Abstract

Developmental patterns, developmental sequence, deposition of secondary wall material, and maturation of macrosclereids and osteosclereids were similar in Desmodium canadense and Cassia fasciculata. Both species apparently lack a well-defined strophiolar region. Two distinct differences were observed in the mature seed coat. One is the presence of a single row of macrosclereids in the hilar region of Cassia fasciculata and a double row of macrosclereids in the hilar region of Desmodium canadense. The second is the appearance of "spicule-like" structures, apparently enveloped laterally by a cellulosic matrix in the cuticularized layer of Cassia fasciculata.
