 angustata. 



FIG. 155. Opuntia comonduensis. 



This species has long been known only from herbarium specimens collected by Mr. 

 Brandegee in 1889. In 1911 Dr. Rose collected considerable material both near the town 

 of San Jose and on Carmen Island which has since been in cultivation in the New York 

 Botanical Garden and in Washington. The above description is based largely on this 

 collection. 



This species sometimes grows with 0. tapona, in fact being confused in the original 

 material; except for its pubescent joints, they are not readily distinguished. 



Figure 155 is from a photograph by Mr. T. W. Smillie of a plant collected by Mr. E. W. 

 Nelson and Mr. E. A. Goldman in Lower California in 1906.
