    SYRINGODIUM Kütz.

    Syringodium filiforme Kütz. in Hohen., Alg. Mar. Exsicc. 9: no. 426. 1860; Cymodocea filiforme (Kütz.) Correll; C. manatorum Asch.

    Rizomas con 1 o más raíces y un tallo corto y erecto en cada nudo; tallos erectos con 2–3 hojas, abrazados por escamas escariosas, ovadas y agudas. Hojas sésiles; vaina 1.5–7 cm de largo, las aurículas obtusas; lámina linear, terete, frecuentemente adelgazada en la base, con 1 nervio central, 2–10 nervios periféricos y 2 lagunas. Inflorescencia cimosa, las ramas inferiores dicasias, las superiores monocasias; flores en las axilas de hojas reducidas y con la vaina hinchada; flores estaminadas pediceladas, cada una formada de 2 anteras, éstas adaxialmente connadas en la base y unidas al pedúnculo a la misma altura, pedicelo alargándose en la antesis; flores pistiladas sésiles, estilo corto y dividido en 2 estigmas largos. Frutos como aquenios, con pericarpo lapiloso, elipsoides a obovoides, cuadrangulares en sección transversal y con una inconspicua cresta media adaxial.

    Localmente abundante en aguas marinas poco profundas y de substrato arenoso, en Zelaya; fl y fr feb–may; Haynes 8642, Stevens 19907; ampliamente distribuida a lo largo de las costas del mar Caribe y del golfo de México. Un género con 2 especies, la otra restringida en su distribución al Océano Indopacífico. Cuando S. filiforme ocurre en comunidades con Halodule, S. filiforme normalmente se encuentra en aguas más profundas que Halodule. Los 2 géneros pueden separarse fácilmente, aún en condición estéril, porque las hojas de Syringodium son teretes mientras que las de Halodule son aplanadas.

    Plants herbaceous, perennial, submersed in saline water, dioecious. Rhi- zomes creeping, monopodial, with one or more roots and a short erect stem at each node. Leaves 2-3 on each stem, divided into a sheath and a blade; sheath broad, persisting longer than the blade, leaving open circular scars when shed, bi-auriculate, stipulate, the auricules obtuse; blades linear, often narrowed at the base. Inflorescence cymose, the lower branches dichasial, the upper mono- chasial. Flowers axillary to a reduced leaf, the sheath of which is inflated; peri- anth absent; staminate flowers stalked, each consisting of 2 anthers dorsally con- nate at their lower parts and attached at the same height on the stalk; carpellate flowers sessile, each consisting of 2 distinct ovaries, each with a short style which divides into 2 long stigmata. Fruits achene-like with a stony pericarp, ellipsoid to obovoid, quadrangular in cross section and with an inconspicuous dorsal me- dian ridge.
