Leaves not marcescent, ± sessile; blade 5-20(-30) × 2-8(-15) mm, apex apiculate, covered with spreading, white, long hairs; basal with blade oblanceolate or obovate, narrowed proximally, sometimes spatulate; cauline with blade broadly ovate or elliptic-ovate. Inflorescences 3-50-flowered, aggregated into dense, cymose clusters or in more-open dichasia; bracts: proximal herbaceous, distal lanceolate, apex acute, with long, mainly eglandular hairs. Pedicels erect to spreading, often arcuate distally, 0.1-5 mm, shorter than capsule, glandular-pubescent. Flowers: sepals green, rarely dark-red tipped, lanceolate, 4-5 mm, margins narrow, apex very acute, usually with glandular hairs as well as long white hairs usually extending beyond apex; petals oblanceolate, 3-5 mm, rarely absent, usually shorter than sepals, apex deeply 2-fid; stamens 10; styles 5.

Hojas opuestas, ampliamente elípticas a orbiculares o espatuladas, 5–20 mm de largo y 3–12 mm de ancho, ápice obtuso, pilosas; sin estípulas. Cimas terminales densas, pedicelos 1–5 mm de largo, pilosos, a veces glandulosos; sépalos 5, lanceolados, 2.8–5.1 mm de largo, agudos, margen escarioso, pilosos, generalmente glandulosos; pétalos 5, levemente bilobados, casi tan largos como los sépalos, blancos; estambres 10, más cortos que los pétalos; estilos 5, libres. Cápsula cilíndrica, 5–8.8 mm de largo, sobrepasando al cáliz, curvada, dehiscente por dientes apicales; semillas finamente tuberculadas, 0.3–0.5 mm de diámetro, cafés.

    Conocida de Nicaragua por una colección (Williams 24948) de nebliselvas al norte de Santa María de Ostuma, Matagalpa; 1300–1500 m; fr feb; introducida de Europa, ampliamente distribuida en Norteamérica y en las montañas de México y Centroamérica. El nombre Cerastium viscosum L. ha sido usado para esta especie. Se estima que existen entre 60 y 100 especies en el género que es casi cosmopolita. La descripción anterior está basada principalmente en el trabajo de Good.

      Has been recorded by several collectors from Tanganyika: Lushoto District, near Amani, as an adventive. It is morphologically related to C. octandrum [Hochst. ex] A. Rich. from which it differs especially in having the lower (and rarely all) flowers without petals (nearly always); petals with generally a ciliate claw; sepals more glandular; stamens often only 5; placenta not branched or radiate; seeds 0.5 mm. in diameter. A standard specimen is: Verdcourt 301, in a drain around building with Ageratum, Galinsoga, Chloris, Oxalis, Pilea, and Drymaria, 1 Aug. 1950!
