonly ½' or less. It consists of a rosette of basal leaves, which sometimes produces an inflorescence on a short stalk during the spring. The basal leaves are up to 2" long and ½" across; they are oblanceolate, with smooth margins. There is a single prominent vein on the upper surface of each basal leaf, while the lower surface is white and hairy. There are small alternate leaves along the pubescent flowering stalk; they are narrowly lanceolate or linear. At the top of each stalk, a plant produces a few flower heads about 1/3" long that are either staminate or pistillate. These flower heads resemble compact tufts of white hair. Howell's pussytoes spread by means of horizontal stolons that are hairy and have small alternate leaves that are narrowly lanceolate or linear. This plant often forms small colonies.[2]


Bloom Period

May to July[3]


Distribution

Occurring on both sides of the Cascades crest in Washington; Yukon Territory to California, east to the Rocky Mountains, northern Great Plains, Great Lakes region, and northeastern North America.[3]


Habitat

Mesic to dry black soil prairies, clay prairies, slopes of open woodlands, dry meadows in woodland areas, savannas, shale glades, eroded clay banks, pastures, abandoned fields, and roadsides.[2]


Uses

First Nations

Use by the Bellacoola People (Bí’lxula) as an analgesic[4], and by the Ojibwe (Anishinaabeg) as an infusion to purge afterbirth and to heal from child birth[5].

Other uses

Could be grown in rock gardens for spring bloom.


Propagation

[Protocol from Native Plant Network]

Seed

Antennaria howellii, photo: Lisa Hintz

Seed sample from: 2009

Average Measurement: 1.1 x 0.3 x 0.2

Measurement Range: L: 0.9 - 1.5, W: 0.2 - 0.4, D: 0.1 - 0.3

Features

Shape: Slightly larger than Anaphalis margaritacea and has lighter, glossier, and more dimpled hilum.

Color: Brown.

Additional Structures: At opposite end of hilum is pappus of white hairs that attach in a ring around the end of the seed. Pappus is significantly longer that seed.

Surface: Seed is slightly grooved, hairy, and covered with white globules.

Could be confused with: Anaphalis margaritacea


Latitudinal Cross Section: elliptical Anthowelliilat.png

Longitudinal Cross Section: elliptical ARHI-long-crosssection.png


Basic Explanations and Assumptions:

The dimensions for the seeds are length x width x depth. The location of the hilum is used as the base of the seed, and the length is measured from hilum to the opposite apex. Where a style is present, the length is measured from the hilum to the bottom of the style. Width is measured at a right angle to the length at the widest part. Depth is measured at a right angle to the intersection of height and width lines.

Measurements included are the mean average for each measurement of ten separate seeds.

All measurements in millimeters unless otherwise noted.
