Description
 
 

Night-flowering catchfly is a 8 to 32 tall, erect, annual forb that rises from a slender taproot. When young the plant forms a basal rosette of leaves. Later it sends up flowering stems.

The stems are erect and branched on the upper part. They are densely hairy and are covered with sticky glandular hairs near the top. There are up to 10 pairs of leaves on the stem.

Basal leaves are broad, inversely lance-shaped with the attachment at the narrow end, 2⅓″ to 4¾ long, less than ¾ to 1¾ wide, densely hairy, and on leaf stalks. Stem leaves are narrower and opposite, with up to 10 opposite pairs of leaves on the stem. They are lance-shaped to broadly elliptic, up to 4¾ long and 1½ wide, becoming progressively smaller as they ascend the stem. They taper gradually to a pointed tip with straight sides along the tip, and are attached to the stem without a leaf stalk. They are conspicuously veined and densely hairy on the upper and lower surfaces, the upper leaves covered with sticky, glandular hairs. The margins are untoothed.

The inflorescence is open, loosely-branched cluster of 3 to 15 flowers. Each cluster is subtended by a pair of to 2 long, leaf-like, narrowly lance-shaped bracts.

Flowers are ¾ to 1 wide when fully open on a stalk that is longer than the calyx. They have both male and female reproductive organs (perfect). They are fragrant. They open in the evening and are pollinated by moths.

The sepals are fused at the base into a tube (calyx) terminating in 5 short, erect lobes. The calyx is to 1 long and about wide when in flower, swelling to wide when in fruit. It is narrowed at both ends and constricted at the base. It has 10 major veins that are raised on the surface (prominent), forming ridges, with a network of veins between them.

The 5 petals are white, often tinged pink, and yellowish underneath. They are horizontally spreading. They have 2 deep, narrow lobes, and a stalk-like narrow base (claw). There are 10 stamens that are shorter than the petals and 3 styles, also shorter than the petals.

The fruit is a 3-chambered capsule the same size as or slightly longer than the calyx, with 6 teeth at the top that are bent backward.

Glossary

Bract

Modified leaf at the base of a flower stalk, flower cluster, or inflorescence.

 

Calyx

The flower cup. May be the group of outer floral leaves (sepals) collectively, or a tube with lobes.

 

Claw

A stalk-like narrowed base of some petals and sepals.

 

Glandular hairs

Hairs spread over aerial vegetation that secrete essential oils. The oils act to protect against herbivores and pathogens or, when on a flower part, attract pollinators. The hairs have a sticky or oily feel.
