Lathyrus pauciflorus flowers are a soft pink, fading (as shown below) to inky blues.  The plant, typical of member of its genus, often grows in extensive patches, commonly around and under Oaks and Ponderosas.  Tendrils at the leaf tips are tenacious.  Individual leaves are longer than broad, pointed, and widely spaced.  This is a very handsome plant that grabs your attention when it is in flower.

Under the large upright pink banners you can see the light-colored tip of the flower keel tucked into the pink/white wings of the flower.  The short keel is one of the diagnostic characteristics of this species.  In the upper right corner you can see the deeply cut calyx.  

Stems are often slightly winged, stipules (folded, leaf-like appendages at the center of the photograph) are noticeable, and leaves vary from about twice as long as wide (as shown at left) to about four times as long as wide (as shown in the first picture on this page).
