Thalictrum dioicum | |
Thalictrum dioicum, the early meadow-rue [1] or quicksilver-weed, is a species of herbaceous plants in the family Ranunculaceae. Plants are typically upright growing woodland natives from Colorado Rocky Mountain forests to central and eastern North America including parts of south eastern Canada. This species has dioecious plants, with male and female flowers on separate plants blooming in early to mid spring.
Thalictrum dioicum grows from 30 to 80 cm tall, from upright caudex, with yellow-gold colored – thick fibrous roots. New caudexes are generated each year by the current years plant and the old caudex withers away in the fall and early spring of the next year. In early spring plants grow, producing glabrous or glandular leaves. both basal and cauline leaves are produced that have long petioles. Leaf blades are 1-4×-ternately compound with leaflets reniform or cordate to obovate or orbiculate in shape. The leaflets are 10–45 mm wide with lobed margins often crenate, and the undersides are normally glabrous or glandular. Inflorescences are panicles or corymbs produced terminally and axillary with many flowered branches. The flowers have no petals but have greenish colored, 1.8–4 mm long sepals sometimes tinted purple. The sepals are ovate to obovate or oval in shape. On male plants, the flower filaments are the most showy part of the hanging flowers, being yellow to greenish yellow in color and 3.5-5.5 mm long. The filaments end in anthers 2–4 mm long that are mucronate to acuminate in shape with purple colored stigma. After blooming, female plants if fertilized, produce green fruits called achenes. Each flower that is fertilized typically produces (3-)7 to 13 achenes that are not reflexed and sessile or nearly so in tight clusters. The achenes are ovoid to ellipsoid in shape and not laterally compressed, 3.5–5 mm long, glabrous, very strongly veined, with 1.5 to 3 mm long beaks, ripening in mid summer. [2]
Plants are grown in shade gardens for their attractive lacy foliage that is reminiscent of columbines or maiden hair fern. The males produce more showy flowers than the female plants, blooming in early spring with the flowers and foliage rising out of the ground in club-like clusters with the basal leaves unfolding first. Plants start to flower before the compound leaves have completely unfolded. This species, like some others of its genus, is pollinated via wind action (anemophily). [3] Males start off the year taller than the females, but as the fruits grow females are taller typically in summer.

Thalictrum thalictroides, synonym Anemonella thalictroides, the rue-anemone, is a herbaceous perennial plant native to woodland in eastern North America. It has white or pink flowers surrounded by a whorl of leaflets, and it blooms in spring.
Anemone parviflora, the northern anemone, or small-flowered anemone, is a herbaceous flowering plant species in the buttercup family Ranunculaceae. Plants grow 10 to 30 cm tall, from a thin, 2 mm thick rhizome. Stem leaves without petioles, basal leaves few with long petioles and deeply three-parted. Plants flowering late spring to mid summer with the flowers composed of five or six sepals normally white or soft bluish colored, 8 to 13 mm long. The plants produce one peduncle with one solitary flower. Fruits in heads ovoid in shape, 10 mm long or less, fruits densely woolly, not winged and with straight 1 to 2.5 mm long beaks.
Anemone tuberosa, the desert anemone or tuber anemone, is a herbaceous species of flowering plant buttercup family Ranunculaceae. Plants grow 10 to 30, sometimes 40 cm tall, from a woody-like tuber shaped like a caudex. Plants with 1 to 3 basal leaves that are 1 or 2 times ternate. The basal leaves few with long petioles and deeply 3-parted with leaflets lacking stems or rarely with a stalk. Plants flowering early to late spring with the flowers composed of 8 to 10 sepals normally white or pink colored, 10 to 14 mm long. The plants produce one peduncle with one solitary flower or 2-5 flowered cymes. Fruits in heads fusiform in shape, with 7–20 cm long pedicels. Fruits called achenes measure 2.5-3.5 mm long and 2–2.5 mm wide with a rounded outline and flat in shape, densely woolly, not winged also with straight 1.5 mm long beaks.
This page provides a glossary of plant morphology. Botanists and other biologists who study plant morphology use a number of different terms to classify and identify plant organs and parts that can be observed using no more than a handheld magnifying lens. This page provides help in understanding the numerous other pages describing plants by their various taxa. The accompanying page—Plant morphology—provides an overview of the science of the external form of plants. There is also an alphabetical list: Glossary of botanical terms. In contrast, this page deals with botanical terms in a systematic manner, with some illustrations, and organized by plant anatomy and function in plant physiology.
Harfordia macroptera is a woody perennial in the family Polygonaceae commonly known as rabbit's purse. It is the sole species in the genus Harfordia, which is endemic to the Baja California Peninsula. This plant is characterized by a unique, conspicuous bladder embellished with red to purple veins that surround the fruit. The sac-like structure is actually a dramatically modified bract, and assists in dispersal of the seeds through the wind.
