NIGHTSHADE FAMILY 463 



this feature was briefly noted in the writer's Manual (1925). In early anthesis the sutures lie 

 very near the base of the oTary. During the period of maturation of the fruit this basal part 

 elongates conspicuously, although the upper portion or "cap" changes but little. Less abundant 

 than Lycium pallidum var. oligospermum, Lycium cooperi grows in the Mohave Desert mostly at 

 higher altitudes than that very different shrub.

 proved itself an undesirable weed in fields. Also at Eureka, Tracy 12,972, and 

 reported at Santa Cruz and Oaldand.
