Passerina (plant) large enough to cover them. This gives the plants a characteristic plaited or corded appearance. The flowers of some species are borne in terminal spikes, whereas other species bear them in a four-flowered head. Bracts, usually broader than leaves and larger than the flowers, subtend each flower. This is one helpful distinction between specimens of "Passerina" and plants in the genus "Struthiola". The calyx has four sepals, forming a flask-shaped or subcylindrical tube. At the mouth the sepals spread into lobes that are shorter than the tube. There are no petals, but the lobes of the sepals are quite colourfully
Nemophila breviflora Nemophila breviflora Nemophila breviflora is a species of flowering plant in the borage family known by the common names basin nemophila, Great Basin nemophila, and Great Basin baby-blue-eyes. It is native to southwestern Canada and the northwestern United States, where it generally grows in wooded and forested areas in thickets and moist streambanks. It is an annual herb with a fleshy, somewhat prickly stem growing 10 to 30 centimeters tall. The alternately arranged leaves are divided into several wide, pointed lobes. Flowers are solitary, each on a short pedicel. The flower has a calyx of sepals each a few millimeters
