Leptosiphon nuttallii is a species of flowering plant in the phlox family known by the common name Nuttall's linanthus.
It is native to much of western North America, including the Western United States from California to New Mexico and Montana, and Northwestern Mexico.[3] It is known from many types of habitat.
It is native to the Klamath Mountains, Northern California Coast Ranges and Sierra Nevada in Northern California; and the Inyo Mountains, Peninsular Ranges, Transverse Ranges, and White Mountains in Southern California.[4]
Description
Leptosiphon nuttallii is a perennial herb producing a patch of small, hairy stems up to about 20 centimeters tall. Each leaf is divided into usually five very narrow, needlelike lobes.
The inflorescence is a cluster of flowers, each with white corolla lobes about half a centimeter long each joined at a yellowish throat.
Taxonomy
Leptosiphon nuttallii was scientifically described in 1870 by Asa Gray as a species of Gilia named Gilia nuttallii. It was moved several times by various botanists before being placed in the Leptosiphon genus in 2000 by James Mark Porter and Leigh Alma Johnson. Along with the rest of its genus it is classified in the Polemoniaceae family.[5]
Subspecies
According to Plants of the World Online three subspecies are accepted:
- Leptosiphon nuttallii subsp. howellii,[6] Mt. Tedoc linanthus — a rare subspecies known from just a few populations deep within the Yolla Bolly-Middle Eel Wilderness in the Klamath Mountains, Northern California.[7] It is California Department of Fish and Wildlife and IUCN listed Endangered species, and is on the California Native Plant Society Inventory of Rare and Endangered Plants.[8]
- Leptosiphon nuttallii subsp. nuttallii – The most widespread, from Baja California to Montana.[9]
- Leptosiphon nuttallii subsp. pubescens[10] – endemic to the Eastern Sierra Nevada and Great Basin region in California and Nevada.[11]
Leptosiphon nuttallii has 18 synonyms of the species or its three subspecies, including six species names.[12]
