Plagiobothrys tenellus (Nutt. ex Hook.) A.Gray | |
Plagiobothrys tenellus is a species of flowering plant in the borage family known by the common names Pacific popcornflower and slender popcornflower. It is native to western North America from British Columbia to Mexico, where it is a common member of the flora in several types of habitat.
Boraginaceae, the borage- or forget-me-notfamily, includes a variety of shrubs, trees, and herbs, totaling about 2,000 species in 146 genera found worldwide.
British Columbia is the westernmost province of Canada, located between the Pacific Ocean and the Rocky Mountains. With an estimated population of 5.016 million as of 2018, it is Canada's third-most populous province.
Plagiobothrys tenellus is an annual herb producing several erect stems up to about 30 centimeters tall. It is very hairy in texture, the hairs long and white. The leaves are located in a basal rosette around the stem and there are a few smaller ones along the stem itself. The inflorescence is a coiling branch bearing many small five-lobed white flowers. Each flower is 1 to 3 millimeters wide. The fruit is a tiny cross-shaped nutlet covered in bumps and grooves.
An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed. The modifications can involve the length and the nature of the internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. Inflorescence can also be defined as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern.
