14. Caryophyllaceae, the Pink Family
1. Cerastium L.--Mouse-ear chickweed
1. Cerastium brachypodum (Engelm. ex A. Gray) Robins.
Short glandular-pubescent plant 0.5-3.5 dm tall; stems simple or branched
from the base. Leaves 5-30 mm long, 1.5-5 mm wide. Flowers in
rather compact cymes; sepals 2.5-4 mm long; petals, if present,
shorter than to exceeding the sepals, often absent. Capsules 6-10 mm
long; pedicels 0.5-1.25X the length of the calyx in flower, to 3X the
calyx length and straight or only slightly curved in age. Seeds reddish-brown,
angular-obovoid, papillate, 0.4-0.5 mm long. Late May--Jul. Wet alkali flats
and drier places, often where sandy; occasional; (N.S. to Mack., s to GA, TX,
AZ and OR).
C. brachypodum is sometimes treated as a variety of the following
species. Although their largely sympatric ranges may lend credence to that
interpretation, the two do seem quite distinct on the basis of habitat selection
and morphology in the northern Great Plains and are thus viewed here as separate
