Plate XXVIII. 



QUKRCUS DUMOSA POLYCARPA, Greene. 



Remarks. On page 36 preceding I named and described the Santa Cruz Island 

 scrub oak here illustrated. The insular type will be seen to differ somewhat from the 

 original Q. dumosa in foliage and pubescence. The spicate inflorescence of perfect flowers 

 is now proven to be a mere accident. While in Temecula Cafion, San Diego County, late 

 in June last, I found ordinary Q. dumosa occasionally putting forth just such erect spicate 

 inflorescence, and observed it to be a peculiar second flowering of the shrub. The polycarpa 

 state is therefore a later abnormal inflorescence from a second growth of shoots. I 

 doubt if acorns are perfected from these later spicate and apparently perfect flowers.
