14. Conium L.

Por L. Constance y J. Affolter.

Hierbas perennes, delgadas a robustas, caulescentes, ramificadas, glabras y algo glaucas, con raíces axonomorfas robustas o raíces carnosas fasciculadas. Hojas alternas, pecioladas, pinnadamente compuestas con folíolos pinnadamente incisos o disecados, membranáceas; pecíolos envainadores, las vainas escariosas. Inflorescencia de umbelas laxas compuestas; pedúnculos terminales y laterales; involucro generalmente de 5 brácteas escarioso-marginadas, finalmente reflexas; radios escasos, patente-ascendentes a reflexos; involucelo de 5 bractéolas como brácteas; pedicelos delgados, patente-ascendentes. Dientes del cáliz ausentes; pétalos de ápice inflexo más angosto, blancos o blanco-verdosos o blanco-amarillentos; estilos cortos, el estilopodio bajo cónico. Frutos anchamente ovoides a subglobosos, comprimidos lateralmente y más o menos constrictos en la comisura, glabros; mericarpos subteretes; carpóforo bipartido; costillas 5, conspicuas, obtusas, frecuentemente unduladas, subiguales; vitas ausentes, un anillo de tejido secretor rodeando la cavidad de la semilla; cara de la semilla sulcada. Al menos 4 spp. Europa al S. de África; el taxon siguiente adventicio en todo el mundo.

    Herbs, biennial or shortly perennial, slender. Root stout, long-conic. Stem hollow, erect, much-branched above, conspicuously purple-spotted. Leaves petiolate, narrowly sheathing at base; blade 2–3-pinnate, finely dissected. Umbels numerous, terminal and lateral on dichotomous branches; bracts and bracteoles several, often reflexed; rays numerous, ascending; rays numerous, spreading widely. Calyx teeth obsolete. Petals white or yellowish white, obovate or obcordate, apex incurved. Stylopodium low-conic, styles short, reflexed. Fruit ovoid or broad-ovoid, slightly flattened laterally; ribs 5, prominent, all ridged to very narrowly sinuate-winged; vittae small, numerous, completely encircling the seed, usually broken down in mature fruit. Seed face deeply concave or sulcate. Carpophore 2-cleft, at least to middle.

    Morphology

    Mericarps with prominent ribs, which are often undulate; vittae 0. Stylopodium depressed; styles short and recurved. Fruit ovoid to suborbicular, somewhat laterally compressed, with a fairly narrow commissure. Petals white, usually with a slightly inflexed apex. Calyx teeth obsolete. Umbels compound, with well-developed bracts and bracteoles, which are sometimes semi-caducous. Glabrous, biennial herbs up to 2 m. Leaves compound-pinnately divided, with rather fine ultimate segments.
