RANUNCULUS FICARIA (RANUNCULACEAE), NATURALIZED IN TEXAS

r anunculus ficaria is naturalized along a creek in Tarrant Co, Texas. The plants produce axillary bulbils and infertile achenes and per haps are best identified as subsp. bulbifera , although other morphological features do not closely accord with previous descriptions of that subspecies. resumen r anunculus ficaria esta naturalizado a lo largo de un arroyo en Tarrant Co, Texas. Las plantas producen bulbillos axilares y aquenios infertiles y quizas esten mejor identificados como subsp. bulbifera , aunque otras caracteristicas morfologicas no esten muy de acuerdo con las descripciones previas de esa subespecie. A population of r anunculus ficaria L. (lesser celandine, fig buttercup) was discovered in flower immediately adjacent to Overton Creek in Fort Worth’s Overton Park, near the center of the city. The creek at this point runs through a broad but relatively steep-sided ravine and is about three miles above confluence with the Trinity River. Tributaries of Overton Creek pass through several miles of urban neighborhood upstream from this area. The creek commonly rises beyond its banks in heavy rain. Thirty discrete plants, clearly naturalized, grow in an area of about 30 square feet—the largest produced at least 20 flowers. A second population of five scattered plants occurs on the stream terrace about 300 yards downstream.
