Cedrela DuGEsn. The fruit of the uncertain species mentioned 

 on page 335, since received from Prof. Duges, permits a fuller de-

 inches long, rather thin, entire, the veins rusty and sliglitly pubescent

 than the calyx; corolla 2^- lines long, pubescent: fruit oblong, about 

 an inch long : seeds with the wing scarcely as long as the body, 3 lines 

 broad or less.

 Lorenzo de Laguna, Coahuila (169).
