General Information

CLEMATIS L.

Trepadoras leñosas, en nuestras especies trepando por medio de las partes foliares retorcidas; plantas dioicas o polígamas. Hojas opuestas, ternado-, pinnati- o bipinnaticompuestas, folíolos enteros o frecuentemente irregularmente dentados, 3–7-plinervios. Inflorescencias paniculiformes, terminales o axilares, con los nudos terminales cimosos, verticilados o umbeliformes, bracteadas; sépalos 4 (5), blancos a blanco-verdosos en Nicaragua; pétalos ausentes; estambres numerosos, filamentos aplanados; carpelos numerosos y libres. Frutos aquenios lateralmente aplanados, con estilo plumoso, alargado y retenido.

Género con ca 300 especies, en las regiones templadas y tropicales de ambos hemisferios, principalmente en zonas altas; 3 especies se encuentran en Nicaragua. Una cuarta especie, C. rhodocarpa Rose distribuida desde México hasta el suroeste de Honduras, tiene las hojas maduras trifoliadas, serradas a enteras, aquenios ampliamente ovados y un par de bractéolas diminutas generalmente insertadas en la mitad de pedicelo. C. acapulcensis y C. polygama fueron tratadas en la Flora of Guatemala y Flora of Panama como C. dioica L., especie restringida a la Península de Yucatán.

    Dioecious or polygamo-monoecious, lignescent vines, climbing by means of foliar tendrils (in Central America). Leaves opposite, exstipulate, ternately, pin- nately or biternately compound, the leaflets entire to coarsely dentate, often asymmetrical, 1- to 5-plinerved, glabrous to densely sericeous, the rhachis usually pubescent, often twining. Inflorescences of cymes or umbels racemosely disposed along the bracteate, often elongate main axis, unisexual or polygamous; sepals 4-5, valvate, white, greenish or purplish, often petaloid; stamens numerous, sepa- rate, the filaments flattened and elongate, the anthers basifixed, 2-celled, longi- tudinally dehiscent; carpels numerous, separate, the styles comose. Fruit a dry arcuate-ellipsoid achene terminated by the elongate indurate, hirsute style, the ovule pendulous on the dorsal raphe.

    Vines , ± woody, sometimes only at base, climbing by means of tendril-like petioles and leaf rachises, or erect, herbaceous perennials, from elongate rhizomes. Leaves cauline, opposite, simple or compound, sessile or petiolate. Leaf blade undivided or 1-3-pinnately or -ternately compound; leaf or leaflets cordate to orbiculate, oblong, lanceolate, or oblanceolate, lobed or unlobed, margins entire or toothed. Inflorescences axillary and/or terminal, 1-many-flowered cymes or panicles or flowers solitary or in fascicles, to 15 cm; bracts present and leaflike or ± scalelike or absent, not forming involucre. Flowers bisexual or unisexual, radially symmetric; sepals not persistent in fruit, 4, white, blue, violet, red, yellow, or greenish, plane, ovate to obovate or linear, 6-60 mm; petals absent; sometimes anther-bearing staminodes between sepals and stamens; stamens many; filaments filiform to flattened; pistils 5-150, simple; ovule 1 per pistil; beak present. Fruits achenes, aggregate, sessile, lenticular, nearly terete, or flattened-ellipsoid, sides not prominently veined; beak terminal, straight or curved, 12-110 mm. X = 8.

    Vines woody or herbaceous and perennial, rarely erect shrubs, subshrubs, or perennial herbs. Leaves opposite, rarely fascicled or alternate, simple or compound; leaf or leaflet blades palmately veined. Inflorescences cymose, sometimes solitary, usually pedunculate, 2-bracteate. Flowers bisexual or unisexual. Sepals 4 or 5(--8), petaloid, spreading, ascending, or erect, usually valvate in bud. Petals absent. Stamens numerous, sometimes outer ones sterile and becoming linear or petaloid staminodes; anthers introrse. Carpels numerous, usually pubescent or villous; ovaries 1-ovuled; ovule pendulous. Style elongated after anthesis, rarely slightly or not elongated. Achenes usually ± bilaterally compressed; persistent style usually strongly elongated, plumose.
