Low, spreading plant with tiny white flowers.  The flowers have 5 petals, but each petal is so deeply divided into two, that there often appear to be 10 petals.  Sometimes petals may not be divided, and sometimes the petals are lacking.  The leaves are egg-shaped, and opposite each other.  Upper leaves are nearly stalkless, but lower leaves have long stalks. 

Non-native weed, very common in shady patches along the bikeway and Wildwood Drive, as well as along the trails on the western slope of the Park.  Outside the park, a common weed in yards and gardens.

The native, star chickweed (Stellaria pubera), has larger, conspicuous flowers, and leaves that are much longer.  It is common in the woodland on the western slope of the Park.
