Phlox hoodii, the spiny phlox or carpet phlox, is a species of phlox. It is a plant of western North America, where it is a common flower in sagebrush country, mostly growing in dry lithosol habitats.[3] It is among the first plants to bloom in spring, after the snow has melted. Its distribution extends from Alaska to Arizona.[4] There are many subspecies.
This perennial herb is variable in morphology, but usually forms a tight mat or loose clump on the ground.[4] The short stems emerge from a woody taproot and caudex unit and the plant form is no more than 13 centimetres (5 in) tall.[4] The abundant tiny, sharp-pointed leaves are oppositely arranged and barely exceed one centimetre (1⁄3 in) long. The herbage is hairy in texture, the hairs short to long, woolly to cobwebby.[4] The appearance of the plant is almost mosslike until blooming.[5] The inflorescence is a solitary flower in shades of white, pink, or blue.[4] It has a tubular throat about one centimetre (1⁄3 in) long spreading into a flat five-lobed corolla.
Taxonomy
[edit]In 1823 John Richardson scientifically described a new species in the Phlox genus with the name Phlox hoodii. Together with its genus it is classified in the Polemoniaceae family and the species has six accepted subspecies and one variety according to Plants of the World Online.[2]
- Phlox hoodii subsp. canescens – Native from British Columbia to New Mexico[6]
- Phlox hoodii subsp. glabrata – Native to Idaho, Montana, Nebraska, North Dakota, South Dakota, and Wyoming[7]
- Phlox hoodii subsp. hoodii – Native to Alaska and the Yukon and from southern Canada to Arizona[8]
- Phlox hoodii subsp. lanata – Native from Washington to Arizona[9]
- Phlox hoodii var. madsenii – Native to Utah[10]
- Phlox hoodii subsp. muscoides – Native from California to North Dakota[11]
- Phlox hoodii subsp. viscidula – Native to Alberta, British Columbia, Idaho, Montana, Oregon, Washington, and Wyoming[12]
Phlox hoodii has 14 synonyms of the species or of four of its subspecies.[13]
