 it is often called Checkerberry or Partridge-berry (names also applied to Mitch-

 pore. Capsule globular, 5-celled, 5-valvecl ; the many-seeded placentae borne 

 on the summit or middle of the columella. Seeds pendulous or spreading. 

 Shrubs, with umbelled, clustered, or panicled and racemed (mostly white)

 vate to lanceolate-oblong (1 -2' long), serrulate or entire; racemes crowded in

 Capsule oblong-pyramidal, 5-celled, 5-valved ; the many-seeded placentae at

 lated coat extended at both ends into awl-shaped appendages. A tree with
