Abstract
Contribución al conocimiento de tres especies indias de
Spermacoce L. (Rubiaceae) e información preliminar de su
ecología de polinización.
Se han descrito caracteres taxonómicos no documentados para
Spermacoce hispida L. y Spermacoce articularis L. S. hispida es
bimórfica. Las flores son débilmente protándrica, nectaríferas y auto-polinizadoras.
Las mariposas, las abejas y los trips son importantes
como polinizadores. El conjunto de fruta natural más elevado
que se evidencia en estas especies se atribuye a autopolinización
y entomofilia. Los frutos la dehiscencia es septicida en S. hispida
y S. articularis, y circunscisa en Spermacoce pusilla Wall. La
dispersión de las semillas es anemo-, baro-, ombro- e hidrocórica.
Estas especies ocupan diferentes hábitats para evitar la competencia
por los polinizadores y maximizar la producción de semillas y
ampliar su rango de distribución.
Abstract Undocumented taxonomic characters have been described for Spermacoce hispida L. and Spermacoce articularis L. S. hispida is bimorphic. The flowers are weakly protandrous, nectariferous and self-pollinating. Butterflies, bees and thrips are important as pollinators. The highest natural fruit set evidenced in these species is attributed to auto-selfing and entomophily. Fruits dehisce septicidally in S. hispida and S. articularis and circumscissile mode in Spermacoce pusilla Wall. Seed dispersal is anemo-, baro-, ombro- and hydro-chorous. These species occupy different habitats to avoid competition for pollinators and maximize seed output and expand their distribution range.
