Jack's Pond is located in the city of San Marcos just north of the Coronado Hills in northern San Diego County, California. It contains floral elements from the freshwater marsh and riparian woodland plant communities. The surrounding hillsides are dominated by patches of disturbed grassland and dense coastal sage scrub vegetation, mixed with elements of the chaparral plant community. The pond and vicinity also contain numerous naturalized (weedy) species and escapes from cultivation. This interesting floristic area includes about 23 acres of undeveloped land and hiking trails, and has been preserved as a natural park within the City of San Marcos. Note: This list does not include all the many species of post-burn herbaceous wildflowers that appear in the coastal sage scrub and chaparral following fire, nor does it contain all of the ornamentals planted around the buildings at Jack's Pond.

Jack's Pond: Showing dense stand of California bulrush (Scirpus californicus) in foreground and Fremont cottonwoods (Populus fremontii) along distant shore.

The shoreline of Jack's Pond is dominated by California bulrush (Scirpus californicus) and cattails (Typha latifolia). The slopes in foreground contain coastal sage scrub mixed with elements from the chaparral, including black sage (Salvia mellifera), slender sunflower (Helianthus gracilentus) and chamise (Adenostoma fasciculatum). Father back from the pond are dense stands of California sagebrush (Artemisia californica), laurel sumac (Malosma laurina), lemonade berry (Rhus integrifolia) and red bush monkeyflower (Mimulus puniceus).

Red bush monkeyflower (Mimulus puniceus), one of the most colorful shrubs of the coastal sage scrub during late spring. Close-up view at right shows the white stigma in the opened and closed positions. The remarkable stigma is "thigmotrophic" and can close up rapidly with the slightest touch of your finger or an incoming pollinator, such as the bill of a hummingbird. This action decreases the chance of self pollination and favors cross pollination, especially if the incoming pollinator is covered with pollen from another monkeyflower blossom. When the bill or head of the hummingbird enters the blossom and touches the stigma it immediately closes. Pollen carried by the bird is trapped within the closed stigma lobes. As the bird probes for nectar deep in the corolla it also picks up fresh pollen from the anthers. But when it leaves, there is little chance of this newly acquired pollen touching the stigma because it is already closed, thus averting any self pollination. Note: In the Jepson Flora of California (1993), this species is listed under M. aurantiacus, in a complex hybridizing, intergrading population that includes a number of subpopulations that were considered separate species in older references. [Incl. M. puniceus, M. longiflorus, M. flemingii and M. aridus.]
