Ciliated Pearlwort (Sagina Ciliata, Fries = 5. Patida, Jord.)

The habitat of this species is dry places, sandy heaths. The habit is erect or spreading. The plant is smooth or glandular, downy. The central stems are flowering and erect or ascending, like the branches, not rooting. The leaves are fringed with hairs (hence ciliata), blunt-pointed, linear. The flowers are white. The 2 outer sepals are pressed close to the capsule, pointed, hardly shorter than the capsule, the tips spreading, glandular, hairy, like the flower-stalks. The petals are very small. The capsule is ovate to narrow, rounded below, stalked. The plant is 1-6 in. high, flowering from May to July, and is a herbaceous annual.

Procumbent Pearlwort (Sagina Procumbens, L.)

The habitat of this species is waste places, paths, banks. The habit is prostrate. The stems are numerous, with long, tufted, axillary branches from a central rosette, the primary shoot flower-less, long-rooting, lateral, slender, the ultimate branches tufted. The leaves are smooth, blunt, with a short, blunt point, awned. The flowers are solitary, as a rule, with the parts sometimes in fives, white, the sepals spreading in fruit, blunt, shorter than the capsule. The petals are very small, blunt, sometimes wanting. The tip of the stalk is bent-back after flowering, then erect. The styles are bent-back after flowering. The capsule is longer than the sepals. The plant is 1-8 in. in length, flowering from May to September, and is a herbaceous perennial.

Slender Pearlwort (Sagina Subulata, Presl)

The habitat of this plant is heathy places, heaths, dry pastures, dry gravelly, sandy places. The plant has the rosette habit, and is tufted. The stem is prostrate, glandular, hairy. The leaves are linear, awned, fringed with hairs. The flowers are white, the petals as long as the capsule, longer than the calyx. The flower-stalks are glandular, very long, the tip bent-back in fruit, then erect. The sepals are closely pressed, blunt, glandular, lance-shaped. The capsule is longer than the sepals, egg-shaped, narrowed, round below, stalk-less. The plant is 1-2 in. in height, flowering between June and August, and is a herbaceous perennial.

Knotted Spurrey (Sagina Nodosa, Fenzl)

The habitat of this plant is moist heaths, sandy places, wet places. The plant has more or less the loose rosette habit, or is prostrate. The plant is smooth as a rule. The primary stem is short, and does not flower, the lateral stems are prostrate, then ascending at the base, 2-6 in. long. The stems are leafy to the top of the branches, which are curved, wiry, rooting at the nodes. The leaves are linear, awl-like, acute, hairless, with leafbuds in the axils, tufted, longer than the sepals. The flower-stalks are short, erect, 1-2-flowered. The flowers are large, white. The petals are longer than the sepals, which are blunt, oblong. The capsules exceed the sepals. The plant is 2-6 in. high, flowering in July and August, and is a herbaceous perennial.
