Pediocactus knowltonii, commonly known as Knowlton's cactus or Knowlton's pincushion, is a species of small cactus native to the southwestern United States. Primarily found in the states of Colorado, New Mexico, and Utah, it is a member of the Cactaceae family and is considered a rare and endangered species.
Knowlton's cactus typically grows in dry, desert-like habitats with well-drained soil, rocky slopes, and sandy plains. It is a small, globular cactus that usually reaches a height of around 4 to 8 centimeters and a diameter of 5 to 10 centimeters. It is characterized by its distinctive cylindrical and elongated tubercles with prominent grooves or ridges. Each tubercle bears numerous spines that can vary in color from yellowish or reddish to brown or black.
During blooming season, usually in late spring or early summer, Knowlton's cactus produces beautiful, solitary, funnel-shaped flowers. These flowers are typically pink, lavender, or white in color and have numerous petals arranged in a circular formation. The blossoms are relatively large compared to the size of the cactus and can reach up to 4 centimeters in diameter.
Due to its limited natural range and habitat disturbance, Pediocactus knowltonii faces significant threats, including habitat loss, illegal collection, and climate change. Conservation efforts aimed at protecting its natural habitat and population are crucial for the continued survival of this unique and beautiful cactus species.
The etymology of the word "Pediocactus knowltonii" can be broken down as follows:
1. Pediocactus: The genus name "Pediocactus" comes from the Greek word "pedion", meaning "level ground" or "plain", and "kaktos", which translates to "spiny plant" or "thistle". Thus, Pediocactus refers to a group of cacti that typically grow close to the ground, resembling thistles.
2. Knowltonii: The specific epithet "knowltonii" is derived from the last name of Chester A. Knowlton, an American botanist known for his contributions in the field of cacti and succulents. This name is given to honor his work and achievements related to the study of Pediocactus species.
